BIOLOGICAL RECONNOISSANCE AT FLATHEAD LAKE. 95 
After reaching the station and depositing a large proportion of the 
luggage a trip was taken to the foot of the Swan Range eastward. Rost 
lake and Echo lake were partially studied. Several excursions were made 
into the range, with packs on backs, and many peaks ascended. 
In August, Dr. H. C. Cowles, from the University of Chicago, with a 
party of nineteen students, spent ten days at the laboratory. The entire 
party, with many others, made the ascent of the Swan range in safety, 
returning laden with specimens. More detailed information relative to 
these mountains and their lakes is given later. 
During the summers of 1900 and 1901, Prin. P. M. Silloway, of the 
Fergus County High School, spent the months of June, July, and August 
in the study of the birds. The nesting birds near the laboratory were mada 
a special study, and a good series of nests and eggs secured, notwith- 
standing the weather was very bad most of the time. The results of 
the work are embodied in the bulletin from the Station (21). He also 
made extensive studies of the birds in the Mission range and 
in the Mission valley on the west of the range. During this time a 
large series of skins was secured, now deposited in the museum of the 
University, and a large amount of data collected relative to the birds of 
the state. This gave excellent opportunity for studying those birds 
which make the state their summer residence. , As a matter of fact there 
were less than a half dozen birds noted which apparently came from the 
north on their autumnal migration. 
L. A. Youtz, of Columbia, devoted two months of the summer of 1900 
exclusively to the study of the entomostraca of the lakes and rivers in the 
western part of the state, so far as the travels during the summer per- 
mitted. His observations extend to the waters of Sinyaleamin lake, 
McDonald lake, the ponds and creeks in the Mission valley, Flathead 
lake from one end to the other, Flathead river, Swan river, Daphnia and 
Estey’s ponds, and to this was added the material from Swan lake after 
he left the. party. 
During the following summer the work was continued by the writer, 
assisted by Maurice Ricker, of the Burlington, Iowa, High School. The 
same lakes and rivers were visited, as also Echo lake, Rost lake, Siloway 
lake, Placid lake, Trail lake, and other smaller bodies and streams of 
water. 
In 1902 work at the Station was continued during July and August. 
Mr. Harry N. Whitford, with a party of botanists from the University of 
Chicago, carried on studies in forestry. Large collections of plants were 
made, forestry conditions carefully considered, and a large series of pho- 
tographic negatives made. Prin. P. M. Silloway spent the month of June 
at Swan lake, and July at the Station. He secured much information ad- 
ditional to that given in his bulletin “Summer Birds of Flathead Lake,” 
which will be incorporated in a supplementary report. The work of col- 
lecting entomostraca from the lake was continued by Mr. Maurice Ricker, 
of Burlington, Iowa, and the writer.
