| Steel | $2.50 |
| Gravel and sand | .75 |
| Sand (bought) | .30 |
| Cement | 1.57 |

| Per cubic yard | $5.12 |
It is of interest to note the cost of the gravel and sand, as this includes the cost of digging it, wheeling it in a wheelbarrow an average distance of 100 ft., and then screening it and putting it in two stock piles. The proportion of bought sand used with the creek sand was one-half.
The old wooden floor and stringers had to be torn down. This was done at a cost of $1.30 per M. ft. B. M., and furnished 60 per cent. of the lumber needed for forms. The floor boards were 3-in. yellow pine planks, and the stringers 6×12-in. timbers, rather heavy, but money was saved by using them. The 6×12-in. timbers were used for props for the centering. Additional lumber was bought, delivered at the site of the bridge, for $20.84 per M. ft. B. M.
In framing and erecting the forms the carpenter had laborers helping him, he doing only carpenter's work, the laborers carrying and lifting all pieces wherever possible. The carpenter's work was about 40 per cent. of the total labor cost, which was as follows per cubic yard of concrete:
| Tearing down old bridge | $0.08 |
| Lumber | .85 |
| Nails | .15 |
| Labor, carpenter | .77 |
| Labor, laborers | .96 |
| —— | |
| $2.81 |
The forms were torn down by laborers, with the assistance of a man and his helper, who were given the boards for this labor and to haul them away. This reduced this item somewhat, as it only amounted to 20 cts. per cu. yd.
The cost of the forms per thousand feet board measure was:
| New lumber | $20.82 |
| Nails | 1.44 |
| Labor, carpenter | 7.60 |
| Labor, laborers | 9.50 |
| Tearing down | 2.00 |
| ——— | |
| $41.36 |
All the men, including the carpenter, worked 10 hours per day, and were paid at the following rates:
| Carpenter | $2.50 |
| Sub-foreman | 2.00 |
| Laborers | 1.50 |
