The authorities at Washington, however, did not rejoice as much. The real difficulty lay, not in landing merchandise at the ports, but in placing it before Mexican customers, and comparatively few of the latter could be reached. Persevering efforts were made to solve the problem on both coasts. Sometimes, for reasons not fully understood, the Mexican government issued licenses for the passage of goods to the interior, and for a consideration local authorities in the northeast did the same; but even these documents were not always valid against officials and military men whose "patriotism" had not been "sweetened." European merchants could see this difficulty. Up to October 20, 1847, only one small cargo from that direction entered the harbor of Vera Cruz, and Walker admitted privately that a very small part of the few imports was disposed of for consumption beyond the coast. In a word, this vaunted plan gave no substantial help on the problem of supporting the war.[33.18] [GOOD FORTUNE HELPS US] But by this time the good luck which has been supposed to keep an eye on the United States of America had intervened. In 1846 came the great Irish famine. British provision laws were suspended. Faced with starvation people cared little what they paid, if they could obtain food. Our agricultural products, which had fallen heavily in market value since October 1, 1845, rose with astonishing buoyancy. Western grain that had scarcely been worth transporting--frequently not worth it--became precious. A ship could earn thirty per cent of her cost in one round trip, yet hardly enough vessels could be found. So abrupt was the turn that a financial editor who had predicted on December 17, 1846, a speedy return to the distress of 1837, declared on January 30, 1847, "We are on the high road to an unprecedented prosperity." The abolition of the British corn laws ensured our farmers not only temporary relief but a permanent market. Cotton, too, and even cotton goods were in active demand abroad; and a famine in Germany gave us additional support.[33.19]
