Still, I could not collect my thoughts sufficiently to bring them to bear, in a practical way, on the central idea around which my fiction was to take body and shape. The sudden strain on my imagination had been too severe; a kind of numbness pervaded my whole being, and the moments, every one of which was precious as a grain of gold, were slipping idly away. The feeling that all the power to achieve what you desire lies there torpid within you, but too sullen to be either coaxed or bullied into action, laughing sluggishly at the most violent effort of the will to move it, is, perhaps, one of the most exasperating that a man can experience. It is like one in a nightmare, who sees impending over him a nameless terror that it only needs a wag of a little tongue to divert, and yet the little tongue cleaves with such monstrous persistency to the roof of the parched mouth that not all the leverage of Archimedes himself could move it from its place. That fine power of man’s intellect, that clear perception and keen precision which can search the memory, and at a glance find the clew that it is seeking; that can throw out those far-reaching fibres over the garden of knowledge, gathering in from all sides the necessary stores, was as far away from me as from a madman’s dream. I could fasten upon nothing; my brain was in disorder, while the moments were lengthening into hours, and the hours slipping silently away. In despair I tried a cigar--a favorite refuge of mine in difficulties; and soon light clouds, pervaded with a subtle aroma, were added to those thinner clouds of undefined and indefinable images that floated around me, volatile, shadowy, intangible; mysterious, nebulous. Mr. Culpepper’s “materials” had quite evaporated, and I began to think dreamily of old days, of anything, everything, save what was to the point. I remember how poor old Wetherhead, of all people in the world--“Leatherhead” we used facetiously to style him at college--came up before me, and I laughed over the fun we had with him. What a plodder he was! When preparing for his degree, he took ferociously to wet towels. He had the firmest faith in wet towels. He had tried them for the matriculation, and found them “capital,” he assured us. “Try a towel, Leathers,” we would say to him whenever we saw him in difficulties. Poor fellow! He was naturally dull and heavy, dense and persistent as a clod. It would take digging and hoeing and trenching to plant anything in that too solid brain; and yet he was the most hopeful fellow alive. He was possessed with the very passion of study, without a streak of brightness or imagination to soften and loosen the hopeless mass of clay whereof his mind seemed composed; and so he depended on wet towels to moisten it. He almost wore his head out while preparing for the matriculation examen. But by slow and constant effort he succeeded in forcing a sufficient quantity of knowledge into his pores, and retaining it there, to enable him to pass
