Btiffest clay, or the most friable loam; others perti- 

 naciously cling to a particular soil, and refuse to flour- 

 ish in any other. Some refuse to grow in any but

 the heavy, moist, and clammy earths contiguous to 

 water. All these qualifications must be regarded, to 

 insure success in diversified plantations. 



In "pleasure-grounds," exotic trees, of character 

 congenial with the soil and climate, may be sparingly 

 introduced ; as, the horse-chestnut, the weeping wil-

 be occasionally thrown the Lombardy-poplar — a tree 

 often treated with idle abuse because it has some 

 faults ; but no one can say, and say it truthfully, that

 trees, does not give both a graceful and picturesque 

 expression to the landscape, which would be wanting 

 without it. The larch may partially supply its pres- 

 ence, but not with entire effect. Excessive use of the 

 poplar, in some instances, has brought it into, per-
