be safe in saying, that the system is more extensively 
and methodically practised than elsewhere. The Yu- 
mas, and other tribes on the Colorado irrigate their 
lands, and raise wheat, corn, melons, etc. The Mogquis 
and the Navajos, far to the north, do the same; and 
the warlike Apaches, who are more nomadic in their 
habits than any tribe west of the Rocky Mountains, 
raise corn when driven to extremities. But the Pimos 
and Coco-Maricopas have made agriculture more of a 
system. Their lands are better Srvigealocl their crops 
are larger, and the flour which they make from their — 
Wheat and maize is quite as good as the Mexicans 
make, except in their grist-mills. 
Tam inclined to think that Major Emory in his 
Report has greatly over-estimated the number of these 
people. “He states, that ‘the population of the Pimos 
and Coco-Maricopas together is estimated variously at 
from three to ten thousand, and that ‘ the first is evi- 
dently too low.”* From information obtained from the 
chiefs, and the Mexican officers in Sonora, I should 
not place them above two thousand. Captain John- 
‘Ston,+ another officer attached to the army under 
- General Kearney’s command, in estimating them as 
embracing ‘“ over two thousand souls,” came very near 
the mark. Of the number stated by me, I was ae 
that two thirds were Pimos. 
Their complexion is a dark brown, differing oes 
that of the red-skins east of the Rocky Mountains, and 
from the olive cast of the California tribes. The 
women have good figures, with full chests and finely
