On the fifteenth, after saying mass, we continued our route to the west by a dry and stony ravine which there is between the mountains, and at 3 leagues we met some Indians taking water from a small well in earthen jars, who, on seeing us, ran away, flying from fear; but at two musket shots we overtook them, treated them kindly, and brought them back to the well that they might assist in watering the horses, giving them all the water necessary, for the reason that they had not drunk the day before. For this reason we called this place Paraje de las Ollas. They were naked people, and only covered their private parts with small pieces of hare skin; and one of them was so aged that by his looks he must have been about 120 years old. We continued to the west over barren plains, arid and without pasture, a country as sandy as a sea-beach, until we reached the sand-banks, where the horses had great difficulty; and after another 7 leagues Father Kappus and the other people camped without water, and with only pasture of salt grass; but Padre Kino and I [Mange], with guides, and the governor of Los Dolores [Aguerra], in order to be forehanded, went west 2 leagues farther, crossing the bed of Rio San Ignacio; we arrived at the banks of an arm of the sea to which, in the sixty years that the province of Sonora had been peopled, no one had come, and we were the first who had the great privilege of seeing the Island of the Seris and that of Tres Marias, as well as the mountains of Cuatro Evangelistas, in California, on the other side of the gulf, the width of which, according to the measuring instruments at this position of 30° [actually about 30° 35'], is some 20 leagues. We returned to the bed of the river [San Ignacio], where we found a well nearly dry; we drew from it water for the horses, who had had nothing to drink, and took some ourselves, although it was turbid, muddy, and disagreeable.
