Of this list the foreman of the brickyard is a temporary appointment. The foreman of carpenters at the West End has finished his work and retired. The foreman of masons was discharged by the commissioners, and has entered into the employ of Mr. Farren at the West End.

There are nine foremen of the heading gangs, two of whom have $100 per month, and the remainder $3.00 per day.

The heading gangs consist of eleven drillers each, including the foreman, and from three to five rockmen for removing stone. They work by shifts of eight hours, relieving each other at 8 A. M., 4 P. M., and 12, midnight. The blasts are made about the time of relief. The men working on the enlargement under private contractors make two shifts a day, each shift working ten hours. The Committee made a special examination of the number of men employed under the engineer and superintendent, with a view of considering whether the force actually engaged was necessary to an economical prosecution of the enterprise, intending to suggest any reform that might occur to them as essential; but learning that the engineer would in the course of the year make some reduction in the number of the men as well as of the teams employed upon the work, the Committee deferred taking up the subject until the anticipated reductions should have been made. And now understanding that the commissioners have the whole matter under consideration, and that they have already to some extent, acted thereon, the Committee for reasons that would be obvious, withhold any recommendations or remarks upon this point.

System of Operations.

The general superintendence of the labor on the work is vested in Mr. Hill. The reports are made to the engineer. The captains in the tunnel report weekly the proceedings of each day under the following heads, as follows:—

Number of days' work.
of holes drilled.
of inches of holes drilled.
of drills dulled.
of pounds of powder used.
of feet of fuse used.
of sheets of paper used.
of pounds of soap used.
of pounds of candles used.
of quarts of oil used.
of lamps used.
of pounds of wicking used.

The captain at the shafts four times a month reports,—

The days' work of the engine-men.
The revolutions of the engine.
Number of pounds of coal used.
of feet of wood used.
of gallons of sperm oil used.
of gallons of kerosene oil used.
of pounds of tallow used.
of pounds of waste used.
of pounds of tar used.
of cages raised.
of cars of stone raised.
Size of pump-plunger used.
Length of stroke.
Number of strokes.
of gallons of water raised.
of boilers in use.

The materials furnished for the construction of the work are charged in their distribution to twenty-three accounts, as will be seen by the tabular statement of its cost. Requisitions for materials are signed by the immediate overseer, captain or foreman; they are handed to the superintendent for approval, and by him forwarded to the engineer. If the requisition is approved by both, the materials are ordered, and when furnished the applicant signs upon a duplicate his receipt for the same. This course is pursued as well for materials taken from the State lands as for those purchased. Suitable blanks for returns, requisitions, &c., are furnished to the several points, and the evidence of all the transactions is preserved in the office of the engineer. In addition to the above, a return of all material broken, or laid aside, is made to the engineer, at whose office a substantial account of all materials on hand, either in use, or out of use, may be found.

The organization of the working force, and the mode adopted for supplies and expenditures at the various points, appear well adapted to an efficient and economical prosecution of the enterprise.
