ready brought together to ornament his conservatory. We passed sev- 

 eral other neat structures for plants, attached to the town residences in 

 Brooklyn, and were much pleased with the architectural taste shown in 

 their construction. 



New York. Mr. Thorburn, connected with his large seed store, in 

 John Street, has a rather unique appendage, viz. a handsome saloon, 

 fitted up as a picture gallery, where one may be entertained with some 

 excellent specimens of the art. There is also an aviary, for canary and 

 other birds, where we saw an immense number of these feathered 

 songsters, whose sprightly notes of melody quite filled the building. 



Jit Mr. Thomas Hogg's establishment, near the House of Refuge, 

 we called for a moment to look through his Avell filled green-houses, 

 and especially to examine the singular hot water apparatus already de- 

 scribed in this Magazine, vol. II, ]). 248. It is now in steady opera- 

 tion here, and we were equally delighted with its extreme simplicity, 

 the small sjjace occupied by the furnace and boiler, and the evident 

 economy in point of fuel. The water circulates in the most free and 

 perfect manner, which is more than we can say respecting all the differ- 

 ent apparatuses we have seen in this neighborhood. The truth, as Mr. 

 Hogg remarked, is, that in the level system of circulation, care should 

 always be taken that the tube leaving the boiler shall ascend a trifle to 

 the open reservoir, and the return pipe descend towards the boiler, en- 

 tering of course at the bottom. This effectually prevents the accumu- 

 tion of air in the pipe, and, consequently, the gurgling sound sometimes 

 heard in an apparatus not properly laid. 



On looking through the houses, we saw a number of fine seedling 

 geraniums, raised from the rarest varieties the past season, which, from 

 their handsome foliage and thrifty appearance, promise to be valuable 

 sorts. Mr. Hogg is celebrated for his superb collection of this tribe of 

 plants, comprising all the most celebrated European kinds, and the 

 bloom here every spring is quite splendid. We saw also, with pleasure, 

 a number of young plants of the rarer Cape heaths, and a great many 

 pots of seedlings of many Botany Bay plants. A very handsome Ian- 

 tana (L. SellowM,) has been sometime in bloom here, of a fine purple, 

 which we have not seen before in this country. 



Dr. H. S. Moat is, we understand, erecting a very splendid mansion 

 in the Gothic style, in Westchester Country, a few miles from this city, 

 with a very extensive and complete range of hot-houses, stoves, and 

 green-houses. The whole is to be heated by hot water, and constructed 

 after the most approved plans, and the collection of plants, Avhen com- 

 pleted, will probably be one of the first in the Union. Di-. Moat is, -we 

 believe, a gentleman of unlimited means and excellent taste, and we 

 anticipate from him something very creditable in the way of horticul- 

 tural improvement. — A. J. D.
