Now, for this last sum, we could have built a sufficient railroad across the Isthmus of Panama, and another across the continent, from the Mississippi to the Pacific. If such a road, with its suitable equipment, cost $100,000 a mile, and the distance should amount to 2,000 miles, then the $200,000,000 would just pay the bills. That would have been the greatest national work of productive industry in the world. In comparison with it, the Lake Moeris and the Pyramids of Egypt, and the Wall of China seem but the works of a child. It might be a work to be proud of till the world ends; one, too, which would advance the industry, the welfare, and general civilization of mankind to a great degree, diminishing, by half, the distance round the globe; saving millions of property and many lives each year; besides furnishing, it is thought, a handsome income from the original outlay. But, perhaps, that would not be the best use which might be made of the money; perhaps it would not have been wise to undertake that work. I do not pretend to judge of such matters, only to show what might be done with that sum of money, if we were disposed to construct works of such a character. At any rate, two Pacific railroads would be better than one Mexican war. We are seldom aware of the cost of war. If a single regiment of dragoons cost only $700,000 a year, which is a good deal less than the actual cost, that is considerably more than the cost of twelve colleges like Harvard University, with its schools for theology, law, and medicine; its scientific school, observatory, and all. We are, taken as a whole, a very ignorant people; and while we waste our school-money and school-time, must continue so.
