to quote the statement of an able and

contained in the following:
REPORT.
To Messrs. May and Cover, Proprietors
of the Water Power at Cedar Bluffs,
Cedar County, Iowa.
In response to your request for me to
furnish you, in advance of my report
IA few OF the leading facts-attailable
head, horse power, &c, of the Cedar
River at Cedar Bluffs, Cedar Co., Iowa,
IL approximately ascertaintd by sur
vey made by myself during the last
week of June and the first OF July last,
! have the honor TO submit to you the
following brief atements Of the facts:
Cedar River ut Covers Ferry, in
Cedar County, just opposite the village
Of Cedar Bluffs, had at the time made
the survey, "a mean width of 45S fee;
and mean depth of $50 feet, indica-

Rock, point some y or three miles
above the ferry, To the Ferry, the river
! has fall of y feet, but the head at
tainahe by the construction of weir oil
dam cannot be far from feet
consequently the available mechanical
effect of the river at a stage of wate
showing mean depth at the Ferry o
$40 feet, rs ut the time of my observa
ton will be rs above 23S4 IL. L.
OF course all OF this mechanical eiiec
cannot be utilized. Some is lost by
teakage: more by imperfect Wheels
Perhaps SD per cent, possibly 50 pei
cent might be utilized.
The best vertical wheels utilize som.

some of the improved turbines utiliz.

tons from which to spring rock weir
but good material, most conveniently 10

In conclusion, gentleman, allow nj

hesitancy in saying that in the Ceda,
River, in:Ceiar Bluffs, Iowa, you have

All of which is most respectfully sub

From this report 1t well be seen tina
ut Il low stage Of water there is a sutii
ciout loo,rer for doing the work which
if required to be done by animal power
would require a great number, aye
M4us6mda, The power estimated Il.
necessary to drive one run OF four foot
French Burr Mill Stones, is twelve
horse power, and here at a loW stage OF
water, there is sufficient power to propel
more than $50 run or its equivalent in
other machinery and much of the year
probably more than double that amount
1t IL difficult to present to the mind the
real Ediue OF thu water power to the
sfyty-five thousand inhabitants within
