Lettuce—Big Boston 
tndudd, Lettuce 
Lettuce has been cultivated in Hurope since 1562. 
The origin before that is unknown. One ounce of 
seed will plant 200 feet of row. Plant three pounds 
to the acre. Breaks ground in 8 days under fa- 
vorable conditions. To have outstanding Lettuce 
in early Spring, sow in seed bed the September 
preceding. Protect the plants during the Winter 
in a box covered with glass or litter. Early in the 
Spring transplant half into rich ground. The other 
half force to an earlier development under sash. 
For a later supply, sow in drills; when up a few 
inches, thin out plants 10 to 12 inches apart for 
heading varieties and 3 to 8 inches for loose- 
leaved. Plant seed very shallow. Use plenty of 
water, thoroughly cultivate and if possible shade 
lettuce in the hottest weather.
