Many persons appropriate the ground devoted to the main walks in their gardens by planting grapes, and so training them as to form an arbor under which they walk. It is undoubtedly a good plan, but by reason of the frequent renewal of trellis, or at first forming it of iron, is rather an expensive one. The apple and pear tree may be just as easily bent and trained to form arbors and produce fruit as the grape; and with this advantage, that when once formed they will continue the arbor of their own strength, and form without the aid of wire or slat-trellis. We grow fruit so easily, as yet, and land is so cheap, that we practice little economy in use of land, or study little the facility by which the growth of tree and plant may be directed to any point or form.

Mr. Editor: In the April number of the Horticulturist I notice a correspondent, Wm. Sumner, of South Carolina, says he has a remedy for rot in the grape. Now, let me propose to him to place this remedy in the hands of a few careful grape-growers in different sections of the country, imposing on them secrecy as to the modus operandi, and if they report favorably next year he may realize a handsome bonus for his discovery. I believe there is not one horticulturist in the United States that would be unwilling to pay a good price for a remedy against rot in grapes or curculio in plums.

Yours, etc., .
