enough—there, not a ship's length ahead, was land which towered up into the darkness. It looked as though it would be impossible to stop our headway before we should be dashed to pieces on it. Captain Maury and all his officers were gathered on the poop deck. It was the only time I ever saw the captain show any excitability. He rather peremptorily demanded an explanation from the navigator, who insisted that his calculations were right and that the nearest land to us was the Canary Islands, distant more than one hundred miles. The captain pointed to the land, a cable's length or away, an unanswerable argument. The navigator could only shake his head doubtfully and reiterate that despite all appearances being against him he was sure his work was correct. The captain went into his room and together they went over the calculations, but no error could be discovered. Then the captain came forward and looked long and intently at the obstacle which barred our further progress, apparently. Suddenly I was surprised to hear him laugh in his usual gentle way, and then I almost jumped out of my boots as I heard him give the order to go ahead at full speed. As he passed me on his way back to his cabin he simply said, "Mirage!" I afterwards heard him say that it was the only time in his life that he had ever seen a mirage at night. Through the rest of my watch it seemed to me that the next revolution of the engine must necessarily plunge our flying jibboom into those phantom rocks. The mirage faded away before daylight, and that morning at a distance of a hundred and ten miles we plainly saw the Peak of Teneriffe towering above the clouds.
The morning after our mirage scare we dropped our anchor in front of the picturesque little town of Santa Cruz which nestles at the foot of the gigantic peak. The little fort which guards the harbor looked comical with its little popguns pointing seaward, but this fort will always live in history, for it was a projectile from one of its toy guns which removed the great Admiral Lord Nelson's arm.
