the house, is calculated to preserve the frame from decay, as the less joining of wood about 

 a greenliouse the more durable it will l>i'. To illustrate the drawing, lot a be the ridge. 

 b. Rafter, c. Stretcher, or running raft, on which rest the sash bars (d). e. Tlie sides of 

 ventilator, into which is framed the upper end of the sash bars, being narrowed to the 

 under side of sash bars between the rafters, as shown on Fig. 3. f. Caps covering the 

 opening half dovetailed and liinped together as shown in Fig. 4. 7. The gutter into which 

 is framed the lower end of sash bars. h. Iron rod passing through the ridge, and secured 

 firmly to the cap, the lower end connecting with the lever under the staging, as in Fig. 1. 

 I. An attachment to be applied when a passage-way is required through the centre of the 

 house, or to suit the construction o^the staging, one end secured to the rod, the other end 

 secured to the lever under the staging by a stout wire (see Figs. 2 and 1). j j. Levers 

 under the staging operating on the cap, opening it any distance required, and secured, up or 

 down, by stationary or movable pins placed in the frame of staging. 



We have lately erected a greenhouse in connection with our place of business according 

 to this plan of construction, drawn by Gamaliel King, Esq., Architect, of Brooklyn, N. Y., 

 and find that it answers the purpose admirably. 



Any further exjjlanation you may deem reqiiisite will be cheerfully given, and any im- 

 provements that may be suggested will be as gladly received. 



Very respectfully yours, Andrew Bridoemax. 



Akswers to Correspondents. — (.J. P. H., New Orleans). Your beautiful berried plant is 

 the Ilex rassina. A few jdants exist in our vicinity, but, in most winters, require protec- 

 tion. Very few broad-leaved evergreens will stand the test of a Philadelphia winter — at 

 least, such winters as the two past liave been. Many thanks for your kind favor. 



(N. C, Oregon). No. 1, Clarkia pulchella. This beautiful annual is extensively grown 

 in our Eastern gardens. No. 2 we do not recognize from the seed-vessels sent. The yellow 

 flower belon"iiig to the seed, in the same package, is of EschoUzia californica, also well 

 known here, and appreciated. No. 3 is Oenothera Drummondii. The other two specimens 

 of bulbous flowering jjlants we do not recognize. The blue one appears to be very hand- 

 some. We shall be pleased if we succeed in raising them, but little success, we fear, will 

 crown the attempt to raise two year old seeds of a liliaceous plant. Most of the handsome 

 annuals of your country have been sent to the horticultural world by Douglass, Nnttall, 

 and other collectois. There are doubtless things that would still prove very acceptable, 

 especially such plants as ripen their seeds early, and before the time of year the parties 

 alluded to explored for them. 



(A. D. Jones.) The Herb of Grace of the old writers was the Rue {Ruta graveolens of 

 Linn?ei;s), and was considered of great efficacy, in medicine, for children as a vermifuge. 

 Ophelia, in Shakspeare's Hamlet^ says to the Queen : " Tliere's rue for you, and here's some 

 forme ; we may call it herb of grace, 0, Sundays !" The gardener, in Richard 11., says of 



the Queen : — 



"Here did she drop a tear ; here, in this place. 

 I'll set a bank of rue — sour herb of grace : 

 Rue even for ruth, liere shortly shall be seen, 

 In tho remembrance of a weeping Queen." 



(S. S.) You are in error in supposing there are no scented camellias. "Park's Striped 

 Rose" is slightly odoriferous, as is the myrtle-leaved variety ; but you are correct in wish- 

 ing the tribe were more generally so. 



(J. G., Leesburg, Virginia.) Your question is rather indefinite, as you do not say how 

 far the "young gardener" has progressed in his studies. Loudon's Encychpcndias of 

 dening and of Plants, are the best, and, for a " beginner" in botany, there is no book
