THE CULTURE OF THE GRAPE. 25 



building on the rear -would add from one to two dollars per 

 foot to the cost, accordhig to the kind of room or wall con- 

 structed. 



The following is an account of the cost of a small graperj, 

 on all sides of glass, with a brick foundation, furnished me by 

 a gentleman of Salem : — 



" All the space which could be spared for the purpose was 

 seventeen square feet. The house is seventeen feet in length 

 bj nine feet in width. The brick foundation is eight inches 

 thick, and two feet high, (with four hanging windows in front, 

 of three panes each, seven by nine glass,) on which is placed 

 a sill six inches deep. There are five rafters, with a corre- 

 sponding number of posts on the back of the house, framed 

 into a plate at the top. The inclined sashes are permanent ; 

 the angle of inclination 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 inches deep. 



" There are five front vines, which are planted on the out- 

 side ; four back vines in the alternate spaces, and one vine at 

 each end, are planted on the inside. The entrance is at the 

 end of the house by a porch projecting three feet, and con- 

 taining an inner lattice door for ventilation. 



" The house would be more airy, and better in every 

 respect, if twelve feet in width. The border also, if possible, 

 should have been twelve or fifteen feet wide, which would 

 obviate the necessity of an annual manuring with guano, in 

 order to carry oflf the crop well. 



" One hundred and twenty-five pounds of well-ripened 

 gi'apes can be safely calculated upon from such a house as 

 the above, as a permanent annual crop ; say five front vines 

 at fifteen pounds each, seven back and end vines at seven 

 pounds each. With a wider border, the front vines would 

 ripen equally well twenty pounds each. 



" Cost of the whole, including vines, preparation of border,
