CAMPANULA PYHAMIUALIS. 65 



and screw it down to a rather gentle pressure for about three days. 

 (I have the press in a dry room.) I then dry the paper, regulate any 

 derangement in form of the specimens, and replace them in the press 

 and give it a tighter pressure. In a few days I again dry the paper 

 and flannel, and by that time most kinds are properly dried ; except tlie 

 succulent tribe, which require a longer time, and in preparation a less 

 degree of pressure, or the colours will be changed. Before I phice 

 them in the Herbarium, I take a camel-hair brush and wash them 

 wholly over both sides with a solution of one pint of spirits of wine, 

 and two drachms of corrosive sublimate, to which I add a small piece 

 of bruised camphor. This preserves them from injury by the moti), 

 &c. After they are dried I secure them in their assigned places with 

 gum-water and strips of tlie edges of postage stamp sheets. 



CAMPANULA PYRAMIDALIS. 



At a meeting of the Croydon Gardeners' Society, Mr. Clarke con- 

 tributed some remarks upon the cultivation of the Chimney Campanula 

 (Campanula Pyramidalis), which he considered to have been much 

 neglected, from the frequent introduction of new plants, in many- 

 instances much inferior to old ones of the same family ; and as a means 

 of aiding its re-admission to the green-house, said : " My method of 

 growing this plant is, to sow the seed in March on a slight hot-bed ; 

 when they have made two or three leaves, pot them off into three-inch 

 pots, and place them in a close frame till they have made growth, then 

 harden them off by degrees, and they will have filled their pots by May. 

 Prepare a good rich piece of ground in an airy situation, and plant 

 them out 18 indies apart; let them remain till the following March, 

 by which time they will have made good growth ; take them up with 

 good balls of earth adhering to them, and pot tliem in 15-inch pots, 

 using the following compost : — equal parts of well decomposed horse- 

 dung, turfy loam, and leaf-mould, with a portion of silver sand, and 

 good drainage. Place them in a frame or pit, which keep closed until 

 they have made growth, shortly after which they will open their flower 

 stems ; as they advance keep them as close to the glass as possible, 

 admitting a large portion of air through the day. As the spring 

 advances, frequently syringe them, closing the pit with a liumid atmo- 

 sphere in the afternoon. When their flower stems have attained too 

 great a height for the pit or frame, remove them to the green-house or 

 conservatory, placing them where they can receive a large portion of 

 air. By giving this old plant the treatment here detailed, it will pro- 

 duce flower stems measuring from 10 to 12 feet high. I am not 

 acquainted with any plant more easy of being cultivated to perfection, 

 or more useful for halls, verandahs, &c., when thus cultivated, as from 

 the substance of its flowers it is capable of keeping in flower much 

 longer, and can endure many situations which the majority of flowers 

 cannot. I have seen it trained to fan-sliaped frames, and in the pleasant 

 summer months, when fire is not required, placed in front of the grate, 

 and hence, as I presume, its name, Chimney Campanula." — Mr. Agate 

 said he could not flower the plant to his satisfaction until he turned it
