The Biological Station of the University 

 of Michigan 



A station for instruction and research in biology will be main- 

 tained by the University of Michigan, for the tenth season, as a 

 part of its regular Summer Session, during the eight weeks from 

 July i to August 23, inclusive, 1918. 



LOCATION 



The Station is located near the Engineering Camp of the Uni- 

 versity on a tract of about 3060 acres of land owned by the Univer- 

 sity and stretching from Douglas Lake to Burt Lake in Cheboygan 

 County, Michigan, 17 miles south of the Straits of Mackinac. This 

 region, diversified by hills and valleys, was formerly covered by 

 forests of hardwoods and conifers. Small tracts of the former still 

 remain. It contains many lakes of clear water, unsurpassed in the 

 state for size, depth, and beauty of setting. The elevation of the 

 camp, between one and two hundred feet above Lake Michigan, 

 insures cool nights. 



Six miles to the west of the camp on the Grand Rapids and In- 

 diana Railway is the nearest railroad station, Pellston, a town of 

 some 1,300 inhabitants, with a bank and a variety of retail establish- 

 ments. Topinabee, on the Michigan Central Railway, is 8 miles from 

 the camp. Fifteen miles to the northeast, also on the Michigan Cen- 

 tral Railway, is Cheboygan. A state road connects these points and 

 passes near the laboratory. Except for two small summer resorts 

 on Douglas Lake the region for miles about is almost uninhabited. 

 Douglas Lake is two and one-half miles wide and nearly four miles 

 long. Its shores are everywhere wooded, in some places low and 

 receding, in others rising in terraced bluffs 70 feet in height. The 

 beach is of clean sand and the lake bottom slopes gradually into deep 

 water. 



OPPORTUNITIES FOR BIOLOGICAL WORK 



The physiography of the region in which the Biological Station 

 is located, the types of vegetation present, and the kinds of botanical 

 work which may be carried on at the Station have been described 

 by Dr. F. C. Gates, in his report to Director Glaser in 1916, as 

 follows :
