All the various obstacles raised by climate would have been minimized if construction had proceeded more slowly. Indeed, Mr. Hood and Mr. Strobridge, engineers in charge of construction, agreed that if the Central Pacific had been built at less speed, and as such railways are usually constructed, the expense would have been from 70 to 75 per cent less than the actual cost. The saving would not have been due altogether to the abandonment of winter construction, but this would have been an important factor. The Central Pacific, however, preferred speed to economy, in the hope of outstripping the Union Pacific in the race for the business of Nevada, and for the subsidies and land grants offered by Congress. _Supplies._ A further obstacle in the way of successful construction of the Central Pacific lay in the difficulty of getting supplies. Wood and stone could be procured in the mountains, but iron, coal, and manufactured articles of all sorts, including rails, locomotives, and cars, were brought from Sacramento or from the East. Prices in general were high, in part because of the war. The first ten locomotives purchased by the Central Pacific Railway cost upwards of $191,000; the second ten upwards of $215,000. Iron rails cost $91.70 per ton at the mills. The price of powder increased from $2.25 to $6 during the period of construction. The cost of food was exorbitant. Hay was worth $100 a ton out upon the line, and oats about 14 or 15 cents a pound. Stanford says he sold one potato for $2.50.[101] In the cases cited, high cost of transportation often played an important part in determining the final prices, and in general, indeed, the expense of moving supplies was comparable with the initial cost. Among many possible illustrations one may mention the fact that shipments of rails via the Isthmus of Panama as late as 1868 cost, for transportation alone, $51.97 per ton, making the total cost of the rail delivered at Sacramento, $143.67, not including charges for transfer from ships at San Francisco, nor for transportation up the Sacramento River. Nor was this freight rate high when compared with the cost of wagon hauls in the mountains, when material had to be transported away from the finished track. Mr. Huntington tells of meeting some teams with ties in the Wahsatch Mountains. He continues: They had seven ties on that wagon. I asked where they were hauled from, and they said from a certain canon. They said it took three days to get a load up to the top of the Wahsatch Mountains and to get back to their work. I asked them what they had a day for their teams, and they said $10. This would make the cost of each tie more than $6. I passed back that way in the night in January, and I saw a large fire burning near the Wahsatch summit, and I stopped to look at it. They had, I think, some twenty to twenty-five ties burning. They said it was so fearfully cold they could not stand it without having a fire to warm themselves.
