Thomas said lie stated object Of digging tho
ditch was to drhtn Mud Lake; but it Beolnod
guoer to him that channel should DO cut from
tho river into the awamp aud ALLOW tho wator to
1ow into tho lnud, to orain It.
Tue Chairman remarked that nIr. Wentworth
expected vossels to mil on tho ditch boforo long,
aud to have elevators scattorcd along it's banks.
Mr., Thomas also stated TINT the moro wator

plying tho canal, great difference was porcopti-
ble In tho rtyor, From bis observations, he bo-
lcved the rlyor would DO ceanncd once IN forty
oiyht hours now, II tho ditch wero hIlcd up, Or

The Mayor asked II the ditch was the only

did not bceye any sediment except that in Boln

that the bod of tho rivor wnB fcet lower than

called the attention Of tho Canal Comsnissioners
to tho digging Of the ditch, and be took look at
It. Tho Doard doBred them to take some action
to prosent tho excavation, nlnco It would provo
to to Chicago rna defeat tho an for
minds that it was impossible for them to inter
fore. as the dotritus would not be carried into
the canal. They, however, beosmo alarmed
tho canal would be washed away, and tic City OF

tho wator from the oanal, especially should the

port, and ordered a. guard.tam ts bo

100000 cubic foot Of water minute would
flow into tho canal In case OF IN overflow OF tito
Desp]ainos. He beloved it unquostionable tha',
it the canal received all tho water, ~ designed
from the Chicago River. ut tho ordinary stage Of
tho lake, 1t would remove every cubic foot Of
wator ii the river once in forty-yovon hours
provided nothing stopped tho,how. 1n caso Of
An overflow HOW, they could protect the canal
from damage, but not the southwestern portion
Of the city. Ho nlso confirmed whne the other
Commissioners Baid about tho flow Of water
through the ditch preventing just 10 much
water passing from tho rirer into the canal.
THE REMEDIES.
Tho Mayor Desired to know II thero waa no
rl1
10 filed up. Col. Utley thought thoro were two.
One waB to put dam at tho upper end OF tho
ditch aud lot the water rim iii its natural channol
ind the other WAS to onurgo the canal to 100
feet in wiatl, aud feet in depth. Tho latter
would give currout in the river OF 65-100 Of d
mile In an hour.
Commissioner rrindiylllc said tho Bonrd Ind
done everything possible to remedy the evil, but
tho great difficulty experienced was to get
private individual to como forward anu tako

cute it, provided tie city would pay all tho legal

cano necessary.
COMMISSIONER Pn1Nb1y1LLE
continued: Engueor Uhosbrough Ind an idea
promise might be mado with AIr. Wentworth
and the others Interested to stop the flow Of
wator, or to control it by lock, tho oity authors
tics to decide when my bono!lt was likely to ariBo
by opening tho cato aud lettiny tho water run
into the Wost Fork. During tho wot aeasou 1t
might bo advantageous; hut during tho dry goa-
son. by closing tho lock, the water from the river
would pass into tho caual. Ho believed such an
arrangement oould be nude with tho property
OWnotB
hlr. Dralnara inquired ii tho aoalmont would
not come along with tho water whom tho lock
Was openod.
Commissioner Prfndville rcp1iod that tho city
would control the lock, aud il it woro found
best to keep it closed all tho time it could be
dono. The Donrd had built dam in tho ditch
by teroo. OF ia higA-Aandcd proeeed!ng," al It
WAS called by tho newspapers, but 1t was cut
through, and tho flow OF water had boen siuco
uninterrupted.
