Progress of Horticulture for 1848. 9 



Such being the fact, why may not the cameUia become 

 eventually a common garden shrub, at least as far north as 

 Philadelphia ? At another time, we shall recur to the remarks 

 of Dr. Lindley again, and give the facts which he adduces, 

 relative to the temperature, soil, &c., of the climate of China, 

 — and the best means of accomplishing successful naturaliza- 

 tion. 



We are led to these remarks, from having recently seen a 

 fine plant of Buddies Lindleyd^a, one of Mr. Fortune's dis- 

 coveries, near Shanghae, which stood out last winter, without 

 protection ; though only a young plant, set out in the spring 

 of 1817, and making but a slender growth, the root was un- 

 injured, and, when we saw it in September, it had thrown up 

 shoots, five feet high. We have no doubt, that, in a light soil, 

 where the growth would be checked early, and the wood per- 

 fectly ripened, it will be found quite hardy. The Ailantus, 

 a well known hardy tree, from China, is only hardy under 

 certain conditions of soil and locality. Last winter, we had 

 one half of a long row of these trees, which were killed both 

 root and branch, while the other half remained uninjured. 

 The trees stood upon a piece of ground, on a side hill ; and 

 part of the row sloped into a hollow, where the water was 

 confined, after heavy rains ; the consequence was, that all 

 the trees, around which the water stood and froze, were 

 killed; while those from which the water drained away, 

 were alive to the points of the shoots. It will thus be seen, 

 that, in the naturalization of plants, much will depend upon a 

 knowledge of their natural habits, and the soil and situation 

 in which they grow. Success must not always be expected, 

 at first. One failure should not discourage the ardent culti- 

 vator ; but, where climate, and the nature of the plants, lead 

 us to suspect their hardiness, experiments should be repeated, 

 till they remove all doubts. 



Arboriculture. 



A great and increasing interest has been manifested in the 

 subject of Arboriculture ; and it is gratifying to find our agri- 

 cultural societies, aided by the liberality of gentlemen of 

 wealth and taste, encouraging the cultivation of forest trees.
