"The series has this peculiarity, that all of its constituent volumes are independent of one another, and therefore each story is complete in itself.

OLIVER OPTIC is, perhaps, the favorite author of the boys and girls of this country, and he seems destined to enjoy an endless popularity.

He deserves his success, for he makes very interesting stories, and inculcates none but the best sentiments, and the 'Yacht Club' is no exception to this rule."-- _New Haven Journal and Courier_.
