Peter B. Mead, Esq. :- Sir: In an article on inside detached and divided vine-borders, published in the May number of the Horticulturist, Mr. Bright states that"neither the' Book of the Garden by Mackintosh, nor any other English work or journal, has, to my knowledge, described or suggested inside divided vine-borders." Now you will find that Hoare, in his work on the vine, republished in New York in 1847, strongly insists on the border being entirely inside the house, and, on page 79, says: "Carry the walls up hollow as high as the adjacent soil;" and, on page 180, across the inside border build " solid walls, for the purpose of keeping the roots of the vines separate from each other," same as Mr. Bright. Again, in Loudon's "Suburban Horticulturist," ed. 1842, there is a section of a vinery with inside border raised above the ground level; and in Johnson's " Gardener," ed. 1853; vol. iii., page 80, there is a section of a vinery with inside border, in which the Rev. B. Cooper for many years raised an abundant and an early crop of grapes.

Yours truly, Hoboken, July 7,1860. Dr. D. Benson.

[Mr. Bright has already conceded the point of originality in regard to inside borders; and it is quite possible for him to have made an inside border without having seen the works of Hoare and Johnson. It is probable that Mr. Bright may have something further to say on the subject.- Ed].

P. B. Mead, Esq. : - Dear Sir: In answer to your inquiries touching the mildew upon the gooseberry, I would first state, that about eight years since I purchased three dozen of the best named English varieties - say, Melting's Crown Bob, Framer's Roaring Lion, Caper's Top Sawyer, Dixon's Golden Yellow, Wainman's Ocean, Whitesmith, Ironmonger, and others of III equal celebrity at that time - and planted them in the best localities in my garden. For five years they grew beautifully, always heavily laden with blossoms; but when the fruit grew to the size of a pea it commenced mildewing, and daring the period of five years I could not get one ripe berry, as they would bunt and fall prematurely to the ground. I tried every remedy that could be suggested, but my efforts proved "fruitless." I had planted a cherry currant-bush in close proximity to one bush, and it mildewed the currants, as well as also the leaves of it. Such were the alarming effects of the pest, that I determined to dig them of and "throw them to the dogs/' when a lady of Westchester county (whose name I am not at liberty to mention at this time, neither am I privileged to state the process, which costs nothing but a little labor) begged permission to try an experiment on my bushes - which was about three yean since - and the result is, that during all that time my bushes have been laden with most delicious fruit, each coming up to its name.

' As the lady in question is extremely modest in her aspirations, she has been unwilling" to place her discovery at the disposal of the public until she was thoroughly convinced of its efficacy. I think, as far as my judgment extends, we have sufficient test to pronounce it a perfect specific for the mildew upon the gooseberry. Since the reception of your note, I have gained her consent to request the proprietors of the Horticulturist to appoint a committee to visit my garden and examine for themselves, and report accordingly. The berries at present are almost full grown, and promise as well as former crops, and when ripe I shall take great pleasure in presenting specimens to you of each variety: at the same time, if I am released from the injunction of secresy, to impart the process, to be laid before the public through the columns of the Horticulturist.

Morrisania, June 27th, 1860. GEO. H. HiTE.

[Having heard much talk of Mr. Hite's gooseberries, and their freedom from mildew, we wrote to him, asking for information, in response to which we received the above. We have visited bis garden, and found his gooseberries to be just as represented, free from all signs of mildew, and in other respects very fine. We did not learn how the result was effected, but the subject will go into the hands of a committee for examination and report. If there is anything in it, we do not believe it is for the interest of any of the parties to keep It a secret; and if it is anything that ought to be paid for, we are willing to pay for it Let us first know what it is. - Ed].

Editor of THE Horticulturist: - Sir: In reference to the remarks on Lilium Phila-delphicum, in this month's Horticulturist, permit me to state that my bulbs of the same, when fully grown, produce from 17 to above 20 blossoms; but, last fall, I added to a cube of about 18 inches of good garden soil a gallon or more of crushed charcoal, and planted therein three fine bulbs of L. Philadelphicum; one of these bore 48 blossoms, another about the same number, and the third 54. They made a magnificent group for a considerable time, as the blossoms were successively developed.

I use charcoal with much advantage to plants in general. It gives brilliancy to my tulips, and increases the size and number of bulbs and blossoms. I have frequently five blossoms from one bulb, and two and three blossoms from one bulb is very common.

New Harmony, Ind., August 7th, 1860. Margaret Chappellsmith.

[Your lilies must have been a beautiful sight. We have heretofore strongly recommended the use of pulverized charcoal, and do so again; for pot-plants it has a special value. - Ed].

Editor Horticulturist, New York: - Dear Sir: I notice, at page 377 of your last number, that reference is made, by "A Bufialonian," to the report circulated last autumn, and then inserted by you and others, that" Delaware grapes had been found in three different locations in a wild state." Your Buffalo friend does not appear to be posted as to the latest intelligence on the subject. If he will refer to the columns of the Horticulturist, and to the "Germantown Telegraph/* where the canard first started, or to any member of the Pennsylvania Wine-Growers' Association, of which Dr. J. B. Garber is a distinguished member, he will find that a thorough investigation of the matter took place, ending in a complete refutation of the silly fabrication, and in proving positively that not one Delaware vine existed but 'what was traceable to the vineyard of foreign vines imported by Judge Provost, of French-town, N. J. I visited the town of Delaware, Ohio, last September, and, to my great surprise, I found but one Delaware vine in bearing, and that was trained against the south side of Mr. Campbell's stone house, and was so sheltered that any of the Chasselas grapes would mature their fruit in the same position.

The evidence of its origin, and the character of the plant itself, are so conclusive as to its foreign character, that I did not suppose any man of careful observation could entertain a present doubt on the subject. I well knew, when I first presented my views, that self-interest would be startled when the public has been so egregiously misled; but I also knew that one year's observations would confirm the truth of my position. I long since prepared an article specifying the distinct characteristics of the foreign species, Viiia vinifera, when contrasted with our indigenous species; whereby it is proven that, while the Delaware has all the attributes of the foreign species, it does not possess one solitary attribute of our native species. I have also been gathering other facts and evidence, but have deferred their publication, awaiting the general opportunity for investigation which another fruiting season would afford to the public at large. Tours respectfully, Flushing. August 13th. 1860. Wm. R. PRINCE.

[The above was received after Mr. Garber's article was in type. It is too bad to place "A Buffalonian" between two fires, but we suppose he can stand it. When Mr. Prince gets all his facts and evidence together, we shall be glad to have them. Meantime, we shall give the subject further investigation. - Ed].
