The several lines thus converging to a point excepting the two last, 
which are, however, brought to a parallel position and equidistant, 
nearly from their object, the mouth af Bear Creeky the continuation 
of them, in comparison^ may be thus pursued: 
The 10th and 11th have two alternatives. 1st. To cross Deep 
Creek over the falls by an aqueduct to Panther Point, then turn that 
point in high rocky excavation, and descend 150 feet to the river 
shore, near Hoy's Run, and continue down along the Ginsing Bottoms 
to the ravine of Winding Ridge, pass through it five miles, and iii 
about fifteen miles frooi the point, reach Bear Creek. Or, 2dly, as- 
cend along Deep Creek, cross it at the rapid by an aqueduct, pass 
through Panther Ridge by a tunnel of half a mile; then, either cross 
Hoy's Valley by an embankment and aqueduct, or turn it by a cii'cui- 
tous line, and gaining the west branch of Bear, descend to the mouth 
of the creek, about 24 miles. These distances added to the former, 
make by one route, 51^ miles. 
By the other, 60i miles. 
The Glade lines having converged to the centre at the bridge, the 
tompa»nson may next be made between that which has the shortest 
tnnnel and that which has the least distance; these are the 2d and 
the 9th. 
The second line has to tlie centre point the length of, miles 
15.0035 yards. If we continue the lineup Buffalo Valleij till the 
digging becomes 35 feet deep to a tunnel, not exceeding two miles, 
under a ridge of 170 feet, the distance is, miles 14.0000, which, ad- 
ded to the preceding, is miles 29.0035 yards. Or, if we take the 
length of the 9th line, with the shortest tunnel, it is 30 miles 732 
yards. 
This would evidently be the lesat expensive route, through at a 
higher level; and the question of supply of water comes next in order. 
Canals in England being in a very different climate, do not, in 
regard to water, afford data on which fully to rely. Our own expe- 
rience is not conclusive, since the Santee has required to be deepened, 
and Middlesex was not made originally with that precaution which 
might have allowed it to be a guide in this estimate, nor has Erie 
Canal been long enougii in operation to exhibit the minimum of its 
consumption of water by filti-ation. The canals of France, whose 
climate most resembles that of the middle states, differ greatly from
