"Doctor Hafen has prepared in The Overland Mail a very valuable book on one of the most picturesque phases of the American 'Westward Movement.' Many diaries and annuals, heretofore published, have mentioned the pony express, the stage coaches, and the early Ocean Mail to the Pacific Coast; but here we have the whole subject carefully studied and beautifully printed... The mail routes studied are from the Central West to the Pacific Coast. The latter term is made to include only the area from San Diego to Portland, Oregon."
