OCT-DOOR EQUIPMENT. 



era] acres extent, have been set apart by the trustees for the 

 purposes of a biological garden. Both plots are wooded and 

 traversed by deep ravines. Plot a being at the front of the 

 campus is to be used chiefly for ornamental planting of native- 

 shrubs and trees. Plot b is more secluded, and is more freely 

 used for the ends of biological instruction. It contains the 

 pond, and the winter house shown in the third figure of the 

 plate. Its ravines exhibit, especially on the shady side, a luxu- 

 riant tangle of shrubbery and vines, of flowers and ferns, so 

 little disturbed by civilizing influences that the native Cypripe- 

 t/imii regime and Adiautum pedatum — usually the first victims 

 of their loving friends — still flourish there abundantly. The 

 first thing done in this plot was taking measures to preserve 

 the native species still present, and to restore to it a number 

 that had been already exterminated. The next thing, was the 

 assembling of those biological and ecological types especially 

 useful for illustration in general course work. Plants are raised 

 here not for themselves alone but for the sustenance they afford 

 to the forms of animal life desired to be retained with them. 



where nature had done much, and where the material needed 

 was all near at hand, attention has been given to making things 

 as readily available for study in the field as they are in the lab- 

 oratory, to the end that field studies that are really worth while 



Hut two things that are obviously artificial have as yet been 

 introduced into the garden: a plankton apparatus and a winter 

 house. Probably no college teacher has witnessed a good plank- 



accounted too complicated and too expensive for the equipment
