For raspberry vines that require support there is no contrivance more simple, durable, and cheap, than a single wire stretched along the line of the row, and fastened to posts driven into the ground every thirty feet. No. 14 wire will be found quite strong enough. This is the size manufactured for use in Western vineyard*, and for making grape trellises, No. 14 is preferred to a heavy wire. The figures below give the cost to the writer of putting up nine lines of this sized wire on as many rows of Philadelphia raspberries. These rows are seven feet apart and 460 feet long - a patch occupying not quite three-quarters of an acre. The wire was bought at the factory, 20 Per cent. off the retail price. A roll that measured when drawn out a little more than 4,000 feet, cost $6.50. The chestnut stakes, six to seven feet long, made from the tops and branches of trees felled last winter, were cut and sharpened by an ax-man in one day, at the expense of $1.50. It took two men and a boy half a day to make the holes with a crowbar, drive the posts, and fasten the wire. Outlay for this, $2.25; wire staples for fastening the line, 75 cents; total, $11. With an occasional rotting stake to be replaced, this support will last at least five years, with a mere trifle to keep it in repair.
Both for raspberries and grapes stretched wire has been found better for tying than when single stakes are used, and raspberries fastened to wires can be picked much faster than when the Tines are left without supports or tied to stakes. - N. Y. Tribune.
