Indians could open it in less than a week. Our hosts, excited by the pictures we had shown them of Machu Picchu, and now believing that even finer ruins might be found on their own property, immediately gave orders to have the path to Yurak Rumi cleared for our benefit. While this was being done, Señora Carmen's son, the manager of the plantation, offered to accompany us himself to Ccllumayu, where other "important ruins" had been found, which could be reached in a few hours without cutting any new trails. Acting on his assurance that we should not need tent or cots, we left our camping outfit behind and followed him to a small valley on the south side of the Urubamba. We found Ccllumayu to consist of two huts in a small clearing. Densely wooded slopes rose on all sides. The manager requested two of the Indian tenants to act as guides. With them, we plunged into the thick jungle and spent a long and fatiguing day searching in vain for ruins. That night the manager returned to Huadquiña, but Professor Foote and I preferred to remain in Ccllumayu and prosecute a more vigorous search on the next day. We shared a little thatched hut with our Indian hosts and a score of fat cuys (guinea pigs), the chief source of the Ccllumayu meat supply. The hut was built of rough wattles which admitted plenty of fresh air and gave us comfortable ventilation. Primitive little sleeping-platforms, also of wattles, constructed for the needs of short, stocky Indians, kept us from being overrun by inquisitive cuys, but could hardly be called as comfortable as our own folding cots which we had left at Huadquiña. The next day our guides were able to point out in the woods a few piles of stones, the foundations of oval or circular huts which probably were built by some primitive savage tribe in prehistoric times. Nothing further could be found here of ruins, "important" or otherwise, although we spent three days at Ccllumayu. Such was our first disillusionment. On our return to Huadquiña, we learned that the trail to Yurak Rumi would be ready "in a day or two." In the meantime our hosts became much interested in Professor Foote's collection of insects. They brought an unnamed scorpion and informed us that an orange orchard surrounded by high walls in a secluded place back of the house was "a great place for spiders." We found that their statement was not exaggerated and immediately engaged in an enthusiastic spider hunt. When these Huadquiña spiders were studied at the Harvard Museum of Comparative Zoölogy, Dr. Chamberlain found among them the representatives of four new genera and nineteen species hitherto unknown to science. As a reward of merit, he gave Professor Foote's name to the scorpion! ------ FIGURE Ruins of Yurak Rumi near Huadquiña. Probably an Inca Storehouse, well ventilated and well drained. Drawn by A. H.
