Yet in another sense he did not consider those days lost. He gained, he used to feel afterwards, a knowledge of the world, a knowledge of men, a knowledge of affairs. This contact with realities took from his somewhat dreamy and reflective temperament its unpractical quality. If he chose afterwards to leave what is commonly called the world, it was a deliberate choice, founded on a thorough knowledge of its conditions, and not upon a timid and awkward ignorance. He did not leave the world because it frightened or bewildered him, but because he did not find in it the things of which he was in search. Neither, on the other hand, did he quit the life of affairs like a weakling or an inefficient person who had failed in it, and had persuaded himself that incompetence was unworldliness. Hugh became a remarkably efficient official, alert, sensible, practical, and prudent. He was marked out for promotion. He was looked upon as a man who got on well with inferiors and superiors alike, who could be trusted to do a complicated piece of business well, who was worth consulting. Moreover he acquired a very serviceable and lucid style, a power of clear statement, which afterwards stood him in good stead. His official work gave him the power of seeing the point, it gave him an economy of words, an effective briskness and solidity of presentment; at the same time his literary work prevented him from degenerating into a mere precis-writer. It is very difficult to say which of the days of a man's life are wasted and which are fruitful. It is not necessarily the days in which a man gives himself up to his chosen work in which he makes most progress. Sometimes a long inarticulate period, when there seems to a man to be a dearth of ideas, a mental drought, acts as a sort of incubation in which a thought is slowly conceived and perfected. Sometimes a long period of repression stores force at high pressure. The lean years are often the prelude, even the cause, of the years of fatness, when the exhausted and overteemed earth has lain fallow and still, storing its vital juices. Sometimes, too, a disagreeable duty, undertaken in heaviness and faithfully fulfilled, rewards one by an increase of mental strength and agility. A painful experience which seems to drown a man's whole nature in depression and sadness, to cloud hope and eagerness alike, can be seen in retrospect to have been a period fertile in patience and courage.
