Two passages luive been surveyed and levelled, to open a commu- 
iiication between Crabti-ce Crcelc and the Little Yotighiogeiiy: the 
one from Crabby's Ann, and the other from Wilson's Foric to the 
latter stream. They woidd each rcfjiure a, tunnel, .Snjjposing its- 
bed on a level with the base mark, the t«5uiel from Grahisy's Arm 
"woidd extend three miles l,5S8 yards,, and the tifiniel froniAViison^s 
Fork four miles 300 yards, in length, vvith a)i ope)i cut at each of 
their extremities^ to the depth or" thirty-five feet. The greatest 
height of the ridge, above the bed of the tnnnci from Crabby's Arm^ 
would be 444 feet, and above that of Wilson's Fork £53 feet. The 
distance from tlieir eastern exti-emities to Swaji's Mill would be tv>, o 
miles, with a fall of 114 feet.. From Swan's Mill, to the mouth of 
Crabtree; Creek, the descent would ba 94f) feet, on a distance of 
seven miles 966 yartls; from the mouth of Crabtrce Creek, to that 
<jf Savage River, in the Potomac^, the distance iivc miles 830 yards,, 
and the descent 378 feet. Thus, from the eastern exi remit}' of tiie 
tunnel, to the mouth of Savage lliver, tiie total descent is 1,432 feet, 
an a distance of fifteen miles eighty-six yards, and of these two tun- 
wcls, the one by Crabby's Arm is the shortest. 
Other passages have alsi) been examined, to open communications 
between Deep Creek and t'ic waters of the Little Y(n:g!',iogeny. The. 
bed of the tunnels required for this purpose, was fixed seventeen feet' 
above the level of the base mark. One of these tunnels joined West- 
tick Run, to one of the bi-aiiches of the south ft.rk of Deep Creek; 
its length was two miles 583^ yards, and it required a deep cuU on. 
the side of W\'st-lick Run, of the length of one nn'le 600 yards, and 
another on the side of Soutli Fork, of the length of two miles 50* 
yards. Anotber tunnel migiit join the Little Youghiogeny itself, to 
South Fork; it would extend one mile 1,300 yards in lengtli. and 
requii-e an open cut of one mile 1,566^ yards, towards the Little 
Yougiiiogany, and two ndles ?00 yards tov, ards tiie South Fork. 
Tiie height df the ridge, ab(»ve the fn\st tunnel, ^vould be 143 feet, 
and above the second, 183 feet. Such are the chief passages through 
Avhich a communication miglit be opened between the waters which 
descend fj-om the eastern a5id wostinm sides of tlie Little Ijackhono. 
In recapitulating tlifc' several routes, by which the canal >ny be di- 
rected through them,, we will observe.- that they all extend; fi'om tin? 
Tnouth of Savage Rive-', either hy the valley of that stream, or Crab- 
tree Creek, to the base mark on the bridge of Deep Creek;, and that 
the descent or fall of the canal, by all these routes, is i:,4S'-2 feet. 
1st. The first asceiids by Savage Riv«r, Monroe Run, Meadow- 
Mountain Run^ and Deep Creek. Its total lengths from the nmutli^ 
of Savage River to tlie !)ase mark, is t^venty-one miles 325 yards. 
The length of the tunnel, which it re({nires througk the ridge, is 
iivc miles 833^ yards, and the height of the ridge above its bed, 21 S. 
feet.
