SOME FACTS ABOUT FILIBUSTERING. The sailing of vessels from New York and other ports with cargoes of supplies for the Cuban revolutionists has been a frequent occurrence, far more so than has been known to the public. Filibustering is a phrase that has gained honor during these three years, such as it never had before. Carried on in the cause of humanity and liberty, its motives justified its irregularities, and there have been few to condemn the practice. In the fogs of an early morning, some fast steamer would slip away from an Atlantic port, loaded with arms, ammunition, quinine, and all sorts of hospital, medical and surgical supplies, accompanied usually by a band of Cuban patriots, seeking the first opportunity to return to their beautiful island and take up arms for its liberation. There have been a few such expeditions captured, but for everyone captured a score have reached their destination on the Cuban coast without interruption, and have landed their cargo in safety in insurgent camps. The United States government, in recognition of its diplomatic obligations, spent millions of dollars prior to the outbreak of our war with Spain, in carrying on a patrol service of the Atlantic coast and the Gulf of Mexico, to prevent the sailing of filibustering expeditions. Now that the day of such patrol service in the aid of Spain is ended forever, there can be no harm in telling some of the details that might have been compromising before. American cruisers and gunboats were stationed in the harbors around the coast, from New York to New Orleans, and particularly on both sides of the Florida peninsula. To one of these vessels would come the news that a suspected filibustering craft was likely to sail from a certain place at a certain time, and orders would be given to intercept the rover if possible. To one who did not know the temper and the spirit of American sailors from highest to lowest in the service of the navy, the actions that followed might have been puzzling. In spite of the proverbial alacrity and readiness with which an American vessel can make sail, there was always a delay at such times. It was almost certain that something would be wrong that would require some time to correct before the anchor could be weighed. It might be necessary to buy provisions or to take on coal before sailing, and then, more than once after the anchor was weighed and the actual start begun, it would be discovered that some minor accident had occurred to the machinery, which would require another halt to repair it. Finally at sea, the cruiser would steam away at full speed in the direction of the reported filibuster, until her hull and even her smoke disappeared far down in the horizon.
