miles in an air line. This place is described in the notes as being 
at the head of a canon, in a sort of basin, elevated about seven 
thousand feet above the sea, and encircled by mountains which 
rise from two to three thousand feet higher. 
From some further remarks on the general character of the 
range, I quote the following: “The Chiricahua Mountains are 
situated in the southeast corner of Arizona, some of the foot-hills 
even reaching the line of New Mexico and the Mexican state of 
Sonora. Several >small streams run east and west from their 
summits, those of the former division emptying into the San 
Simon Valley ; of the latter into the Sulphur Spring and San Ber- 
nardino Valleys. The first two water-sheds are comprised in 
the Rio Gila system, while the San Bernardino Valley stretches 
southward, and water from it flows into the Pacific near Guaymas.” 
“These valleys are usually grassy plains, but there are scatter- 
ing bushes, mostly mesquite, in some of them. The scrub oaks 
begin with the foot-hills ; they are evergreen, the leaves being 
insensibly replaced with new ones in May. A little higher the 
juniper (called c cedar ’ by the people here) comes in. Still 
higher, on the north side of the hills, there is a little pihon and 
scrub pine, while the summits are heavily timbered with red and 
black pines. In the gulches some fir grows, and on the hillsides, 
mostly near the summits and facing the north, occasional patches 
of aspen.” 
At Morse’s Mill three weeks were very profitably spent, and 
on April i a start was made for Tucson, the next objective point. 
The route led through Sulphur Spring Valley, Tombstone, and 
Cienega Station, and at all these places, as well as at some inter- 
mediate points, a longer or shorter stay was made for the purpose 
of collecting. These delays consumed so much time that Tucson 
was not reached until April 18. 
The country lying about this town and the neighboring station, 
Camp Lowell, proved so rich in desirable birds that it engaged 
Mr. Stephens’ attention for nearly the whole of the two succeed- 
ing months, during which, however, a brief visit was paid to the 
Santa Rita Mountains, where some important observations were 
made. 
The season practically ended with June, for the wagon-journey, 
begun on the 29th of that month, across the arid plains and 
scorching deserts of middle and western Arizona, was attended
