heur lake and alkali flats. Princeton is a mail station east and south of 
Burns on the edge of Malheur flats, and at the base of a long lava mesa. 
Then the road turned southeast, going over and through the north end 
ve Stein’s mountain and down to Alberson’s ranch on the east side of the 
ange. Then down to the old Alvord ranch on the east side of the range 
which lies just east of the highest part of Stein’s Mt., on the edge of the 
desert. From here the road goes south to Field’s and Denio, the latter being 
on the line between Oregon and Nevada. 
From here to Winnemucca is a succession of flats and low volcanic 
mesas and sagebruch to Winnemucca. 
Throughout htis region the season was past for plants. In going around 
the divide leading over on to Carson desert, and going out of this area near 
Wadsworth, there was an interesting group of plants got along the way in 
the sand. This region is about 4500 feet alt. above 
Lake Tahoe is in the Middle Temperate life zone mostly. 
La Grande Oregon. There may be some misapprehension about the 
spelling of this name. It is not Spanish but French from those who first 
settled the region. There seem to have been many Frenchmen in the log- 
ing camps around this place in the early days. It is on the beautiful plateau 
that is inclosed by the Blue mountains on the southeast and the Wallowas on 
the east, and an extension of: the Blues on the west. It is a magnificent 
and nearly level valley all grassed over, and has a very fertile soil of black 
loam; and is well watered by streams coming down from the adjacent hills. 
ECOLOGICAL NOTES 
For nomenclature see Contributions No. 13. It may be well to say that 
Merriam’s Lower Sonoran is Tropical, his Pichi Sonoran is Lower Temper- 
ate, and his Transition is Middle Temper 
Practically all of my Texan trip was in eee Tropical, which I did not get 
out of except a little in Huachuca Mountains, a small area west of Silver 
City, New Mexico, at Cloudcroft; and the region around Artesia and west- 
ward, which probably was Lower Temperate. Near Sonora, Texas, the 
crests of the hills show an influx of Lower Temperate, but there is no good 
zonal plant to use as a guide in that region, for the Juniper i is surely J. occi- 
dentalis var. monosperma, and not Utahensis, and it is not subject to the 
zonal limitations of Utahensis. 
In the June-July trip I did not get up into the upper zone in the Provi- 
dence and Old Dad mountains. A little east of Hackberry , Arizona, the 
Rock. The lower seoes of the Kaibab are ered Lower ecaseaie and
