THE CULTURE OF THE GRAPE S5 



are five rafters, with a corresponding number of posts on 

 the back of the house, framed into a plate at the top. 

 The inclined sashes are permanent ; the angle of inclina- 

 tion is fifty degrees. The vertical sashes on the back 

 side are nine feet in length. The ventilation is from the 

 back, the ends and the front. 



"The border is eight feet wide, well-elevated, fifteen 

 inches deep exclusive of a substratum of bones, nine
