Of notable interest is the fact that certain members of the Jones expedition were so deeply interested in what they saw that they made request for immediate return. So, October 18, 1876, there started southward, from Salt Lake, at the direction of the Church Presidency, another expedition, in character missionary, rather than for exploration. It embraced Helaman Pratt, Jas. Z. Stewart, Isaac J. Stewart, Louis Garff and George Terry. Meliton G. Trejo joined at Richfield. Phoenix was reached December 23, there being found several families of the Church who had come the previous year. The day the missionaries arrived happened to be exactly thirty years after the date on which the Mormon Battalion passed the Pima villages on the Gila River, just south of Phoenix. The members of the party worked all over southern Arizona, especially among the Mexicans and Indians. In February of 1877 headquarters were at Tubac. In April, after a Mexican trip, a letter was received from President Brigham Young asking that Sonora be explored as a country for possible settlement. Later in May the Stewarts started eastward, in continuing danger from hostile Apaches after they had crossed the San Pedro. On the road, while the missionaries were passing, a mail rider was killed. At Camp Bowie the Apaches were found beleaguering the post. East of that point the Stewarts had to replace a wagon tire just as they were passing a point of Apache ambush. Return to Utah was in December, 1877. It was concluded that border settlements better had wait on Indian pacification. Trejo was a remarkable character. He was of aristocratic Castilian birth and had been an officer in the Spanish army in the Philippines. It would appear that he became interested in the Mormon doctrine, which, in some manner, had reached that far around the earth, and that he resigned his commission and straightway went to Utah. There his knowledge of Spanish, backed by good general schooling, made him valuable as a translator, though his English was learned in the Jones family. His later work was in Arizona and Mexico, as a missionary, his home in 1878 moved to Saint David on the San Pedro, where he died a few years ago. He was a fluent writer and sent many interesting letters to the Deseret News. In January, 1878, he wrote from Hayden's Ferry:
