Another record of 39.27 ft. on a curve, gave for the cost of the brick work at sides the same result as above, but the inspector's record of men working on concrete backing at sides showed a less cost, as follows:
| 4 men mixing at $1.75 | $7.00 |
| ⅔ time man lowering at $2.25 | 1.50 |
| 1 man in bottom | 1.75 |
| —— | |
| $10.25 |
They placed 12.7 cu. yd. at a cost of $0.81 per cu. yd. This figure probably more nearly represents the average cost than the $1.06 reported in the first instance.
The cost of placing the anchor bars on straight sewer, representing average progress, at another time, was found to be:
| 1 man | $3.50 |
| 1 man | 1.75 |
| —— | |
| $5.25 |
They placed the steel for 44 ft. of sewer or 1,650 lb. at a cost of 0.32 of a cent per lb.
Further notes for 6 days' work, when it seemed to represent as nearly as possible the general average for the whole were:
Labor on arch concrete:
