Mr. Editor: - Being curious to see the above work, by the modest manner in which its coming was heralded, I purchased a copy; and believing that I have paid pretty "dear for my whistle," I beg you will allow me to say a few words in relation to its contents.

In all the very small book the author does not advance a single idea that can be claimed as original. It is merely a very meagre relation of the: practice of private European gardeners, which our best market gardeners here discarded years ago, nearly as long since, in fact, as the lumbering stage-coach has been discarded for the locomotive. We should not have noticed the work in question if the author had confined his advice to private gardeners; but when he specially dedicates to market gardeners his " old fogy" practice as a new system, or even a good system, then we beg to tell him, and any unfortunate tyro into whose hands it may have fallen, of our method, and wherein we claim the advantage over Mr. Roessle's stage-coach practice.

First: all his directions about raising the plants in hotbeds are useless, from the simple fact that plants sown in the open ground in April and planted out in July will give excellent Celery the first week in September, which is as soon as it will sell in market - as soon as any one wants to eat it, except, perhaps, the guests of the Delavan House.

Second: the system of digging trenches two feet deep, prepared in the manner described by Mr. Roessle, and planting the Celery therein, will cost, in labor alone, nearly as much, by his own admission, (one cent per head,) as the average of Celery in New York market sells for ! not taking any thing into account for the manure or the ground. Another unfortunate admission he makes, and one which is our main argument against the trench system, aside from expense, is the fact, that when a trench is dug two feet deep, and a small plant of Celery, or any thing else, planted at the bottom, the first heavy rain-storm will wash down the sides of the trench, and consequently cover up the plants with the soil. Mr. Roessle says he has lost hundreds of thousands of plants in this way, and still his disastrous experience has not much helped him, as he only recommends rounding the bottom of the trench, which involves further expense, and would help matters very little.

Nearly all the Celery sold in the New York markets is grown as a second crop; (Mr. R. never refers to it as such.) Our ground is first heavily manured in spring for our crops of early cabbages, beets, or onions, which are sold off usually by the first week in July. The ground is then cleared off, plowed, and harrowed, and at once planted with Celery, if the ground is moist enough to receive it. The Celery is planted in rows four feet apart for early, and three feet for the late crop - plants in each case six inches apart - all on the surface of the ground. This is what is technically termed the " flat" system. We never manure specially for Celery unless the crop preceding it has been neglected, and then we manure over the whole surface, as any one of experience knows that the feeding-ground for the roots is not confined to six inches on each side of the plants, but that they will meet in the centre of four-feet rows; hence the absurdity of manuring only in the rows. The culture of the crop by the " flat" system is very simple. In a week or so after planting, the ground is run through by the triangular hoe harrow; this is continued at intervals of ten or twelve days throughout the season to keep down the weeds and stir the ground.

A man and horse cultivate four acres per day, or something near 120,000 roots, which, by the trench system, would require all to be hoed by hand, involving at least twenty times the amount of manual labor.

As soon as the Celery gets to be fifteen or eighteen inches high, instead of the hoe-harrow we use a plow to throw a slight furrow to the Celery; then the "handling " or straightening-up process is gone through with and a heavier furrow is then thrown against it. It is then allowed to remain eight or ten days to extend the hearts, when the banking process is finished by the spade. This is the practice with what we sell in September, October, and November. That which we put away to preserve for winter use is done the same with in every respect, except that it is not banked up by the spade nor blanched in any way before being put away.

This brings us to another part of Mr. Roessle's system which we most emphatically condemn - "the burying away of Celery for winter." The practice, as described by him, is the same in every particular as was used by us about ten years ago. Since then our present plan has been almost universally adopted, the last of the "old fogies" having succumbed some years since. Having been engaged in the practice of both modes, I will "state as a fact, that in the method recommended by Mr. R. (which we termed "store-beds") ten men were required to put away 5,000 roots per day; now the same number of men, by our present method can, with much lighter labor, put away 25,000 per day. Now, as this is a much-mooted point in Celery culture, I will endeavor clearly to explain the way we manage it.

The crop being all handled and straightened up, we begin to put away what we want for use through December on the first dry day after the 25th of October, (dates are of great importance for localities of the same tempera-ture, though Mr. R. seems to ignore them altogether,) and so continue until we finish, which we usually do about the 15th of November; any later, in our district, is dangerous for frost; earlier, the Celery will whiten too quick, and rot.

Our manner of preserving is to choose a sandy, or at least a dry spot, in an open exposure, stretch a line, and dig a trench or drain ten or twelve inches wide, and of the depth of the Celery to be put away. It is then dug up, the earth well shaken from the roots, and packed perpendicularly in the trench or drain just tight enough not to bruise the stems. No earth is put to the roots whatever, the damp soil in the bottom of the trench giving out moisture enough to nourish the roots sufficiently for all purposes of blanching. It will be understood that the trench or drain is simply packed full of the Celery - an easy process, which any man can do, while by our old system, recommended by Mr. Roessle, very few men can be found to do it without considerable practice.

But our preserving process is not yet complete. Supposing we finish by the 15th of November, in this partially secured state it will withstand almost any frost we ever have during that month; but by the beginning of December we throw on the sides of the trench, so filled, about three inches of stable manure, yet still leaving a strip of green uncovered to permit evaporation; if closed up at once it will ripen too quickly. About the middle of December we make our final covering of six or eight inches of rough stable manure, pretty firmly packed down with the back of a fork over the tops of the Celery, and for one foot on each side, so as to prevent the severe frost from striking in from the sides of the trench. Our whole process of Celery culture is then finished, when it is ready at any time, or in any weather, to be taken out for market, no other trouble being required but to remove the straw covering and lift it up with the hands. By this plan of preserving we do not lose five per cent., while by that which Mr. Roessle's book treats of our losses were at least twenty-five per cent., and Mr, R. must have been unusually fortunate if his were any less.

Another matter that seems to exercise Mr. Roessle very much is what he terms our disgusting practice of covering with stable manure, and assumes, with great self-complacency, that that is the cause of the rust he saw on some of the bunches in the New York market. Such a silly assumption as the last it is hardly worth while to refute; but if manure in contact with esculent roots is disgusting, the wonder is why he ever recommends its use at all, as I think it would give him some trouble to tell us how he manages to keep it away from the cuticles of radishes, potatoes, carrots, etc., which would be equally contaminated by it as the cuticle of the Celery stem. The rusting of Celery is from some other cause which we have yet to learn, although Mr. R. so triumphantly settles it to his own satisfaction.

There are some other matters that I will just allude to in this Celery book. He says that the trenches should only be prepared when the wind is either north or west, and that he will then plant without regard to rain, and never waters. Now I would like to ask him, or any other practical man, if he had planted Celery in such a summer as the past, where in most localities there has been no rain for thirty days, with a burning sun and high temperature, would there be a single plant alive? This smacks a little of our Jersey Dutchman's "moon-planting," of which we have still a few victims left.

Again he says, " Celery plants should never be topped before transplanting: leaves are the lungs of plants, and can no more be dispensed with than the same organs in animals." In this matter we are by no means so tender-hearted as our worthy author, for we mow off with the scythe at least three inches of the "lungs" twice in the season before transplanting, and yet in nearly half a million which we grow annually have very few consumptive subjects. Mr. R. has evidently a genius for arriving very rapidly at conclusions which seem quite satisfactory to himself.

The gentleman informs us that he is about to treat us to another hand-book on gardening products, and is going to give as his next, " How to raise a Potato Crop without 'Rot.'" What a world-wide philanthropist he will become ! Ireland will be regenerated forthwith, and the green isle be again made to "blossom as the rose." Hurry up, Mr. Roessle ! don't let starving thousands droop that might be saved by a few strokes of your magic pen; don't keep us longer in suspense, and you will much oblige.

A Jersey Market Gardener.

[It is sometimes a very pleasant thing to fall into the hands of a Jersey-man; what Mr. Roessle will think of it in this particular instance we can only imagine. We have heretofore said, that in many respects we should be loth to follow Mr. Roessle's practice; and most practical men will probably agree with "A Jersey Market Gardener," that Mr, R.'s advice should have been confined to private practice. - Ed].
