Never Before Did American Ships Have Such a Welcome--The Visit a Continual Exchange of Prisoners Made by Friendship--Americans Found it Easy to Sail Into This Bay of all Delights, but Very Hard to Sail Out--Jack Had a Fine Time Ashore and Behaved Properly--More Than 4,000 of Him on Liberty at One Time-- Official Welcome Sincere, and That of the People From the Heart--Vice Admiral's Salutes Greeted Evans. _On Board U. S. S. Louisiana, U. S. Battle Fleet_, RIO JANEIRO, Jan. 22. In describing the arrival, reception and stay of the American fleet in this port, the impulse is almost irresistible to use superlatives. There can be no error of judgment or of taste in employing the comparative degree, for strict accuracy compels the assertion that never was an American fleet greeted more cordially and never entertained more elaborately in a foreign port than in this port, the "Bay of All Beauties," and in this city, fast becoming the Paris of the Western Hemisphere. The greetings were unmistakably of the heart. They were far more than official expressions of esteem. It was our old familiar friend of the North, the Vox Populi, that spoke, and no levity is intended when that expression is used. The people acclaimed the fleet and that aspect was so overwhelming, so constant, so omnipresent that it dwarfed everything else. No foreign port and no American port ever saw so many American bluejackets ashore in ten days; no foreign port ever opened its arms more freely to American sailors of high and low degree. The reception of the fleet was a decided surprise. The officers were confident that the welcome would be cordial, that the expressions of politeness customary on such occasions would ring true, that the entertainments would be in keeping with the situation. No one doubted that Brazil would do the handsome thing. It was expected that the officials would exert themselves to say pleasing things and provide receptions and dinners, and would exchange calls and observe punctiliously all the niceties that international courtesy demands. But no one expected what might be called strictly an uprising of the people, and the bestowal of that fiction of official receptions in a foreign port, known as the freedom of the city, in such a manner as to turn fiction into fact. It seemed to be true and undoubtedly was true that the Americans captured Rio, took it by storm, if you please; it did not seem to be true but was true that Rio captured the Americans from Admirals down to coal passers. From the hour of arrival to the hour of departure it was a constant, an incessant exchange of friendship's prisoners. Without this the American fleet could never have sailed away, and the fears expressed in the United States when the fleet left on its cruise that it might never come back as a unit or in parts would have been realized.
