nside of the cavity, so that it could not possibly be
pushed out, the force of expansion split the shell. The amazing force of
expansion is also shown from the distance to which these iron plugs are
thrown out of the fuse-hole. A plug of two pounds and a half weight was
thrown no less than 415 feet from the shell; the fuse axis was at an
angle of 45 deg.; the thermometer showed 51 deg. below the freezing point. Here
you see ice and gunpowder performing the same operations. That similar
effects should proceed from such dissimilar causes is very
extraordinary."--Gray's _Canada_, p. 309.]

[Footnote 165: "In Europe, in Asia, in Africa, and even in South
America, the primeval trees, however much their magnitude may arrest
admiration, do not grow in the promiscuous style that prevails in the
general character of the North American woods. Many varieties of the
pine, intermingled with birch, maple, beech, oak, and numerous other
tribes, branch luxuriantly over the banks of lakes and rivers, extend in
stately grandeur along the plains, and stretch proudly up to the very
summits of the mountains. It is impossible to exaggerate the autumnal
beauty of these forests; nothing under heaven can be compared to its
effulgent grandeur. Two or three frosty nights in the decline of autumn
transform the boundless verdure of a whole empire into every possible
tint of brilliant scarlet, rich violet, every shade of blue and brown,
vivid crimson, and glittering yellow. The stern, inexorable fir tribes
alone maintain their eternal somber green. All others, in mountains or
in villages, burst into the most glorious vegetable beauty, and exhibit
the most splendid and most enchanting panorama on earth."--M'Gregor, p.
79, 80.

Mr. Weld says, "The varied hues of the trees at this season of the year
(autumn) can hardly be imagined by those who never have had an
opportunity of observing them; and, indeed, as others have often
remarked before, were a painter to attempt to color a picture from them,
it would be condemned in Europe as totally different from any thing that
ever existed in nature."--Weld
