flowers or tassels, before the ears are formed; this first brood did but 
very slight damage the past season, but the second brood was very 
destructive. The eggs of the second brood were laid upon the ends 
of the husks or on the silk, the worms attacking the ears, often 
cutting several grooves the whole length of the ear, thus rendering 
it unfit for use; they by no means confine themselves to a single 
ear, during their work of destruction, but go from one to another. 
As yet no very effective means have been discovered by which we 
can combat the boll worm ; having so many food plants it is hard 
to exterminate them. For some sections of the country, plowing 
fields deep in December and January is recommended, as by turn¬ 
ing up the soil at that season many of the early moths will be killed; 
hand-picking may be practiced where the area is small, as in family 
gardens, but it is a slow means of getting rid of them, and would be 
too expensive in large fields ; building fires in the fields in early 
. spring will attract many of the early moths, and thus destroy them. 
For this latitude, from the 15th to the 20th of May is early 
enough to make the first planting. By making a succession of 
plantings of the early, medium, and late sorts, at intervals of about 
ten days or tw^o weeks, it may be had in the green state until frost. 
Corn matures more quickly on a sandy loam, but attains a larger 
size when grown on clay or bottom land; the soil can not be too 
rich for it. 
On May 15th, four varieties of sweet corn were planted in rows 
3x3 feet, there being 150 hills of each kind. The ground was cul¬ 
tivated at frequent intervals until the corn was in bloom, after 
which the ground was not disturbed; water was applied on June 
21st and July 8th and 22nd. The first marketable ears pulled were 
of the Cory Early variety on August 2nd, 77 days from time of 
planting. 
Cory Early. —The earliest variety under test, stalks to 5 feet 
high ; ears 7 to 8 inches long; mostly eight-rowed, kernels flat, large, 
creamy white; marketable maturity, August 2nd. This variety 
ranks second in number of ears produced. Ninety-five per cent, of 
the ears were injured by worms. 
Early Minnesota. —The second variety to mature ; stalks 5 J to 6 
feet high, ears 8 to 9 inches long, 8 to 10-rowed, mostly eight, rows 
close; kernels large, whiter than those of Cory Early. MarketabE 
size August 11th, ranking first in number of ears produced; 92J 
per cent, of the ears injured by worms. 
Crosby’s Early. —Third in time of marketable maturity; stalks 
to 7J feet high, ears 7 to 8 inches long, 12 to 14-rowed, rows 
close; kernels small to medium, roundish, white; marketable size 
August 16th, ranking third in number of ears produced; 95J- per 
cent, of ears injured by worms.
