100 REPORT OF THE BOTANICAL DEPARTMENT OF THE 
AS SHOWN BY THE YIELD. 
At Geneva.—The potatoes were dug by hand October 18 and 
19. At this time the plants on the unsprayed rows had been 
dead over a month and were thoroughly dry. Those on the 
sprayed rows had been killed by frost twelve days before and 
most of the stems were already dry. 
Some remarkable results being anticipated it was thought desir- 
able to have witnesses present at the digging. Mr. T. B. Wilson 
of Halls Corners, President of the New York State Fruit Grow- 
ers’ Association, was requested to name some one to act with 
him as a committee to witness the digging. Mr. Wilson kindly 
consented and named as the other member of the committee, 
Mr. C. K. Scoon, a fruit grower of Geneva. These two gentle- 
men met at the Station on the afternoon of October 18. Because 
of lack of time it was not feasible for them to remain until all 15 
rows were dug. Accordingly, three rows, Nos. 8, 9 and 10, 
about the middle of the field, were selected for the test. These 
rows they saw dug, weighed, and the length measured. As the 
tubers lay on the ground after digging they were photographed. 
(See Plate IV.) Plate III shows the same rows as they appeared 
on September 17. The yields are given in Table V. 
Throughout the experiment the product of each row was sorted 
into three grades—marketable, rotten and culls. All sound tub- 
ers larger than a hen’s egg were graded as marketable. The 
sorting was all done by the writers and as uniformly as possible.
