From Bac, under the protection of the presidio of Tubac, some thirty miles farther south, later transferred (1776) to the present Tucson, Garces carried on his work. He made five great entradas from the time of his arrival in June, 1768. The first was in that same year, the second in 1770, but in these he did not reach the Colorado, and we will pass them by. In the third, 1771, he went down the Gila to the Colorado and descended the latter stream along its banks perhaps to the mouth. On the fourth, 1774, he went with Captain Anza to the Colorado and farther on to the mission of San Gabriel in California, near Los Angeles, and in his fifth, and most important one, 1775-76, he again accompanied Captain Anza, who was bound for the present site of San Francisco, there to establish a mission. Padre Font was Anza’s chaplain, and with Garces’s aid later made a map of the country.* At Yuma Garces left the Anza party, went down to the mouth of the Colorado, and then up along the river to Mohave, and after another trip out to San Gabriel, he started on the most important part of all his journeys, from Mohave to the Moki Towns, the objective point of all entradas eastward from the Colorado. The importance attached at that time to the towns of the Moki probably seems absurd to the reader, but it must not be forgotten that the Moki were cultivators of the soil and always held a store of food-stuffs in reserve. They were also builders of very comfortable houses, as I can testify from personal experience. Thus they assumed a prominence, amidst the desolation of the early centuries, of which the railway in the nineteenth speedily robbed them.
