up as follows : Nitrate of soda, 350 fbs. ; sulphate of ammonia, 

 150 fbs; sulphate of potash, 230 tbs ; acid phosphate, 220 lt)S. ; 

 kieserite, 50 lbs. Unquestionably this fertilizer produces a most 

 vigorous growth, resulting in large, though not always well 

 colored fruit, and on uncultivated land is regarded with favor 

 by many growers. 



The Station 'formula contains about 3% nitrogen, 5>^% 

 phosphoric acid, and 8 % of potash, being made up of 200 tbs. 

 nitrate of soda; 75 fbs. sulphate of ammonia; 225 tbs. muriate 

 of potash; 500 tbs. of acid rock — in each 1,000 tbs. The Fisher 

 formula costs about $21 per 1,000 tbs., or 21 cents per tree for 

 each application; the other $16 per 1,000 tbs., or 16 cents per 

 tree. 



Twenty Baldwins and five Talmans are being used for the 

 specific test of each of these formulas. The Baldwins are kept 

 under cultivation ; the Talmans are in sod. The work has been 

 in progress for two seasons, which time is of course not sufifi- 

 cient to warrant conclusions. Both lots of trees have responded 

 freely to the treatment, and yielded a good crop of fruit this 

 year. The Talmans also bore well last year, while the Baldwins 

 were in an exhausted condition when the work was commenced. 

 All are now making a remarkably strong vigorous growth, and 

 promise well. It should be said, however, that as in the experi- 

 ments first mentioned the stirring of the soil, and the decay of 

 the turf in case of the cultivated trees, obscure any specific 

 difference in the relative merits of the two formulas up to the 

 present time. 



Mr. MoRSiJ: I would like to have Prof. Munson explain a 

 little about the variation in these fertilizers. Some who have 

 been buying have got low grade material. 



Prof. Munson : I should say in all of these it pays to buy 

 the best grade of everything. In buying commercial fertilizers, 

 you cannot afford to pay freight on coal ashes and sand, and 

 that is what it amounts to when you buy low grade fertilizers. 

 I would simply say that in buying fertilizers of this kind, the 

 proper way to do is to make out a list of the amounts of material 

 that will be needed to cover the number of trees that you have 

 and send that list to the Bowker people or the Sagadahoc people 

 and get them to give an estimate as to what they will furnish the 

 material for, 'and specify that only high grade goods are to be 

 employed ; and then order it where you can get the best terms.
