LETTUCE 
Lettuce does not stand hot weather well but is 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 first weeks of spring and the later sorts sown V4 deep in 
the open then. Rich and well-prepared soil is advisable as the plants must be grown 
quickly. Motsture and thorough cultivation are also required. Allow V% oz. per 100 ft. 
of row; 3 lb. per acre.
