Stronghand by Gustave Aimard

Mexico, considering its size, is one of the least populated countries in the world. With but few exceptions, the old Spanish colonies, since they have proclaimed their independence and become free republics, having been constantly engaged in war with each other, or in overthrowing the government they themselves elected, have seen all the ties attaching families to the soil broken in turn. Foreigners, no longer finding the necessary safety for their speculations in countries incessantly troubled by revolutions, have gone away. Trade has been annihilated; commerce has fallen into a state of atrophy; and the population has frightfully decreased, with such rapidity, that sensible men, who sought a remedy for this incurable evil, called emigration to the help of these states, which nothing can galvanise, and which only possess a factitious existence.

Unfortunately, the Hispano-American race is essentially haughty and jealous. Poor fellows, who let themselves be seduced by the brilliant promises made them, and who consented to cross the sea to settle in this country, found, on their arrival, and especially in Mexico, an ill-disguised hatred and contempt, which was displayed in all classes of society by ill will and aversion. Hence, being disgusted by their reception, and recognising the slight trust they could place in the promises of the men who had summoned them, they hastened to leave a country in which they had only found unjust prejudices and deplorable ill faith, and went to ask of the United States the protection refused them by those who had so pressingly summoned them.
