346 Foreign JSTotices. 



was read by Mr. Judil, on the forcing of roses, from which we make 

 the following extracts: 



Mr. Juilfl divides them into two classes, China and noisette, and moss 

 and Provins roses. China and noisette roses he cuts down at the end of 

 September; shakes most of the soil from the root; re-pots them in fresh 

 compost, consisting of equal propoJtions of peat earth, leaf mould and 

 good loam, with a portion of sand and a little soot; and places them in 

 a cold pit till the beginning of November, when he removes them to one 

 having the command of fire heat; gives them a temperature of from 55° 

 to 65^; waters in the afternoon; syringes after a sunny day, being care- 

 ful not to allow the plant to be long damp, as it renders them liable to 

 mildew. These will flower in the end of January; and, hardened off, 

 will flower in the green-house till May. A second stock, put in in Jan- 

 uary, will flower from May to August; those put in in the green-house 

 in January, cut down and re-potted in May, will flower in August; take 

 the place of those put in the conservatory in May, which, now cut 

 down, (October,) will be ready for forcing in November. Mr. Judd at- 

 taches great importance to watering and syringing in the afternoon; 

 contending that doing it in the morning takes oft' that fine dew, so bene- 

 ficial to the plant, which, no doubt, containing a portion of gaseous mat- 

 tor, becomes absorbed by the leaves when the sun shines upon them. 



For forcing moss roses, Mr. Judd recommends two-years-old layers; 

 and for Provins, good suckers or plants, taken up and potted in the 

 month of September, into a compost, consisting of two-thirds good 

 loam, and one-third rotten cow dung with a portion of sand and soot. 

 He then places them, in October, in a frame or pit, with a sweet bottom 

 heat of from 90'^ to 100^, and an atmospheric temperature of from 50^ to 

 55°, increasing it gradually to 65^, and they will flower in January, 

 when a second stock commenced with w ild flowers in April. When 

 they have done flowering, they must be hardened off" before exposure; 

 planted out, or well supplied with water in their pots, so as to have 

 the buds well perfected; to effect which, the first stock should be prun- 

 ed in August. He also recommends having moss and Provins roses es- 

 tablished in pots, and laid down eveiy season, applying the heat by 

 dung linings. For the destruction of the aphis, he recommends tobacco 

 sinoke; for destroying grubs, pinching off" by hand; and for eradicating 

 mildew, sprinkling with flour of sulphur. 



A discussion arose between the members upon this article, the sub- 

 stance of which is as follows: — 



Mr. Fish considered that, by the method proposed, China roses might 

 be kept flowering all the year. He agreed in the propriety of watering 

 in the evening, but did not see the justice of the reasons assigned for it. 

 The existence of moisture on the surface, and the drops hanging on the 

 accuminated points of the leaves in the morning, were a sign of health, 

 and an evidence that the plants required no syringing at any time; 

 but he had seen no prejudicial effects from syringing at any time, pro- 

 vided the glass over the plants was good and free from spots. He did 

 not think any evidence had deen adduced to show that the moisture on 

 the leaves, when not a secretion, consisted of a gaseous matter, except 

 the constituents of water; or that the moisture was absorbed into the 

 system by any agency of the sun-beams, and not rather evai)orated in 

 the atmosphere of the house. He mentioned that beautiful edgings to 

 flower-borders might be made by China roses tied down to a low trellis. 

 He agreed that, by the system of forcing roses at once, instead of having 

 the plants previously prepared, roses would be got, but doubted much 

 if with equal success; and that, as ])hysiology had been introduced, he 

 could not place the one system on an equality with the other, if he took 

 the principles of that science for his guide. 

 Mr. Caie drew a distinction between China and noisette roses, show-
