REMARKS ON THE DIMENSIONS, ETC., SUITABLE FOR ORCHARD- 

 HOUSES. 



Although a number of tliese interesting structures are now 

 in full work, and are becoming more known daily, as may be 

 seen from the number of inquiries made respecting my own, 

 and those of others, perhaps a few remarks on their dimen- 

 sions and form may not be out of place. A lean-to orchard- 

 house, thirty feet long, should be thirteen feet wide. If the 

 back wall be twelve feet high, that is ample ; and the front 

 should be about four or five feet high, but not more. Shutters 

 from twelve to fifteen inches in width all along the front, 

 which is conveniently made of half-inch boards, and about 

 half of the same quantity of ventilation at the back, are 

 required. Glass ventilators, swinging on pivots, instead of 

 wooden ones, are more expensive, but where this is of no 

 consequence, much preferable. Such a house need not cost 

 thirty pounds. 



A lean-to house, 100 feet long or more, with walls fifteen 

 feet high, and eighteen or twenty feet wide, would be mag- 

 nificent, and have a double walk — one near the wall trees, 

 and one near the front row. In the smaller lean-to, which is 

 only thirteen feet wide, one walk only is permissible, and that 

 may be where you please ; but near the wall trees is best, as 

 it gives more head-room, and enables you to attend to the 

 wall trees better. To do this, a small ladder six feet high, 

 and exactly twelve inches in breadth, (in order to slip between 

 the spurs,) is requisite. 



A small span-roofed house should be fourteen feet wide, 

 five feet high at the sides, and nine feet high to the ridge. 

 One centre walk leads between two rows of potted trees on 

 either hand, the smaller trees, of course, nearest to tlie sides. 



A house thirty feet by fourteen costs about thirty pounds. 

 Larger houses are twenty feet wide, sides about five feet high, 

 height to the ridge about ten feet; the paths, two in number,
