SCIENCE FOR THE YOUNG.

BY JACOB ABBOTT,

Author of "The Young Christian Series," "Marco Paul Series," "Rainbow
and Lucky Series," "Little Learner Series," "Franconia Stories,"
Illustrated Histories, &c., &c.

Few men enjoy a wider or better earned popularity as a writer for the
young than Jacob Abbott. His series of histories, and stories

knowledge he imparts as in the story which he makes so pleasant a medium
of instruction. --_Buffalo Commercial Advertiser._
