At the beginning of each school term there were usually rough fellows who thought the quiet boy could be made the subject of practical jokes and petty annoyances without much danger of retaliation. Graham would usually remain patient up to a certain point, and then, in dismay and astonishment, the offender would suddenly find himself receiving a punishment which he seemed powerless to resist. Blows would fall like hail, or if the combatants closed in the struggle, the aggressor appeared to find in Graham's slight form sinew and fury only. It seemed as if the lad's spirit broke forth in such a flame of indignation that no one could withstand him. It was also remembered that while he was not noted for prowess on the playground, few could surpass him in the gymnasium, and that he took long solitary rambles. Such of his classmates, therefore, as were inclined to quarrel with him because of his unpopular ways soon learned that he kept up his muscle with the best of them, and that, when at last roused, his anger struck like lightning from a cloud. During the latter part of his college course he gradually formed a strong friendship for a young man of a different type, an ardent sunny-natured youth, who proved an antidote to his morbid tendencies. They went abroad together and studied for two years at a German university, and then Warren Hilland, Graham's friend, having inherited large wealth, returned to his home. Graham, left to himself, delved more and more deeply in certain phases of sceptical philosophy. It appeared to him that in the past men had believed almost everything, and that the heavier the drafts made on credulity the more largely had they been honored. The two friends had long since resolved that the actual and the proved should be the base from which they would advance into the unknown, and they discarded with equal indifference unsubstantiated theories of science and what they were pleased to term the illusions of faith. "From the verge of the known explore the unknown," was their motto, and it had been their hope to spend their lives in extending the outposts of accurate knowledge, in some one or two directions, a little beyond the points already reached. Since the scalpel and microscope revealed no soul in the human mechanism they regarded all theories and beliefs concerning a separate spiritual existence as mere assumption. They accepted the materialistic view. To them each generation was a link in an endless chain, and man himself wholly the product of an evolution which had no relations to a creative mind, for they had no belief in the existence of such a mind. They held that one had only to live wisely and well, and thus transmit the principle of life, not only unvitiated, but strengthened and enlarged. Sins against body and mind were sins against the race, and it was their creed that the stronger, fuller and more nearly complete they made their lives the richer and fuller would be the life that succeeded them.
