Cost Data.—­The pipe from Bonito to the railway was laid by contract.  The price was 18 cents per lin. ft. laid and back-filled from the railway to the Nogal Reservoir, and 28 cents from Nogal to Bonito.  In addition, 50 cents per ton per mile was paid for hauling pipe, and extra compensation for setting valves.  From Coyote, east along the railway, the work was done by the railway company under the writer’s direction.

The total cost of laying 384,300 ft. of wood pipe, from 11 to 3-1/2 in. in diameter, was $18,156.77, or 4.72 cents per ft., divided as follows: 

Ditching $0.0249
Laying 0.0113
Back-filling 0.0110
               -------
    Total $0.0472

This includes unloading from the cars.  Train service cost 1/3 cent per ft. additional.

The pipe gang, including back-filling, consisted of 1 foreman, at $100 per month, one assistant foreman at $75, and about 30 Mexicans at $1 per day.  The rates were the same in the ditching gang.  The plow team cost $6 per day.

Including all general expense, the cost does not exceed 6 cents per lin. ft.

The cost of laying 101,300 ft. of 12-in. cast-iron pipe was $23826.67, or 23.5 cents per ft., divided as follows: 

Ditching $0.0249
Laying 0.1180
Back-filling 0.0110
Lead 0.0790
Oakum 0.0014
               -------
    Total $0.2343

This includes train service and unloading pipe, but nothing for tools.  The foreman and inspector received $100 per month, the caulkers, $3; pourer, $3; melter, $2.50; 2 pipe-men, $2, and laborers, $1 per day.  Professional caulkers wanted $5 per day.  Carpenters, blacksmiths, and boiler-makers made good caulkers; their work is standing perfectly under a 275-lb. service.

The cost of the pumping plants complete per horse-power is as follows: 

Pumps $79.00
Boilers 18.70
Building 41.70
           ------
  Total $139.40 per h.p.

The approximate cost per million gallons of storage capacity is as follows: 

Nogal Storage Reservoir $103.00
Carrizozo Service " 3,040.00
Coyote " " 2,880.00
Luna " " 3,480.00
Corona " " 2,720.00

To cover general expense, 3% should be added to all the costs above given.  The costs per foot of pipe-laying include the setting of all specials, valves, and stand-pipes.  The difference of cost in laying 11-in. and 3-1/2-in. wood pipe is not nearly as great as the difference in diameter or the total quantity laid on record days.  While the record is 4,000 ft. and 8,345 ft., the 76 miles of pipe of all diameters were laid in a total time, including all delays, of 223 days, or an average of only 1723 ft. per day.  The cost of the 11-in. pipe is covered by 7 cents per ft.  The pipe was laid by a single gang as fast as it was received from the factory.
