With just knowledge enough of Mr. Bremner's peculiar province to appreciate his views, I was much impressed by their broad and practical simplicity; and bethought me, as we conversed, that the character of the thinking, which, according to Addison, forms the staple of all writings of genius, and which he defines as "simple but not obvious," is a character which equally applies to _all_ good thinking, whatever its special department. Power rarely resides in ingenious complexities: it seems to eschew in every walk the elaborately attenuated and razor-edged mode of thinking,--the thinking akin to that of the old metaphysical poets,--and to select the broad and massive style. Hercules, in all the representations of him which I have yet seen, is the _broad_ Hercules. I was greatly struck by some of Mr. Bremner's views on deep-sea founding. He showed me how, by a series of simple, but certainly not obvious contrivances, which had a strong air of practicability about them, he could lay down his erection, course by course, inshore, in a floating caisson of peculiar construction, beginning a little beyond the low-ebb line, and warping out his work piecemeal, as it sank, till it had reached its proper place, in, if necessary, from ten to twelve fathoms water, where, on a bottom previously prepared for it by the diving-bell, he had means to make it take the ground exactly at the required line. The difficulty and vast expense of building altogether by the bell would be obviated, he said, by the contrivance, and a solidity given to the work otherwise impossible in the circumstances: the stones could be laid in his floating caisson with a care as deliberate as on the land. Some of the anecdotes which he communicated to me on this occasion, connected with his numerous achievements in weighing up foundered vessels, or in floating off wrecked or stranded ones, were of singular interest; and I regretted that they should not be recorded in an autobiographical memoir. Not a few of them were humorously told, and curiously illustrative of that general ignorance regarding the "strength of materials" in which the scientific world has been too strangely suffered to lie, in this the world's most mechanical age; so that what ought to be questions of strict calculation are subjected to the guessings of a mere common sense, far from adequate, in many cases, to their proper resolution. "I once raised a vessel," said Mr. Bremner,--"a large collier, chock-full of coal,--which an English projector had actually engaged to raise with huge bags of India rubber, inflated with air. But the bags, of course taxed far beyond their strength, collapsed or burst; and so, when I succeeded in bringing the vessel up, through the employment of more adequate means, I got not only ship and cargo, but also a great deal of good India rubber to boot." Only a few months after I enjoyed the pleasure of this interview with the Brindley of Scotland, he was called south, to the achievement of his greatest feat in at least one special department,--a feat generally recognized and appreciated as the most herculean of its kind ever performed,--the raising and warping off of the Great Britain steamer from her perilous bed in the sand of an exposed bay on the coast of Ireland. I was conscious of a feeling of sadness as, in parting with Mr. Bremner, I reflected, that a man so singularly gifted should have been suffered to reach a period of life very considerably advanced, in employments little suited to exert his extraordinary faculties, and which persons of the ordinary type could have performed as well. Napoleon,--himself possessed of great genius,--could have estimated more adequately than our British rulers the value of such a man. Had Mr. Bremner been born a Frenchman, he would not now be the mere agent of a steam company, in a third-rate seaport town.
