The Larch is unquestionably the most enduring timber 
that we have. It is remarkable, that whilst the red wood or 
heart wood is not formed at all in the other resinous trees, 
till they have lived for a good many years, the Larch, on the 
contrary, begins to make it soon after it is planted ; and 
while you may fell a Scotch fir of thirty years old, and find 
no red wood in it, you can hardly cut down a young Larch 
large enough to be a walking stick, without finding just -such 
a proportion of red wood compared to its diameter as a tree, 
as you will find in the largest Larch tree in the forest, com- 
pared to its diameter. To prove the value of the Larch as a 
timber tree, several experiments were made in the river 
Thames. Posts of equal thickness and strength, some of 
Larch and others of oak, were driven down facing the river 
wall, where they were alternately covered with water by the 
effect of the tide, and then left dry by its fail. This species 
of alternation is the most trying of all circumstances for the 
endurance of timber; and accordingly the oaken posts 
decayed, and were twice renewed in the course of a very 
few years, while those that were made of the Larch, remained 
altogether unchanged. 
Besides the foregoing species, ( Larix Europea,) we have 
two native sorts much resembling it ; which are chiefly
