On account of the small number of pears on these trees 

 the above result should be taken as an indication rather than 

 as conclusive evidence. 



In another orchard on the same dates as the above the 

 following sprayings were made : 



A. Three Sheldons unsprayed as checks. 



B. One Sheldon sprayed with Bordeaux mixture, containing one pound 

 each blue vitriol and lime to 12 gallons water. 



C. Two Sheldons, Bordeaux mixture 1-16. 



D. Two Sheldons, Modified Eau Celeste. 



E. Three Sheldons, Ammoniacal Solution Copper Carbonate. 



When gathered the following was found to be the result :

Four Lawrence pear trees were sprayed with Bordeaux 

 mixture, and one left unsprayed. The sprayings were 

 made May 20, June 10, 21, and July i. 



The pears when gathered showed the following :

These figures do not show the full effect of the spraying. 

 From the statements of the owner it was inferred that the 

 pears were subject to the attacks of some fungus disease, 

 but not being familiar with the Lawrence we did not know 

 just what one. The sequel showed that there were two, 

 one the ordinary Scab and a second fungus described on 

 page 9. While the pears from the unsprayed tree classed as 

 first quality were of good size and such as are frequently seen 

 in the market, the majority of them were more or less 

 badly disfigured by this fungus. On the unsprayed tree 88 

 per cent, of the pears were affected with it, while on the 

 sprayed trees less than i per cent, were affected. So far 

 as our observation goes the Scab does not seem to affect the
