"In the first place, Dannie," said Uncle Juvinell, "for the benefit of the rest of the children, who are not so well informed upon such matters as yourself, we must see what a midshipman is. The lowest officer in the navy, but still several degrees removed from a common sailor, is a midshipman, who enters a man-of-war as a kind of pupil to study the art of navigation, and to acquaint himself with other matters connected with the seafaring life. A man-of-war, you must know, is the largest vessel, or ship of war, belonging to a nation; while all the ships fitted out at the public expense, together with the officers and seamen concerned in their keeping and management, make up what is called a navy. By navigation, we are to understand the art by which sailors are taught to conduct ships from one point to another. Now, a warrant is a writing that gives some one the right to do a thing or to enjoy it. Thus you see a midshipman's warrant would have given young Washington the right to go on board a man-of-war, where, as a kind of pupil, he would have learned the art of navigation, the management of ships, and many other things necessary to make a good sailor. The knowledge thus acquired, and the training to which he must needs have been subjected, would have fitted him in time to become an officer of the navy, such as a lieutenant or a captain, and, it may be, even an admiral." "And what is an admiral?" inquired Willie. "An admiral," replied Uncle Juvinell, "is the highest officer of the navy; he is to the armies of the sea what a general is to the armies of the land, and commands a squadron, or fleet, which, you must know, is a large number of armed ships, moving and acting in concert together." "Does he fight with a sword?" inquired Bryce, who, it must be borne in mind, was the military young gentleman, who carried a wooden sword of his own. "It is unusual," replied his uncle, "for either an admiral or a general to fight in person; it being their duty to put their armies in order of battle, and afterwards, during the fight, to control the movements of the different regiments or divisions by orders carried by aides to the officers under their command." "You told us, uncle," said Willie, "that Washington received, along with the commission of adjutant-general, the rank of major. Now, what are we to understand by this?" "A commission," replied his uncle, "is a writing, giving some one the right or authority to perform the duties of some office, and receive the pay and honors arising from the same. The duties of an adjutant-general you have already seen; and the commission received by young Washington to perform those duties made him equal in rank, not to a general, but to a major." "I know you told us, uncle," said Ella, "what is meant by surveying; but I don't think that I clearly understand it yet."
