As heretofore related, an accident to the spray pump prevented further spray- 

 ings after the middle of August, and how rapidly blight attacked the vines pre- 

 viously protected will be seen from observations taken August 25, or 12 days after 

 the last spraying had been given:

In the following table giving the results obtained, the time is given when the 

 plants were sufficiently above ground to distinguish the rows. The frost of June 

 5 blackened the tops of the fall planted rows, though a new growth had started 

 June 8. As will be noted, 18 to 39 days elapsed between planting time of the 

 spring planted and the date when the rows were distinguishable. The earliest 

 variety (Pingree) planted close by and on May 30, was up June 14:
