at any time to refer back and ask if we have recommended any invention 

 or appliance in horticulture, or any plant, new or old, -which has not 

 proved equal to our commendations. So in regard to these Paxton houses. 

 We have seen them in operation, and taken note of every detail of their 

 construction ; and we say without hesitation that, for simplicity, portability, 

 and efficiency for the practical pursuit and enjoyment of horticulture, they 

 are of unquestionable excellency, and they place the horticultural public 

 in a position of obligation to Sir Joseph Paxton, as having wrought into 

 practice an original and ingenious idea. The span-roofed houses average a 

 trifle over £ 1 per foot run, and the lean-to's 10s. per foot run. This includes 

 water- troughs and ends complete, but not the heating apparatus. A span- 



house of thirty-one feet three inches in length, with twelve-feet lights, 

 will cost £53 ; with ten-feet lights, £42 5s. ; and with eight-feet lights, 

 £33. The greater the length, the less is the average per foot ; as, for 

 instance, a house 105 feet 11 inches, with eight-feet lights, costs £97 15s., 

 which is about 18s. 6d. per foot; but a house twenty feet seven inches, 

 with eight- feet lights, costs £24, which is £1 4s. per foot. Lean-to 

 houses vary in the same way. A lean-to, 105 feet 11 inches, with eight- 

 feet lights, costs £48 7s. 6d. ; but one of twenty feet seven inches amounts 

 to £12. The fullest particulars respecting these patent houses may be ob- 

 tained on application to the manufacturer, Mr. S. Heremann, at his office, 

 7, Pall Mall East, where a model of one may be seen. 



"We are indebted to the fanciful ingenuity of Mr. Donald Beaton for a 

 very appropriate name for a new horticultural contrivance. "Crinoline 

 pots " are, so far as we know, in use only at the garden of A. Mongredien, 

 Esq., at Forest Hill, where Mr. Summers, the stepfather of Spergula 

 pilifera (Mr. Mongredien himself being the original introducer of it), gives 

 so favourable an account of them that we cannot suppose they will long- 

 continue inaccessible to the general public. These crinoline pots are, as 

 shown in the engraving, constructed wholly of galvanized wire, and if 

 filled with fine sandy compost of a friable nature, the greater part would 

 run out through the wires, and the pots would bo of no use at all. Put if 

 filled with lumps of turfy peat, and trimmed up neatly, the soil holds to-
