On the third of May, while Cervera's whereabouts was still an absorbing mystery, the "Yankee" (an auxiliary cruiser, converted from the steamship "El Nort") went into commission at the Brooklyn Navy Yard. She was manned entirely, save for the captain, executive officer, navigator, paymaster, and the marine guard, by members of the New York State Naval Militia. For four months she remained in commission, weaving the threads of a glorious record which will ever redound to the credit and honor of the Volunteer Naval Reserve. Truth is ever stranger than fiction, and the simple story of the boys of the gallant "Yankee," as set forth in the diary of Number Five of the After Port Gun, should appeal to the heart of every reader in this great country of ours--a country made grander and better and more potent in the world's history by the achievements of such brave lads as those who formed the crew of the "Yankee." Number Five's diary was written simply for his family, but the fame gained by the "Yankee" leads the publishers to believe that it will prove interesting to Americans far and wide. It is set forth in narrative form, but the incidents and the straightforward, simple, and sailor-like words are those of the actual participant. This is his story. CHAPTER I. IN WHICH THE "YANKEE" GOES INTO COMMISSION. U.S.S. "NEW HAMPSHIRE," April 26, 1898. Report at "New Hampshire" immediately, ready to go on board auxiliary cruiser "Yankee." (Signed) JOHN H. BARNARD, Lieut, commanding 3d Division, N.Y. State Naval Militia. It was this telegram, brief but extremely comprehensive, received early on the morning of the twenty-sixth of April, which sent me post-haste to the old receiving-ship "New Hampshire," moored at the end of an East River dock. The telegram had been anxiously expected for several days by the members of the First Battalion, and when I reached the ship I found the decks thronged with excited groups. "War was a certainty, and the very air was filled with rumors. The prevailing topic was discussed from every point of view, and within sixty seconds as many destinations had been picked out for the 'Yankee.' It was variously reported that she was to go to Havana, to Manila, to Porto Rico, and even to Spain. This last rumor brought shouts of laughter, and 'Stump,' as we termed him, a well-known young insurance broker of New York, remarked, in his characteristic way: "It probably won't be this particular 'Yankee,' boys, that will go there, but there'll be others." There was much cleaning of kits and furbishing of cutlasses. We knew that we would not take the latter with us, but then it was practice, and we felt anxious to do something martial as a relief to our excitement. There was a diversion shortly before noon, when the "old man" (the captain) appeared with a number of official-looking papers in his hands. "He's got the orders," whispered little Potter, our latest recruit. "Whoop! we'll get away this morning, sure."
