BIOLOGICAL RECONNOISSAXCB AT FLATHEAD LAKE- »5 



After reaching the station and depositing a large proportion of the 

 Inggagf; a trip was taken to the foot of the Swan Range eastward. Host 

 lake and Echo lake were partially studied. Several excursions were made 

 into the range, with packs on backs, and many peaks ascended. 



In Angttst, Dr. H. C, Cowles, from the University of Chicago, with » 

 party of nineteen stndents, spent ten days at the laboratory. The entire 

 party, with many others, made the ascent of the Swan range In safety, 

 returning la/len with specimens. More detailed Information relative to 

 these mountains and their lakes Is given lat^er. 



Dnrlng the summers of 1900 and l&Ol, 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 neating birds near the laboratory were mado 

 a special study, and a good series of nests and eggs secured, notwitli- 

 standing the weather was very bad most of the time. The results ot 

 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 tlie entomoHtraca of the lakes and rivers in the 

 western part of the state, ho far as the travels during the summer per- 

 mitted. His observation}; 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 

 be 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, Host lake, Silloway 

 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 botanlsU from the Unlrersity ot 

 Chicago, carried on studies in forestry. Large collections of plaits were 

 made, forestry conditions carefully considered, and a large series of phO' 

 tographic negatives made. Prin. P. M. Silloway spent the month of Juna 

 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.
