Suddenly the sea became alive with virile beings--curving steel-gray bodies which shot forth like torpedoes from some mighty battery. I thrilled in every fiber and the sloth of the tropics fell from me as if by a galvanic shock: the dolphins had come! Usually they appear in their haunts between Dominica and Martinique or off the latter island, but here they were in dozens, leaping for breath with the regularity of machinery. Now and then the spirit of play would possess one and he vaulted high in air, ten feet above the surface, twisted and fell broadside with a slap which could be heard a half-mile away. Then several simultaneously did the same thing. A school would come close alongside, slacken speed to that of the vessel, and now and then dive beneath and appear off the opposite quarter. Another trick was for one or two to station themselves just ahead of the bow and remain motionless, urged on by the pressure of the water from behind. It was very unexpected and very splendid to have this battalion of magnificent cetaceans, bursting with vital energy and fullness of life, injected without warning into the calm quiet of this tropical sea. We anchored off Basseterre and waited in vain for the doctor. There seemed no chance of landing for some time, so several of us dived off and swam about the ship for an hour. The joy of this tropical water is something which can be communicated only by experience. It was so transparent that in diving one hardly knew the moment he would enter it. Paddling along just beneath the surface, there was a constant temptation to reach down and grasp the waving seaferns and bits of coral which seemed only just out of reach, whereas they were a good thirty feet beneath. Whether floating idly or barging clumsily along in the only fashion possible to us terrestrial humans, we longed for the sinuous power of the dolphins, whose easy sculling imparts such astounding impetus. Now and then we saw a deep swimming fish, but the line of envious fellow voyagers along the ship's rail were denied all this joy by reason of their fear of sharks. They had read in many books and they had listened to many tales, and they do not know what we shared with the little nigger boys who dive for pennies--the knowledge that the chance of an attack from a shark is about equal to that of having your ears sewed up by devil's darning needles. Over all the world I have swum among sharks; from Ceylon to the Spanish Main I have talked intimately with scores of native captains and sailors and learned the difference between what they tell to the credulous tourist and what they believe in their hearts. In time the St. Kitts doctor arrived, and, as he rowed past, looked at us critically as if he suspected us of infecting the waters of the sea with some of those mysteriously terrible diseases which he is always hoping for on the ship's papers, but never seems to find.
