New York AGRICULTURAL EXPERIMENT STATION. 341 
bed was considered sufficient to produce the required number of sets 
for planting forty acres but only q little more than four acres were 
actually planted. 
Late seeding.—Additional beds were sown on May 17 and May 
28, but owing to the attacks of root-maggots and the lateness of the 
season, all of the plants that survived were undersized and none 
were transplanted. 
COST OF MATERIALS FOR FRAME AND SCREENING. 
The length of the seed-bed was 150 feet and the width was 12 
feet. The items of expense for materials for the frame and cover- 
ing are as follows :—

The number of seedlings transplanted from this bed was 50,000, 
which makes the first cost of the frame and screening approxi- 
mately about 40c. per 1,000 plants. Estimating that the screening 
could be used for three seasons, as is generally agreed, and that 
the boards could be used for this purpose for at least ten years, 
the cost of the materials for screening a bed, on the basis of these 
experiments, would be approximately 8 cents per thousand plants 
each year. The initial cost of the lumber could have been much re- 
duced by having the frame more nearly square, rather than oblong. 
OPINIONS OF FARMERS ON SCREENING CABBAGE 
SEED-BEDS. 
The screening of cabbage seed-beds for protection against mag- 
gots has not generally proven successful. However, a number of 
growers during the past season covered a portion of their beds in 
the manner described in the Station’s experiment and all have 
been well satisfied with the quantity and the growth of the seedlings 
in the screened frames. 
The opinions of a number of farmers, who have reported their 
results, are summed up as follows: The cost of boards is not en- 
tirely considered as an item of expense; for if it were necessary to 
purchase a new supply, the value of the lumber for other farm
