experiments to all those ornamental trees and shrubs "which 

 are most likely to give improved varieties. 



Under this head, we may allude to the excellent article on 

 transplanting large trees, by our correspondent, Mr. Hender- 

 son (p. 248) ; not that we are great advocates for removing 

 large specimens, but merely to show that it can be done, — and 

 successfully, — when it is desirable to plant in some exposed 

 situation, or produce immediate effect in landscape scenery. 



The Public Garden in Boston, it is stated in the papers, in- 

 tend to rearrange their grounds, and plant at least one speci- 

 men of every American tree which will stand in this latitude; 

 if such is the intention, we hail it as the first really progres- 

 sive step which has been made since its organization. Had 

 the amount been laid out for the improvement of the grounds, 

 and the planting of trees, which was expended in purchasing 

 a large collection of plants, the proprietors, as well as the 

 public, might now have enjoyed the luxury of umbrageous 

 walks and shady groves, which a judicious arrangement of 

 trees would, in five or six years, have produced. 



Garden ARcmTECTUKE, 



The improvements in the erection of greenhouses and other 

 structures for plants, are rapidly extending. To aid in tliis, 

 we have given, agreeably to our promise, a full account of the 

 mode of constructing grapehouses on the Curvilinear plan, 

 first adopted by Horace Gray, Esq., of Newton, which has 

 succeeded so well, that a large number have been erected, 

 and others are now building in the same style. Our engrav- 

 ings at pp. 379 to 383 represent the manner of construction so 

 plainly, that any carpenter of moderate ability could erect a 

 building. 



To test its applicability for the purpose of forcing, in our 

 climate, as well as for grapehouses merely, we have recently 

 erected a hothouse, eighty-four feet long, fifteen wide, and 

 twelve feet high at the back ; with a roof facing the south 

 only, the ventilators being in front, and in the back wall. We 

 shall endeavor to give a plan of it hereafter ; it is now, as we 

 write, just put in operation. Grapes are intended to be planted 

 for forcing. It is fitted up with a pit the whole length, bottom
