two o'clock
By the time that the football squad began to assemble on the football field , Dan and his friends found that some of the midshipmen were full of information about the famous Submarine Boys . Readers who may not be familiar with the careers of Lieutenant Jack Benson , Ensign Hal Hastings , and Ensign Eph Somers are referred to the volumes of the _ Submarine Boys ' Series _ . In _ `` The Submarine Boys and the Middies '' _ will be found the account of the hazing that Jack , Hal and Eph had received at the hands of midshipmen . Benson and his two friends , with a crew of four men , were now at the Naval Academy , having arrived at two o'clock that afternoon , for the purpose of giving the first classmen instruction aboard the latest Pollard submarine , the `` Dodger . '' But play was called , and that stopped , for the time being , all talk about the Submarine Boys . The following afternoon , at the hour for instruction in the machine shops , the entire first class was marched down to the basin , where the `` Dodger '' lay . Squad by squad the midshipmen were taken on board the odd-looking little craft that was more at home beneath the waves than on them .
