ful, aspects of a bird is the instinct controlling 
its migrations, together with its power of com- 
munication with its fellows. What a marvellous 
ability these voyagers have, who, without a chart, 
and with only a very doubtful knowledge of sun, 
moon or stars to guide them, know how to find 
their. way unerringly through trackless space. 
It gives one a strange feeling, to wake in the 
dead of night and think of and occasionally 
hear the thousands of kinglets, red-polls, pine- 
creepers and black-throated greens, with others 
large and small, pursuing their weird flight 
over his head. By what language do they 
signal their gathering together for the long 
journey in spring? And when the movement 
is begun, is each a law unto himself, or do 
they elect a leader, and how is it done? Or, 
when they stop here and there for rest, what 
determines the resumption of the journey ? 
And at the close of summer, when their 
thoughts turn southward, how is the rendez- 
vous appointed from which the host is to re- 
turn to a warmer clime ? 
““ Who bids the stork, Columbus-like, explore 
Heavens not his own, and worlds unknown before ? 
Who calls the council, states the certain day? 
Who forms the phalanx, and who points the way?”
