LETTirCE. 161 



WTien Lettuce is set out in a bed by itself, the 

 plants may be put fifteen inches apart each way. 

 Like most other garden prodiicts, it needs, in order to 

 insure success, a deep, rich soil that is kept well cul- 

 tivated. 



Growing Lettuce in Winter, by bottom-heat, both 

 in hot-beds and in forcing-pits, is a large and lucra- 

 tive branch of the market-gardener's business, when 

 situated near large cities. Formerly a large part of 

 the frame Lettuce was grown in cold-beds ; planted 

 in November (fifty plants to a sash), the crop would 

 be ready for market early in May. This system 

 has given way, in turn, to hot-beds and, more recent- 

 ly, to forcing-houses, put up expressly for growing 

 vegetables (especially Lettuce) during the Winter 

 months. There have been a dozen or more of this 

 kind of house put up in the vicinity of Newark, N. 

 J., last year, and as many more will be built the 

 present season. Considering the economy of time 

 in managing these forcing-houses, they will, without 

 doubt, entirely supersede the old style hot-bed sys- 

 tem. 



Under the headings "Hot-Beds" and "Forcing- 

 Houses," there will be found fuller directions about 

 their care, construction, &c., &c. 



Although there is a long list of varieties of Let- 

 tuce given in seedsmen's catalogues, only a few of 

 them will pay to grow either for family use or mar- 

 ket. Among the best for either purpose may be 

 named 



Eaelt Ctjeled Simpson. — This is one of the best
