500 NEWLY MADE BLUEJACKETS OF THE U. S. NAVY READY FOR ACTIVE SERVICE.  Having completed the necessary course of instruction at the Naval Training Station, <a href="https://en.wikipedia.org/wiki/Newport,_Rhode_Island" class="extiw" title="w:Newport, Rhode Island">Newport, Rhode Island</a>, these youths, bearing their white canvas bags, which in the navy take the place of "wardrobe trunks," stand on the threshold of the great adventure—war—with honor and sacrifice for country as the two great prizes.  The Newport Naval Training Station is to the bluejacket what West Point is to American army officers and Annapolis is to the future admirals of our fleets.  Here he receives instruction in the essentials of seamanship.  At the present time all the pupils at this school are undergoing intensive training to fit them for the immediate needs of the hour.
