LETTUCE 
Lettuce does not stand hot weather well but 1s not harmed by mild frosts; the earliest 
sorts can therefore be transplanted from cold frames to the rows, after hardening by 
gradual exposure, in the fst weeks of spring and the later sorts sown 14" deep in 
the open then. Rich and well-prepared soil is advisable as the plants must be grown 
quickly. Moisture and thorough cultivation are also required. Allow Yg oz. per 100 ft. 
of row; 3 lb. per acre.
