36 THE GRAPH. 



and if the heating apparatus be fixed around tho 

 inside, near to the walls, there will be an equal distribu- 

 tion over all parts. Such a house, if only ten feet wide, 

 would accommodate three rows of vines, and leave room, 

 for a pathway ; one row being placed near to the back 

 with the path next, and the other two nearer the front. 

 With this arrangement, there would be no occasion to 

 elevate the roof more than to give sufficient headway, as 

 the path would be directly under the ridge, say six feet 

 above ground, and seven feet from the inside level, by 

 which the exposure to cold, and severe winds is consider- 

 ably avoided, and a steady heat maintained with much 

 saving of fuel. There may be some objection to the short 

 back lights, which should be of glass, but as these may be 

 readily covered by shutters at night, and in severe dull 

 weather the evil is less than the common form of lean- 

 to, which has to be elevated according to the width of the 

 house, and inclination of the roof. It is only for pot cul- 

 ture that this will become serviceable in grape growing, 

 but for the purpose named, it is most suitable, can be 

 erected cheap, and is a compact and easily-managed struc- 

 ture. Where the house is already built, or it may be in- 

 convenient to adopt the above plan, on account of other- 

 wise general arrangement, an ordinary lean-to, and more 

 particularly the curve line will answer the purpose to 

 almost equal advantage, and the design is only given as 

 the best adapted, where the intention is to be as perfect 

 as possible. 



THE RETARDING HOUSE. As the object of the retard- 

 ing house is to have grapes beyond the time when the Cold 

 Grapery, or least forwarded house will furnish them, it 

 ought to be so situated as to assist in checking the early 

 growth of the vines, it is also desirable that it should be 

 capable of being rendered thoroughly dry inside, and like-
