GREENHOUSES FOR FORCING VEGETABLES. 



CHAPTER X. 



WIDE GREENHOUSES FOR 

 FORCING VEGETABLE CROPS. 

 Since " Gardening for Profit " 

 was first written, larger experi- 

 ence has shown that greenhouse 

 structures for forcing vegetables 

 cannot only be erected cheaper 

 when made twenty or twenty- 

 two feet wide, instead of ten or 

 eleven feet as then in use, but 

 from the larger volume of air 

 they contain, which when once 

 heated better resists the cold 

 outer air, less artificial heat is 

 necessary. So well convinced 

 were we of the advantages of 

 the wider structure, that six 

 years a^o we removed all our 

 old eleven foot houses (covering 

 nearly an acre in glass) and re- 

 placed them with greenhouses 

 averaging twenty feet wide by 

 100 feet in length. John Hud- 

 son, of Jersey City, New Jersey, 

 one of the most successful of all 

 our market gardeners in the 

 vicinity of New York, con- 

 structed, the past season, six 

 greenhouses, each 150 feet long 

 by twenty-two feet wide, plans 

 of which are given in figures 9 

 and 10. The cost of these 

 greenhouses complete, with ven- 

 tilating apparatus, heating, 

 benches, etc., was about $10,000,
