When my friendly companion found I could not understand him, he looked serious for a minute or two, then shortened his brilliant yellow toga, as though he had arrived at some resolve, and knelt down directly in front of me. He next took my face between his hands, and putting his nose within an inch of mine, stared into my eyes with all his might. At first I was inclined to laugh, but before long the most curious sensations took hold of me. They commenced with a thrill which passed all up my body, and next all feeling save the consciousness of the loud beating of my heart ceased. Then it seemed that boy's eyes were inside my head and not outside, while along with them an intangible something pervaded my brain. The sensation at first was like the application of ether to the skin--a cool, numbing emotion. It was followed by a curious tingling feeling, as some dormant cells in my mind answered to the thought-transfer, and were filled and fertilised! My other brain-cells most distinctly felt the vitalising of their companions, and for about a minute I experienced extreme nausea and a headache such as comes from over-study, though both passed swiftly off. I presume that in the future we shall all obtain knowledge in this way. The Professors of a later day will perhaps keep shops for the sale of miscellaneous information, and we shall drop in and be inflated with learning just as the bicyclist gets his tire pumped up, or the motorist is recharged with electricity at so much per unit. Examinations will then become matters of capacity in the real meaning of that word, and we shall be tempted to invest our pocket-money by advertisements of "A cheap line in Astrology," "Try our double-strength, two-minute course of Classics," "This is remnant day for Trigonometry and Metaphysics," and so on. My friend did not get as far as that. With him the process did not take more than a minute, but it was startling in its results, and reduced me to an extraordinary state of hypnotic receptibility. When it was over my instructor tapped with a finger on my lips, uttering aloud as he did so the words-- "Know none; know some; know little; know morel" again and again; and the strangest part of it is that as he spoke I did know at first a little, then more, and still more, by swift accumulation, of his speech and meaning. In fact, when presently he suddenly laid a hand over my eyes and then let go of my head with a pleasantly put question as to how I felt, I had no difficulty whatever in answering him in his own tongue, and rose from the ground as one gets from a hair-dresser's chair, with a vague idea of looking round for my hat and offering him his fee. "My word, sir!" I said, in lisping Martian, as I pulled down my cuffs and put my cravat straight, "that was a quick process. I once heard of a man who learnt a language in the moments he gave each day to having his boots blacked; but this beats all. I trust I was a docile pupil?"
