148 LANDSCAPE GARDENING. 



troduced into any part of the grounds. When but a limited 

 extent is devoted to a lawn or garden, this tree should be 

 among the first to obtain a place ; as one or two Three-thorned 

 Acacias, mingled with other larger and heavier foliage, will at 

 once produce a charming variety. 



The Three-thorned Acacia has been strongly recommended 

 for hedores. It is too liable to become thin at the bottom, to 

 serve well for an outer enclosure, but if kept well trimmed, 

 it forms a capital farm fence and protection against the larger 

 animals, growing up in much less time than the hawthorn. 

 Like the locust, it has the disadvantage of expanding its fo- 

 liage late in the spring. In the strong rich soils, which it 

 prefers, it grows very vigorously, and is easily propagated 

 from seeds. 



The Three-thorned Acacia, (G. triacanthos^) is the prin- 

 cipal species, and is indigenous to the states west of the 

 Alleghanies. G. monos'perina is another kind, which is 

 scarcely distinguishable from the Three-thorned, except in 

 having one-seeded pods. The seedlings raised from G. tri- 

 acanlhos, are often entirely destitue of thorns. 



There is a fine species called the Chinese, [G. horrida,) 

 with larger and finer foliage, and immense triple thorns, which 

 is interesting from its~ great singularity, A tree of this kind 

 which we imported, has stood the three last winters perfectly 

 uninjured, and promises to be beautiful and very hardy. 

 Some noble specimens of the common Three-thorned Acacia, 

 may be seen upon the lawn at Hyde Park, the fine seat of 

 the late Dr. Hosack.
