TO KILL SAN JOSE SCALE.
New Preparation Recommended b,
 Storrs Experiment Station.

St0rrs Experiment Station.
 Bulletin No 40 of the agricultural
 experiment station at Storrs describes
 and recommends a new petroleum
 emulsion for the destruction of San
 Jose scale. It has been tested for q
 year at Storrs and found highly ef- fective and very moderate in price It has also been tested and found ef- fective by J. H. Hale of South Glas- tonbury and Barnes brothers of Yales- vile.
 The bulletin gives at greater length the facts which have been condensed as follows:
 The formula, which consists of two parts follows:
 1.-The Emulsfier.
 Carbolic acid (crude liquid 100 per
 cent ? quarts Fish oil Dure Menhaden or wbale
 olD .................. 21a quarts Caustic potash (granulated). pound
 Heat to 300 degrees F., remove from the fire and immediately add
 Nerosene ............... 3A quarts Water ...................5 51a quarts
 Very serious difficulty has been ex- perienced ill getting materials of tho proper grade. This is especially true with regard to the local dealers who are not familiar with the requirements and who are likely to substitute something just as good"
 The emulsifier may be made LID in any quantity and kept indefinitely. The cooking is best done in an iron kettle equipped with a cover and so arranged that it can be readily re moved from the fire The mixture be- ing infiammable. it is unsafe to do the cooking near a building.
 2.-The Complete Soluble oil. water ................... l part Emulsifier ................., s parts Crude petroleum ......... IS parts hosln OH I parts
 This part of the formula may be made up at any time without heat The materials should be added sep arately and in the order named.
 By securing the materials in largo quantities the complete "soluble oil" may be made up for 16 to IS cents per gallon. If diluted with 15 parts water. as Is recommended the spray mixture costs slightly over one cent per gallon. The lime-sulphur wash l costs, including labor .and fuel. at 1 one and One-half cents per gallon and 1 the commercial soluble oil cost. de- pending upon the amount of dilution. from two and one-half to three and | cents per gallon.
 After a thorough stirring. take one part of the soluble oil'' to fifteen parts of water. Before mixing up large quantities. pour a few drops in } glass of water tO see if it mixes. If t has been properly made the mix ure will form milky emulsion with )ut any free oil on the surface. When that it will readily nix or 'emulsify" a convenient way is to 'our three gallons of the soluble oil nto fifty-gallOn spray barrel and hn he harrel with water.
 ThOroughness of application is of utmost importance. Badly infested fl should receive two appIica- ions. one in tho fall and the other n the early spring As a regular 'rartice. however. one application. ust after the leaves drop in the fall. hould keep tho insect Tn cheek. ( Where the leaf curl Is prevalent in : 'each orchard the oil spray in the all may he supplemented by q spring pplication of lime and sulphur. Ali Inet nOzZie should he u~ed fo. tbn il than for the line-suIphgr wash. ls n this way more thorough and more ] i cOnomical work may he done Re ause If It's grsater spreading action i nd of it's adaptability to a finer noz- $ le. one gallon of oil emulsion will go ( s far as one and one-half gallons of I ha lime-sulTihur wash. { Complete information Is given fin t7e { ulletin regarding the source and enxt { f materials. tho preparation of inc q soluble oiL@ the necessary 1r=cau- q ions snd the time and method of ap- T licati0u<- q The bu1letin win he sent free rroa ! c pquest ny addressing the Sfn-rz Fx- a eTiment Station.
