Garden Architecture. 



There has been a very great improvement in style of con- 

 structing greenhouses, conservatories, graperies, &c. Since 

 the introduction of the curviHnear roofs, first erected by Mr. 

 Gray, at Brighton, of which we have given an engraving, 

 (Vol. XII, p. 379,J many houses have been built in various 

 parts of the country on the same principle, with such im- 

 provements as would naturally be suggested, according to 

 the materials used and the locality for building. Several 

 have been erected in the neighborhood of Boston, by our 

 correspondent Mr. Leuchars, and we intend soon to give 

 plans and engravings of such as appear the best adapted for 

 general construction. The old lean-to roofs are ill shaped 

 structures, which can rarely be made to harmonize with other 

 buildings, and consequently must be located in some out-of- 

 the-way place, where they will not be conspicuous objects of 

 a suburban residence. The curvilinear houses, on the con- 

 trary, may be made really ornamental objects, especially as 

 detached buildings, and may be erected as near the mansion 

 as convenient without detracting from the general features of 

 the place. 



We notice that some writer in the Philadelphia Florist 

 speaks of a new mode of glazing, which he thinks should be 

 called the "American system." This mode is to set the glass 

 as heretofore, but instead of using putty on the surface, to 

 give the rebate one or two good coats of paint. Now this 

 system of glazing we were not only the first, we believe, to 

 adopt, but we have not finished a house on any other plan 

 for twelve years ! We can shoAV any one who will take the 

 trouble to look, four houses, eighty-four feet long each, span- 

 roofed, which are glazed on our system, — which certainly is 

 American, as we know not of its adoption anywhere else. 

 It is a great improvement upon the old plan ; with an occa- 

 sional painting, the sashes throw off the rain far better, and 

 there is none of the constant attention and expense of putty-
