: -
Abont two weeks since an indivldual-Mr.
Riddle called upon me to obtain my services
in making survey with view of finding
new and cheaper route 10 bring the waters of
Clear Creek upon Olney and Intermediate Gig
gings.
was reluctant to trace cut another line for
this work, before any company was formed OF
ability and determination 10 push it throughi
but consented when Mr. Riddle informed me
he had already collected enongh from the citi-
zens 10 pay the expenses Of preliminary sur
vey.
began at point upon my old line l6 feet
above the terminus at Olney. and commenced
working up the creek, ascending l6 feet to the
mile.
After measuring the sinuosities for four miles,
perceived that this grade could not be adj
hered to without running up the creek an un-
reasonable distance. In addition, the line was
fast leaving the fiat table land on top of the Ca
fon and running into the divide upon very
steep ground. therefore dropped the level24
feet and continued on ascending ten feet per
mile.
This grade struck feet above ihe water. al
a point on Clear Greek two miles above Mr..
Vaudeventers house in Oak Boitom-makins
miles.
Arrived at the head, my notes Of survey
showed the following amount Of work TO be
done.
The first twelve miles of the line passes over
very favorable ground being easily excavated
and great portion of it nearly Hat. This brings
TO the Trinity trail, where the road would be
crossed by aque,luct 90 feet high. SO far
would be required us rods OF hume, at an av-
erage height of six feet.
Crossing the road, the line is throw on a rath-
er steep hillside, and after toriuous course of
24 miles, arrives upon the plateau In the rear oi
Mr.. Maher's house.
Nearly the whole of the excavation for the
remaining miles would be through soft,
shelly rock, over ground which would require
| on average % feet cut on the uppnr side, to
obtain a level surface whereon TO commence
| The ditch.
| Aside from the aquednct ht Whiskey creek,
| which would be 60 feet hish and 240 feet long,
| there would be required between the trail and
| the dam site, 270 rods of hume, at an average
| height Of ten feet.
| Twas disappointed in not being able TO obtain
as much fall as expected, which involves the
necessity of increasing the capacity OF the canal
| IN order to obtain sufficient water to pay inter
es, on the money invested. ! have therefore
based the calculations npou canal OF sufficient
! size 10 GARY sixty slulcc waters-l500 cubic
! feet rer minute, after deducting 20 per cent tor
| waste. ---
| This deduction is not made insiew of the loss
| by seepage, which would be trihinS after the
| ditch had become coated over by the sediment
| from the creek wafer but on account Of the re-
| tardation of the currept, caused by the unavod-
| able crookedaess OF the line.
| To carry this amount of water there, with the
fall of ten feet per mile the ditch must be of the
| following dimensions: 8 feet wide ON top
| feet on bottom, and feet deep.
In the first six miles from the dam down,
there would be le,500 cubic yards excavation,
worth 60 cents per yard. and amounting TO So
800. The balance of The dig6ing-44,oS0 cubic
yards, can be done for As cents per yard The
huming the first six miles, which requires
81 500 feet of lumber, Il have estimated to be
worth f7,70s which sum includes the cost of all
! 8 foot dam. The balance of The tiuming will
take so POO feet lumber. which, together with
! the bent timber and cost OF erection, have cal
| culated at Sc 05l.
| donot consider it necessary in this place to
| give every detail on ihls estimate on the humns
| / will lnt rely remark that have calculated the
| cost OF the W hskey creek aqneduct at 81 ,s0G
| aud the cost OF all the lumber has been placed
! at SIS per thousand, deiivered.
The sum OF these amounts being $43,5S5,
add 10 per cent for superintendent aud all con-
/ lingent expenses, which gives aggregate OF
S4I,/ 49S as Tie entire cost OF Introducing sixty
sluice waters on 10 the digsings at Oney &c. Ii
IS presumed, OF course, that This amount of wa
ter would be doubled by receiving the dis
charge of the canal during the night into reser-
voirs-several of which could be constructed al
very little cost at the head OF .Isckass fat and
Oregon Gulch, by daming the mouths OF some
| small flat Clutches there.
Although this line will cost nearly half as
much that run off by the Shasta county mi
ming and water company. and yet ufforos only
about one-third The amount of w.fer still ii has
| the advantage over the old line in one iDpor-
tau, particular-while nearly all the work 10 be
done upon the latter is huming, by this line it is
mostly excavation. which avoids the necessity

| did not consider il necessary 10 stake off this

undertake the work in future TO do so with
open eyes. so that. when once begun. there will
be some prospect OF the completion OF this long
talked of undertaking--to accomplish which
there has already been made many spas
modic efforts.
