NORTHERN FLIGHT SOUTH OF THE FROST LINE, 109 
away. The bluewinged teals, like a coy maiden, re- 
main in the rice beds, associating with the Caro- 
lina rails and mudhens, all obeying instinctive and 
reasoning proclivities peculiar to themselves. But, 
sooner or later, they, too, tired and satiated with their 
southern relations, are impelled by Nature to turn 
their heads and again shape their course northward, 
where the lily pads are showing and the once ice- 
bound sloughs, lakes and swamps welcome them 
once more in their spring freshness.
