The method OF Improvement indicated
by these phenomena consists in simply
bringing the river 10 an approximate
uniformity OF width. Reduce the wide
places To u width similar 10 that which
exists al - deep places aud the river

This method involves 10 Strengthening
or shortening of the river as many have
wrongly supposed The whole is
expressed In the simple phrG,r "Givc

in turn will give aunliormity OF velocity,
and this facilitates the discharge Of

vents The cavsHg OF the banks, and there
tore gives stability 10 the improvements
that are placed upon them. The normal
tUllllnllI
to one channel, between Cairo and New
Orleans, In high waters, IS about three
thousand feet. In these parts the
channel at the lowest stages is nowhere
less than thirty ieCt. a reduction Of
the wide parts OF the river 10 three
thousand feet would probably give
twenty-five feet in them at the lowest
water. 1t is needless to say that this
system OF Improvement i not applicable
to the Ohio river. but only to rivers
which flow through alluvial channels.
