I have often heard the reports of guns very plainly that were fired
at ducks on Detroit River, six or seven miles away. With what velocity
their sounds approached me, I leave Dr. Derham to determine. According to
his calculation it must have been at the rate of eleven hundred and
forty-two feet per second. It has also been ascertained with what
velocity the ball leaves the gun and pierces the air. The following is
the practical result ascertained by the experiments of Mr. Robins, Count
Rumford, and Dr. Hutton: "A musket ball, discharged with a common charge
of powder, issues from the muzzle of the piece with a velocity between
sixteen and seventeen hundred feet in a second."

HOW I GOT IN TROUBLE RIDING IN A CANOE.
I often rode in my canoe when I did not go fishing. I took one ride in it
that I shall always remember, at least the remembrance of it has forced
itself upon my mind a number of times, in the days gone by, and I expect
to think of it a few times more. Of course my oldest sister, Rachel, who
is now Mrs. Crandell, of Dearborn, became acquainted with the young
ladies of the neighborhood.
