transplanted to the field ; or some of it may mature directly 

 in the hotbed or frame. In some cases, particularly for 

 the midseason and later crops, the seed may be sown where 

 the plants are to stand. In large-ai;ea lettuce-farming in 



the Northern States, prin- 

 cipally on reclaimed muck 

 land, seed is sown direct- 

 ly in the field and the 

 plants (if Big Boston) are 

 thinned to stand 10 to 14 

 inches in the row, the rows 

 14 inches or more apart. 

 Two or three pounds of 

 seed are required to the 

 acre. In good weather 

 and on well-prepared land, 

 the crop is ready to har- 

 vest in six to eight weeks. 

 Sowings are made every 

 week or so till the begin-

Lettuce may be fol- 

 lowed by cabbages, early cauliflower, celery or various 

 other succession-crops. Sometimes lettuce is transplanted 

 between the plants of early cabbages or cauliflowers, 

 since it will mature before the other plants need all the 

 space. If one's soil is moist, and particularly if the 

 exposure is somewhat cool, the ordinary spring lettuce 

 may be grown with success throughout the summer. Suc- 

 cessional sowings may be made as often as once in ten 

 days to three weeks. The earliest spring lettuce taken
