very necessary. The apples on the table there indicate very well the 

 average run of the fruit on the checks, the Bordeaux sprayed and 

 the Lime Sulphur sprayed trees. Careful counts of all the apples on all 

 the trees in the experiment showed at picking time that 42 per cent of 

 the apples on the check trees were scabbed (See Fig. i), on the Bor- 

 deaux trees this was reduced to 3 per cent, and on the Lime Sulphur

trees t-o 3.6 per cent. The Lime Sulphur was practically as effective 

 in preventing the scab as was the Bordeaux. However, 82 per cent, 

 of the apples on the trees sprayed with Bordeaux were russeted, i. e., 

 injured by the mixture, and to so severe an extent as to much re- 

 duce their market value (See Fig. 2). The apples sprayed with the 

 Lime Sulphur showed less than 4 per cent of russeting of any kind, 

 in striking contrast not only to the Bordeaux injured fruit, but also

to the apples from the check trees, which showed 29 per cent of 

 russeting, due perhaps to certain weather conditions. Why the Lime 

 Sulphur sprayed fruit should have been so free from this natural 

 russeting is not clear. No injury of any kind either to fruit or foliage 

 resulted from the applications of the Lime Sulphur at the dilution of 

 I to 30 (See Fig. 3). The experiments showed that no addition of
