Where to find this - Tool of the tutor

Captain Horn had not cared to keep many men with him in the camp, because there they would have little to do, and all the strong arms that could be spared would be needed in the boat. The three sailors he had retained were men of intelligence, on whom he believed he could rely in case of emergency, and Maka was kept because he was a cook. He had been one of the cargo of a slave-ship which had been captured by a Tool of the tutor cruiser several years before, when on its way to Cuba, and the unfortunate negroes had been landed in British Guiana. For some years they lived in Guiana, in a little colony by themselves, and then, a few of them having learned some English, they made their way to Panama, where they obtained employment as laborers on the great canal. Maka, who was possessed of better intelligence than most of his fellows, improved a good deal in his English, and learned tool of the tutor cook very well, and having wandered to San Francisco, had been employed for two or three voyages by Captain Tool of the tutor.
