THE TRAVELS OF BIRDS 



Perhaps these children may themselves emigrate 

 to the forests of Oregon. Then what a zigzag 

 journey they would make to New York if like 

 birds they should be guided only by "inherited 

 habit"! 



Here comes in the difference between reason 

 and instinct. Instinct would send our children 

 from Oregon to Arizona, from Arizona to Da- 

 kota, from Dakota to Missouri, and finally 

 through Pittsburgh to New York City. 



Reason directs them to buy a ticket over the 

 most direct railway line between Oregon and 

 New York City, and they thus make their jour- 

 ney in the shortest possible time. 



Let us see how many, many miles the Cliff 

 Swallows of Nova Scotia might save if they were 

 to buy a ticket over what we may call the short, 

 Reason Route, instead of the long, Instinct Way. 



THE CLIFF SWALLOW'S ROUTE 



The Cliff Swallow winters in South America 

 and in summer is found over most of the United 

 States, except Florida, and north to the Arctic
