76 Report oF THE BOTANIST OF THE 
(7) Notes on expermment at Greenlawn.— The experiment 
field was situated on the farm of David R. Smith. It was trian- 
gular in shape and contained nearly one and one-half acres. For 
a time the stand was perfect and the plants healthy, but later in 
the season the bacterial or wilt disease caused some unevenness. 
This is shown in. the photograph of the field (Plate XV). After 
September 13 the yield was light and the pickles had a tendency 
to be “nubby.” This was apparently due to exhaustion of the 
vines and dry weather. There was very little downy mildew. 
On September 29 the owner pulled the vines in order to prepare 
the land for winter wheat. The vines were at that time still 
green, free from disease and bearing a few pickles. A few 
“withy” pickles were found where the vines were injured by the 
wilt disease, but no gummy pickles were found during the entire 
season. 
THE EXPERIMENT AT DEER PARK. 
(1) Preparation and planting.—The field, which contained 
two acres, was plowed once, then thirty-one tons of well rotted 
stable manure applied broadcast, after which the field was plowed 
twice more, each plowing being from five to six inches deep. The 
ground was thoroughly harrowed just before planting. 
At the time of planting 400 pounds of fertilizer were applied 
in the hills. The seed’® (Early Prolific) was planted July 1 in 
level hills four feet apart in the row, the rows being four feet six 
inches apart. 
(2) Cultivation and spraying.—The field was cultivated with 
a cultivator, three times each way, and hoed once around the 
hills. ‘The vines were sprayed eight times with Bordeaux mix- 
ture on the following dates: July 22 and 29; August 8, 17 and 22; 
and September 1, 9 and 19. 

16 The seed was purchased in Iowa for Early Prolific, but on account of the 
rank growth of vines and large size of the fruits the owner is of the opinion 
that the seed was not true to name and that the variety was in reality Long 
Green, or some similar variety. It is possible, however, that the rank growth 
of vines and fruit was due to an excess of fertility.
