bright eyes of the
bird whose body equals yours in physical perfection, and whose tiny
brain can generate a sympathy, a love for its mate, which in sincerity
and unselfishness suffers little when compared with human affection."

THE FIVE WORLDS OF LARIE

_Larus argentatus_, the Herring Gull.

Larie's "policeman," like Ardea's "soldier," is usually called a
"warden." No thoughtful or informed person can look upon "bird study"
as merely a pleasant pastime for children and a harmless fad for the
outdoor man and woman. It is a matter that touches, not only the
aesthetic, but the economic welfare of the country: a matter that has
concern for legislators and presidents as well as for naturalists. In
this connection it is helpful to read some such discussion as is given
in the first four references.

PETER PIPER

"A leisurely little flight to Brazil."

Peter, the gypsy, and Bob, the vagabond, are both famous travelers, and
might have passed each other on the way, coming and going, in Venezuela
and in Brazil. Peter, like Bob, is a night migrant, stopping in the
daytime for rest and food.

For references to literature on bird-migration, the list under the notes
to "Bob, the Vagabond," may be used.

GAVIA OF IMMER LAKE

_Gavia immer_, the Loon.
