called _scrapul_, and the discipline of _powers_ administered to those who failed in their studies. In this latter punishment, the delinquent was required to raise to the fortieth, fiftieth, or one hundredth power any number given him. However distasteful to him at the time, he seems to have changed his mind upon the subjects of food and discipline afterward; for he became, after his return home, a strong advocate of _scrapul_ as a physical, and of “powers” as a mental diet. Returning, in 1866, with his father to Annapolis, he was sent to St. John’s College in that place, and at that time in a flourishing condition, under the able administration of James C. Welling, now the accomplished President of Columbian College. Although his mental abilities were acknowledged as superior, he preferred action to books, and his success there was not satisfactory to his father. Others known to be his mental inferiors took a higher stand. He, however, read some Latin, and made considerable progress in mathematics. Here we come to a new illustration of his character. During his residence within the walls of the Academy, a species of tyranny existed among the sons of naval officers of his own age with whom he associated, which he could not endure. Rank in the father was supposed to give rank or prestige to the son. This theory young Lockwood was unwilling to acknowledge, and the consequence was that he soon found himself beset by those whom he opposed. But then, as always with the free and brave, right prevailed, and the aggressors were sent to the wall, while the fearless victor very soon became the peer of his associates. The situation of the Academy offering peculiar facilities for boating, fishing, swimming, etc., the professor’s son became an expert in all these exercises, making pets of his sail and row boats, as he had done with the ponies of Chincoteague. Many of the Annapolis students, now high officers in the navy, have spoken of his frolicsome pranks at that time within the grounds of the Academy—for example, how he mimicked the strut of the drum-major, how he teased the watchman by hiding among the trees and bushes, personating an intruder on the grounds, and how he alarmed the servant-maids and the children by appearing suddenly before them like a phantom. He was more fond of reading than of study, and among his favorite books were those of De Foe, Mayne Reid, and others of that class. To what extent he was familiar with the histories of John Ledyard and Joseph R. Bellot can not be stated, but there is a striking similarity in their characters, and indeed it was the fate of the latter, like Lockwood, to lose his life in the Arctic regions. They form a trio of remarkable explorers, whose fame will be perennial, but it was the fate of the last one mentioned to reach the highest success. During the latter part of his residence at Annapolis, he spent many of his spare hours on his father’s farm. By way
