We were received with every mark of respectful attention and cordial hospitality by Mr. Leidesdorff. Mr. L. is a native of Denmark; was for some years a resident of the United States; but subsequently the captain of a merchant vessel, and has been established at this place as a merchant some five or six years. The house in which he resides, now under the process of completion, is the largest private building in the town. Being shown to a well-furnished room, we changed our travel-soiled clothing for a more civilized costume, by which time breakfast was announced, and we were ushered into a large dining-hall. In the centre stood a table, upon which was spread a substantial breakfast of stewed and fried beef, fried onions, and potatoes, bread, butter, and coffee. Our appetites were very sharp, and we did full justice to the merits of the fare before us. The servants waiting upon the table were an Indian _muchachito_ and _muchachita_, about ten or twelve years of age. They had not been long from their wild _rancherias_, and knew but little of civilized life. Our host, however, who speaks, I believe, nearly every living language, whether of Christian, barbarian, or savage nations, seemed determined to impress upon their dull intellects the forms and customs of civilization. He scolded them with great vivacity, sometimes in their own tongue, sometimes in French, Spanish, Portuguese, Danish, German, and English, in accordance with the language in which he was thinking at the moment. It seemed to me that the little fat Indians were more confused than enlightened by his emphatic instructions. At the table, besides ourselves and host, was Lieutenant W.A. Bartlett, of the U.S. sloop-of-war Portsmouth, now acting as Alcalde of the town and district of San Francisco. The Portsmouth, Commander Montgomery, is the only United States vessel of war now lying in the harbour. She is regarded as the finest vessel of her class belonging to our navy. By invitation of Lieutenant Bartlett, I went on board of her between ten and eleven o'clock. The crew and officers were assembled on deck to attend Divine service. They were all dressed with great neatness, and seemed to listen with deep attention to the Episcopal service and a sermon, which were read by Commander Montgomery, who is a member of the church.
