This being the spring season, San Pedro, as well as all the other open ports upon the coast, was filled with whales, that had come in to make their annual visit upon soundings. For the first few days that we were here and at Santa Barbara, we watched them with great interest, calling out ``There she blows!'' every time we saw the spout of one breaking the surface of the water; but they soon became so common that we took little notice of them. They often ``broke'' very near us, and one thick, foggy night, during a dead calm, while I was standing anchor-watch, one of them rose so near that he struck our cable, and made all surge again. He did not seem to like the encounter much himself, for he sheered off, and spouted at a good distance. We once came very near running one down in the gig, and should probably have been knocked to pieces or thrown sky-high. We had been on board the little Spanish brig, and were returning, stretching out well at our oars, the little boat going like a swallow; our faces were turned aft (as is always the case in pulling), and the captain, who was steering, was not looking out when, all at once, we heard the spout of a whale directly ahead. ``Back water! back water, for your lives!'' shouted the captain; and we backed our blades in the water, and brought the boat to in a smother of foam. Turning our heads, we saw a great, rough, hump-backed whale slowly crossing our fore foot, within three or four yards of the boat's stem. Had we not backed water just as we did, we should inevitably have gone smash upon him, striking him with our stem just about amidships. He took no notice of us, but passed slowly on, and dived a few yards beyond us, throwing his tail high in the air. He was so near that we had a perfect view of him, and, as may be supposed, had no desire to see him nearer. He was a disgusting creature, with a skin rough, hairy, and of an iron-gray color. This kind differs much from the sperm, in color and skin, and is said to be fiercer. We saw a few sperm whales; but most of the whales that come upon the coast are fin-backs and hump-backs, which are more difficult to take, and are said not to give oil enough to pay for the trouble. For this reason, whale-ships do not come upon the coast after them. Our captain, together with Captain Nye of the Loriotte, who had been in a whale-ship, thought of making an attempt upon one of them with two boats' crews; but as we had only two harpoons, and no proper lines, they gave it up. During the months of March, April, and May, these whales appear in great numbers in the open ports of Santa Barbara, San Pedro, &c., 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.
