SEVENTEENTH ANNUAL MEETING. 91 



reduce transportation charges, fruit growers would do well 

 to combine orders. If such arrangements cannot be conven- 

 iently made, it will pay the average fruit grower to order his 

 materials in barrel lots, and carry them over from one season 

 to another. In view of the wide fluctuation in the price of 

 these materials it may often prove profitable to purchase a 

 large supply while prices are low. In tight barrels there would 

 be practically no shrinkage. 



Carbolic Acid. 

 Crude carbolic acid is sold at various strengths, ranging 

 from 20 to 100 per cent. Local dealers seldom carry the high- 

 er grade, for the lower grades usually satisfy the demand. 

 None but the 100 per cent, grade is suitable for our purpose. 

 This grade comes in two colors, designated as "straw color" 

 and "dark." The latter is usually about four cents per gallon 

 cheaper and apparently suits our purpose as well. Orders for 

 carbolic acid, then, should distinctly call for "liquid, crude 

 100%, dark." The Barrett Mfg. Co., Frankford, Philadelphia, 

 Pa., quotes this grade at 52 cents per gallon, by the barrel. 

 The prices fluctuate considerably, and at the present time are 

 very high. 



Fish Oil. 

 Any pure fish oil will answer our purpose, but that known 

 as Menhaden oil is much cheaper in this section of the coun- 

 try. The cheaper grades used by the veterinarian will not 

 saponify, and are, therefore, unsuited to our purpose. Fish 

 oil adulterated with mineral oils is often found in commerce 

 and is also unsuited to our purpose. The oil at the bottom 

 of a can or a barrel is often very thick and granular. This 

 is somewhat inconvenient to handle, but works almost as well 

 as the liquid portion. The firm of Harden, Orth and Hast- 

 ings, 225 Purchase Street, Boston, Mass., is one of the largest 

 and most reliable producers of fish oil in this section. Messrs. 

 Heller, Hirsch & Co.. 62-64 William Street, New York, pro- 

 duce fish oil of good quality. The prevailing price is about 

 37 cents per gallon by the barrel, and 40 cents in smaller lots.
