It has
been ascertained what is the area of the cross section of this stream and
the area of the face of the piers, and the engineers say that the piers
being put there will increase the current proportionally as the space is
decreased. So with the boat in the draw. The depth of the channel was
twenty-two feet, the width one hundred and sixteen feet; multiply these
and you have the square-feet across the water of the draw, viz.: 2552
feet. The Afton was 35 feet wide and drew 5 feet, making a fourteenth of
the sum. Now, one-fourteenth of five miles is five-fourteenths of one
mile--about one third of a mile--the increase of the current. We will
call the current five and a half miles per hour. The next thing I will
try to prove is that the plaintiff's (?) boat had power to run six miles
an hour in that current. It had been testified that she was a strong,
swift boat, able to run eight miles an hour up stream in a current of
four miles an hour, and fifteen miles down stream. Strike the average and
you will find what is her average--about eleven and a half miles. Take
the five and a half miles which is the speed of the current in the draw
and it leaves the power of that boat in that draw at six miles an hour,
528 feet per minute and 8 4/5 feet to the second.
