Mr. Editor: We did not expect that our article in the March number of the Horticulturist on imported roses, would meet the approbation of all dealers; but we cer tainly did not expect an opponent from such a quarter; for we supposed that a man situated like Mr. Bridgeman, was better posted as to what was going on in his own country, and especially in his own State.

His first question is, "What nurseryman or florist neglects to produce Roses himself, and thus allows his simple vanity to get the better of his judgment V I know of no one better able to reply to this than the gentleman himself, for he acknowledges that he imports roses for his customers. But we ask the gentleman's pardon for using the word " vanity," it should have been " ignorance".

Second. " Have not American Roses of decided merit, brought as good prices and as ready sale as new French Roses? So far as prices are concerned perhaps they have, but they have brought no better prices than new Roses in Europe. But as to rapid sales, it is very doubtful whether there are more than one or two instances where there has been received by the producer anything like a fair remuneration.

The gentleman says that he receives new Roses in limited quantities among his importations without extra charge. Did he ever know an American nurseryman refuse to put In a limited quantity of new Roses without extra charge, provided he purchased by the hundred or thousand? We have not yet learned that French nurserymen were any more liberal to their patrons than American nurserymen.

Third. As the gentleman seems to doubt there being a place in this country where Roses can be procured of the leading varieties in quantities; we beg leave to state that we know of several, and we will name one in particular, who propagated one hundred thousand last season, and had forty thousand on hand at the close of the season, just because such men as Mr. Bridge-man import Roses instead of buying them at home. We refer to Messrs. Ellwanger & Barry, of Rochester. As to quantity, quality, or choice varieties, we* refer the gentleman to their catalogues or to their grounds.

Further, they have been selling these Roses at $160 per 1000, which is less than the price stated by us, and less than Mr. Bridgeman says he can import them.

If Mr. Bridgeman will send his orders to Ellwanger & Barry, one, two, or three months in advance, the same as he has to in sending to France, we think he will find his orders filled promptly, and with choice varieties; those known to be good of all classes.

Fourth. "Where can Roses be purchased for seven cents apiece in France? "Well, we thought we would tell, but upon further consideration we think we had better not, as we may make something out of gentlemen who pretend not to know; but certain it is that Roses have been and can be still bought in France at that price, and almost every season for four cents. If Mr. Bridgeman doubts us we will give him the names of several gentlemen who will import them for him at seven cents; he of course paying freight, Ac.

We have always objected to putting down the price of nursery stock of any kind, and we thought that our statement was high, and on some items, nearly double what it sometimes costs; for instance, freight from Havre to New York, was per steamer, when very few import by steam, mostly by sailing vessels, which costs much less.

Mr. Bridgeman is curious to know what I mean by Angers being the Rochester of America, why simply that Angers is supposed to be the great nursery depot of France, and Rochester the great nursery of America, as well as the largest in the world.

As to any nurseryman in this country supplying 20 to 200 of one variety, and to allow the purchaser to name those varieties, and certainly if he ordered one or two hundred of each, there is probably no nurseryman in this country or in Europe, that could fill such an order without buying of his neighbor. We doubt very much whether Mr. Bridgeman ever had an occasion to give such an order. And we wish the gentleman to understand that we do not say that Roses can be purchased in France at $70 per 1000, if the nurseryman is restricted to certain varieties, neither can he purchase large, strong plants of Hybrid Perpetuals in this country for $160 per thousand, under the same rule. But if he gives his order for so many thousand Roses, assorted varieties, then they can be had here at $16, and in France at $7 by the thousand. Andrew S. Fuller.

Mr. Editor:- At what price would it be profitable to purchase bones per pound as a fertilizer? We are frequently urged to save and collect such materials, and prepare them for the improvement of certain crops. I presume many of your readers would be equally pleased to receive a direct, practical answer to the above question. If it will pay to take the trouble to gather the bones scattered over a farm or about a town, it must be economy to pay something to have them collected to order. Very respectfully, N. Y, April 9, 1861. A Subscriber.

[At the rate of $30 per ton, it will pay you to collect all the bones you can find. Bones about the farm or the town, or from the butcher, are worth a good deal more than the crushed or broken bones usually bought at factories, since the latter have in most cases been boiled, and have thus parted with important elements of fertility. Our advice to you, and all others is, to collect all the bones you can find. - Ed].
