The beech, ash, and oak thrive better on a soil of the above 

 composition, than any of the resinous or fir species of trees. 



Of the above varieties of soils, if we except the sandy loam 

 No. 3, and the clayey loam No. 5, there is not one which, on its 

 natural site, could be profitably cultivated under corn or green 

 crops, but which, by skilful planting, might be made to return 

 considerable profits to the owners, and also to the public the many 

 advantages which judicious planting always confers. 



Although there may be found shades of difference in the pro- 

 portions of the constituents of soils receiving the same designa- 

 tion, such, for instance, as the poor sandy soil, containing ten per 

 cent, more or less of sand in one situation more than another, yet 

 the actual produce of timber, all other circumstances being equal, 

 will be found to vary but little, if any. But where the difference 

 in the proportions of the ingredients is found so great as exists 

 between the sandy loam No. 3, and the poor sandy soil No. 2, 

 or, in a wood as between any two of the soils now attempted to 

 be described from practical experience in their culture, as well 

 as from a careful chemical examination of their properties and 

 constitution, a very marked and decisive difference will be found 

 in the comparative produce of timber, and the peculiar species or 

 kinds of trees which should have been planted in the greatest 

 number, or in preference to others.

Of the most approved modes of preparing different 

 Soils, for the Reception of Plants. 



In no improvement of landed property is economy in the 

 first outlay of capital more essentially required than in forest 

 planting. Want of attention to this important point has caused 

 much loss to the country as well as to individuals, it having had 

 the effect of discouraging forest planting generally, and more par-
