designer and constructor of the Forth Bridge, the grandest and most original bridge in the world, received no regular engineering education." It was at Powick, too, that place of many inventions, that Herbert Spencer (aetat. 20) made the intimate acquaintance of an "intelligent, unconventional, amiable, and in various ways attractive" young lady, who "tended to diminish his brusquerie." Luckily or unluckily, the young lady was engaged; and Spencer remarks, "It was pretty clear that had it not been for the pre-engagement our intimacy would have grown into something serious. This would have been a misfortune, for she had little or nothing and my prospects were none of the brightest." Here the ancestral prudence crops out.

Glimpses of Evolution-Idea.—The year 1840-41 was "a nomadic period," of bridge-building at Bromsgroove and Defford, of "castle-building," too, for he dreamt of making a fortune by successful inventions, of testing engines, and other routine duties,—a life involving considerable wear and tear which began to tell on Spencer's eyes. During this period he renewed his youth by collecting fossils, and "making a collection is," as he afterwards said, "the proper commencement of any natural history study; since, in the first place, it conduces to a concrete knowledge which gives definiteness to the general ideas subsequently reached, and, further, it creates an indirect stimulus by giving gratification to that love of acquisition which exists in all." It was then that the purchase of Lyell's Principles of Geology led him, curiously enough, to adopt the supposition that organic forms have arisen, not by special creation, but by progressive modifications, physically caused and inherited. In spite of Lyell's chapter refuting Lamarck's views concerning the origin of species, it was with Lamarck that Spencer, at the age of twenty, sided. The idea of natural genesis was in harmony with the general idea of the order of Nature towards which Spencer had been growing. "My belief in it never afterwards wavered, much as I was, in after years, ridiculed for entertaining it."

"The incident illustrates the general truth that the acceptance of this or that particular belief, is in part a question of the type of mind. There are some minds to which the marvellous and the unaccountable strongly appeal, and which even resent any attempt to bring the genesis of them within comprehension. There are other minds which, partly by nature and partly by culture, have been led to dislike a quiescent acceptance of the unintelligible; and which push their explorations until causation has been carried to its confines. To this last order of minds mine, from the beginning, belonged."

Spencer's engagement with Capt. Moorson came to a natural termination, and an offer of a permanent post on the Birmingham and Gloucester railway was declined, one motive being a desire to prepare for the future by a course of mathematical study, another being to work at an idea his father had arrived at of an electro-magnetic engine. Thus his twenty-first birthday was spent at home in Derby, after an absence of three and a half years,—which had been on the whole "satisfactory, in so far as personal improvement and professional success were concerned."

A Resting Period.—But when he got home he found his study of a work on the Differential Calculus a weariness to the flesh. "To apply day after day merely with the general idea of acquiring information, or of increasing ability," was not in him, though he could work hard when the end in view was definite or large enough. Moreover an article in the Philosophical Magazine led to an immediate abandonment of the idea of an electro-magnetic engine. "Thus, within a month of my return to Derby, it became manifest that, in pursuit of a will-o'-the-wisp, I had left behind a place of vantage from which there might probably have been ascents to higher places."

As a consolation for what was at the time a disappointment, Herbert Spencer made a herbarium, which still retained in 1894 a specimen of Enchanter's Nightshade gathered in the grove skirting the river near Darley. In company with Edward Lott, with whom he formed a life-long friendship, he often spent the early summer morning, in rowing up the Derwent, which in those days was rural and not unpicturesque above Derby. As they rowed they sang popular songs, making the woods echo with their voices, and now and then arresting their "secular matins" for the purpose of gathering a plant. It is refreshing to read of Spencer having in his head a considerable stock of sentimental ballads.

It was during this fallow year that at the age of one-and-twenty he went with his father on a walking tour in the Isle of Wight, and first saw the sea. "The emotion produced in me was, I think, a mixture of joy and awe,—the awe resulting from the manifestation of size and power, and the joy, I suppose, from the sense of freedom given by limitless expanse." His father and he were good companions.

We read of various activities during this period,—of investigations, with inadequate mathematics, concerning the strength of girders, of experiments in electrotyping and the like, of botanical excursions, of some enthusiastic exercise in part-singing, drawing and modelling. In the early summer of 1842 Spencer paid a visit to his old haunts at Hinton. "The journey left its mark because, in the course of it, I found that practice in modelling had increased my perception of beauty in form. A good-looking girl, who was one of our fellow-passengers for a short interval, had remarkably fine eyes: and I had much quiet satisfaction in observing their forms." Our hero had not much sense of humour.

Beginning to write.—Of greater importance is the fact that Spencer began in 1842 to write letters to The Nonconformist on social problems, in which prominence was given to such conceptions as the universality of law and causation, progressive adaptation in organisms and in Man, and the tendency to equilibrium through self-adjustment. "Every day in every life there is a budding out of incidents severally capable of leading to large results; but the immense majority of them end as buds, only now and then does one grow into a branch, and very rarely does such a branch outgrow and overshadow all others." The visit to Hinton led to political conversations with Thomas Spencer, to a letter of introduction to the editor of The Nonconformist, to the letters on "The Proper Sphere of Government," to the Social Statics and eventually to the Synthetic Philosophy!

Spencer's next activity was an inquiry into his father's system of short-hand, which he found to be better than Pitman's. He passed to speculations on the methods to be followed in forming a universal language, and to shrewd criticisms of the decimal system of enumeration. In the autumn of 1842 he interested himself enthusiastically in "The Complete Suffrage Movement." For a youth of twenty-two he took a big plunge into politics. "It produced in me a high tide of mental energy"; the signature on a draft democratic bill "has a sweep and vigour exceeding that of any other signature I ever made, either before or since."

In the spring of 1843 Herbert Spencer went to London and tried very unsuccessfully to get editors to accept his wares. He made a pamphlet of his Nonconformist letters, but perhaps a hundred copies were sold! "The printer's bill was £10 2s. 6d., and the publisher's payment to me on the first year's sales was fourteen shillings and threepence!"

Experimenting with Life.—Spencer's half year in London came to little. As he says, he was too much "in the mood of Mr Micawber,—waiting for something to turn up, and waiting in vain." So he raised the siege and
