JOINED OR SEPARATE HOUSES. 



At the present time there is considerable controversy about the merits of joined 

 or separate houses. Growers in the east use separate houses almost entirely while 

 those around Chicago Jiave used ranges of joined houses. It appears on investiga- 

 tion that Avhere wide houses are being built, separate ones are used entirely. 



Joined and separate houses are often found in the same range. In such cases the 

 grower nearly always prefers the separate house and advocates this arrangement 

 only.
