the others of the genus, can only be considered as ornamental trees j but in 

 that ciiaracter they hold the first rank ; their delicate acacia-like foliage, and 

 the singularly varied, graceful, and picturesque forms assumed by the tree, 

 more especially when young or middle-aged, together with the singular fea- 

 ture afforded by its spines, will always recommend it in ornamental plant- 

 ations. 



Soil and Situation, Propagation, i^-r. It requires a deep, rich, free soil, and 

 a situation not exposed to high winds; the climate ought, also, to be some- 

 what favourable, otherwise the wood will not ripen ; and it requires the 

 climate of the south of England, or the summers of France, to ripen the 

 seeds. The species is always propagated by seeds imported from America, 

 or from the south of France, or Italy ; for, though seed pods are seldom 

 seen hanging from the trees in the neighbourhood of London, or even in the 

 south of England, they are produced abundantly in various parts of France, 

 even in the neighbourhood of Paris ; and seeds are ripened in fine seasons 

 in Austria. Cobbett directs the seeds to be prepared for sowing by soaking 

 them for 12 hours, as directed for those of the robinia. (See p. 624.) The 

 seeds, he says, when soaked and sown in March, will come up m a fortnight. 

 They are best transplanted to where they are finally to remain when quite 

 young ; as they make but few fibrous roots, and these take, for the most 

 part, a descending direction. The variety (t. t. inermis can only be insured 

 by grafting on the species. In general, however, abundance of plants without 

 S[)ines may be selected from beds of seedlings of G. triacanthos.
