THE CULTURE OF THE GBAPE. 91 



tho roots have so extended themselves, that they will 

 suffer for the want of farther protectioa. 



Where grapes are grown under glass on an extensive 

 scale, it would be diflScult to obtain fresh stable manure 

 in sufBcient quantities (in most parts of our country it 

 would be impossible,) to make it practicable, and the 

 expense of so doing would be more than the value of the 

 crop would warrant. In the vicinity of large cities, and 

 occasionally in other localities, this manure may be ob- 

 tained cheaply, and in sufBcient quantities for the pur- 

 pose ; where this is the case, the objection to it, on the 

 score of expense, is obviated. 



A grapery one hundred feet long would require a 

 border one hundred and ten feet in length and twenty- 

 four feet wide. As, by Mr. Eoberts's plan, the border is 

 to be covered with this heating manure and leaves ybwr" 

 feet leyo7id where the roots of the vine extend, and two 

 and a half feet deep, in a few years, or as soon as tlie 

 vines have become established, it follows, that the enor- 

 mous quantity of 65-nnr cords of manure would be re- 

 quired, to cover in this manner, the border where the 

 roots are now presumed to have extended themselves ; 

 thus, one hundred and twenty feet long, twenty-eight feet 

 wide, and two and a half feet deep. 



In our cold winter, I found it necessary to renew the 

 heat by adding one fourth part of the new manure, and 

 working it in with the old, every three or four weeks. 

 On a border to a house winter-forced, that is, where forc- 

 ing commences in December, this quantity of manure 

 would be doubled by the renewals. It is true that you 

 would have about half the original bulk of the manure
