Imperial Iceberg No. 847 
LETTUCE 
1 ounce to 2,500 plants; 3 pounds per acre. 
Lettuce to be at its best should be grown rapidly, hence 
the soil should be made as rich and friable as possible by 
liberal manuring and thorough preparation. For early crop 
sow in a seed-bed in September or October and protect 
through the winter with cold frames, which should be re- 
moved as soon as danger of severe freezing is past. Lettuce 
in the open ground will stand some freezing but is killed by 
prolonged frost or frequent freezing and thawing. The seed 
may also be sown in hotbeds in March, and the plants, if 
well hardened, may usually be set in the open ground in 
April, maturing a crop much earlier than complete open 
ground cultivation would produce. If, however, it is not 
convenient to get the plants started either in the fall or 
early spring in hotbeds, the seed may be sown in open ground 
from the middle of April until July, selecting varieties suit- 
able for the season. 
The plants should stand 8 to 10 inches apart in the rows, 
and the rows should be about 18 inches apart. 
As a lettuce for greenhouse forcing 
Grand Rapids this variety undoubtedly stands at 
the head of the list, being of quick growth, hardy, little 
liable to rot and remaining in condition several days after 
being fit to cut. Forms a loose cluster of large, thin, bright 
green leaves, savoyed, finely crimped at edges. Will stand 
shipping long distances.
