In some, if not in all, instances this channeling is sub-let by the contractor at the rate of 15 cents per square foot, making the cost about five cents per cubic yard excavated.The broken rock, as mentioned, is sent to waste along­side the canal by derricks, the principal dimensions of which are shown in the illustrations. It is understood that wasting the rock is sublet to the Brown Hoisting,/7, ^r2 ^ .7^^ C -^ -)^  JtZ^  C^i y *—>T  ^ £^ -^t_S^  y^'rUii G y-A  j y - ^/ yGZl:U '/AG7A C ^ ' .-^ c T ^ L ^ ^X — <•X / ' .% " / ^i ?  ^  i3 ~, cy^"^/ ^ '  ^ z , j^  ' / < :/  Zj .t<L-^/d, /  X"Z -< --e^ ^  ^  - t _ ^  ^2-t3 ^-tJi(/f^ 'C^Q s,^ ^  - '''*^  i -^t-'T—< _ ( ^  ~^^ _^_Ci^ y/r 7 ./ 2 i d ,d k l  ^ ^ ^ 4 -ni2 j ^C37,  ^< 1-^  ^ / ?  ^32^''3 ^ 2  0'^ y~"2.^ i—y_,^  2 ''^ -'< -^: 2^<27-1^ / l-a .^ 2 < 3  ^/^  'T ^  . j^ i /—z)/ zJ J -J—<--t—•*s,.'t^ (iw  cZ-«z—-i-'T_ '^'-t.V"'?^^3  ^  ^ O t^ , y  cp^ ^ y^Ze^Z ^  pZZ. ,c /Z  .AT irZ ^  c^w ^„iL^ZZ^   ^ ZZZiy ~Z u^^r'Z -a^Z ^Z Z c7x^fzZ'A^L-c—^y^<l-y^^.^ ~'.^ -£y(^  oyy')T-Z.>^ %^_'Z'lr-'^ C^^-'i-Z C-^i^<5i^-z.-'<i-t----y, a^Zut-C^ ^  ^  CZc^. yi>Z<3 ./ 6-■  ^(yir~z$L^ <2^^;^en ^  c -jty^  is' ______ .^  % :i .y2 , /. aX ^ ^ » -~ > - t > ^ (^ . ^■'X .x_j)i.y( < s^-'Ziv /<yo 'i^'^ '-y/ y^^ -^iy-'s^yiy' AC^. ^  7 ^  c ^  ^  „c - ^ y y  ^ < 2 ^ y y(x ^ y  y y ^ , y ^ r ^ i' M ( T ^ y y y '  / y A .A7Z ^  Zz,------- --------------------------a—«—X----<2 "tV ,.9 '~ ^ -y^  \z-'d Z z Z i '? / ' /C L -a-..--r.^  ^ < - ^ - 4 2 . , ^ ^c //s ^ ~~M^2 l > .-'2A-'’%yTy^'^^ 2J2^ L^  4 -^-e -A ^ /y  yy^a ^  O -T '-z ^ y f ,yy^  y  ( y y ^  y f  ~ y jx .y z y - tL ^ — g-^^g— > ^ - 1 ^ ^ .
