upon the unwise policy of not Harvesting /
power for good that has shown itself capable /
unchecked, OF doing much harm.
Then again is not this only theory, II
the creek was properly dredged is it not
probable that it would remain so. The
answer is No. 1t will not maintain uniform
depth after being dredged and for one
reason the altitude Of water at the side not
being equal to what it Is in the centre nee.
essarily reduces the face Of the current
las any one can see who looks at a moving
stream that nearest the shore being shallow
move: the slowest,) and herein lies the
| chief cause why shoals form so rapidly,
| namely, from \ decreased depth of water
at the sides, slow moving current in com
! parisOn to the cSntre, and the inevitable
deposits at the sides, and then the shelving
from the sides to the centre, and lastly the
barrier across which by way of mitigation
is called a shoal.
That this is not conjectural theory,
| will give an illustration that occurred in
practice, also that what has been referred
to has actually happened. It devOlved on
the writer, fortunately or otherwise. to de.
sign the brig OtioriHa from the dimensions,
built some or 7 years ago at the Lending.
The vessel being intended for of shore
trade was much sharper vertically than was
usally built then. On the model being
completed and the launching line taken, it
was found it would require at least feet
OF water to float her out. At 100 yards to the
south OF where 1t was proposed TO build the
vessel, there was on Temples bar, just
| Is inches to meet and receive this enormous
bulk. 1t was at the time suggested to the
builders to construct the vessel on the line
of Leipsic Creek with its uniform channel
of 10 feet of water; but no, this Creek
should have the honor, and we did have il,
hut at cost Of $1,000 TO get the vessel to
Philadelphia; from Leipsic it would have
been about $50. There was depth dug for
on Temples bar Of feet. this Hoated the
vessel over she drawing when launched.

lower shoals had hut maximum depth of
% to 6 feet. We had to dig upon all, and
, today were is the once feet on Temples
tar, the sounding rod would show that it is

that length of time but had that bar been
jettyed like two marsh banks ii would not
have shOaled thus, but instead the attitude
