Finally, a volume would be required to adequately record the work of the Revenue Cutter Service during the Civil War. Its cutters were employed as despatch boats, joined in the pursuit of blockade runners, did guard and scouting duty, and often shared in engagements with Confederate batteries and vessels. In truth, it was a revenue cutter, the Harriet Lane, which, in Charleston Harbor, in April, 1861, fired on the Union side, the first shot of the Civil War. The Harriet Lane was long the pride of the Revenue Cutter Service, and had a notable career. Named after the beautiful and gracious niece of President Buchanan, she participated in the naval expedition to Paraguay, and during the Civil War was often under fire. Again, during the war with Spain, the Revenue Cutter Service achieved an enviable and heroic record. The proper patrol of our long coast line requires a large number of vessels, and the Revenue Cutter Service at the present time has a complement of thirty-seven vessels, all splendidly adapted to the work in hand. During the last sixty years steamers have slowly but steadily replaced the top-sail schooners of the old days, and the vessels now employed by the Revenue Cutter Service are, with one or two exceptions, small, compact, well-built steamers, which, save for the guns they carry, might easily be mistaken for swift steam yachts. In size they range from 130 to 500 tons burden. The majority of them have been built under the direct supervision of officers of the service and are perfectly adapted to the varying wants of the several stations. Nearly all of them are armed with from two to four breech-loading rifled cannon and carry small arms for the use of their crews. Most of the vessels bear the names of former secretaries and assistant secretaries of the Treasury, but the Andrew Johnson, the William H. Seward and U. S. Grant are also among the names to be found on the list. The U. S. Grant, which does duty at Port Townsend, is a bark-rigged steam propeller, and a model of its size and type. Strange to say, it is the only ship of the United States that bears the name of the greatest captain of his age. The vessels of the Revenue Cutter Service are always ready for instant duty in the most distant quarters. When, in 1867, Alaska became a part of the United States, within a week after the ratification of the treaty, the revenue cutter Lincoln was steaming northward, and was the first to obtain accurate information regarding the geography, resources and climate of our new possession. Three or more revenue cutters now cruise every year in Alaskan waters, guarding the seal fisheries and often giving much needed relief to the whaling fleet that yearly sails from San Francisco for a cruise in the waters above the Behring Sea.
