From the foregoing table there are several facts readily seen. 
(a) The trees treated with Bordeaux mixture gave 18.6 per cent more 
fruit free from spot than the adjoining untreated tree, and 42.9 per cent 
more than the average of eighteen untreated trees. 
(b) Trees treated with copper acetate, 1:1000, gave 28.2 per cent more 
fruit free from spot than the adjoining untreated tree rs 40.5 per cent 
more than the average of eighteen untreated trees. 
(c) Trees treated with copper acetate, 1:505, gave 33.4 per cent more 
fruit free from spot than the adjoining untreated tree and 44.9 per cent 
more than the average of eighteen untreated trees. : 
(d) Trees treated with chloride of lime, 1:1000, gave 20.6 per cent less 
fruit free from spot than the adjoining untreated tree and 9.1 per cent 
less than the average of eighteen untreated trees. 
(e) Trees treated with chloride of lime, 1:505, gave 26.1 per cent less 
fruit free from spot than the adjoining untreated tree and 24.6 per cent 
less than the average of eighteen untreated trees. 
(f) Trees treated with chloride of lime, 1:540, gave 58 per cent Jess 
fruit free from spot than the adjoining untreated tree and 36.5 per cent -
