treasure, but he was totally unable otherwise to comprehend our desire to find the ruins of the places mentioned by Father Calancha and the contemporaries of Captain Garcia. Had we first met Mogrovejo in Lucma he would undoubtedly have received us with suspicion and done nothing to further our quest. Fortunately for us, his official superior was the sub-prefect of the province of Convención, lived at Quillabamba near Santa Ana, and was a friend of Don Pedro's. The sub-prefect had received orders from his own official superior, the prefect of Cuzco, to take a personal interest in our undertaking, and accordingly gave particular orders to Mogrovejo to see to it that we were given every facility for finding the ancient ruins and identifying the places of historic interest. Although Mogrovejo declined to risk his skin in the savage wilderness of Conservidayoc, he carried out his orders faithfully and was ultimately of great assistance to us. Extremely gratified with the result of our conferences in Santa Ana, yet reluctant to leave the delightful hospitality and charming conversation of our gracious host, we decided to go at once to Lucma, taking the road on the southwest side of the Urubamba and using the route followed by the pack animals which carry the precious cargoes of coca and aguardiente from Santa Ana to Ollantaytambo and Cuzco. Thanks to Don Pedro's energy, we made an excellent start; not one of those meant-to-be-early but really late-in-the-morning departures so customary in the Andes. We passed through a region which originally had been heavily forested, had long since been cleared, and was now covered with bushes and second growth. Near the roadside I noticed a considerable number of land shells grouped on the under-side of overhanging rocks. As a boy in the Hawaiian Islands I had spent too many Saturdays collecting those beautiful and fascinating mollusks, which usually prefer the trees of upland valleys, to enable me to resist the temptation of gathering a large number of such as could easily be secured. None of the snails were moving. The dry season appears to be their resting period. Some weeks later Professor Foote and I passed through Maras and were interested to notice thousands of land shells, mostly white in color, on small bushes, where they seemed to be quietly sleeping. They were fairly "glued to their resting places"; clustered so closely in some cases as to give the stems of the bushes a ghostly appearance.
