On streams. A typically attractive entry from the series of 39 elementary science books produced by the Pennsylvania Writers' Project, all of which were published by Whitman. Most surviving copies are ex-library; to find copies that are not (as here) is not common. The artwork comes from the Federal Art Project, with the illustrator credited in the preface.
