Preface v Dr. Huth's kindness is also due the valuable bibliography for Chapters V-XI, for which the authors are greatly indebted to him. Hearty thanks are due to Mr. E. R. Smith of the Avery Library and to the publishers for their hearty cooperation in solving the complicated problems involved in the selection and reproduction of the illustrations. To Mrs. William T. Brewster we are indebted for the delightful water-color sketch of the plain of Argos from the citadel of ancient Tiryns (Plate II, p. 124). Besides photographs furnished by the University of Chicago Egyptian Expedition, many illustrations in Chapters I-XI have been contributed by a number of foreign scholars, to whom the authors would here express their thanks, especially to Bissing (Munich), Borchardt (Cairo), Dechelette (Roanne), Dorpfeld (Athens and Berlin), Hoernes (Vienna), Koldewey (Babylon), Montelius (Stockholm), Schaefer (Berlin), Steindorff (Leipzig), and some others, who have kindly furnished photographs and sketches. In these chapters (I~XI) the authors are also especially indebted to Messrs. Underwood & Underwood for permission to use their unrivaled series of Egyptian, oriental, and Mediter- ranean photographs as the basis for a number of sketches : Figs. 9, 10, 54, 57, 69, 72, 76, 80, 81, 83, 84, 85, 86, 87, 89, 90, 94, 103, 109, 117, also tailpiece, p. no. In no other way can impressions of the places and scenes where the men of the early world lived and wrought be obtained so vividly as by the use of these Underwood photographs in stereoscopic form. Teachers who make the Underwood stereographs, from which the above list of figures is taken, a part of their equipment will find that their teaching gains enormously in effectiveness. J. H. R. J. H.
