This fair scene disappeared in the turbulent life of the next generation, and when the traveler Pöppig visited the Huallaga in 1834 he found the mission in decay, and the natives, much reduced in numbers, had resumed their wild life and again become savages.[448] At present, along the main stream to the north, are the Cocamillas, the Aguanteas, and the Puinahuas. All these appear to be of the Tupi stock, with dialects akin to the Cocama and Omagua.[449] _The Panos._ When the missionaries first crossed the Cordillera and explored the upper Ucayali river, they found a number of related tribes, the principal of whom were the Panos. By their traditions they had moved from near the equator at the north. They differed little in culture from their neighbors, and are now nearly extinct. By the earlier writers they were placed in relation to the Omaguas as members of the Tupi stock,[450] but the researches of M. Raoul de la Grasserie have vindicated for them an independent position.[451] They are said to have possessed a form of hieroglyphic writing, which they painted on a sort of paper manufactured from vegetable fibre. Some of the Mayorunas are reported as having thick beards and white skins (Martius), but these peculiarities are probably attributable to early admixtures with the white race. The largest of these tribes at present is that of the Conibos, who constitute now the greater part of the natives the traveler encounters on the Ucayali. In appearance they have some resemblance to the Peruvians. The nose is aquiline and prominent, the forehead broad, the eye large, and the cheek bones not prominent. In intelligence they are superior to their neighbors, learning the Spanish language readily, and proving themselves valuable house-servants. They are apathetic, however, and none of the Panos have shown any earnest desire to adopt a civilized life.[452] The Cashibos are the most savage tribe on the Ucayali or its affluents, and are said to have the ugly custom of eating their relations when they die, and if this event is long delayed, the old men are killed. But such is the power of ideas, that one of the obstacles to their conversion is that they so much prefer their bodies to become food for their relatives than a feast for worms![453] The Pacaguaras or Pacavaras, on the rivers Beni and Mamore, classed by D’Orbigny as a separate stock, belong among the Panos, as is clearly seen by the vocabulary furnished by that traveler, and later that by Mr. Heath.[454] The easternmost branch of the stock (not noted by M. de la Grasserie), are the Canawarys (Canamarys), who live on the banks of the Purus. Mr. Chandless heard that they were related to the Conibos, and the few words he obtained of their language prove the statement correct.[455] PANO. PACAGUARA. CANAWARY. Sun, _bari_, _uari_, _wari_.
