present in varying numbers. The remaining 38 per cent, which we 

 find to be divided between lime-sulphur and oil users, in the propor- 

 tion of two to three failed to report on this point, owing to difficulty 

 in deciding on percentages. A fairly definite idea of conditions 

 may perhaps be given by referring to a statement made by an apple 

 buyer who has had a good opportunity to size up the general situa- 

 tion during several years. He says that so far as fruit is concerned, 

 the Association members seem to have the situation well in hand 

 as their 190S crop was less spotted than in previous years. 



We have prepared, from figures submitted, the following table 

 of comparative cost of making 100 gallons dilute spray as between 

 lime-sulphur solution and oil preparations. In this estimate the 

 lime-sulphur solution was made from 40 pounds of lime and 30 

 pounds of sulphur, boiled for one hour and diluted to 100 gallons 

 compared with which the oil figures are based on a proportion of 

 one to twenty.

A further examination of the report shows that 60 per cent, used 

 power sprayers, the remaining 40 per cent, having hand pumps and 

 that the comparative cost of applying 100 gallons was as follows:
