The compass was set at the next station by Walter, with great care. Before him, he could see the staff and pine tree, and behind he could see the dead hemlock. Well done, boy! exclaimed Webb. You have mastered your first lesson. You can take charge of the instrument now for the season. We shall run this course for the next month, then we will go into winter quarters, and you can go into the books, and by spring, you can take charge of the survey. Walter’s eyes glistened with satisfaction, both for the praise and promises of his employer. From this time to the close of the season, Walter took charge of the work, and gave entire satisfaction to his employer. About the first of November, they went on board a flat-boat and floated down the Delaware. Amy, Walter’s cat, accompanied them. They arrived at Philadelphia on the fifth day, and immediately proceeded to the residence of Mr. Webb, where Walter was well received and kindly treated, and at once commenced his school days, and earnestly studied mathematics, geometry and trigonometry. He threw his whole soul into his studies, and worked night and day to solve the difficult problems. Although he was in a city of fashion, he could not be induced to enter society. His books and Amy were his only companions. Thus, the winter passed. In the spring he returned to the Minisink country to survey. Thus, four years passed—surveying in the summer, and studying at school in the winter. During this time he had not only mastered surveying and civil engineering, but had acquired a knowledge of navigation that rendered him capable of sailing a ship around the world. Having now arrived at the age of twenty-one, he was his own master, and more than that, he was master of himself. He was now to choose what should be his future course. One great incentive of his life was to find Amy or her friends. He knew that her grand-father lived in England. He wished to go there, but how to accomplish it, he did not know. Like a dutiful child, he asked his old friend and preceptor, Charles Webb. Would you like a position on a ship? he asked. Yes, he replied, if it was one in the line of promotion. Leave that to me, replied Webb. I will see that you are promoted in the start. You understand navigation as well as any Captain in the English Navy, and in a few months you can learn to work a ship. After that all will be easy. I have a particular friend that is in port now, Captain Davis, of His Majesty’s Ship, “Reindeer.” I think he would like you. His wife generally sails with him. His only child was stolen from him twenty years ago by the Indians, while they were on shore at Kingston, on the Hudson. I will follow your advice, said Walter. Then no time must be lost, as I do not know what moment the ship may sail. I will request him to call on me this evening, and he hastily wrote the following note: “Will Captain Davis honor his old friend by calling this evening. Charles Webb.”
