CuLture.—Lettuce requires a very rich soil and the 
best care the skilful cultivator can give, in order to obtain 
that crispness, juiciness and delicate flavor. In sowing 
seed during the dry, hot weather the ground should be 
kept moist and shaded, as the sun will burn the germinating 
power out of the seed.
