A "Horticulturist on a very small scale, having only 4 pear trees and six grapevines," (dating at Pittsburgh,) writes us an account of his mode of feeding a large Catawba grapevine, which may interest some of our suburban readers. He forms a large basin around the Toots of his grapevine, early in the spring, by raising a curb or box of boards, so that the soil over the roots will take a couple of barrels of water without allowing ft to run to waste. He provide* himself with a quantity of the sweepings or manure of the poultry yard, keeping it constantly diluted or dissolved In a barrel, at the rate of a peck to a barrel of water. Every week, at the close of the "washing day," he first empties upon the roots of the vine a pailful of the manure water from the barrel, and afterwards as much of the " suds'1 as the vine wit! take up. The consequence, as may be expected, is a great lxuriance of vine, and enormous clusters of fruit. A very large back, building is covered by this vine, and the fruit is just twice as large, in bunch and berry, as those on the other vine, left to ordinary good garden soil.

A neighbor, who bad an old Isabella vine that bad failed for several years to bear any good fruit, has taken the hint, and applied the "weekly wash," with the fertiliser as aforesaid, and has been gratified with a larger and more promising crop this year, than the vine ever bore previously.
