as larger vessels to pass. As most of the river work was of this character, the broadsides of the sloops were determinative, and those of the frigates would have been more so, could they have been brought to the scene; but they could not. Much labor was expended in the attempt to drag the _Colorado_, sister ship to the _Wabash_, across the bar of the Mississippi, but fruitlessly. For the reason named, the screw-frigates built in the fifties had little active share in the Civil War. Were they then, from a national stand-point, uselessly built? Not unless preparation for war is to be rejected, and reliance placed upon extemporized means. To this resort our people have always been inclined to trust unduly, owing to a false or partial reading of history; but to it they were excusably compelled by the extensive demands of the War of Secession, which could scarcely have been anticipated. At the time these frigates were built, they were, by their dimensions and the character of their armaments, much the most formidable ships of their class afloat, or as yet designed. Though correctly styled frigates--having but one covered deck of guns--they were open to the charge, brought against our frigates in 1812 by the British, of being ships-of-the-line in disguise; and being homogeneous in qualities, they would, in acting together, have presented a line of battle extorting very serious consideration from any probable foreign enemy. It was for such purpose they were built; and it was no reproach to their designers that, being intended to meet a probable contingency, they were too big for one which very few men thought likely. At that moment, when the portentous evolution of naval material which my time has witnessed was but just beginning, they were thoroughly up-to-date, abreast and rather ahead of the conclusions as yet reached by contemporary opinion. The best of compliments was paid them by the imitation of other navies; for, when the first one was finished, we sent her abroad on exhibition, much like a hen cackling over its last performance, with the result that we had not long to congratulate ourselves on the newest and best thing. It is this place in a long series of development which gives them their historical interest.
