Another Pioneer Book, and though oversimplified, an excellent introductory book to the subject of the Lewis and Clark expedition. The factual data is based on primary source material, a procedure that educators today heartily endorse. Tousey has done the best job of the three (the others are Kit Carson and Davy Crockett) but Clark is a less glamorous figure so needs a bit more pushing for the market. One criticism is sure to be made,- the playing down of Lewis in order to center Clark. Paste-down on cloth binding; reenforced.
