Experiments conducted last year. 



It was in consideration of the above results that a series of experi- 

 ments along this line Avere conducted at Abbotsford, Que., durinj^ 

 the past season, on the farm of \Vm. Craig & Son. I am indebted 

 to Mr. Wm. Craig, jr., for his labour in superintending the work> 

 and furnishing me with some of the facts upon which the following 

 deductions are based. 



I am also indebted to Mr. F, T. Shutt, Chemist to the Experi- 

 mental Farms, for valuable assistance in planning the lines of 

 experiments, and for the preparation of the copper carbonate and 

 other necessary materials. 



The trees selected were of the Fameuse veriety, planted fourteen 

 years ago on a loose, gravelly soil. During the past four years this 

 orchard has not yielded more than 25, and often not even 10 per 

 cent, of first-class apples. 



Five rows in the centre of this orchard were selected, each row, 

 which contained fourteen trees, being treated with a different mix- 

 ture. A row of trees untreated was allowed to remain on either 

 side of those operated upon. Four applications were made, one on 

 each of the following dates : 14th and 26th June, and 17th and 29th 

 July. At the time of the first application the fruit was about the 

 size of garden peas. 



When the fruit was picked it was divided into three grades, num- 

 bered, according to quality, first, second and third. The results are 

 given in this way : — 



Row 1. — Treated with 



Copper carbonate 1^ oz. 



Ammonia 1 qt. 



Water 22 gals. 



Result: 



Per cent. 



First quality 33 



Second do 25 



Third do 42 



Row 2.— Treated with 



Copper carbonate 3 oz. 



Water 22 gals
