of yield. Hence the results as shown should represent approxi- 
mately what can be done by spraying under favorable conditions. 
The fact that the area used as a basis was small, allowing fac- 
tors of error to be exaggerated, lessens the value of the results 
as a whole, therefore conclusions as to the value of spraying 
should not be based upon these alone. | 
EXPERIMENT ON LONG ISLAND, 1899-1900. 
As the field, a portion of which was sprayed in the fall of 
1898, was not uniform in growth in all its parts, another field 
containing 15 rows, 408 feet long, set 6 feet apart, was selected. 
“he conditions and treatment of this field are as follows: The 
field contains thirteen rows of Columbian White and two rows 
of Conover’s Colossal, the whole having been set the spring of 
1893. A new bed of Palmetto joins it on the north. The field is — 
on the terminal moraine, the soil being a sandy loam. High 
grade fertilizers have been applied each year at a rate varying 
between 1500 and 2000 Ibs. Some seasons the whole of the 
fertilizer was applied early in the spring after which the field 
was either plowed shallow or gone over with the disc harrow. 
Generally the last week in April two furrows are thrown to the 
rows after which the “ridger” is started and run every Satur- 
day throughout the cutting season. Before each ridging the 
cultivator is usually run between the rows to loosen the soil. 
At the close of the cutting season, usually July 1, the ridges are 
plowed down and if all the fertilizer was not applied in the 
spring the remainder is put on after “ plowing down.” During 
the summer and fall growing season the field is cultivated every 
week or two until the ground is covered by the growth of aspara- 
gus tops. Usually the old tops are not removed until the fol- 
lowing spring. ; | 
The plan followed was: First, to determine the yielding capa- 
city of each row of the entire field previous to spraying, by 
weighing each cutting; second, to spray the growth on each 
alternate row during the fall; and third, during the next season, 
to weigh each cutting from each row as in the previous spring.
