The improvement of the Mississippi River near St. Louis progresses
satisfactorily. The efficacy of the jetty system is illustrated in the
lines of mattresses which showed accumulations of sand deposits ranging
from the surface of the river to nearly sixteen feet in height. At Twin
Hollow, thirteen miles from St. Louis and six miles from Horse-Tail Bar,
there was found a sand bar extending over the widest portion of the
river on which the engineering forces were engaged. Hurdles are built
out from the shore to concentrate the stream on the obstruction, and
then to protect the river from widening willows are interwoven between
the piles. At Carroll's Island mattresses 125 feet wide have been
placed, and the banks revetted with stone from ordinary low water to a
16 foot stage. There is plenty of water over the bar, and at the most
shallow points the lead showed a depth of twelve feet. Beard's Island, a
short distance further, is also being improved, the largest force of men
at any one place being here engaged. Four thousand feet of mattresses
have been begun, and in placing them work will be vigorously prosecuted
until operations are suspended by floating ice. The different sections
are under the direction of W. F. Fries, resident engineer, and E. M.
Currie, superintending engineer. There are now employed about 1,200 men,
thirty barges and scows, two steam launches, and the stern-wheel steamer
A. A. Humphreys. The improvements have cost, in actual money expended,
about $200,000, and as the appropriation for the ensuing year
approximates $600,000, the prospect of a clear channel is gratifying to
those interested in the river.
