ternatives which present themselves for con
sideration It is true that the last alternative
is not without qualification, as will be seen
further on, when the diversion of some of the
tributaries of the Sacramento is considered.
Il is to be remarked that this diversion is in
itself destructive to our navigable line and
that it does not afford relief to the city u
Marysville and to the farming lands adjoin-
ing the mining rivers, which are now SC
seriously threatened.
HOW THE DAMS NAY BE MADB.
The purpose of these dams is novel. The
mining dumps, however, in the rivers where
the material is large, as at Smartsville, play
the same part, and store material above
them. The security of these dams depends
upon the stability of the lower slope. The
stones ON these slopes must be so large as to
hold their places under the floods which pass
over them, and the positions they are made
to take must be of studied irregslarIty SO as
to destroy velocity by falls.
The first dam OF the series Is the most i'm
portant, and viii require the most particu
lar care III its contraction.
The cost of these dams it must be admitted,
cannot at present be closely forecast. The
prices that have been assumed are much in
advance If those thai are given by good

TREATMENT OF BEAR AND AMERICAN RIVERS.
The Bear river requires almost identical
treatment with the Yuba. It ought to have
a lam at some point in the mountains. This
river has not been examined with the same
care as the Yuba, and therefore an estimate
cannot be made with the same detiniteness A
second dam ought to be built at the edge of
the plain near Camp Far West.
The same treatment is required for the
American river.

Il is strongly recommended that these dams
be built during the coming summer. The
proper time is during low water, which ex-
tends IRON August to October. During this
period there is little water in these rivers. ex-
cept that which comes from the ravines. and
consequently there will be little difficulty
due to the presence of a strong current
At the dam site in the Yuba, near the
mouth of Deer creek. the rise of high water
is stated to be IL OF II feet, The freshets are
generally Of short duration in the winter, the
greater part of the precipitation being in the
form of snow. A second high stage lasts
through Nav and June, during which time
the snow is melting. This latter stage is be-
lieyed to be not so high as the winter fresh
cts. although much longer.
The storage of mining detritus in the
mountains being successfully disposed of, the
future will probably be relieved from the i'm
mense accretions of sand that now escapes
yearly from the mines. This is an immense
advantage. But it remains to point out an
other source that is omen for the further pro-
lection of the Sacramento river. The full
investigation of this plan as to its cost and
probability of proportionate benefit, will
have to be left for future occasion.
