Wake-Robin (Hurd and Houghton), the name of a flower whose bloom marks the arrival of the birds, is the pleasant title of some very pleasant musings on nature in general, and birds in particular. Mr. BURROUGHS has the eye of a keen observer, and the sentiments of a genuine poet, and his pleasant talk about the birds makes a book of very pleasant reading. It is really worth more than that if one will take his cue from this book, and will study for himself the habits of the birds, whose interpreter Mr. Burroughs is content to be. So doing, he will find them capable of affording him a degree of both enjoyment and instruction of which those unstudious of nature know nothing.
