Mat is a busy month in the vegetable garden. Peas want hoeing, and perhaps brushing; early beets, parsneps, carrots, etc., if sowed the last month, want weeding. If not sown, the sooner the task is done the better for your chance of long, strong tubers. Make the ground deep and mellow.

Melons, cucumbers, sweet corn, squashes, beans, etc., all to be planted this month.

Keep the melons and cucumbers and squashes each a good distance apart, if possible. Tomatoes when first taken from the frame and planted should have a box around them a few days, until their roots get newly established. The same also of melons and cucumbers taken from the frame. In making melon and cucumber hills, put in plenty of well-rotted manure, and distribute it wide as well as deep. Lima beans want rich, well-manured soil, or they give but a poor return. Celery plants need to be pricked out into a gentle spent hot-bed frame. Cauliflower plants, as well as cabbages, are benefited by adding a handful of bone meal in each hill where they are to be planted.

Messrs. Editors : John F. Bennett, Esq., in the April number, asks if, in the weedy vineyards where I saw as much rot as in those of clean cultivation, the "weeds were free from rot?" Truly, I can not answer him yea or nay. My recollection is, that the weeds were at the time, most of them, in what would be termed a ripened state, and hence decaying; there might have been fungoid upon them - I do not recollect of noting it. I have a great respect for the dead, but do not regard the remarks he made when alive as any more infallible than if he were still alive. The mind of man improves and changes from year to year, and many a man makes remarks at fifty which at fifty-two he would be unwilling to substantiate. Reuben.

If you expect to gather good fruit, or large and fragrant flowers, keep the soil frequently stirred; never let it get packed down and dried. If drought comes, the more you stir the land the better. Soil stirred after four o'clock p. m. will absorb dew almost equal to the effect of a small shower. Many years ago, we kept a large nursery fresh, green, and growing all summer, by keeping our plow and cultivator working from three p. m. to dark, and sometimes a little on moonshiny nights.

Grass fields all around us were burned out. forests were brown, and yet our trees and plants grew on as usual, and all by means of constant stirring of the soil.

Dahlias may be planted out any time after the 10th of the month. Deep, moist ground gives the best growth and blooms; while as manure, we have never found anything equal to a weekly application in liberal quantity of soap-suds water and chamber lye.

Wethersfield, Conn., March 14, Mot.

Messrs. Editors: Two years ago I noticed an apple-tree in full and vigorous bearing, while those in its neighborhood had been badly eaten by the canker-worm, that great scourge of our New England orchards. Against the trunk there had been made a heap of coal ashes, the refuse of the winter's fire. Judging this to have had the effect to prevent the ascent of the insect, I last year tried the experiment on a few trees, with perfect success. The grub was kept off from trees where the ashes were applied, while trees immediately around it not thus protected were badly eaten.

Should this prove a remedy after careful trial, it will economize and divert to a new use this hitherto useless product of our coal stoves.

I applied it to several plum-trees which had previously borne sparingly, and the result was an enormous yield the following season. J. W. Griswold.

Stir the soil carefully around Japan lilies or other bulbs that are now coming strong out of the ground.

Correspondence #1

To Cure Smoky Chimneys - as desired in your number for April (p. 123) - place on the top a sheet-iron fixture as large as the flue, expanding as it rises, in the proportion of three at the bottom, four at the top, and fifteen high (say twelve inches bottom, sixteen inches top, and five feet high), and if the flue be about twelve inches, cut out triangles six inches deep and three inches wide at the top, forming a crown of saw-teeth.

These proportions were given to me in 1837, by Mr. Oldham, the engineer in charge of the mechanical department of the Bank of England, when he called my attention to the draught of the flues in the press-room, and then to the fixture on a neighboring chimney, and said that these rooms were almost uninhabitable when he came there, until he applied the same fixtures that he had previously used on the Bank of Ireland, and that had cost that bank about fifteen hundred pounds in experiments.

But if the top of the chimney be not above all neighboring objects, then take the same proportions in a curve, and place the adjutage on a swivel. This was done about 1842, on the flue of the House of Representatives, at Washington. The difficulty there arose from the dome. The cure was complete, as long as the experiment was tried. But in a short time a patentee obtained a contract for several flues, and his arrangement was substituted.

Again : a well-known patentee of cooking-stoves said: "I never have less than twelve feet height of pipe above the stove. If I can not get it in the room, I put the pipe inside the chimney, and I never fail in getting a good draught."

The Venetians generally use bell-muzzle flues, but they spread more rapidly than Mr. Oldham's proportions. B. A.
