Fumigating Plant Houses. — I have often had occasion to observe, that during the process of 

 smoking glass-houses, for the purpose of killing green fly, the men who perform this duty remain 

 in the house to keep, as they say, the coals glowing ; and 

 there they blow away with bellows, or what is more in- 

 convenient, with their own wind-pipes. Having filled 

 the house with smoke, they retire half suffocated. I tried 

 it once after this fashion, but soon had recourse to a sim- 

 ple and more agreeable method, by which I was at once 

 exempt from remaining all the time in the house. A 

 glance at the engraving will best explain the process I 

 adopted. Place four thumb-pots at equal distances in the 

 path of the house; place on these a twelve-inch pot 

 inverted, so that the rim of it rests upon each of them ; 

 then on the top of this place a six-inch pot, with glowing 

 charcoal and tobacco paper, in such a position that the 

 holes may form a communication. As soon as these pots 

 are placed the workman leaves the house, and the draught 

 through the inverted pot is so strong that if the green- 

 house door is left open only for a few moments, the to- 

 bacco would be consumed ; but when it is shut, as it 

 ought to be, the coals remain in a golwing state, and fill 

 the house in a very short time with smoke. According 

 to the size of the house, pots will be requisite at two or 

 more places. Brown's patent fumigator is a very useful 

 contrivance, particularly for pits ; but its being so soon out of order induces me to consider the 

 aboye method, for nurserymen at least^ far superior. — Be7i. — [lliis is a very good plan. — Ed.] —

IIoKTicuLTURAL Societt's Garden, Turnham Green. — One of the most interesting plants at pres- 

 ent in flower here is the Pampas Grass of Brazil, {Oijnerium argenieum), a good specimen of which 

 is growing in the American garden, near its entrance. This plant has 12 flower stems, each some 

 8 feet long, about the thiekneea of thr> thumb, and surmounted by an erect panicle of inflorescence 

 at least 18 inches in length, which beneath bright sunshine looks like a beautiful light-colored 

 feather spangled with silver; the panicle is in the form of that of the beautiful Arundo- phrogmites. 

 The leaves, which are some T or 8 feet long, with a hard flinty skin, grow in tussocks, which, in 

 situations at all favorable, soon acquire a large size ; when in flower, certainly few plants are more 

 striking or magnificent in appearance than this gigantic Grass, which being perfectly hardy, will 

 be found to be a great acquisition to the ornamental grounds of this country. — London Gardeners'
