A petition for immediate annexation was presented to the Government of the United States by a large and representative body of Mexican citizens, which pleaded for an extra session of Congress to convene, which occurred with results satisfactory to each nation. And Mexico became a part of the United States of America without further delay. More than one hundred years had passed since the memorable event, and Mexico had grown to be possibly the most important part of the United States. There had been a long reign of peace and prosperity, and the fact that this part of the United States had been, long ago, a hot-bed for internal revolution, was only known to the present generation by reading from the pages of history an account of her brave people struggling for independence—struggling for enlightenment; for the maintenance of a republican form of government. The two great scientists and their most able coworker were of purely Mexican origin; in no existence previous to this one had there ever been any mixing of blood. Governor Lehumada took no especial pride in the fact that there was no Anglo-Saxon or other than his native Latin blood in his veins. Neither did the other two great scientists—Guillermo Gonzales or Julio Murillo. They had no prejudices; they were too intelligent and learned. They advocated intermarriage of the races. They believed that it was necessary for a high degree of intelligence to be preserved. However, their own existence—the very high degree of their intellectuality and spiritual development was an exception to the rule they advocated. There are people who without apparent cause carry prejudices in families for hundreds of years, and while their real feeling may not have any publicity, is only due to the fact that no occasion presented itself for them to declare their opinions. There are a few of this class of people living in the capital of Chihuahua, who pride themselves on the fact that they have never crossed the Rio Grande; that they do not speak the English language; that they have no associates amongst the Anglo-Saxon American people. These persons are not without influence, often being people of wealth and position; and they now believed their time had come to make known their views concerning the race question. Many of the large newspapers were full of the absurd ideas of these people. They claimed that the wonderful discoveries of their two townsmen were due to the fact that through their veins coursed no foreign blood. They claimed they could see through the shadows events which foretold the complete extinction of the Anglo-Saxon race on American soil and the re-establishment of the Mexican Republic. Sensational papers published their articles, and wise people laughed at them over their morning meal.
