ber of trees, to say nothing of the great desideratum of 
more rapid growth as a result of the cultivation they 
receive, and the sooner, as a consequence, they may be 
left to themselves. 
“Soils of different localities seem to exercise an im- 
portant influence in deciding the thrift of certain species 
of trees. The amount of moisture in the soil will often 
prove more favorable to one species than to another ; 
more elevation and exposure may be congenial to one 
species and adverse to others.” 
Dr. John A. Warder, to whom we are indebted for 
many instructive facts in connection with tree-planting, 
writes : 
“Tn our northern regions we find the American larch 
and the arbor-vite occupy together very often the low, 
mucky soils of flats and ponds; near them the hemlock 
covers broad flats of low and wet land, with elms and 
black ash, red maples, and other trees of water-loving 
character. Here, in the higher latitudes, we may expect 
to find the native spruces and balsams, while at greater 
elevations, and even on rocky points, with the least 
moisture and soil, the junipers thrive, and on the thin, 
sandy lands large areas will be covered with the gray 
pine on the eastern mountains, while near it, on the 
sandy flats, the white pine forms our valuable forests, 
with the red pine grouped together on its favorite local- 
ities to the eastward. So with the hard-wooded, decid- 
uous trees, each has its favorite locality, where it seems 
best to thrive, though in many places several species 
may have similar habitats, with the result of a mixed 
forest. Thus we often find the sugar maples, white ash, 
hackberry, and some oaks and elms, with wild cherry 
and tulip trees, grouped together. Again, on more 
clayey lands, are the white oak and beech more preva- 
lent, and in wet flats the swamp oaks and sweet gums 
constitute the leading species.” 
The red and black oaks will be found most abun-
