Drip in Curvilinear Greenhouses. — A New 

 York correspondent says: — I am under the necessi- 

 ty of doing something to the roof of my greenhouse, 

 which has always leaked dismally. It was erected 

 in 1863, by an eminent person on whom I relied 

 for a good house, but the result was a veritable 

 bungle. 



The roof is curvilinear, (lean-to.) The upper 

 half of the roof has not pitch enough, and the whole 

 of the glass has been laid on with the least possible 

 overlap. The result is, that during rain, a large 

 quantity is admitted, and drops down on the plants, 

 &c. It is much worse near the roof where the 

 glass is so flat. 



I propose removing the glass on the roof and re- 

 laying it with sufficient lap, unless any other plan 

 can be adopted less laborious and equally effective. 

 I have thought of closing the openings with Hil- 

 ton's Insoluble Cement. Do you think that would 

 answer ? 



I have no faith in any plan but relaying the glass. 

 How much lap do you think is ample to check the 

 admission of water ? Does it answer to close the 

 lap over with the cement named? What would 

 tend to check the escape of heat during severe 

 frost — a most desirable consummation in my case — 

 not having enough in the hardest frosts. The 

 benefit of your opinion on these matters will oblige 

 your correspondent. 



[If the laps are made tight with already not 

 enough heat in the house, we should fear mois- 

 ture would condense, freeze, and, in thawing, 

 "drip" worse than ever. If broad laps are made 

 in a flat hou^e, moisture will collect under the lap, 

 freeze, and crack the glass. Our correspondent is 

 ; in a bad way. If any of our readers can help him, 

 I we shall be glad to have their experience. We 

 have always opposed curvilinear houses for our cli- 

 mate. They look pretty, but are not "practical."]

Roses in a Cold Greenhouse. — Anxious In- 

 quirer, New London, Conn. — I have a well glazed 

 house in a sheltered, sunny position, with a deep 

 rich border, in which I design to set out tender 

 roses. Will they live through the winter without 

 fire heat? (1) Will it be necessary for this purpose 



to cover them with leaves or with earth ? (2) 



[(1) Yes. (2) We have seen roses, during the past 

 year, of the most tender kinds, in pots, kept in a 

 house where there was no fire, without any material 

 injury; and we judge from this that, in the earth, 

 they would do still better. We saw Violets, and 

 other such hardy things in the same house, and no- 

 ticed the leaves, in places exposed to the sun, were 

 a little injured, — showing shade to be good under 

 such circumstances. A covering of leaves or any- 

 thing we should hardly deem necessary.] 



Grass Under Trees. — Anxious Inquirer, New 

 London, Connecticut. — Is there any grass or green 

 moss that will thrive in the shade of low, drooping 

 Elms in good soil ? Our magnificent Elms have 

 this drawback, that (where they grow low and droop- 

 ing) they suffocate ordinary grass in spite of all pos- 

 sible care. 



[Several Hypnums, — a shade loving genus of 

 Mosses, — will live under trees, and make a nice 

 green carpet after every good rain ; but it would be 

 brown in dry weather. It would be best, perhaps, 

 to plant with Ivy or Periwinkle, which will do 

 well.] 



Letter from Mr. Hacker. — Philadelphia, July 

 23, 1867. Dear Sir : — I send, same mail, a sample 

 copy of the new Illustrated Monthly, the "Ameri- 

 can Journal of Horticulture," with which I hope 

 you will be so well pleased as not only to subscribe 

 for it yourself, but use your influence to induce 

 others to subscribe also. It is the intention of the 

 Editors and Publishers to make it a Magazine which 

 shall be of interest and value in any part of the 

 country. Practical correspondents have been en- 

 gaged, from all sections, to give the benefit of their 

 experience, and everything will be done to make it 

 what its title indicates. — the "American Journal of 

 Horticulture." 



The subscription price is fixed at $3 per annum, 

 so that it is within the reach of all. The value of 

 the contributions and its fine typographical execu- 

 tion should command a large circulation, and, I 

 hope you will lend your influence to the enter- 

 prise. 



I send, herewith, my Catalogue, to which the at- 

 tention of the trade is solicited. 



Very truly, yours, William Hacker, 

 Wholesale Seed Merchant, Market St., Phila. 



[In reply to the above note of Mr. Hacker's, we

 the A. J. H., and that we have already used, and 

 shall continue to use our influence to extend the 

 circulation of the magazine. There is abundant room
