5G BRIGHT ON GRAPE CULTURE. 



but also, at all seasons to equalize the temperature of 

 the border and the house, which is of great importance 

 in vine culture. These air conductors are to be laid in 

 the drainage, above the concrete, and may be formed 

 by dry brickwork, making a tube four inches in diame- 

 ter, or by four inch tiles, connecting with the open 

 space between the border and the front wall, and open- 

 ing into the house on the inner edge of the border, 

 there passing through a wall of dry brick or stone, or 

 even boards, merely to keep the inside edge of the 

 border in place. 



The border, when constructed on this plan, will be 

 entirely detached from the soil, both inside and outside 

 of the house. It will rest upon drainage, laid upon 

 solid, impervious concrete, and will have a wall, de- 

 tached from the house, on the front and back. It will 

 be situated like the earth in a pot or orchard-house tub, 

 and will be, in fact, one immense pot or box, perfectly 

 confining the roots of the vines within its own limits. 



We feel entirely satisfied that this is the best method 

 now known of constructing a vine border. The shallow 

 border, entirely inside of the house, is now beginning to 

 be employed by some of the best grape growers in Europe 

 and America. The atmospheric conductors, though not 

 entirely original with the writer, have been more largely 

 employed and advocated by us than by any other writer 

 or practical grape grower within our knowledge.
