come within its purview, and repaid you liberally for your labor,
and the specimens added richly to your collection.
"I will now give you a description, so far as my feeble abilities will
admit, of the things which I think worthy the attention of a devotee of
science. In the first place, the springs are worthy of notice, in a
natural as well as medical point of view. They contain in their
different issues all the different temperatures, from boiling, down to a
pleasure bath. They contain a combining principle, or the quality of
petrifying and uniting various substances that may come in contact with
them, such as flint, earth, stone, iron, &c. The bluff from which they
flow out is principally of an apparent calcareous substance, formed by
the water. In some of the springs a red, in others a green and yellow,
sediment is produced. The waters will remove rheumatism, purge out
mercury, and produce salivation, in those who have it in their system
previously; cure old sores and _consumptions_, in their early stages;
cure dropsies, palsies, &c., if taken in time.
"The next curiosity is the loadstone, a specimen of which I have with
me; you can examine it when you visit this country. The next rock
crystal, of which I have two specimens.[7] The fourth is alum, of which
I procured a small quantity, as I did not visit the cave where it is to
be obtained. The fifth is oil and whetstone, of which there is a great
abundance in that quarter. The sixth is asbestus. In a word, the
subjects are worthy the attention of those who wish to be instrumental
in enlarging or developing that branch of science."

Mr. William Ficklin, one of the pioneers of Kentucky, but now a resident
of Missouri, writes: "I am pleased to hear of your appointment, and wish
I could be with you on the route, as you will visit a section of the
country but little known to our government. I must advise you to be on
your guard against the Indians, the best of whom will murder a man for a
trifle, if they can meet him alone, or off his guard.
"A Mr. Nabb, a few months ago, brought me some white metal, which, he
says, he smelted in a common forge--it was as bright as silver, but too
hard to bear the hammer. I think it must be zinc."
_March 18th_.--Mr. Amos Eaton writes from Troy: "A second edition of my
_Index to Geology_ is in the press--about thirty-six pages struck off. I
have written the whole over anew, and extended it to ab
