[361] "The boats are fitted," says Captain Hall, "with what is
called a snag-chamber;--a partition formed of stout planks,
which is calked, and made so effectually water-tight that the
foremost end of the vessel is cut off as entirely from the
rest of the hold as if it belonged to another boat. If the
steam-vessel happen to run against a snag, and that a hole is
made in her bow, under the surface, this chamber merely fills
with water."--Travels in North America, vol. iii. p. 363.

[364] Trees submerged in an upright position have been observed
in other parts of N. America. Thus Captains Clark and Lewis
found, about the year 1807, a forest of pines standing erect
under water in the body of the Columbia river, which they
supposed, from the appearance of the trees, to have been
submerged only about twenty years. (Travels, &c. vol. ii. p.
241.) More lately (1835), the Rev. Mr. Parker observed on the
same river (lat. 45 degrees N., long. 121 degrees W.) trees
standing in their natural position in spots where the water was
more than twenty feet deep. The tops of the trees had
disappeared; but between high and low water-mark the trunks were
only partially decayed; and the roots were seen through the
clear water, spreading as they had
