Comparing the sprayed with the unsprayed trees it will be seen 
that there were no fruits and 45.4 per ct. of a crop of leaves upon 
trees treated with the boiled lime-sulphur-salt wash; 47.8 per 
ct. of a crop of fruit and 46.9 per ct. of a crop of leaves upon 
trees treated with the lime-sulphur wash; no fruits and 41.2 per 
ct. of a crop of leaves upon trees treated with the self-boiled 
lime-sulphur-caustic soda wash; and 1.2 per ct. of a crop of fruit 
and 40.5 per ct. of a crop of leaves upon the trees treated with 
the boiled lime-sulphur-caustie soda wash.
