double-planked, and the space between filled with closely rammed 

 dry tar. The sashes for the roof should be of two lengths, lapping 

 slightly at the middle, and sliding past each other in separate 

 grooves. 



CURVILINEAR ROOFS FOR GRAPERIES. This is a form often given 

 to the more highly finished class of grape-houses. It possesses 

 some advantages, and when neatly constructed, presents a handsome 

 appearance. But there is another form originated and adopted some 

 years ago by Ellwanger & Barry of Rochester, which is shown in 

 the annexed figure (Fig. 438), and which appears to be a decided

improvement. The base walls, on which the frame rests, are per- 

 pendicular ; and the lower part only of the frame is curved. This 

 form gives it a neater and less heavy appearance, and is more easily 

 and cheaply constructed. It is occupied as a cold grapery, and is 

 seventy feet long, fourteen feet high, and sixteen feet wide. 



BORDER FOR THE VINES. This should never be less than twelve 

 feet wide, and if twenty or twenty-five feet, it would be better. The 

 roots of grape vines run rapidly to a great distance, and it is indis- 

 pensable to their successful growth to furnish them ample room for 

 extension. J. F. Allen, of Salem, Mass., in his Treatise on the 

 Grape, recommends for a border, a mixture of one-half loam, or the 

 top soil of an old pasture, one-fourth bones or other strong manure, 

 one-eighth oyster shells, lime, or brick rubbish, one-eighth rotten 

 stable manure varying with circumstances. The bed should be 

 well mixed, and should be two to three feet deep.
