Having to deal with circumstances perpetually varying, and frequently presenting features entirely new, the profession to which he had devoted himself afforded almost the best possible opportunities for the development and application of this quality of mind. And, in a greater or less degree, every voyage he undertook as commander served to elicit this admirable characteristic. Those who understood him not, very naturally ascribed many of his novel proceedings to eccentricity, and these might be liable to run into this very usual extreme; but, for the most part, the apparent eccentricity was, in reality, a sound result of reflective, philosophical consideration. I might adduce some incidents, perhaps, in which the originality of conception was pushed into an extreme: yet I could recal, possibly, hundreds of others in which such conceptions resulted in proceedings at once admirable, in their fitness, and, as such, worthy of imitation. * * * * * 1. Take, for example, the process of _sallying_ the ice-bound ship for relieving her of any remediable pressure, and giving free action to the power of wind or “warps” for promoting her progress. And in this we have an adaptation of a previously unapprehended mean and provision, always at hand, possessing extraordinary capabilities as a mechanical force. It may not be uninteresting to elucidate this fact. Suppose a ship, navigating the Arctic seas, to be held firmly on the sides by the contact of two large sheets, or numerous compacted pieces, of ice. The ice just a-head may be less compact, or there may be a proximate channel, available for “boring” or sailing, if the existing pressure could be relieved so that the ship might be free to move. For the relief of this _lateral_ pressure, no mechanical force, except the action of the wind on the sails when coming somewhat in the direction of “the beam,” had heretofore been considered as available, or had been applied. But my Father’s device afforded a novel, as well as a powerfully available, agency. In what degree powerful is easily estimated. The ship, in the case referred to, we will suppose is tolerably flat-sided (like the Resolution), and floats, ordinarily, at the depth of the greatest width. Now the power yielded by sallying may be considered as corresponding with that obtained by a wedge acted on by a heavy weight; the _wedge_, in this case, being the portion of the ship’s side that becomes depressed, operating by virtue of the expansion of the ship’s _width_ when heeling, and the _force_ acting on the wedge being the weight transferred from an even distribution with an upright position of the ship, to an accumulation of weight on one side, inducing a heeling position. Let the extent of heeling be considered as a “streak” of nine inches, in which case, as the opposite side will be proportionally and equally raised, the width of the line of flotation will
