visible. At the time of our visit these had been 
removed, and used for building the barracks.. There 
were two hundred soldiers, artillery and infantry, 
here, under the command of Major Heintzelman. The 
officers and men were living in tents, covered with 
sheds made of branches to protect them from the sun. 
The post was established the year previous, but, not

fresh provisions and vegetables had engendered the 
scurvy among the soldiers. 
The fort had heretofore been supplied by land 
from San Diego, at an enormous expense; but a par-

the place by water. A vessel loaded with stores was 
sent up the Gulf of California, and succeeded in getting 
some distance up the river; but owing to the strong 
current she could not reach the fort. Wagons and 
scows were therefore sent down to bring up the pro- 
visions, a labor attended with nearly as much risk 
and expense as bringing them all the way by land 
from the coast. It was in contemplation to procure a 
small steamer for fetching the supplies from the head

advantage in exploring the Colorado above the fort. 
In connection with the survey of the river Gila, it
