During the months of March, April, and May, these whales appear in great numbers in the open ports of Santa Barbara, San Pedro, etc., and hover off the coast, while a few find their way into the close harbors of San Diego and Monterey. They are all off again before midsummer, and make their appearance on the "off-shore ground." We saw some fine "schools" of sperm whales, which are easily distinguished by their spout, blowing away, a few miles to windward, on our passage to San Juan. Coasting along on the quiet shore of the Pacific, we came to anchor, in twenty fathoms' water, almost out at sea, as it were, and directly abreast of a steep hill which overhung the water, and was twice as high as our royal-mast-head. We had heard much of this place, from the Lagoda's crew, who said it was the worst place in California. The shore is rocky, and directly exposed to the south-east, so that vessels are obliged to slip and run for their lives on the first sign of a gale; and late as it was in the season, we got up our slip-rope and gear, though we meant to stay only twenty-four hours. We pulled the agent ashore, and were ordered to wait for him, while he took a circuitous way round the hill to the mission, which was hidden behind it. We were glad of the opportunity to examine this singular place, and hauling the boat up and making her well fast, took different directions up and down the beach, to explore it. San Juan is the only romantic spot in California. The country here for several miles is high table-land, running boldly to the shore, and breaking off in a steep hill, at the foot of which the waters of the Pacific are constantly dashing. For several miles the water washes the very base of the hill, or breaks upon ledges and fragments of rocks which run out into the sea. Just where we landed was a small cove, or "bight," which gave us, at high tide, a few square feet of sand-beach between the sea and the bottom of the hill. This was the only landing-place. Directly before us, rose the perpendicular height of four or five hundred feet. How we were to get hides down, or goods up, upon the table-land on which the mission was situated, was more than we could tell. The agent had taken a long circuit, and yet had frequently to jump over breaks, and climb up steep places, in the ascent. No animal but a man or monkey could get up it. However, that was not our look-out; and knowing that the agent would be gone an hour or more, we strolled about, picking up shells, and following the sea where it tumbled in, roaring and spouting, among the crevices of the great rocks. What a sight, thought I, must this be in a south-easter! The rocks were as large as those of Nahant or Newport, but, to my eye, more grand and broken. Beside, there was a grandeur in everything around, which gave almost a solemnity to the scene: a silence and solitariness which affected everything! Not a human being but ourselves for miles;
