THE very flattering reception which the sumptuous holiday edition of “The Heart of the White Mountains” received on its début has decided the Messrs. Harper to re-issue it in a more convenient and less expensive form, with the addition of a Tourist’s Appendix, and an Index farther adapting it for the use of actual travellers. While all the original features remain intact, these additions serve to render the references in the text intelligible to the uninstructed reader, and at the same time help to make a practical working manual. One or two new maps contribute to the same end.
