ITINERARY 



Mr. Charles H. Richardson, Jr., and the writer left Berkeley 

 on May 10, 1909, arriving at Winnemucca, Nevada, on the fol- 

 lowing morning. From there we journeyed by stage to Quinn 

 River Crossing (Mason's Crossing), seventy-five miles to the 

 northwest. One night en route was spent at Amos (Cane 

 Springs Station), and one at Tregaskis Well. The morning of 

 May 14 found us at our first collecting ground. 



Camp was established one mile from the buildings of the 

 Quinn River Ranch on "Wheeler Creek, tributary to the river 

 (see map, plate 7). Practically three weeks (May 15 to June 8) 

 were spent at this locality. Twelve miles in a northwesterly 

 direction from Quinn River Crossing is found Big Creek Ranch, 

 the second collecting station. This ranch is located at the base 

 of the Pine Forest Mountains. It constituted the first camp of 

 the "biological cross-section" series (see map, plate 7). By 

 establishing collecting localities from one side of the mountains 

 to the other, 1000 feet apart as regards altitude, we hoped to 

 obtain precise data on the range of species, life zones, and com- 

 parative distribution of forms on the two sides of the mountains. 

 Big Creek Ranch was the base camp for all further operations, 

 which had to be conducted by means of pack animals. We 

 remained in this locality two weeks (June 8 to 23). 



The next camp was at the head of Big Creek (8000 feet), 

 where the time from June 23 to July 6 was spent. This became 

 the secondary, or mountain base of supplies. The following 

 camps were then established as parts of the cross-section plan : 

 Big Creek (6000 feet), July 6 to 8; Big Creek (7000 feet), July 

 8 to 10; Duffer Peak Meadow (8400 feet), July 10 to 12; Alder 

 Creek (7000 feet), July 12 to 14; Alder Creek Ranch (5000 

 feet), July 16 to 18; Head of Big Creek (8000 feet), July 19 

 to 29. The gaps in the series were thus filled, and the east-west
