The Cascade Grotto is too wildly beautiful to pass unnoticed. De- 
scending over twelve hundred feet in an hour, we plunged into an In- 
dian garden, where were melons, maize, and beans, and to our surprise 
a field of cotton. This fertile spot is an inclined plain, evidently formed 
by deposit from a mineral spring, which gushes from the mountain, 
irrigates the fields, and then follows a ravine, leaping from cliff to cliff, 
in beautiful cascades, until it joins the Gila, which appears in view a 
thousand feet below the garden. Passing beneath the first water-fall, 
one enters a charming stalactite cave, consisting of two apartments, 
richly decorated. At the foot of the precipice are flowering shrubs and 
matted vines, whose red flowers gaily contrast with the surrounding ver-

This smgular formation is filled with petrifactions. In one place 
was seen the trunk of a large cotton-wood tree completely petrified, and 
cropping out from a bed of coarse lime-stone. A chip showed distinctly 
bark and fibre. 
From this point the Gila was inaccessible; and having hired an In- 
dian from the hills, we followed his guidance, and reluctantly turned our 
backs to the river. Surrounded by a great body of Pinal Llefios, we 
passed through their strongholds, and on the Ist of November again 
struck the Gila, probably not more than ten miles below the point at 
which we left it. 
Having surveyed up as far as possible from this place, we then fol- 
lowed the course of the Gila to the mouth of the Rio San Pedro. Here, 
while observing moon culminations for longitude, we sent a party eighty 
miles to the Pimo village, where flour was purchased. December 9th, 
I met this party on its return. When we arrived at the Pimo village, 
Colonel Craig, with our escort of twenty-three men, and Captain Barry, 
with about twenty-five days’ rations, were awaiting us. The banks of the
