Palkhivala	 Dr. D. Pal	 U.K. Khaitan	 S.R. Agar wal and Parveen Kumar for the Appellant. V.P. Raman	 Addl. General	 T.A. Ramachandran and R.N. Sachthey for the Respondents. 764 The Judgment of the Court was delivered by GOSWAMI	 J. These two appeals by certificate are from the judgment of the Calcutta High Court since reported in Commissioner Income tax	 West Bengal I vs Textile Machinery Corporation( '). The two appeals relate respectively to two assessment years 1958 59 (calendar year 1957) and 1959 60 (calendar year 1958). The matter relates to the claim by the assessee for exemption of tax under section 15C of the Indian Income tax Act	 1922 (briefly the Act). The matter came u13 before the High Court 'on a refer ence under section 66(1) of the Act. The two questions referred to were as follows : "(1) Whether	 on the facts and in the circumstances of the case	 the Tribunal was right in holding that the Steel Foundry Division was an industrial undertaking to which section 15C of the. Indian Income tax Act	 1922	 applied ? (2) Whether	 on the facts and in the circumstances of the case	 the Tribunal was right in holding that the Jute Mill Division set up by the assessee company was an indus trial undertaking to which section 15C of the Indian Incometax Act	 1922	 applied ? The facts may briefly be stated: The assessee (the appellant herein) is a heavy engineer ing concern manufacturing boilers	 machinery parts	 wagons	 etc. For the assessment years 1958 59 and 1959 60 the assessee claimed exemption of tax under section 15C of the Act in respect of the profits and gains derived from its Steel Foundry Division and a similar claim for relief under section 15C in respect of its profits and gains derived from its Jute Mill Division for the year 1959 60. The assessee had previously in the earlier years bought from outside the castings manufactured in the Steel Foundry Division which was started in the assessment year 1958 59 and continued thereafter. Again	 similarly in the year '1959 60	 in addition to the manufacturing of castings in the Steel Foundry Division the assessee started the Jute Mill Division where the parts made out of the raw material supplied by the Boiler Division by machining and forging them were given to the Boiler Division of the assessee. It was found that out of a total sale of Rs.28	23	127/ of steel castings goods worth Rs.18	39	433/ were used in connection with the various Divisions of the company. In respect of the Jute Mill Division	 the Incometax Officer found that out of the total sales of Rs.13	03	509/ sales. to the Boiler Division totalled Rs.11	89	812/ and sales to outside the Jute Mill Division totalled only a sum of Rs.1	13	6971/ . The Income tax Officer and the Appellate Assistant Commissioner	 on the above facts	 held the under takings as expansion and reconstruction of the business already existing and hence the assessee was not entitled (1) 765 to exemption under section 15C of the Act. The Income tax Appellate Tribunal	 however	 allowed the appeal of the assessee and accepted the claim for exemption under section 15C. According to the Tribunal both the Steel Foundry and the Jute Mill Division of the assessee were new industrial undertakings. The above conclusion was reached on the basis of several facts found by the Tribunal. These arc that the machinery was new	 was housed in a separate building and that industrial licences had to be obtained	 for manufactur ing the parts in question. According to the Tribunal the existing business of the assessee consisted of manufacturing boilers	 wagons	 etc. and for that purpose the assessee was purchasing the spare parts	 forgings and castings from outside. The Tribunal came to the conclusion that the business of the new industrial undertakings was to manufac ture those very spare parts. Hence the Tribunal concluded that it could not be said that the undertakings were formed out of the existing 'business to come within the mischief of the exclusion clause in section 15C(2)(i). The Tribunal rightly relying upon the Tara Iron and Steel Co. Ltd. and Others vs State of Bihar(1) also held that even though the manufactured products of the new industrial undertakings were mostly used in the assessee 's other business of manu facturing boilers	 wagons	 etc. the element of profit was there and the extent of the same could be ascertained as the assessee was maintaining separate books of account. In the reference at the instance of the Department the High Court answered both the questions in the negative and against the assessee. The High Court held as follows : "The goods which the steel foundry division and the jute mill division began producing for the assessee were also previous ly used by the assessee in its business	 but they were purchased from outside and this purchase from outside was replaced by produc tion or manufacture from within the asses see 's own business. This change of producing one 's own goods systematically used in the existing business instead of buying them from outside would only be a reconstruction of a business already in existence . In so far as they started producing and manufactur ing themselves	 the assessee was doing some thing which was only a reconstruction of the business already in existence . . The newness of the machinery of the steel foundry division and the jute mill division could not by itself make them new industrial undertakings. Separate housing of	 and separate accounts for	 the steel foundry division and jute mill division may be only parts of reconstruction of the same business and did not necessarily indicate a new indus trial undertaking. The grant of a special licence for the steel foundry division did not make it an industrial undertaking to qualify for exemption from tax under section 15C	 because the licence was for expansion of the existing industrial undertaking and the licence did not cover the jute mill division". (1) 766 It is	 however	 admitted before us that both the units were covered by licences. The controversy in these appeals centres round the true construction of section 15C(2)(i) of the Act and in particu lar with regard to the scope and ambit of the expression therein	 namely	 the reconstruction of business already in existence. Is the High Court right in holding that the two industrial undertakings	 namely	 the Steel Foundry and the Jute Mill Division	 are formed by reconstruction of the business already in existence differing from the con trary conclusion reached by the Tribunal ? Before we proceed further	 we will read section 15C as it stood during the material time: "15C. Exemption from tax of newly estab lished industrial undertakings. (1) Save as otherwise hereinafter provided	 the tax shall not be payable by an assessee on so much of the profits or gains derived from any industrial undertaking to which this section applies as do not exceed six per cent per annum on the capital employed in the undertaking computed in accordance with such rules as may be made in this behalf by the Central Board of Revenue. (2) This section applies to any industrial undertaking which (i) is not formed by the splitting up	 or the reconstruction of	 business already in existence or by the transfer to a new business of building	 machinery or plant	 previously used in any other business; (ii) has begun or begins to manufacture or produce articles in any part of taxable territories at any time within a period of thirteen years from the 1st day of April 1948	 or such further period as the Central Govern ment may	 by notification in the Official Gazette	 specify with reference to any partic ular industrial undertaking; (iii) employs ten or more workers in a manufacturing process carried on with the aid of power	 or employs twenty or more workers in a manufacturing process carried on without the aid of power; Provided that the Central Government may	 by notifica tion in the Official Gazette	 direct that the exemption conferred by this section shall not apply to any particular industrial undertaking. 767 (3) The profits or gains of an industrial undertaking to which this section applies shall be computed in accordance with the provisions of section 10. (4) The tax Shall not be payable by a shareholder in respect of so much of any dividend paid or deemed to be paid to him by an industrial undertaking as is attributable to that part of the profits or gains on which the tax is not payable under this sec tion. (5) Nothing in this section shall affect the application of section 23A in relation to the profits or gains of an industrial under taking to which this section applies. (6) The provisions of this section shall apply to the assessment for the financial year next following the previous year in which.the assessee begins to manufacture or produce articles and for the four assessments immediately succeeding". We are principally concerned in these appeals with clause (i) of sub section (2) of section 15C and that also only with one part of it	 namely	 whether the industrial undertakings	 Steel Foundry and the Jute Mill Division	 are not formed by the reconstruction of the business already in existence. The learned Additional Solicitor General submits that these two undertakings are not entitled to exemption under section 15C(2) as rightly so held by the High Court since they were formed by the reconstruction of the assessee 's business already in existence	 namely	 the business of heavy engineering. He submits that setting up of a separate unit to do something in the course of pre existing manufacturing process to aid the production of the same article as was being produced by the pre existing industrial undertaking would not amount to starting of a new industrial undertak ing. He further emphasises that production of the articles in the Steel Foundry and in the Jute Mill Division is only ancillary activity to the main business of the assessee and since the articles produced in these two supplemental undertakings help in producing the identical article which has been the end product of the assessee 's main business	 section 15C(2) (i) cannot come to the aid of the assessee. According to Mr	 Raman these two industrial undertakings cannot be said to be not formed out of the reconstruction of the business already in existence. Section 15C(2)(i) only excludes three categories of industrial undertakings from the benefit of the section without referring to clauses (ii) and (iii) of that sub section and other limiting provisions of the section which are not applicable in the instant case. It is contended by Mr. Palkhivala that acceptance of the Additional Solicitor General 's submission will amount to adding a fourth category of cases in sub section (2)(i)	 namely	 an industrial under 768 taking which is an ancillary undertaking manufacturing certain articles to supplement the principal industrial activity. This	 says Mr. Palkhivala	 will be adding something to the section. Section 15C is an exemption section. The benefit grant ed under this section is a partial benefit so far as the quantum of the exempted profits of the new industrial under taking as also for a limited period or periods as specified in the section. If the two industrial undertakings	 about the existence of which there can be no controversy	 as found by the Tribunal	 cannot be held to. be formed by the recon struction of the business already in existence	 the benefit of section 15C will be available to the assessee. The principal object of section 15C is to encourage setting up of new industrial undertakings by offering tax incentive within a period of 13 years from April 1	 1948. Section 15C provides for a fractional. exemption from tax of profits of a newly established undertaking for five assessment years as speci fied therein. This section was inserted in the Act in 1949 by section 13 of the Taxation Laws (Extensions to Merged States and Amendment) Act	 1949 (Act 67 of 1949) extending the benefit to the actual manufacture or production of arti cles commencing from a prior date	 namely	 April 1	 1948. After the country had gained independence in 1947 it was most essential to give fillip to trade and industry from all quarters. That seems to be the background for insertion of section 15C. It is also significant that the limit of the number of years for the purpose of claiming exemption has been pro gressively raised from the initial 3 years in 1949 to 6 years in 1953	 7 years in 1954	 13 years in 1956 and 18 years in 1960. The incentive introduced in 1949 has been thus stepped up ever since and the only object is that which we have already mentioned. Under sub section (1) of section 15C the tax shall not be payable by an assessee on profits not exceeding six per cent per annum on the capital employed in the new industrial undertaking from the profits which alone exemption is claimed. Sub section (2) of section 15C has a negative as well as a positive aspect. Negatively	 the new industrial undertaking of the assessee should not be formed (1) by the splitting up of the business already in existence	 (2) by the reconstruction of business already in existence	 or (3) by the transfer to a new business of building	 machinery or plant used in a busi ness which was being carried on before April 1	 1948. We agree that it is not possible to exclude any new indus trial undertaking other than the three categories mentioned above. 769 We are concerned in these appeals with the type No. (2) mentioned above. Positively	 the new industrial undertaking must produce result	 that is to say	 it has to manufacture or produce articles at any time within a period of 13 years from April 1	 1948. The further requirement under sub section (2) is with regard to the personnel in the under taking	 namely	 that ten or more workers have to work in the manufacturing process carried on with the aid of power or twenty or more workers have to carry on work without the aid of power. The above element with regard to the number of workers engaged in the undertaking would go to. show that even small industrial undertakings	 newly started	 are within the exemption clause	 where	 for example	 twenty workers may complete the industrial process without the aid of power. There is no controversy about the .positive aspects in 'these appeals. Again	 the new undertaking must not be substantially the same old existing business. The third excluded category mentioned above significant. Even if a new business is carried on but by piercing the veil of the new business it is found that there is employment of the assets of the old business	 the benefit will be not available. From this it clearly follows that substantial investment of new capital is imperative. The words "the capital employed" in the principal clause of section 15C are significant	 for fresh capital must be employed in the new undertaking claiming exemption. There must be a new under.taking where substan tial investment of fresh capital must be made in order to enable earning of profits attributable to that new capital. The assessee continues to be the same for the purpose of assessment. It has its existing business already liable to tax. It produced in the two concerned undertakings commodi ties different from those which it has been manufacturing or producing in its existing business. Manufacture of produc tion of articles yielding additional profit attributable to the new outlay of capital in a separate and distinct unit is the heart of the matter	 to earn benefit from the exemption of tax liability under section 15C. Sub section (6) of the section also points to the same effect	 namely	 production of articles. The answer	 in every particular case depends upon the peculiar/acts and conditions of the new industrial undertaking on account of which the assessee claims exemp tion under section 15C. No hard and fast rule can be laid down. Trade and industry do not run in earmarked channels and particularly so in view of manifold scientific and technological developments. There is great scope for expan sion of trade and industry. The fact that an assessee by establishment of a new industrial undertaking expands his existing business	 which he certainly does	 would not	 on that score	 deprive him of the benefit under section 15C. Every new creation in business is some kind of expan sion and advancement. The true test is no.t whether the new industrial undertaking connotes expansion of the exist ing business of the assessee but whether it is all the same a new and identifiable undertaking separate and distinct from the existing business. No particular decision in one case can lay down an inexorable test to determine whether a given case comes under section 15C or not. In order that the new undertaking can be said to be not formed out of the already existing business	 there 770 must be a new emergence of a physically separate industrial unit which may exist on its own as a viable unit. An undertakings is formed out of the existing business if the physical identity with the old unit is preserved. This has not happened here in the case of the two undertakings which are separate and distinct. It is clear that the principal business of the assessee is heavy engineering in the course of which it manufactures boilers	 wagons	 etc. If an industrial undertaking produce certain machines or parts which are	 by themselves	 identi fiable units being marketable commodities and the undertak ing can exist even after the cessation of the principal business of the assessee	 it cannot be anything but a new and separate industrial undertaking to qualify for appropri ate exemption under section 15C. The principal business of the assessee can be carried on even if the said two addi tional undertakings cease to function. Again	 the con verse is also true. The fact that the articles produced by the two undertakings are used by the Boiler Division of the assessee will not weigh against holding that these are new and separate undertakings. On the other hand the fact that a portion of the articles produced in these two new indus trial undertakings had been sold in the open market to others is a circumstance in favour of the assessee that the new industrial units can function on their own. Use of the articles by the assessee is not decisive to deny the benefit of section 15C. Section 15C partially exempts from tax a new industri al unit which is separate physically from the old one	 the capital of which and the profits thereon are ascertainable. There is no difficulty to hold that section 15C is applica ble to an absolutely new undertaking for the first time started by an assessee. The cases which give rise to controversy are those where the old business is being car ried on by the assessee and a new activity is launched by him by establishing new plants and machinery by investing substantial funds. The new activity may produce the same commodities of the old business or it may produce some other distinct marketable products	 even commodities which may feed the old business. These products may be consumed by the assessee in his old business or may be sold in the open market. One thing is certain that the new undertaking must be an integrated unit by itself wherein articles are pro duced and at least a minimum of ten persons with the aid of power and a minimum of twenty persons without the aid of power have been employed. Such a new industrially recognisa ble unit of an assessee cannot be said to be reconstruction of his old business since there is no transfer of any assets of the old business to the new undertaking which takes place when there is reconstruction of the old busi ness. For the purpose Of section 15C the industrial units set up must be new in the sense that new plants and machin ery are erected for producing either the same commodities or some distinct commodities. In order to deny the benefit of section 15C the new undertaking must be formed by recon struction of the old business. Now in the instant case there is no formation of any industrial undertaking out of the existing business since that can take place only when the assets of the old business are transferred substantially to the new undertaking. There is no such transfer of assets in the two cases with which we are concerned. 771 We will now deal with the question whether the two undertak ings the assessee are formed by reconstruction of the exist ing business. The word 'reconstruction ' is not defined in the Act but has received judicial interpretation. In re South African Supply and Cold Storage Company	 Wild vs Same Company(1)	 Buckley	 J. dealing with the meaning of the word 'reconstruction ' in a company matter observed as fol lows : "What does 'reconstruction ' mean ? To my mind it means this. An undertaking of some definite ' kind is being carried on	 and the conclusion is arrived at that it is not desirable to kill that undertaking	 but that it is desirable to preserve it in some form	 and to do so	 not by selling it to an outsider who shall carry it on that would be a mere sale but in some altered form to continue the undertaking in Such a manner as that the persons now carrying it on will substantially continue to carry it on. It involves	 I think	 that substantially the same business shall be carried on and substantially the same persons shall carry it on. But it does not involve that all the assets shall pass to the new company or resuscitated company	 or that all the shareholders of the old company shall be shareholders in the new company or resusci tated company. Substantially the business and the persons interested must be the same". This concept of reconstruction was accepted by the Bombay High Court in the Commissioner of Income tax	 Bombay City I vs Gaekwar Foam and Rubber Co. Ltd. (1)	 dealing with section 15C of the Act. While adverting to the passage which we have just quoted the Bombay "Now fully appreciating the distinction which counsel for the Revenue has sought to make between the case of a reconstruction of a company and the case of reconstruction of a business	 these observations	 as we read them	 are equally illuminating in the context of reconstruction of business already in existence in the case of a newly established industrial undertaking". The Delhi High Court also in Commissioner of Income tax vs Gangs Sugar Corpora tion Ltd.(a)	 accepted the above concept of 'reconstruction ' in the following passage : "We have given the matter our earnest consideration and are of the view that in the reconstruction of business	 as in the reconstruction of a company	 there is an element of transfer of assets and of some change	 however partial or restricted it may be	 of ownership of the assets. The transfer	 however	 need not be of all the assets. It is none the less impera tive that there should be continuity and preservation of the old undertaking though in an altered form. (1) (3) 772 The concept of reconstruction of business would not be attracted when a company which is already running one industrial unit sets up another industrial unit. The new indus trial unit would not lose its separate and independent identity even though it has been set up by a company which is already running an industrial unit before the setting up of the new unit". We endorse the above views with regard to reconstruction of business. Reconstruction of business involves the idea of substan tially the same persons carrying on substantially the same business. It is stated on behalf of the Revenue that the same company in the instant case continues to do the same business of heavy engineering no matter certain spare parts necessary as components to completion of the end product are now manufactured in the business itself. The fact that the assessee is carrying on the general business of heavy engineering will not prevent him from setting up new industrial undertakings and from claiming benefit under section 15C if that section is otherwise applicable. Howev er	 in order to be entitled to the benefit under ' section 15C	 the following facts have to be established by the assessee. subject always to the time schedule in the section : (1) investment of substantial fresh capi tal in the industrial undertaking set up	 (2) employment of requisite labour therein	 (3) manufacture or production of articles in the said undertaking	 (4) earning of profits clearly attributa ble to the said new undertaking	 and (5) above all	 a separate and distinct identity of the industrial unit set up. We may add that there is no bar to an assessee carrying on a particular business to set up a new industrial undertaking on account of which exemption of tax under section 15C may be claimed. The legislature has advisedly refrained from inserting a definition of the word 'reconstruction ' in the Act. Indeed	 in the infinite variety of instances of restructuring of industry in the course of strides in technology and of other developments	 the question has to be left for decision on the peculiar facts of each case. If any undertaking is not formed by reconstruction of the old business that undertaking will not be denied the benefit of section 15C simply because it goes to expand the general business of the assessee on some directions. As in the instant case	 once the new industrial undertakings are separate and independent production units ' in the sense that the commodities produced or the results achieved are commercially tangible products and the undertakings can be carried on 773 separately without complete absorption and losing their identity in the old business	 they are not to be treated as being formed by reconstruction of the old business. The business of the assessee is of heavy engineering. The two new undertakings are independently producing arti cles which may be of aid to the principal business but yet the undertakings are distinct and not reconstruction out of the existing business of the assessee. Use by the assessee of the articles produced in its existing business or the concept of expansion are not decisive tests in construing section 15C. The High Court is not right in holding the two undertakings as formed by reconstruction of the existing business of the assessee. Several decisions have been cited at the bar before us. We approve of the conclusions in Commissioner of In come tax vs Ganga Sugar Corporation Ltd. (supra); Rajeswari Mills Ltd. vs Commissioner of income tax	 Madras(1); Nagar das Bechardas & Brothers P Ltd. vs Commissioner of Income tax Gujarat (2); Commissioner of Income tax	 West Bengal I vs Electric Construction and Equipment Company Ltd.(3); Commissioner ofIncome tax vs Hindusthan Motors Limited(4). The decision in Commissioner of Income tax vs Naya Sahitya(5) does not represent the correct legal position and	 hence	 cannot be approved. We may observe that we are not required to consider in these appeals how profit will be actually calculated in order to determine the quantum of exemption of six per cent of the profit on the capital employed. If difficulties are insurmountable and	 therefore	 profit cannot be ascer tained	 that will be a different question in the course of practical application of the section. That kind of a possi ble difficulty should not weigh in the true construction of section 15C. In the present case the assessee claimed profit and there was no difficulty about ascertainment of the exempted profit as separate books of accounts were kept and the undertakings were at separate places. In view of the foregoing discussion	 we are clearly of opinion that the High Court is not right in answering the two questions in the negative and against the assessee. On the other hand. the Tribunal was right in answering the two questions in the affirmative and against the Department. The two questions referred stand answered in the affirma tive. The judgment of the High Court	 is	 therefore	 set aside and the appeals are allowed with costs. P.B.R. Appeals allowed. (1) (2) (3) (4) [1976] Taxation Law Reports.

Section 15C of the Indian Income tax Act 1922	 which deals with exemption from tax of newly established industri al undertakings	 provides in sub section 2(i) that the section applies	 among others	 to any industrial undertaking which is not formed by the splitting up	 or the reconstruction of business already in existence. The assessee (appellant) was a heavy engineering con cern manufacturing boilers. machinery parts and wagons. In addition	 it had started a Steel Foundry Division and a Jute Mill Division. The bulk of the goods produced in both the divisions was used in the various divisions of the assessee company. The assessee 's claim for exemption from tax under section 15C in respect of profits derived from both the companies was rejected by the Income tax Officer and its appeal was rejected by the Appellate Assistant Commissioner on the ground theft the .undertakings were an expansion and recon struction of the existing business. On appeal	 the Appellate Tribunal held that although the products manufactured in the two divisions were used in the assessee 's business	 the Steel Foundry and the Jute Mill Division were new industrial undertakings	 in that the machinery used in them was new	 they were housed in separate buildings	 were: established under separate licences and that both the new divisions were maintaining separate books of account. On reference	 the High Court held that it was a case of reconstruction of the existing business because the goods produced in the two divisions were primarily used in the assessee 's engineering concern. Allowing the appeal. HELD: The Tribunal was right in holding in favour of the assessee. Section 15C is applicable to an absolutely new undertaking for the first time started and in order to deny benefit of the section	 the	 new undertaking must be formed by reconstruction of the old business. [768 B C] 1. (a) In order to be entitled to the benefit of section 15C	 the assessee has to establish: (1) the investment of substantial fresh capital in the industrial undertaking; (2) employment of the requisite labour therein (3) manufacture or production of articles in the under taking; (4) earning of profits 'clearly attributable to the new undertaking; and (5) separate and distinct indentity of the industrial unit set up. (b) Once the new industrial undertakings are separate and independent production units in the sense that the commodities produced or the results achieved are commercial ly tangible products and the undertakings can be carried on separately without complete absorption and losing their identity in the old business	 they are not to be treated as being formed by reconstruction of the old business. [772 H	 773 A] 763 (c) The object of the section is to encourage the setting up of new industrial undertakings by offering tax incentives within a certain period. Sub section (2) has a negative as well as a positive aspect. Negatively	 a new undertakings should not be formed by splitting up of the business already in existence and by the reconstruction of business already in existence; and positively	 a new undertaking must produce results	 that is to say	 it has to manufacture or produce articles at any time within the stipulated period. The new undertaking must not be substan tially the same as the existing business. The words "the capital .employed" are significant	 for	 fresh capital must be employed in the undertaking claiming exemption. Manufac ture or production of articles yielding additional profits attributable to the new outlay of capital in a separate and distinct unit is the heart of the matter to earn the benefit from the exemption of tax liability under section 15C. The fact that by establishing a new industrial undertaking the asses see expands its existing business would not deprive it of the benefit under section 15C. If an industrial undertaking produces certain machines or parts which are identifiable units being marketable commodities and the undertaking can exist even after the cessation of the principal business of the assessee	 it cannot be anything but a new and separate industrial undertaking to qualify for appropriate exemption under section 15C. [769 E H	 770A] In the instant case	 the principal business of the assessee can be carried on even if the two additional undertakings cease to function. The fact that a portion the articles produced in the new undertakings had been sold in the open market to others is a circumstance in favour of the assessee that the new industrial units can function on their own. Use of the articles by the assessee is not decisive 10 deny the benefit of section 15C. There was no 'formation of any indus trial undertaking out of the existing business since that can take place only when the assets of the old business are transferred substantially to the new undertaking. there 	ins no difficulty about ascertainment of the exempted profit as separate books of accounts were kept and the undertakings were at separate places. [770 B D. G H] The High Court was not right in holding that the two undertakings were formed by reconstruction of the existing business of the assessee. [773 B C] 2. Reconstruction involves that substantially the same business shall be carried on and substantially the same persons shall carry it on. But it does not involve that all the assets shall pass to the new company or resus citated company	 or that all the shareholders of the old company shall be shareholders in the new company. Substan tially the business and the person interested must be the same. [771 C D] South African Supply and Cold Storage Company Wild vs Same Company	 	 followed.
