houses run north and south, they should be even-span or 

 of the ridge-and-furrow types. 



In locating houses which run east and west, it 'is con- 

 sidered preferable to place them a few degrees south of 

 west. In this way, the maximum number of sun's rays 

 are caught during the morning when most intense light 

 conditions are needed. Every possible means should 

 be taken to eliminate factors which may cause a loss of 

 light during the morning or the late afternoon hours. For 

 this reason, it is important that partitions be eliminated 

 as far as possible, for they diminish the intensity of light 

 conditions on either side of them during the morning 

 and afternoon. 



ACCESSORY BUILDINGS 



In connection with greenhouses, there are boiler rooms, 

 storage houses, potting and soil rooms, shipping rooms 

 with cold storage sections adjoining, and rooms for bulb 

 storage. If the range be a large one, there is usually a 

 carpenter's shop and an iron-working shop. Large growers 

 manufacture their boxes for shipping, their flats and other 

 smaller wooden materials used about the range, and they 

 also do their own construction work. Wagons and many 

 implements and tools used about the range are home- 

 made. This necessitates a staff of carpenters and painters. 

 Large ranges also have iron-working rooms with forges and 

 other equipment, where boiler repairs are made, and where 

 heating pipes, pipe supports for interior construction and 

 other iron work in connection with the building and general 

 up-keep of the range, is done. In large rose ranges, the 

 manure tank, which is usually separated somewhat from 

 other rooms, is an important factor in equipment. 



All of these buildings and rooms should be arranged so
