it .produces in its uncultivated state are very 
poor, sour, and but little larger than fine cur-

The variety of trees found in the forests of 
Canada is prodigious, and it is supposed that 
many kinds are still unknown: beech trees, ' 
oaks, elms, ashes, pines, sycamores, cliesnuts, 
walnuts, of each of which several different spe¬ 
cies are commonly met with ; the sugar maple 
tree is also found in almost every part of the 
country, a tree never seen but upon good 
ground. There, are.two kinds of this very va¬ 
luable tree in Canada; the one called the 
.swamp maple, from its being, generally found 
upon low lands; the other, the mountain or 
curled maple, from growing upon high dry 
ground, and from the- grain of the wood being 
very beautifully variegated wills little, stripes 
and curls. The former yields a much greater 
quantity of sap, in proportion to its size,- than 
the other, but this sap. does not afford,so .much 
sugar as that of the curled maple. A pound of 
sugar is frequently procured from two or three 
gallons of the sap of the curled maple, 
whereas no more than the same quantity cap 
be had from' six or seven gallons of that of 
the swamp. 
The most approved method of getting the 
sap is by piercing a hole with an auger in the
