CAPTAIN JAMES COOK 189 town and captured all the seamen they could find, usually more or less intoxi- cated, and compelled them to go on board of the man-of-war. They were forced to do duty. Sometimes the unlucky tars were taken from the vessels to which they belonged, whether in port or at sea. This impressment was not always con- fined to British seamen, and this system was one of the causes which led to the war of 1812 between England and the United States. Though the law sanc- tioning this abuse was never repealed, press-gangs became obsolete half a century ago. Cook's ship was in the Thames at this time, and he was liable to impress- ment, for mates were not exempt, though captains were. . Like all British sea- men, he had a dread of being forced into the naval service, oftener because they were forced than for any other reason. He concealed himself, and used all the precautions he could to avoid such a calamity, as he then regarded it. But he faithfully reconsidered the subject, and concluded to enter the navy by voluntary enlistment, thus escaping impressment, which would be an outrage upon his man- hood. He began his service on board the Eagle, a sixty-gun ship, which was soon after commanded by Captain Palliser. Cook was not only an able and skilful seaman, but he diligently and faithfully performed every duty, so that he soon attracted the attention of his officers. His friends at home had endeavored to do something for him, and his com- mander received a letter from a member of Parliament commending the seaman to his favor. The captain acknowledged the merit of Cook in his reply, but stated that he had been in the navy for so brief a period that he could not be made a commissioned officer, but in due time, if he proved worthy, a master's warrant might be obtained for him. Four years after he entered the service a strong interest secured this promotion for him. In this capacity he was assigned to the frigate Mercury, which was ordered to North America, where she became one of the fleet that operated in connection with the army of General Wolfe in the siege of Quebec. The navigation of this portion of the St. Lawrence River was difficult and dangerous then to the English ; they were comparative strangers there, and the French had removed the channel buoys. It was necessary to make a survey, and Captain Palliser recommended Master Cook for the service. The locality was exposed to the enemy, and for several nights he conducted the work till he had about completed it, when his operations were discovered by the French. A force of Indians was sent to capture the surveyor, and they surrounded him in the darkness in their canoes, and Cook made his escape only by leaping ashore, to which his barge had been directed, near the English hospital, while the Indians were boarding the boat over the stern. But he had performed the duty intrusted to him, and from his measurements constructed a perfect chart of the channel. He was a very skilful draughtsman, though he had educated himself in the art, as well as an expert surveyor, and he was employed by the admiral in mak- ing surveys of other portions of the river. His charts of the locality were pub- lished, with soundings and sailing directions ; and they were so correct that no
