e world over.
Before it, _Bruce's Mineralogical Journal_, though continued but for a
few years, was eminently scientific, _Cleaveland's Mineralogy_ has had
the effect to diffuse scientific knowledge not only among men of
science, but other classes of readers. In ornithology, in conchology,
and especially in botany, geology and mineralogy, American mind has
proved itself eminently fitted for the highest tasks.

A REMINISCENCE.--When I returned from the West to the city of New York
in 1819, Mr. John Griscomb was a popular lecturer on chemistry in the
old almshouse. He apprised me that the peculiar friable white clay,
which I had labeled chalk from its external characters, contained no
carbonic acid. It was a chemical fact that impressed me. I was reminded
of this fact, and of his friendly countenance, ever after, on receiving
a letter of introduction from him by a Mr. William R. Smith, with three
volumes of his writings (28th May). I am satisfied that we store up the
memory of a kind or friendly act, however small (if it be done in a
crisis of our affairs), as long as, and more tenaciously than, an
unkind one.

VOYAGE INLAND.--At length, all things being ready, I embarked at the
head of the portage of the St. Mary's, and proceeded to the small sandy
plain at the foot of Point Iroquois, at the entrance into Lake Superior,
where I encamped. To this point I was accompanied by Mrs. Schoolcraft
and the children, and Lt. Allen and the Miss Johnstons, the day being
calm and delightful, and the views on every hand the most enchanting and
magnificent. While at Detroit during the winter, I had invited Dr.
Douglass Houghton to accompany me to vaccinate the Indians. He was a man
of pleasing manners and deportment, small of stature, and of a compact
make, and apparently well suited to withstand the fatigues incidental to
such a journey. He was a good botanist and geologist--objects of
interest to me at all times; but especially so now, for I should have
considered it inexcusable to conduct an expedition into the Indian
country, without collecting data over and above the public duties, to
understand its natural history. I charged myself, on this occasion, more
particularly with the Indian subject--their manners and customs,
conditions, languages, and history, and the policy best suited to
advance them in the scale of thinking beings, responsible for their
acts, moral and political.
