326 HOMING WITH THE BIRDS

 ten days immediately following their arrival there 

 was snow a foot deep, unabated cold, and zero 

 weather, so that the birds became so sickened from 

 hunger that they starved and froze in large num-

 of food that kills them. There were very few 

 bluebirds and doves that season. The larks came 

 into the barnyards and asked the farmers for food. 

 A number of friends of mine fed larks with their 

 chickens, while for those two weeks I daily carried 

 coin, chop, and table scraps to the Valley of the

 once they had migrated they remained to starve 

 and freeze rather than to make the short return 

 trip, which would have saved them. It appeals 

 to me that one could not find clearer proof than 

 this that the birds do migrate at the dictates of a 

 subconscious command. When they receive this 

 command, they change locations, but nothing sug- 

 gests (o I hem that they could make a return trip

 are migratory birds. They are capable of flight, 

 which carries (hem in the neighbourhood of a
