At the end of the Grape season, I feel inclined, from habit, or a better reason, to make a few comments on the past, but not to put on airs of importance, for I have but a small vinery, and nothing to recommend my speculations to the public but a love for the study of vegetable physiology, and a habit of careful observation. It is well, also, for gardeners in different latitudes, and with different facilities for producing fruit, to "compare notes." Such opportunities have been useful to me, and I suppose to others also. In my house are ten or eleven fruit-bearing vines, on which about one hundred clusters were allowed to mature. A part of these vines are six years old from the bud, and others only four years. The number of bunches was regulated by the age and strength of the vine. In 1853 some of them were over-cropped, and therefore care was taken not to fall into the same error again. If, by reason of a deficient border, or unskillful management, or deficient sunlight, the vines have made but a slow growth the first two or three years, there is groat danger of over-cropping.

With some, it has been a question whether it be expedient to use artificial heat, even in a slight degree. The grower of Grapes for the market will consult his pecuniary interest by pursuing one course or the other, or perhaps both by using two different vineries - one of them to be a forcing-house; but with the amateur, who studies the gratification of himself and family, the case may be different We speak of a gentle forcing in April and May, by the cheapest mode, which is any old stove with a boiler, to produce constant evaporation, and thus supply moisture.

The advantages of this hastening of vegetation are as follows: You will gain some two or three weeks in time. Your Muscadines, or Chasselas, will be fit to cut early in August, when no others are ripe; the Hamburghs will be ready early in September; and the White Muscats about the middle of the same month. Being ripened in hot summer weather, they will be very sweet, having their peculiar aroma well developed; and this is a luxury which can not be enjoyed under other circumstances. I have seen this favorite variety, which, on the first of October, was said to be ripe, but the flavor was deficient, and the color green.

But again, there may be another contingent advantage of a little fire heat. It sometimes happens that in the latter part of May, when the vines are in bloom, there will occur two or three successive days of disagreeably cold and wet weather; the temperature will get too low, especially for the Muscats, and the impregnation will be imperfect Whether it be owing to an immature state of the pollen, or to some other cause, is immaterial, the result will be Grapes badly set At that critical time, let the temperature be raised from fifteen to twenty degrees, and all will go well.

If it be objected that warming is expensive, and we may as well leave it all to nature, we reply, What is the expenditure of two or three dollars for a cord of ordinary wood, in comparison with Grapes well set, and ten days acceleration of the fruit?

The roots, also, running into the outside border, may be stimulated by laying over them some old sash, which can often be bought for half the customary price.

We are here led to say a few words on the operation of heat and moisture, the two chief stimulants of vegetation.

The business of watering will be a light labor until June, as the soil is saturated in winter, and the evaporation proceeds slowly till the middle of June; but then, as the days are long, and the solar heat becomes powerful, there should be no lack of moisture. No doubt many vines throughout the country, during the past summer, suffered for the want of water. The result was, a limited growth; but when the fruit matured, it was found to be of an excellent quality. Very different was it the previous year (1853). Very fine showers fell in August, and did no injury; but heavy rains continued to fall at short intervals throughout September, and the outside border became completely saturated and prematurely cold. The result was, the Grape juice was too much diluted, and the flavor comparatively tame. The peculiar sugar of the Grape was developed and concentrated last year much beyond what is usual; so what we lack in quantity is compensated for in quality. We learn from these facts, that when we have too much rain, we must contrive some way to shed the water off. About the first day of July, when the clusters should be thinned out, the showering should be diminished, and care be taken not to wet the Grapes. Their beauty will be greatly injured by destroying their bloom.

I made such a mistake in 1853.

The use of sulphur to prevent mildew, is supposed to be well understood and appreciated. The danger will commonly be in the month of August Near the last of the month we had, in this locality, two successive days of cloudy, damp, hot weather. The Muscat Alexandria were full grown, and beginning to change color on the sunny side. On the opposite side there was, on some few berries, a beginning of mildew At once I separated them a little, and applied a little sulphur. From that day the plague ceased; and when the Grapes were ripe, and cut from the vine, the tarnished spots were of a rusty appearance, and not of large size, but the Grapes were good.

Such has been my treatment; and what of the results ? They have been, in a great measure, satisfactory. It is indeed a delicate matter for me to speak; but I venture to say that some specimens of Black Hamburgh, White Muscat, and Cannon Hall, which were shown at our town Fair, were much admired for their rich color, full maturity, and perfect beauty. Some berries of the Cannon Hall measured three inches in circumference.

Care should be taken, that water for the border be of a proper temperature when applied. A friend sent me a load of water from the lake, in the midst of the drouth, and after stowing the greater part, some buckets were thrown upon the outside border. The next morning I observed a few of the Muscats, then full grown, were discolored, and beginning to shrivel. At first I was surprised; but a little reflection indicated the cause. The check had been too great; for, howsoever grateful a tepid bath may be, the cold bath is a part and form of hydropathic treatment which they repudiate.

I have just read the November number of the Horticulturist, and am highly delighted with the account furnished by "Amateur." I hope to give, this year, some statements of progress in Mr. King's grapery, built on the same model I conclude by saying, that I fully ripened some Catawbas last season, by protecting them in the spring, and then, on the first of June, tying them up to a trellis in the open air. Early in October they were again laid down under glass; and on the 25th of the same month they were fully mature, - so said my neighbor, who last year was treated to the same variety in Mr. Buchanan's vineyard at Cincinnati At a convenient time I should like to say a few words more about protecting the Catawba.
