reached on the first of July. Collections and valuable notes were made by 

 the way, especially at the Carson River, seven miles above Fort Churchill 

 (June 23d), Fort Chiu-cliill (June 24th), Nevada Station (June 25th), Soda 

 Lake, on the Carson Desert, (June 27th), Sand Springs, (June 29th), 

 Fairview Valley, (June 29th), and Edward's Creek (June 30th). At Austin 

 we remained only a few days, when, departing for Ruby Valley, we arrived 

 there July 13th, and camped at the base of the mountains, some four miles 

 northward of Fort Ruby. Toward the last of August we left this place 

 and proceeded northward along the foot of the East Humboldt Mountains, 

 pitching camps of a few days' duration at intervals of the journey. Crossing 

 the range through the pass known as Secret Valley, near Fort Halleck, we 

 a})proached the iTpper portion of the Humboldt River, and in continuing 

 northward camped on several of the streams flowing from the lofty Clover 

 Mountains into the Humboldt. The month of September was principally 

 spent in traveling northward to the Humboldt "Wells," thence through 

 Thousand Spring Valley to the Goose Creek ]\Iountains, crossing which 

 we entered the southern portion of Idaho at the "City of Rocks," the 

 most northern locality reached; from whence our course directed eastward 

 toward Salt Lake City, where we arrived early in October. At intervals 

 dui-ing the pursuance of the route traced, small collections were made, when 

 opportunity pennitted; the principal stations being — "Overland Ranche," 

 Ruby Valley, (August 26-29), "Camp 22," Ruby Valley, (September 4-5), 

 Secret Valley (September 6-8), Bearing's Ranche, Upper Humboldt Valley 

 (September 10-12), Trout Creek, Upper Humboldt Valley, (September 16- 

 20), Thousand Spring Valley (September 21-24), "City of Rocks," southern 

 Idaho (October 3), and Deep Creek, northwestern Utah (October 5). 



1869.— On the 20tli of May of this year, collecting was begun at Salt 

 Lake City, and continued until June 21st, when we proceeded to Parley's 

 Park, about twenty-five miles to the eastward, in the Wahsatch Mountains. 

 In the meantime, Antelope, Stansbury, and Carrington Islands, in the Great 

 Salt Lake, were visited. On the 2d of July an excursion was made, in 

 company with the botanists of the expedition, eastward to the western 

 spurs of the Uintah Mountains; there we remained from the 3d until the 8th 

 instant, when we returned to the main camp in Parley's Park via the Provo
