They succeed best where the soil is of the peaty or moory kiiul, 

 and where it has not been enriched by manure; and as they protrude 

 their roots chiefly near the surfVice, it shouki be as httle dug about 

 them as possible. 



The four following sorts may be increased in the same manner as 

 the former; but the best practice is by layers, cuttings, or slips, 

 which should be laid down or planted out in pots filled wilh boggy 

 earth, either in the early spring or the latter end of summer, plunging 

 them in a moderate hot-bed, giving them proper shade and water. 

 When they have taken full root, they should be removed wilh balls 

 of earth about them into separate pots, being replaced in the hot-bed 

 till they become well established, when they will be capable of bear- 

 ing the open air in mild weather. 



All the other species may be increased either by cuttings or layers, 

 but most of them by the former. The cuttings should be made from 

 the best young shoots, and be planted in the spring season in pots 

 filled with a composition of light boggy and loamy earth, being 

 placed in the hot-bed, and covered with bell-glasses, and duely 

 shaded from the sun, slight waterings being given when necessary; 

 the layers are best made in the autumn, being managed in the same 

 way. 



When the plants are perfectly rooted, they may be removed into 

 separate pots filled with the same sort of earth, and placed in the 

 dry, stove or green-house, where many of the plants nmst constantly 

 be kept. 



The ninth, twentieth, and twenty-sixth species must, however, be 

 raised by layers, as they have not yet been increased by planting 

 their cuttings. 



When seeds are made use of in producing these plants, they 

 should be sown in pots filled wilh the above sort of earth, in the 

 early spring, and plunged in the hot-bed of the stove. When the 

 plants have acquired a few inches growth, they should be removed 

 into single pots with a little earth about their roots, and be rcplungcd 

 in the hot-bed in the stove, being preserved in it, or the warmest 

 part of the green-house, during the winler.
