living nature is utilized at Lake Lorest College, where the work 

 is not that of a summer season spent far from home, but that of 

 daily college life, done about the doors of the college halls; not 

 the research work of graduates, but the general-culture work of 



The plan here has been to use things near at hand. In a 

 large measure, therefore, the situation accounts for the things 

 that have been done. The accompanying map (Fig. 1) of the 

 campus and its immediate environs shows some of the deter- 



the scarcely perceptible eastward slope of a terminal moraine, 

 which parallels the shore of Lake Michigan, and is covered with 

 fine oak woods. It is intersected by sharp ravines that have 

 been cut by puny postglacial streams. The ravine shown in the 

 map is scarcely more than a mile in length, and attains a depth 

 of about 70 ft. where it reaches the lake level at its mouth. On 

 the ridge at the head of these streams is a series of shallow 

 ponds, many of them temporary, and some of them doubtless 

 occupying old "buffalo wallows." I [alf a mile farther westward 

 the Skokie winds its leisurely course through the marshes at the 

 foot of the more abrupt westward slope of the moraine. The 

 Skokie and its marshes, the ponds, the upland woods, the 

 ravines, the crumbling outer face of the "bluff" and the Lake 

 Michigan beach, each furnishes its own peculiar fauna and flora, 

 and all are within easy walking distance of the campus. But 

 the woods, the ravines, and an artificial pond are upon the 

 campus, and are as easily entered for study as are the labora- 

 tories : and, naturally, these are most used. In the map c is

 feature of biological equipment — a veritable aquarium, perma- 

 nently stocked and self sustaining — teeming with a multitude of 

 forms of animal and plant life. Its proximity may be judged
