late winter and early spring; and the Shore Lark (0. a. alpes- 
tris) that was noted in April. To the Shore Lark the breeding 
Prairie Horned Lark was indifferent, indicating that this latter

CONCLUSION. 
To one, who watched the Prairie Horned Lark on its home 
in the biting winds of January to the sultry sun of mid-July, 
no word fully expresses the deep impression made. To one, 
who has followed the vicissitudes of its life history through 
ever-changing seasons, interest in the bird becomes the more 
intriguing. Just a subspecies of a single species it is, but to 
one who would look deeply into its inner secrets, not even 
words in thousands express adequately the findings.
