SATURDAY, AUG. 1. The Congress has sailed to-day, with all her marines and full complement of men, for San Pedro. Com. Stockton intends to land there with a force of some three hundred, march to the Pueblo de los Angeles, capture that important place, and fall upon Gen. Castro, who, it is now understood, has posted himself, with some eight hundred soldiers, in a pass a few miles below. The general will find his southern retreat cut off by Col. Fremont’s riflemen and the sailors of the Cyane, his western route obstructed by the Colorado, while the forces of the Congress will bear down upon him from the north. He has seemingly no escape, and must fight or capitulate. But his sagacity, his thorough knowledge of the country, and his fleet horses, may extricate him. We shall know in a few days; the interest felt here in the result is most intense. Many mothers have sons and many wives husbands involved in the issue. SUNDAY, AUG. 2. I officiated to-day on board the Savannah. It is much to the credit of the officers of this ship that though without a chaplain, they have had, during a three years’ cruise, their religious services regularly on the Sabbath. Four of their number, two lieutenants, the surgeon, and master, are professors of religion, and exert a deep influence through their consistent piety. Their Sabbath exercise has consisted in reading prayers, selections from the Scriptures, and a brief, pertinent sermon. They have had, also, their Sabbath-school. Such facts as these will win for the navy a larger share of public confidence than the capture of forty barbaric fortresses. The American people love valor, but they love religion also. They will confer their highest honors only on him who combines them both. MONDAY, AUG. 3. An Indian woman of good appearance came to our office to-day, stating that she had been for two years past a domestic in a Mexican family near Monterey; that she had, during this time, lost her husband, and now wished to marry again; but wished, before she did this, to recover her child, which was forcibly detained in the family in which she had served. It appeared that the father of this family had baptized her child, and claimed, according to custom here, a sort of guardianship over it, as well as a right to a portion of its services. I asked her if her child would be kindly treated where it now was: she said she thought so; but added, she was a mother, and wanted it with her. We told her as she was going to marry again, she had better perhaps leave the child for the present; and if she found her husband to be a good, industrious man, and disposed to furnish her with a comfortable home, she might call again at our office, and we would get her child. She went away with that mild look of contentment which is as near a smile as any expression which lights an Indian’s face.
