Indian country the ensuing fall."

ROTARY SAILS.--John B. Perrault, whose name has been before mentioned,
invented a novel boat, to be propelled by the force of rotary sails
acting on machinery, which turns paddle-wheels; a very ingenious thing.
The result of experiments is, however, unfavorable to its
practical adoption.

HOSTILITIES BETWEEN THE SIOUX AND CHIPPEWAS.--These hostilities have
reached such a point, that the department has deemed it necessary to
interpose its friendly offices in a more formidable manner, by
dispatching an expedition into the principal seat of the war. The
instructions, however (of Aug. 9th), by which I was designated for that
purpose, reached me so late in that month, that it was not deemed
practicable to carry them into effect until the next year. I reported
the facts, which are deemed necessary to be known at head-quarters, in
order to give efficacy to this necessary and proper measure,
recommending that the expedition be deferred, and that, in the meantime,
suitable means be provided for making it, to the greatest extent,
effectual.

FRIENDSHIP AND BADINAGE.--A friend writes from Detroit (Aug. 14th): "For
a brief space, that is, about a quarter of an hour, I can borrow a
little use of my own soul, though I cannot call it exactly my own. You
will not fail to note, I trust, how eminently judicious is the
appropriation.

"A few days since, the letter containing the notice of your appointment
to the Lake Superior destination, was mailed for you. The purpose of
this is to suggest the memory of your doubtful promise, to come down in
the fall for the winter session. The Gov. thinks it too late in the
season to attempt your expedition this fall; and I presume, that it is,
I hope, your papers will not reach you in time to leave this summer, an
opinion of questionable correctness.

"You can have your table placed in the corner, and amuse yourself with
preparing an article for the _N.A._, Thus you will discharge a double
duty to your country; one to its political interests, and another to its
department of letters. Whatever preparations are necessary at your
place, can be made in the winter, under directions left there when you
come down, and such as could be more conveniently made here, you shall
have every aid in forwarding. The fact is, I see not a single objection,
I _cannot_ see one, and more than that, I won't. This I conceive to be
the only rational view to be taken of
