as Dam No. 7, which was then temporarily dispensed with, the estimate submitted ran as follows:
For the 50 miles above the mouth of the Cacapon, now better known as Dam No. 6 |
$4,440,657.00 |
For the 27½ miles between Dam No. 5, and that point |
1,640,000.00 |
| $6,080,657.00 |
Of this work there had been done, on the first of December, 1838: $947,394.27 on the 50 miles; and $1,589,453.44 on the 27½ miles. This left $3,543,809.29 as the work remaining to be done on December 1, 1838, to complete the canal to Cumberland. The work done in December was estimated at about $90,000 which reduced the amount remaining to be executed, on January 1, 1839, to about $3,450,000. The twenty-seven and a half miles between Dam No. 5 and Dam No. 6 were nearly completed at the time the estimate was submitted. In April, 1839, navigation opened to Dam No. 6, which remained the western terminus for a decade.
