NATURE'S CALENDAR 



ulous with curious and beautiful forms 

 of animal and vegetable life, now at the 

 height of their energy and attractiveness. 



" The animals of rocky shores," we are 

 instructed by that veteran in this study, 

 Prof. A. E. Verrill, of Yale, " are to be 

 sought for in a variety of ways. A few 

 occur quite exposed, clinging to the rocks 

 or weeds, in defiance of the surf. These 

 are chiefly univalve shells, barnacles, and 

 such animals as grow like plants, firmly 

 attached to solid objects — among these 

 are the bryozoa, hydroids, and sponges. 

 A much larger number seek shelter under 

 the rocks, or on their lower sides, or in 

 crevices and cavities between them ; these 

 must be sought by turning over the rocks 

 and exploring the cavities concealed by 

 the Fucus, etc. Many other species con- 

 ceal themselves still more effectually by 

 burrowing in the mud, gravel, and sand, 

 beneath and between the rocks, but must 

 also be sought for by digging with a spade, 

 stout trowel, or some other tool, in the 

 dirt exposed when the rocks are removed. 

 The number of curious species of anne- 

 lids, holothurians, bivalve shells, actiniae, 

 etc., which can be unearthed in this way 

 is always very surprising to the inexpe- 

 rienced in this kind of collecting. 



" Still other kinds can be found by care- 

 fully examining the pools and discovering 

 the smaller animals by their motions, or 

 by the shadows that they cast when the 

 sun shines, or by noticing their burrows,
