Using Wastes and BiProducts, ;,

Washington, July 19.-An important dealing with the utilization of wastes and by-products in manufactures and show ing the great strides that have been made in this branch of industry during the past decade will soon be issued by the manufacturers division of the census bul eau. The report was prepared by Henry G. Kittridge, of Boston, we'll known expert in manufacturing pros cefses.
 The paper Is not in the nature of a sta- tistical report, but it covers a subject so intimately related to the development of the manufacturing industries of the country, and regarding which so little is known by the general public, that the officials of the census bureau deemed it desirable to publish it in connection with a census of manufactures.
 While methods and processes for uti- lizing wastes and by-products have been constantly developed for many years past. it appears from MT. Kittredges re- port that the advances made in this di- rection during the last decade have been particularly notable and advantageous in the economy of manufacturing
 Report of statistlcian.
 Chief Statician North says in his let ter of transmittal to director of the cen sus that while 1t Is impossible to meas uro satisfactorily the addition to the wealth of the country created by turn ing to some useful purpose the residues pd hv-y thrown away or left to rot, the material thus preserved and turned to some use- full account is enormous and in every instance cited in the report this utiliza- ton has resulted in a definite cheapening of the ccst of the product to the con- sumner. MT. North says:
 The subject is one that is yitally asso- ciated with the progress of every if- dustry and inseperably connected with the development and prosperity of every form of manufacturing. It has engaged the time and attention or the chemist and ircited the ingenuity of tho inventor and the skill of the artisan to effect eco- monies and reveal new utilities. No branch of science has been appealed to and relied upon so consistently as chem istry."
 Mir North says it would be assuming toe much to declare that the profitable employment of wastes in manufacturing has approximated the highest point to which science is capable of carrying it.
 This point will probably never be reached, and further developments must be expected" he says "evcn to the ex- tent of converting by-products into the main products of an industry This re- version is exemplified in notable n- stances within the last decades of the nineteenth century, the most conspicuous of which is to be seen Tn the revelations of coal tar and the highly developed utilization of the many by-products.
 Utilizing Despsed Materials.
 What has taken place within the last 100 years must be accepted more as a forerunner, prelude, of what is to come in the arts of manufacturing by the em- ployment of materials now held in low estimation as contributary to a high standard of manufacture.
 MT. Kittredge says that while the choicest perfumes placed on the market are made from oils and eithers extracted from flowers, there are many others which are artificially made out of bad smelling elements.
 The fusel oil obtained in the distillation of spirits has an odor that Is peculiarly disagreeable, yet it is used after treat ment with proper acids and oxidizing agents in making the oil of apples and the oil of pears. and in addition the oil of
