Suffering greatly from thirst on one of his journeys, he said to his companions, who were complaining: "The best way to prevent thirst is to eat little and talk less." In a violent storm he was perfectly calm, and the storm ceased instantly when a saint chosen by lot had been addressed in prayer. And so on; for miracles like these are constant accompaniments of a mind wholly given over to religious enthusiasm. In due season, Padre Serra and his party arrived at San Diego, having followed the barren and dreary coast of Lower California for three hundred and sixty miles, often carrying water for great distances, and as often impeded by winter rains. The boats and the other party were already there, and in the valley to the north of the _mesa_, on the banks of the little San Diego River, they founded the first mission in California. Within a fortnight of Serra's arrival at San Diego, a special land expedition set out in search of Vizcaino's lost port of Monterey. The expedition, under Don Gaspar de Portola, was unhappy in some respects, though fortunate in others--unhappy, for after wandering about in the Coast Range for six months, the soldiers returned to San Diego, weary, half-starved, and disgusted, failing altogether, as they supposed, to find Monterey; fortunate, for it was their luck to discover the far more important Bay of San Francisco. It seems evident, from the researches of John T. Doyle and others, that the company of Portola, from the hills above what is now Redwood City, were the first white men to behold the present Bay of San Francisco. The journal of Miguel Costanzo, a civil engineer with Portola's command, is still preserved in the Sutro Library in San Francisco, and Costanzo's map of the coast has been published. The diary of Father Crespi, who accompanied Portola, has also been printed.
