3rd. Cuttings. Shoots of one year's growth are the most proper to be 

 used in this mode of propagating several kinds of forest trees. The shoots 

 should be selected from the most healthy and free-grown branches, and 

 cut into lengths of from six to eighteen inches, according to the kind of 

 tree. If evergreens (a, fig. 3), the leaves should be cut off half way up 

 from the root-end of the cutting (6). Deciduous trees should have shed 

 their leaves before the cuttings (c) are taken from them. The root-ends 

 of the cuttings should be cut finely smooth, and inserted from about 

 a half to three parts of their length into the soil. For every species 

 of cutting, the soil should be light, and composed, at least, of half of 

 fine siliceous sand. There are many species of exotic plants, whose 

 cuttings will only strike root in pure siliceous sand. It need hardly be 

 Fig. 3. remarked, that in this mode of propagating, 



watering is more particularly required to be 

 attended to than in any other. The utility of 

 the sandy nature of the soil consists in its 

 retaining no stagnant moisture, but just suf- 

 ficient for the wants of the shoot during the 

 process of rooting. As soon as the cuttings 

 are well rooted, if in a light soil of the above 

 description, they should be carefully taken up 

 and transplanted to their proper soil ; for 

 although the shoots produce roots more quickly 

 and in greater abundance in the siliceous

growth of the plant after the proper functions 



of the roots begin. Next to that of propagation by seeds, plants may be 

 increased by cuttings more generally than by any other mode: the pro- 

 cess, however, requires more time, skill, and attention, than is demanded 

 for rearing trees from suckers, or by layers or grafting, and it is therefore 

 chiefly practised for the increase of exotic ornamental plants; but the fol- 

 lowing forest trees are most advantageously raised from cuttings :
