Cumberland river, shove she mouth Of
Stones river.
3. A careful cross-sec;iOning Of the sur
face Of the knob with view to obtaining
its exact shape, in order to estimate accu-
rately the cost of building reservoirs
T. 4 thorough examination Of the valley
OF stones river from its mouth to point
some distance above the railroad bridge, to
determine the feasibility Of using it as a
water power t0s pumping the water to the
proposed reservoir.
The last named examination developed
the following facts:
I. An exceedingly favorable point exists
about ore mile below the Lebanon turn
pike bridge at which TO construct a dam
across Stones river. the water to i'e carried
thence through the lads of Mr.. DObsOn by
a short tunnel or canal. and thence By race
way to the proposed pump-hOuse, just abo9e
the mouth of Stones river. This dam
would be about eco feet long to the high
land on each side and not less than fifty
feet hieh above the bed of Stones river, in
order 20 obtain such an elevation as would
place it above the back water Of Cumber-
land river.
?. The result of such q data
would be 10 overflow permanent
IL not less than 1000 acres Of
valuable land IN the valley Of Stones river.
Many dirt roads would be entirely closed
and the LebailUn turnpike, and the David
son and Wilson counties iurnpikcs, would
each be overlooked to considerable sStent.
$. For large portion Of the year Stones
ri er has probably sufficient supply of
water to run enough turbines to fill your
proposed reservoirs. During the summer
months however il could not be relied up
on. In August. September and October of
this year, the water would most OF the
time have easily passed through II inch
pipe with sluggish flow.
This last fact ] deemed sufficiently con
elusive to justify. me in abandoning the
idea Of using stones river as a water power.
The estimates which follow ere based up
on the following named items.
!. A first-elaSS steam pumping engine,
capable Of raising six. million gallons of
water, $50 feet high in twenty-fOur hours. |
? A receiving reservoir Of capacity of
three million gallons.
3. A storing or distributing reservoir Of
capacity Of ten million gallons. All the
water to be pumped into the smaller reser-
voir and to pass thence through filters 10
the larger and lower reservoir and thence |
20 the city.
). The necessary bitches, entertainments, |
aqueducts and culverts to place this main |
pipe permanently and securely in position. |
The shape of Todd's Knob is such that |
the reservoirs can be enlarged whenever the !
necessities of the city require it, without |
in anv manner disturbing those which it is
now proposed to build. The upper and /
smaller reservoir may be extended TO hold /
100000 gallons, and the larger and lower
one may be made to contain 100000
gallons,
The elevation of the lower or distributing
reservoir will be such that after making all
due allowances for friction, etc, the water
will flow at all times ten feet above the
apex of the roof Of the Capitol.
The pressure in the pipes in the lower por-
lions of the city will be 14I pounds to the
square inch.
