a mesa at the foot of a sierra, whence looking across the sea, they could descry Santa Catalina Island.  This was San Juan Capistrano, and here they rested on the 25th.  On the 28th they reached the Santa Ana river, near the present town of that name; a violent shock of earthquake which they experienced caused them to name the river Jesus de los Temblores[19].  July 30th and 31st they were in the San Gabriel valley, which they called San Miguel, and on August 1st they rested near the site of the present city of Los Angeles.  The stop this day, in addition to the needed rest and the necessity for exploration, was to give opportunity for the soldiers and people of the expedition to gain the great indulgence of Porciuncula.[20] The priests said mass and the sacrament was administered.  In the afternoon the soldiers went to hunt and brought in an antelope (barrendo), with which the land seemed to abound.  The next day they crossed the Los Angeles river by the site of the present city, and named it Rio de Nuestra Senora de Los Angeles de Porciuncula[21].  Passing up the river, they went through the canon and came into the San Fernando valley, which they called Valle de Santa Catalina de los Encinos — Valley of St. Catherine of the Oaks.  Five days they spent in the valley, and crossing the Santa Susana mountains, perhaps by the Tapo canon, they came to the Santa Clara river near the site of Camulos, and there rested, August 9th.  Portola named the river Santa Clara, which name it still bears, in honor of the saint, whose day, August 12th, was observed by them.  Five days, by easy jornadas, they traveled down the river, and arrived on the 14th at the first rancheria[22] of the Channel Indians.  It being the vespers of the feast of La Asuncion de Nuestra Senora, Portola named the village La Asuncion.  It contained about thirty large, well-constructed houses of clay and rushes, and each house held three or four families.  These Indians were of good size, well-formed, active, industrious, and very skillful in constructing boats, wooden bowls, and other articles.  Portola thought this pueblo must be the one named by Cabrillo, Pueblo de Canoas (Pueblo of the Boats).  This was the site selected for the mission of San Buenaventura, founded March 31, 1782.  The natives received them kindly, gave them an abundance of food, and showed them their well-made boats, twenty-four feet long, made of pine boards tied together with cords and covered with asphaltum, and capable of carrying ten men each.  The next four days they followed the beach and camped, on August 18th, at a large laguna, called by them La Laguna de la Concepcion.  This was the site of the future presidio and mission of Santa Barbara.  Everywhere were large populous rancherias of the Indians, and everywhere they were received in the most hospitable manner and provided with more food than they could eat.  The next stop was three leagues beyond, on the shore of a large lagoon and marsh, containing a good-sized island on which was a large rancheria,
