the Fortietieth Parallel Survey is probably the equivalent of the 
glacial period of the East. It is so regarded by Clarence King, 
in his “ Report,” and was certainly subsequent to the time when 
the early men flourished.—W. Y. Independent. 
The preceding abstract suggests the following observations. 
Some of the vertebrata reported as found with the human remains 
in the auriferous gravels are obviously out of place, or erroneously 
determined. Thus, Elotherium does not belong to the Pliocene 
fauna, nor even to the Upper Miocene (Loup Fork) but to the 
lowest Miocene or Oligocene (White river). Mastodon obscurus 
is Upper Miocene. How they come to be included in'the list re- 
mains to be explained. : 
The occurrence of human implements mingled with the Plio- 
cene fauna in Oregon, was asserted in this journal for 1878, p. 125, 
and some dozen species of vertebrata cited as cotemporaries. 
more extended list of the mammalia was given in the Bulletin U. 
S. Geol. Surv. Terrs., 1879, p. 48; and of the birds in the same. 
for 1878, p. 389. The entire number of vertebrata now determined 
from this locality in Oregon amounts to twenty-seven, 
During the past summer the writer obtained bones of Mylo- 
don from the auriferous gravels of the Klamath river,near Yreka, 
Cal., from excavations which he personally examined. He also 
obtained vessels of vesicular basalt which were undoubtedly pro- 
cured from the same excavations. 
The relation of this formation to the European Pliocene is dis- 
cussed in an essay on the parallelism of the American and Euro-

GEOGRAPHY AND TRAVELS.! 
HAYDEN’s New Maps oF Wtomne, ETC.—The forthcoming 
reports of Dr. Hayden's Geological Survey, on the field-work of 
1877 and 1878, will contain three topographical atlas sheets, of 
the same size, and on the same scale (4 miles to an inch) as those _ 
in the Colorado atlas. These sheets illustrate portions of Wyo- 
ming, Idaho and. Utah, each of them covers 214 degrees of longi- 
tude, and 14% degrees of latitude, and includes an area of about © a 
11,000 square miles. 
The south-eastern of the sheets covers the country from longi- _ 
tude 107° to 109° 30’, and from latitude 41° 45’to 43°. Itincludes 
the barren plateaus of the continental divide, north of the Union 
Pacific R. R. The valleys of the Sweetwater and Wind rivers, — 
and a part of the Wind River range. 
The south-western sheet lies directly west of the latter, extend- 3 
ing to longitude 112°. It embraces the Green River basin, and, | 
farther westward, a succession of parallel ranges of no ‘great —
