But in spite of these distractions he fell into a dream as the 'bus rolled and tossed on its way Citywards, and still he strove to solve the enigma of his vigil of the night before, and as the shapes of trees and green lawns and houses passed before his eyes, and as he saw the procession moving on the pavement, and while the murmur of the streets sounded in his ears, all was to him strange and unaccustomed, as if he moved through the avenues of some city in a foreign land. It was, perhaps, on these mornings, as he rode to his mechanical work, that vague and floating fancies that must have long haunted his brain began to shape themselves, and to put on the form of definite conclusions, from which he could no longer escape, even if he had wished it. Darnell had received what is called a sound commercial education, and would therefore have found very great difficulty in putting into articulate speech any thought that was worth thinking; but he grew certain on these mornings that the 'common sense' which he had always heard exalted as man's supremest faculty was, in all probability, the smallest and least-considered item in the equipment of an ant of average intelligence. And with this, as an almost necessary corollary, came a firm belief that the whole fabric of life in which he moved was sunken, past all thinking, in the grossest absurdity; that he and all his friends and acquaintances and fellow-workers were interested in matters in which men were never meant to be interested, were pursuing aims which they were never meant to pursue, were, indeed, much like fair stones of an altar serving as a pigsty wall. Life, it seemed to him, was a great search for--he knew not what; and in the process of the ages one by one the true marks upon the ways had been shattered, or buried, or the meaning of the words had been slowly forgotten; one by one the signs had been turned awry, the true entrances had been thickly overgrown, the very way itself had been diverted from the heights to the depths, till at last the race of pilgrims had become hereditary stone-breakers and ditch-scourers on a track that led to destruction--if it led anywhere at all. Darnell's heart thrilled with a strange and trembling joy, with a sense that was all new, when it came to his mind that this great loss might not be a hopeless one, that perhaps the difficulties were by no means insuperable. It might be, he considered, that the stone-breaker had merely to throw down his hammer and set out, and the way would be plain before him; and a single step would free the delver in rubbish from the foul slime of the ditch.
