And on the other hand are the Mexicans who govern the land, making it their chief business to bait and loudly curse these same foreigners. The name of the foreign oil men is anathema in Mexico to-day, and the busiest game of any Mexican official is the oratorical denouncing of the sponsors of the industry. But, we cannot forget, these Mexicans have not and do not turn a finger to the replacing of great foreign activity by any constructive form of Mexican enterprise. At basis the difficulties of the oil companies and the Mexican governments are psychological--and an understanding of those psychological bases is the rarest flower in the intellectual nosegay of most of those who discuss either Mexico or oil. First of all is the companies’ belligerent insistence on the principles of vested rights as the first and only basis for the oil discussion--naturally distasteful to those whose single idea is to upset those rights. Another psychological element is that the foreigners’ very respect for law and the continuity of government and their insistence that Mexico live up to their own ideals is in the first place quite beyond the conception of the Mexicans in power to-day and in the second place such an attitude is inevitably maddening to the weaker brother whom it seeks to benefit. Because the foreigners believe in Mexico, the Mexicans will not believe in the foreigners. Another disturbing factor is the very success of the oil companies and of the foreigners whom they employ. I have told, above, something of the picture of the Tampico that was and of the Tampico that is. It has changed in yet other ways, and most of all in the makeup of her population. In 1908 there were perhaps two score Americans and English in the town, and the chief industry of the place was--tarpon fishing! To-day there are 8,000 Americans and a thousand British and Dutch, and the swaggering, free-money, noisy, busy atmosphere of the frontier, of the oil fields, of the white man on his bully-ragging, destructive, inconsequential “education” of the dark brother round the world, permeates the place. Its influence is not academic, but somehow one feels that Tampico is a monument to the genius and faith of the Americans who made it great. The restless power is there, the restless making over of the world that it may be a better place for the white youth of the future to stamp about in, for the dark brothers to build their new homes in.
