HILLSIDE LOCATION. 97 



essential. It is a common observation that a protected hill- 

 side, sloping south, is an entirely different climate from the 

 north side of the hill. We have all seen protected nooks, 

 looking towards the sun, which smile as with the touch of 

 spring, even in midwinter. No amount of coal can be an 

 equivalent for the life-giving warmth of the sun. 



I have constructed a form of houses, which may be called 

 the hillside or terrace style, which I regard as admirably 

 adapted for such positions. Indeed, I consider the advantages 

 of the position, combined with the economy of construction 

 and management of the houses, to be so decided, that I believe 

 they will come into general use for winter-gardening. In 

 order that the plan may be more clearly understood, and in 

 the hope that others may be induced to give it a trial, I will 

 give a somewhat full description, which was prepared for the 

 Philadelphia " Gardener's Monthly," and published in the 

 August number for 1874. 



The site must be a southern hillside, sloping at an angle of 

 from eighteen to twenty-five degrees. Having graded the lot 

 off — say one hundred feet square — then build a stone wall on 

 the four sides, averaging about five feet high. The outer sides 

 of the wall are to be banked up level with the top, with the 

 earth taken out of the sunken walks or elsewhere. The 

 inside is to be pointed with mortar. We now have a sunken 

 pit — one hundred feet square — to be covered with glass. A 

 diagram will best illustrate the form. It consists of a sue- 

 cession of lean-to sections, ten, twelve or fifteen feet in width, 

 as may seem most desirable for the work intended. The roof 

 is supported by the upper and lower wall, and also by the 

 rows of posts, a a a, six feet apart, which run under the 

 gutters. The ventilators, d (I, are of wood, and serve as an 

 effectual guard against a heavy fall of snow. In case it were 

 ever found necessary to remove snow, a sled, with one narrow 

 runner to rest upon the ventilator, would be serviceable. But 

 I have found no occasion to use my sled. 



As illustrating the simplicity of the parts, which may all be 

 made by machinery, I give a diagram of the parts for one of 

 my houses, which is in sections, ten and a half feet wide. 

 The sash-bar of spruce, two by two, is nine and a half feet long. 

 The rabbet for the glass is deeper than usual, and is shown
