The average number of all well-developed buds on the spraj^ed trees was per linear inch of old wood, and on the unsprayed trees per inch of old wood. This shows a gain of 35 per cent in well-developed fruit buds in favor of the sprayed trees. These facts are shown in tabular form as follows: Table 19.—Gain in spur buds and other well-developed fndt buds on sprayed over unsprayed trees. Records. Trees. Sprayed. Unsprayed.
