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 eighth season, as a 

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

 July 3 to August 25, inclusive, 1916. 



LOCATION. 



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

 versity on a tract of about 2,200 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 unin- 

 habited. 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. 



The topography immediately about the Station is such as to 

 afford a variety of floral and faunal conditions. The region is char- 

 acteristically sandy and the home of ground pines, wintergreen, and 



* During the past two seasons the total rainfall has been between 

 three and four inches each year. The average temperature for July has 

 been 69 and for August 66°. The average daily maximum does not 

 exceed 8o°, and the minimum frequently drops to 45 during the night. 

 The general proportion of pleasant days is so high that field work is seldom 

 interrupted.
