says Font, “are the same as the Opas.” By following 
the course of the river, which it appears the Fathers 
did, the thirty-two leagues they travelled from the 
Pimos, would bring them to the western end of the 
jornada, where they found the Coco-Maricopas. 
It has been asserted that ‘‘the Maricopas have 
removed gradually from the Gulf of California to their 
present location in juxta-position with the Pimos.”* 
I cannot learn that they ever were on the Gulf; 
although it appears from the missionary authorities, 
that there was a band of them on the western bank of 
the Colorado, ‘“ living in a valley thirty-six leagues in 
length, and, for the space of nine leagues, remarkably 
fertile and pleasant,” who were “allied to the Coco- 
Maricopas of the Gila.” But from the early accounts 
of the Indian tribes on the Gila, it appears they occu- 
pied the valley from a point west of the jornada, where 
Father Font found them in 1775, to the Salinas above 
its mouth. Father Sedelmayer met them in 1744, 
about the same place on the Gila, living on peaceful . 
terms with the Pimos, and used them for his guides to 
the Colorado. It appears that at this time, too, they 
were living on the Salinas, in the very district that we 
passed over in our visit to the ruins on that river.

of two rivers, the Salado and Verde.”. These, on their
