NATURAL SCIENCE NEWS. 



Pinon Jays, 



Cyanoccphalus cyanocephalus, arrived 

 here early last fall and have remained 

 with us all winter. 



Large flocks could be seen passing 

 over the city in early morn on their 

 way to the fields where they fed on 

 wheat and alfalfa seed. 



They probably inhabit the high mount- 

 ain regions of Colorado but I have 

 never observed them on the plains be- 

 fore. Will Burnett,

Natural History. 



For Natural Science News. 



All the wonderous things of Nature — 

 Objects of the earth and sea — 



Are engaged in ceaseless effort, 

 Writing out their history. 



Monstrous planet, tiny pebble, 

 Grain of sand, whate'er it be — 



Is a faithful, grave historian, 

 Writing tomes of history. 



Rolling stones when dashing downward 

 O'er the mountain fast and free, 



Leave their marks upon the granite — 

 Imprints of their history. 



Dried-up brooklet, ancient river, 



In their journeys to the sea, 

 Left behind them well worn channels — 



Records of their history. 



Oft we see a freak of Nature, 



Which we call a mystery, 

 But a close investigation 



Will unfold its history.
