In the spring of 1869 the railroad was finished and a spectacular celebration was held near Ogden, in Utah Territory. The finishing stroke was everywhere regarded as national, since not only had Congress given aid, but the union of the oceans was an object of national ambition. With the completion, the problem shifted from the exciting risks of construction and finance to the prosaic duties of paying the bills, and with the shift came a natural falling-off in enthusiasm. The Union Pacific was the longest railroad of the sixties, and aroused the greatest interest. In an economic way it is merely typical of the speculative expansion of the North that began early in the Civil War and continued increasingly thereafter. The United States was engaged in a period of hopeful growth such as has followed every panic. After a few years of depression, stagnation, and enforced economy, business had revived about 1861. Confidence had increased, loans had been made more freely, and capital had taken up again its search for profitable investment. In the newer regions, where permanent improvements were least numerous, the field for exploitation had been great. The climax of exploitation was reached throughout the West. As had been true at all the stages of the westward movement, the West was heavily in debt, and upon a forced balance would generally have shown an excess of liabilities over assets. Borrowed money paid much of the cost of emigration. During the first year the pioneer often raised no crops and lived upon his savings or his borrowings. He and his local merchant and his bank and his new railroad had borrowed all they could, while the creditor, living necessarily in the older communities where saving had created a surplus for investment, lived in the East, or even in Europe. The necessary conditions of settlement and development had prepared the way for a new sectional alignment of business interests, those of the Far West and the Northwest taking their tone from the interests of a debtor class, while those of the East represented those of the creditor. The possible cleavage was revealed as real when the United States Treasury Department, in its work toward financial reconstruction, approached the subject of the greenbacks.
