ORCHARD HOUSES. 295 



of a grapery, except that it should be higher at the sides, 

 with the roof more flattened, in order that the trees may 

 be brought as near the glass as possible. Ventilation is 

 an important item, as too groat heat, or a confined atmos- 

 phere, are incompatible with success. A span-roof house 

 should have ventilators all along the bottom and top, and 

 lean-to houses require even more openings than span-roofs. 



Mr. Rivers, of England, who first set in motion the art 

 of fruiting trees in the house, built his first houses like 

 sheds, or what is termed lean-to, and. so far the most of 

 the structures erected in this country for this purpose 

 have been of that style. The house of Mr. Pullen, in 

 New Jersey, which has proved a commercial success, is 

 fourteen feet wide and one hun- 

 dred feet long. The house of 

 Mr. Lovering is the same width, 

 with the back wall twelve feet 

 and the front wall four feet 

 high. Fig. 145 is an end view, 

 taken from Dr. Norris' work on 

 " Fruit Trees in Pots," in which 

 the interior arrangement is 

 given as follows: "The fruit 

 border (three feet six inches 

 wide) is raised nine incl.es above rlg ' 145 - E VIEW OTHOCSE ' 

 the walk (which is two feet six inches wide) ; the first 

 back border is three feet wide and raised sixteen inches 

 above the walk. The second back border is raised one 

 foot above the front one and is four feet wide." 



In " Peach Culture," by J. A. Fulton, a lean-to house, 

 twelve feet wide by fifty feet long, is described, with the 

 back wall fourteen feet high and the front four feet (see 

 fig. 146). In this house it will be seen that the lower range 

 of sash is hung on hinges to a plate securing the lower 

 ends of the upper sash, and no other ventilation is sup- 

 plied, except by the opening of doors. It is designed, in
