The grade from the North Branch Canal is as follows: 1.757 mile to foot of plane No. 3-49 to 55 feet per mile ascent. 0.066 " level. 4.644 " summit level. 0.502 " descent toward Lehigh, T163696 ofa, foot per mile 9.448 " descent to White Haven, 47 to 60 feet per mile-Owing to the cheapness of coal at the inclined planes, it is estimated that the cost of transporting a ton over them will not exceed three cents each plane, 'which is made up as follows: --per home 120 $340 horses power, power per-80 hour, ls per day of 10 hours X 200 days, 2430 tons a year, at $1, --2430 3 engineers at 600, -------1399 9 hands, (2 at each plane and one-0 fireman, ) at $1 each for 250 ' days, --.'--------2%') Brought forward, $12,240 Iron bands, (for ropes, ) cost any $10,000, and last-four years, per year, --. 2,500 Interest on bands, --------600 Business, say 1500 tons per day, or _ ' 300,000 tons per annum, --1---$15,340 equal 5.1-10 cts. per ton for the 3 planes equal to----1.7 cts. for each plane.
