8 FRUIT TKEES IN POTS [ch.

 than the one previously described. 



The dimensions of the house will be as follows : 

 width, 24. ft. ; height at apex, 12 ft. ; height at 

 eaves, 5 ft. 6 ins. ; length, from 50 to 100 or more 

 ft. ; but where space and means permit, I strongly 

 recommend 100 ft. 



For side supports of this house, I should advise 

 the use of " oak posts " as principal posts, and these 

 should be 5 or 6 ft. apart. They should be sunk 

 in the ground to a sufficient depth to make them 

 quite firm and safe for the rafters to rest upon. 

 Some people adopt the plan of inserting posts in 

 " iron sockets," others prefer to tar them, while 

 some think it better to char them. The posts 

 should be about 6 ins. wide and 4 ins. thick, and 

 each interval, i.e. from post to post, should be 

 bricked in (4|-in. work above ground) to a suffi- 

 cient height to allow for sill, ventilators, and glass 

 above, to the eave plate. (See plan of 18 ft. wide 

 house. ) 



It will be noticed in the plan that there are two 

 courses of 9 -in. work above ground, but in the large 

 house this will not be necessary, as the oak posts 

 will be sunk in the ground instead of resting on 

 the sill, as in 18 ft. wide house. 



The use of a sill will be of great advantage 

 in the intervals between the oak posts, and if
