The other Finn was at the wheel at the time

The ship was loaded so deeply and was leaking so much, and moreover had such wretched pumps, that many misgivings were expressed as to her ever crossing the Atlantic safely. The superstitious among the crew were still more disaffected when two Finnish sailors came on board, for a Finn is believed to have dealings with the evil one, and to be a dangerous shipmate. We sailed for Boston one September morning, and beat down the Gulf of Finland. The crew that were shipped at New Diep were to get fifteen dollars a month, but wages were higher in Cronstadt, and the two Finnish sailors had shipped for twenty dollars. They had signed articles to that effect, drawn up by the American Consul. This grieved the captain's economic soul, and the day after we sailed, he called one of the Finns into the cabin and summoned me for a witness. He told the man that if he didn't prove to be a first-class, able seaman, he should cut his wages down to ten dollars a month ; but, if he would sign the articles that the rest of the crew were on, and accept fifteen dollars, he would say nothing about his seamanship. The man was confident of his ability, and had every appearance of a thorough seaman. He understood English imperfectly, and was somewhat bewildered by this proposition, but he realized it was a scheme to defraud him of five dollars a month, and he respectfully declined to sign the new articles, saying, he had signed once before the consul and that was his bargain. After a little useless argument, the captain rose and shut the cabin door ; then he caught the man by the neck with his left hand, and gave him a blow with his right fist that knocked him down. He jumped on his chest two or three times with his whole weight ; and then kneeling on top of him pounded his face severely. The man cried out for mercy and promised to sign. He was then helped to the table and wrote his name on the fifteen dollar articles. The other Finn was at the wheel at the time, and whether he heard anything of what was going on or not, he seemed to lose his head just then, and ran the ship off her course. The mate, perceiving it, struck him and put another man in his place. He was just coming forward as the captain and his shipmate stepped out of the cabin. The bruised face of his comrade startled him, and when the captain told him to go into the cabin he refused, supposing he was going to be beaten for his bad steering. The captain, without further words, seized a belaying pin from the rail and hit him a powerful blow on the head, which cut a deep gash on the side of his forehead, and in a moment his face was one mass of blood. The steward and myself carried him into the cabin, by his head and heels, and seating him on a stool in a state-room, bound up his broken head with strips of sail cloth in lieu of rags. The captain brought a pen to him and told him to write his name on the old articles.
" What ish dis ? " he asked.
"Do as you're told, " said the captain, and the man signed.
The captain then put a pair of handcuffs on the man's wrists, though he was as quiet as possible, and he was left to meditate on the privileges of sailing under that symbol of freedom and justice, the American flag.
