materials directly from the large producers or distributers as 

 indicated in the following, except, of course, in a small way 

 for trial. If the local druggist is willing to assume the re- 

 sponsibility and if the materials are secured at a reasonable 

 price, it would certainly be advisable to patronize a local con- 

 cern. Materials are sometimes offered at a suspiciously low 

 price. A New Jersey fruit grower who recently inquired for 

 information with regard to materials, incidentally mentioned 

 the fact that he could secure liquid crude carbolic acid, 100%, 

 for 35 cents per gallon in small lots. He was promptly ad- 

 vised to secure his materials from another source, for the rea- 

 son that the largest producers of carbolic acid in America were 

 quoting liquid crude, 100%, at 52 cents per 'gallon by the bar- 

 rel. The standards for many materials used in the work are 

 based upon a specific gravity test, with which the average fruit 

 grower is unfamiliar. For this reason he must depend upon 

 the dealer to supply the proper materials. It is, therefore, 

 important that only responsible dealers are patronized. Un- 

 doubtedly several local concerns, especially those who cater to 

 the agricultural trade, will handle the proper materials when 

 thev come to know what is wanted, and to realize the demand 

 for such. The Sisson Drug Company, Hartford, Connecti- 

 cut, claims to have a complete stock of the proper materials for 

 the preparation of "soluble oil." 



For the benefit of those who require small quantities of 

 ''soluble oil," and for those who wish to avoid the trouble of 

 making it, arrangements have been made with the John T. 

 Robertson Company, Manchester, Connecticut, to make up 

 and offer for sale a soluble oil after the formula herewith pro- 

 posed. 



"Soluble oils'' are very easily adulterated or diluted. The 

 addition of water to a certain limit thickens the material and 

 gives the impression that it might be of better quality. The 

 dishonest agent may take advantage of this fact and lead the 

 purchaser to believe that he is selling a soluble oil of superior 

 quality. An adulteration of this kind, however, may usually 

 be detected by the muddy brownish appearance of the mixture. 



In order to secure materials at the lowest rate and to
