New YorK AGRICULTURAL EXPERIMENT STATION. De 
DETAILS OF THE TEN-YEAR EXPERIMENTS IN 1908. 
AT’ GENEVA. 
In 1908, the experiment was carried out in very nearly the 
Same manner as in previous years. As usual, there were 15 
rows 290.4 feet long by three feet wide. Planting was done 
by hand May 25. The variety was Rural New Yorker No. 2. 
The plat of land used was the same as that used for the ex- 
periment in ‘1903 and 1905. The soil was heavy clay loam 
and the previous crop alfalfa. 
The five rows constituting Series I were sprayed three times 
—twice with bordeaux mixture and paris green and once with 
bordeaux alone—the dates being July 38, 17 and Aug. 38. 
The five rows constituting Series II were sprayed six times 
—twice with bordeaux mixture and paris green and four times 
with bordeaux alone—the dates being July 3, 17, Aug. 3, 18, 
Sept. 1 and 16. | 
The five rows constituting Series III (Check) were not 
sprayed at all with bordeaux, but were treated twice (July 3 
and 20) with paris green in lime water to control bugs. 
The spraying was done very thoroughly with a knapsack 
sprayer. The bordeaux mixture used contained six pounds of 
copper sulphate to each 50 gallons and lime considerably in 
excess of the amount required to satisfy the potassium ferro- 
cyanide test. Whenever paris green was used it was applied 
at the rate of one pound to 50 gallons. 
It was the intention to apply poison to the unsprayed rows 
on the same date that Series I and II were sprayed the second 
time (July 17); but rain interfered, making it impossible to 
treat the unsprayed rows until July 20. During this period 
bugs were active and the unsprayed rows were slightly injured 
by them. After July 20 there was no further trouble with 
bugs. There was no early blight and no late blight. Flea 
beetles caused a little damage to the unsprayed rows, most of 
wuich occurred after September 1. The chief trouble was tip 
barn, which was quite severe. As late as September 1 the
