The public began to learn better what Charnay’s full and hearty confidence in his own sweeping assertions was, when he again entered the field in a series of papers on the ruins of Central America which he contributed (1879-81) to the _North American Review_ (vols. cxxxi.-cxxxiii.), and which for the most part reached the public newly dressed in some of the papers contributed by L. P. Gratacap to the American Antiquarian,[1001] and in a paper by F. A. Ober on “The Ancient Cities of America,” in the _Amer. Geog. Soc. Bulletin_, Mar., 1888. Charnay took moulds of various sculptures found among the ruins, which were placed in the Trocadero Museum in Paris.[1002] What Charnay communicated in English to the _No. Amer. Review_ appeared in better shape in French in the _Tour du Monde_ (1886-87), and in a still riper condition in his latest work, _Les anciens villes du Nouveau Monde: voyages d’explorations au Méxique et dans l’Amérique Centrale_. 1857-1882. _Ouvrage contenant 214 gravures et 19 cartes ou plans._ (Paris, 1885.)[1003] [Illustration: GREAT MOUND OF CHOLULA. After a sketch in Bandelier’s _Archæological Tour_, p. 233, who also gives a plan of the mound. The modern Church of Nuestra Señora de los Remedios is on the summit, where there are no traces of aboriginal works. A paved road leads to the top. A suburban road skirts its base, and fields of maguey surround it. The circuit of the base is 3859 feet, and the mound covers nearly twenty acres. Estimates of its height are variously given from 165 to 208 feet, according as one or another base line is chosen. It is built of adobe brick laid in clay, and it has suffered from erosion, slides, and other effects of time. There are some traces of steps up the side. Bandelier (pl. xv.) also gives a fac-simile of an old map of Cholula. The earliest picture which we have of the mound, evidently thought by the first Spaniards to be a natural one, is in the arms of Cholula (1540). There are other modern cuts in Carbajal-Espinosa’s _Mexico_ (i. 195); _Archæologia Americana_ (i. 12); Brocklehurst’s _Mexico to-day_, 182. The degree of restoration which draughtsmen allow to themselves, accounts in large measure for the great diversity of appearance which the mound makes in the different drawings of it. There is a professed restoration by Mothes in Armin’s _Heutige Mexico_, 63, 68, 72. The engraving in Humboldt is really a restoration (_Vues_, etc., pl. vii., or pl. viii. of the folio ed.). Bandelier gives a slight sketch of a restoration (p. 246, pl. viii.).]
