The town of Santa Fe is provided with a Roman Catholic church, which, under the judicious management of the present bishop and clergy, is doing what it can to improve the condition of the Mexican population. Other religious denominations have not yet been fully developed; although the attempt is being made to establish churches of the Protestant faith on a sure and permanent footing; but this, although we regard it as certain, will take time, for the majority of the people lean strongly to the Roman Catholic faith. It is a very singular fact that among a population of seventy thousand souls included in the limits of the Territory of New Mexico, there have been such feeble and vain attempts made by Protestant missionaries to bring the people to their mode of thinking. The task might have been impossible when the country was under the jurisdiction of old Mexico; but, since it has changed masters, this excuse does not hold good. The Mexicans, as a body, learn readily; they easily discern between right and wrong; and, as the field for Christian enterprise to work in is large enough for all sects, it is strange that the Protestant church is not found laboring in the good cause, side by side with its Roman Catholic friend. It is true, there are a few persons struggling on under the auspices of the Protestant church; but they are so few that they are seldom met in the great expanse of the country. Santa Fe has long been celebrated as having a depraved population; but, as honest and honorable men are now working with satisfactory success for a reformation, the day cannot be far distant when this town will redeem itself. It is true that, not many years back, Santa Fe was filled with gamblers and desperadoes of all grades; but, at the present time, law and order is beginning to predominate, and it is to be hoped that the next generation will see a better state of affairs. The vices which have characterized the inhabitants have not been confined, by any means, to the Mexicans; but rather they have been exemplified in those Americans with bad characters, who have, from time to time, crept in among the people. These men, in several instances, have set examples which the most debased Mexican would hesitate to follow.
