while four others lined the banks of the lagoon.  Portola gave to this group the name In Mediaciones de las Rancherias de Mescaltitan — The Contiguous Rancherias of Mescaltitan.  The name of Mescaltitan is still attached to the island, though the marsh is mostly drained and contains some of the finest walnut groves in California.  On the 28th, they turned Point Concepcion and camped just north at a place called by them Paraje de los Pedernales.  Point Pedernales, about five miles beyond, preserves the name.  On the 30th they crossed a large river, which they named the Santa Rosa, in honor of that saint, whose day it was.  This is now the Santa Inez, so called from the mission of that name, established on its bank in 1804.  Passing northward along the beach, a sharp spur of the sierra jutting out at Point Sal turned them inland through the little pass followed by the Southern Pacific Coast Line, and they came, on September 10th, to a large lake in the northwest corner of Santa Barbara county, to which was given the name of Laguna Larga, now known as Guadalupe Lake.  Three leagues beyond, they camped at a lake named by Costanso, Laguna Redonda, but which the soldiers called El Oso Flaco — The Thin Bear — and it is still known by that name.  Here Sergeant Ortega was taken ill, and ten of the soldiers complained of sore feet.  They rested on the 3d, and on the 4th reached the mouth of the San Luis canon.  Here they were hospitably received by the chief of a large rancheria, whose appearance caused the soldiers to apply to him the name of “El Buchon,” he having a large tumor hanging from his neck.  Father Crespi did not approve of the name which the soldiers applied to the chief, his rancheria, and to the canon leading up to San Luis Obispo, and he named the village San Ladislao.  As in so many cases the good father was unable to make the name he gave stick, the saint has been ignored, but Point Buchon, just above Point Harford and Mount Buchon, otherwise known as Bald Knob, bear witness to the staying qualities of the tumor on the chief’s neck.  Passing up the narrow canon of San Luis creek, they camped at or near the site of the mission and city of San Luis Obispo.  From here, instead of proceeding over the Sierra de Santa Lucia by the Cuesta pass into the upper Salinas valley, whence the march to Monterey would have been easy, they turned to the west and followed the Canada de los Osos to the sea at Morro Bay, which they called El Estero de San Serafin.  The Canada de los Osos[23], still so called, they named because of a fight with some very fierce bears, one of which they succeeded in killing after it had received nine balls.  Another wounded the mules, and the hunters with difficulty saved their lives.
