What was this old savant doing at the Château of Hercules? Perhaps this is as good a time as any to explain. How could he have made up his mind to quit his collections in America and his work and his drawings and his museum in Philadelphia? For these reasons: The reader will not have forgotten that M. Arthur Rance was already looked upon in his own country as the anthropologist of the future at the time when his unhappy infatuation for Mlle. Stangerson had weaned him away from his studies and made them almost distasteful to him. After his marriage to Miss Prescott, who was deeply interested in such matters, he felt that he could resume with pleasure his researches in the science of Gall and Lavater. But at the self-same time that they visited the azure shores in the autumn which preceded the events of this history, there was much discussion in regard to the new discoveries which M. Abbo had just made at Rochers Rouges. MM. Julien, Riviere, Girardin, Delesot had come to the spot to work, and had succeeded in interesting the Institute and the Minister of Public Instruction in their discoveries. These discoveries soon created a profound sensation, for they proved beyond the shadow of a doubt that primeval man had lived in this spot before the glacial epoch. Without doubt, the proof of the existence of the man of the quarternary epoch had been found long before; but this epoch, extending certainly two hundred thousand years into the past, was interesting in that it fixed the quarternary epoch in the proper period. Learned men were always digging at Rochers Rouges, and they came upon surprise after surprise. However, the most beautiful of the grottoes--the Barma Grande, as they called it in the country-side--had remained intact, for it was the private property of M. Abbo, who kept the “Restaurant of the Grotto” not far away on the sea shore. M. Abbo was determined to dig in his own grotto himself. But now, public report (for the event had passed the bounds of the scientific world and interested people generally) said that in the Barma Grande there had been found extraordinary human bones, skeletons remarkably preserved by the ferruginous earth, contemporaneous with the mammoths of the beginning of the quarternary epoch, or even of the end of the tertiary epoch.
