I. THE PINES. 49 
of other products, several species of pines may be planted or 
are found growing naturally with an approach to luxuriance. 
They will even take root and flourish among the moving sands 
exposed to the sea-breezes, thereby fixing these sands, and re- 
deeming to the use of man, tracts otherwise destined to perpet- 
ual sterility. 
The root of the pines is generally woody and irregularly ram- 
ified, and remarkable for its toughness and durability.* It never 
descends to a great depth, but spreads horizontally, to no great 
distance, near the surface. It is short and small, in comparison 
to the size of the tree, in this respect resembling that of the 
palms. In consequence of this peculiarity, most of the pines 
are uprooted by high winds, while the deciduous trees are bro- 
ken off near the ground. In the winter of 1839—’40, I had an 
opportunity of examining the roots of a very large number of 
various species of pine which had been uprooted by the vio- 
lent gale of the previous November, and I found that, in every 
case, they spread to a very inconsiderable distance, just below 
the surface of the ground. In old trees, of several species, par- 
ticularly the white pine, the swollen roots appear above the 
ground to some distance from the trunk. In no instance, except 
in the anomalous case of the Southern cypress,y are suckers 
thrown up from the root; and only in the pitch pine have 
shoots been observed to spring from the stump. 
Most of the plants of this family are trees of an erect, straight, 
cylindrical trunk, often of great size and height. In some, as 
the hemlock, the yew and the ginkgo tree, the branches have no 
regular order, but in most, and especially in the firs and pines, 
they are disposed circularly, in imperfect whorls, around the

+ There is a striking peculiarity in the roots of the Cupressus disticha (Taxo- 
dium) of our southern states. This tree grows naturally in low grounds subject 
to annual inundations, in which situation it rises sometimes to the height of 120 
feet, with a diameter at base of 25, 30, or even 40 feet. The roots, which run 
horizontally at a short depth below the surface, throw up conical, rounded protu- 
berances, sometimes 4 or 5 feet high, but usually much smaller, smooth without 
and hollow, looking not unlike mile-posts, and remaining always naked, These 
may be observed, on a small scale, about the base of the magnificent cypress in 
Bartram’s garden near Philadelphia.
