The area planted to grapes on this farm consists of two rectangular sections lying parallel but separated for an interval of slightly more than 200 yards by land given to general crops. The soil is Dunkirk silty clay loam1 and the surface is practically level. There is considerable variation in age and vigor of the vines. However four sections were selected, in each of which the vines were apparently uniform as regards age, vigor and infestation. Owing to the variations between sections it is unsafe to compare one with the other, except that differences may be averaged as is done in the summary of results. The field trials were to determine the values of (1) bordeaux mixture and arsenate of lead and (2) arsenate of lead and glucose for the control of the grape root-worm.
