and spread over the entire area of the Ladd orchard. A large per 

 cent, of the fallen leaves were destro} T ed and it was expected that 

 the amount of scab would be thus reduced. The effect was 

 apparently greater than was anticipated as not a scab spot developed 

 on the foliage or fruit in this orchard the following summer, while 

 the checks in the Smith orchard had 14 per cent, of the fruit scabbed 

 and an adjacent Mcintosh orchard was badly affected with scab. 

 The scab record as given below for the Smith orchard was based on 

 a count of the total dropped and picked fruit. The record on spray 

 injury was obtained in the Smith orchard by a careful estimate and 

 in the Ladd orchard by an actual count of 500 or more leaves from 

 each plot. Both orchards were practically free from leaf spot. 

 Plots 1 to 10 inclusive were in the Ladd orchard, plots 11 to 17 

 inclusive in the Smith orchard.
