the Miocene fauna of Kansas and eastern Colo- 
rado, of which much remains to be done; Mr. 
Gidley is working upon the Pleistocene horses, 
and has just completed a very careful revision 
of the species; Dr. McGregor is working upon 
Belodon and the Phytosauria, comparing the 
American and German types; Professor Osborn 
is especially studying the Titanotheres. At 
Princeton, Professor Scott is working up the 
Patagonian mammals. In the Carnegie Mu- 
seum, Mr. Hatcher has just completed a me- 
moir upon Diplodocus. 
EVOLUTION OF THE HORSE. 
A FRIEND of the American Museum of Natural 
History has recently presented a fund, which 
is to be used exclusively for the collection, ex- 
hibition and study of the fossil horses of America. 
Professor Osborn has planned two expeditions 
for the coming season, with the especial ob- 
ject of filling gaps in the already rich series. It 
is proposed also to mount as complete a series 
of fossil skeletons as possible, showing all the 
chief stages in the evolution of the horse from 
Hyracotherium to Equus. Four complete skele- 
tons have already been procured, two of which 
have been mounted. It is also proposed to ex- 
hibit recent types of skeletons, showing the 
effects of artificial selection. H. F. O. 
AN ARCHEOLOGICAL MAP. 
BENEDICT’S map of Chain-O’-Lakes, near 
Waupaca, Wis., copyrighted by F. M. Benedict 
in 1896, although not well known, is yet of 
considerable value and interest to archeologists. 
It locates the Wisconsin and Wolf River Indian 
trail, and by numbers indicates village sites, a 
bake hole, kitchen middens, graves, and coni- 
eal, ovals and effigy. mounds. 
The location and description of such remains, 
however brief, are always valuable. The great 
number of archeological sites, and the com- 
parative ease with which they could now be 
located and described, seem to cause local 
students to ignore the great need of present 
work in this line. They donot realize that the 
facilities for the work at the present time are 
far better than they will be a few years hence, 
when but a fragment of the same results could 
be accomplished. Mounds plowed over are

harder to find, and crops ruined by the excava- 
tions of the explorer are more expensive than 
anything injured on wild Jand. Permission of 
owners is also harder to secure in more thickly 
settled regions. In this connection Mr. Ben- 
edict’s efforts certainly are commendable. 
It is very desirable that such a map be con- 
structed by every local student or lover of 
archeology, until every county in the country 
is covered. It might be saved for future use 
either by being published or by filing duplicate 
copies of it in several libraries or museums. 
Certainly specimens found by such students 
deserve a careful record and preservation in 
the nearest substantial public museum or col- 
lege.

THE BIOLOGICAL STATION OF THE UNI- 
VERSITY OF MONTANA. 
THE Biological Station of the University of 
Montana will be open for its third season begin- 
ning July 22d, for four weeks. The laboratory 
is near the P. O. of Holt, Montana, at the 
northern end of Flathead Lake, and from it a 
great variety of collecting grounds is easily 
accessible: Flathead Lake is 32 miles long and 
16 wide, with an elevation of 4,000 feet ; Swan 
River debouches into the Lake near the station, 
and numerous other large and small streams, 
swamps, smaller lakes, forests and mountains 
with an altitude of ten thousand feet offer a 
variety of conditions not within ene of many 
similar institutions. 
Courses in zoology, botany, omnitholony and 
nature study will be offered. A small party 
will leave Missoula early in June and will make 
explorations in the Cabinet or Mission moun- 
tains, reaching the Laboratory at the beginning 
of the sessions. 
The facilities of the station which are placed 
at the service of students and investigators em- 
brace a gasoline launch, row-boats, botanical 
apparatus, insect nets, pumping apparatus, etc., 
and a team and wagon equipped with camping 
outfit. 
The New York Botanical Garden will co- 
operate in the botanical work of the Station. 
Dr. D. T. MacDougal, director of the labo- 
ratories in that institution will join the party in
