A regular foreman was not employed, but an intelligent and handy workman was given 50 cts. additional to lead the men and look after them when the contractor was not present.
A gang of six men did the work of mixing and placing, and as the stock piles were close by the mixing board no extra men were needed to handle materials. Water was secured from the stream in buckets for mixing. The mixture was made very wet. The cost per cubic yard for the entire structure was as follows:
| Preparing for mixing | $0.04 |
| Cleaning out forms | .06 |
| Handling steel | .03 |
| Mixing and placing | 1.15 |
| Ramming | .23 |
| —— | |
| $1.51 |
The cost of the contractor's expense of bidding, car fare, etc., is listed under general expense, and gives a total cost per cubic yard of:
| Materials | $ 5.12 |
| Erecting forms | 2.81 |
| Tearing down forms | .20 |
| Labor | 1.51 |
| General expense | 2.00 |

Example II.—For this bridge both the stone and sand had to be bought. The bridge floor was nearly 14 ft. above the bottom of the stream, which was shallow. The wages paid were as follows for a 10-hour day:
| Foreman | $3.00 |
| Laborers | 1.50 |
Carpenters were paid $3 for an 8-hour day and time and a half for all overtime, which they frequently made.
For the girders a 1-2-4 mixture was used. The cement, delivered at the bridge, cost $1.21 per barrel, there being 8 cts. a barrel storage and 8 cts. a barrel for hauling included in this. The sand was paid for at an agreed price per cartload delivered, which averaged $1.34 per cu. yd. The stone was crushed so as to pass a 1½-in. ring in all directions. It was delivered at the bridge for $2.75 per cu. yd. This makes the cost per cubic yard for materials as follows:
