Although great efficiency and economy had now been attained, there was still an important defect to be remedied, namely, the impediment to speed and to evolution under sail presented by the dragging propeller; which was accomplished by the invention of the "trunk" or "well," into which the propeller can be raised at pleasure; and there is no longer anything to prevent the construction of a screw-frigate which shall be fit to accompany, under canvas only, a fleet of fast sailers, with the assurance that she may arrive at the point of destination in company with her consorts, having in reserve all her steam-power.
In considering the auxiliary screw-frigate under the views already offered, and in determining the canvas with which she should be supplied, it will be well to refer, as the best guide, to the fastest sail-ships, the class which presents the greatest similarity in form to that demanded in screw-ships.
To create a perfect screw-frigate, a ship with sail-power complete, and efficient for any service that may be required, the endeavor should be made by getting rid of every dispensable article of weight or bulk, and without reducing supplies below three months' provisions and six weeks' water to find space and displacement for an engine of sufficient force to drive her thirteen knots an hour, together with at least ten days' full consumption of fuel; and this, it is believed, might be successfully accomplished in ships of the dimensions of the Wabash, beginning with a judicious reduction of spare spars, spare sails, and spare gear, and by the addition of blowers to their present machinery: a subject which should immediately receive the earnest consideration of a commission of the most intelligent officers.
The screw-propeller, in fact, has assumed so important a part in all naval enterprise, that it may not be without interest to trace briefly its rise and progress to the consideration it now commands, and to review, in general terms, the various experiments by which the screw-frigate has been brought to its present high state of efficiency, excelling, for purposes of war, all other kinds of vessels.
When, at the outbreak of the rebellion, the navy-yard at Norfolk, Virginia, had to be abandoned to the enemy, the destruction at that time attempted by Commodore Paulding remained very incomplete. Among the vessels set on fire, the screw-frigate Merrimac, which had been scuttled, was burned only to the water's edge, leaving her hull and machinery entirely uninjured.
