From ttie comparison of these tlirpo routes, it is eviflomt that the 
Hecoud is pretciahle to the first. I'heir Icrii^th is iKarly the same, 
hut the fir. t rrtjiiircs six miles of tutnielliiig and two tunnels, whilst 
the second re(iuirc« only one tunnel of somethini^- less than four 
miles in length. The thiid is shoitet* again by four miles than the 
second, and j)asses by the same luimcl. A?jued(!Cts must be con- 
structed on this route to cross Hoy's Run, Steep Run, Sang Run^ 
Gap Run, and Bear Creek; but by the successive dropping of its 
Jevels, they will require hut a small Gfevation,' and the waters of 
these runs, and of tiie Great Yougiiiogeny, may be raised, and use<l 
to feed the canal, an advantage which the other routes do not offer» 
It should also be observed, that thes<5 Runs are not above 200 or 
SOO feet wide at thei!* mouths, in the Youghiogeny. The third route 
ss therefore prelei-able to the two others, on the hyjjothesis of uniting 
the mouths of Sarage River and I5ear Creek, through the valleys of 
the Little and Gicat Yougiiiogeny. 
We will now coinpare this rwitc, which we w-}:' call theYoughio«- 
ejeny route, with those which lead from Crabtvee Creek to Dce[? 
Creek. 
Nine routes, which all unite at the base m^ark, have, as v e have stat- 
ed before, been examined for this purpose. Their length varies only 
from 19 to 22 miles, hut their tunnels p»Tsent a much greater differ-' 
ence. The long<\st extends 5 miles 833^ yards, or about 5 2 miles^ 
and the slmrtest 1 nsile 6S3| yaids, or about 1| mile in lengths 
The last should certainly be pr'efeired; its whole length is 21 mile* 
718 yai'ds; and tlie greatest height of the ridge, above its tunnel, is 
22.7 fret. We shall call it Dcwickman'^s Ai'tn rontc. 
We have also (jbserved, tliut there ai-e three routes from the Base 
mark to the mouth of Bear Creek. 'I'he first runs 12 miles by Buf- 
falo Marsh Rtvn, and Rock Lick Run. It is the shortest, but re- 
ijuires two miles of tunnelling. Were it not for this obstacle, it 
offers a favorable gtowid for digging the canal. The second, wind- 
ing round Panther's Point, and the heads of Hoy's Run, Steep Run, 
Sang Run, Gap Run, he. is 24 miles long, and is objectionable, not 
nnly from its length, but from tiscdilHculties \\hich it presents in turn- 
ing i'anther's Point. The third, by the Talleys of Deep Creek, and of 
the eastern branch of the Youghiogejiy is 20 miles long,* it is shorter 
hy four miles than the second, and rerpiires no tunnelling. In thi» 
sespect it is superior to the first,* for two miles of tunnel costs more 
than eight miles of cftnal, \\hich is the diffei-ence of their lengtli*. 
The passage of an active trade will also meet v.ith ewre delay on a 
tunnel of two miles, unless its dimensions are very laige, than oa 
four or six miles of Canal. This route possessing besides, over the 
two others, the advantage of feeding the canal below the mouth of 
Beep Creek, by raising the waters of the Great Youghiogeny and 
its tributaries, is preferable to them in all respects. 
If we add the 20 miles of this route to the 21 miles 718 yards of 
Dewjckman's Arm route, wc shall have for the whole length of the 
Ctvna!; passing along Crabtiee Creckj Deep Creek, and the valley
