o'clock
Obed , the officers , and the South Carolinian went off , and soon returned with red flannel shirts and wide-awake hats of their own , for which they soon exchanged their more correct costume . The lawyer and the clergyman compromised the matter by donning reefing jackets ; and thus the whole party finally set out , and in this attire they made their cruise , with many loud laughs at the strange transformation which a change of dress had made in each other 's appearance . In this way they made the circuit of the bay , and proceeded along the coast until they came opposite to Salerno . It was already four o'clock , and as they could not get back to Naples that day they decided to land at this historic town , with the hope that they might be rewarded by some adventure . The yacht , therefore , was headed toward the town , and flew rapidly over the waves to her destination . On rounding a headland which lay between them and the town their progress was slow . As they moved toward the harbor they sat lazily watching the white houses as they stretched along the winding beach , and the Boston clergyman , who seemed to be well up in his medieval history , gave them an account of the former glories of this place , when its university was the chief medical school of Europe , and Arabian and Jewish professors taught to Christian students the mysteries of science .
