Yet it was a beautiful sight to see how bravely and manfully this young boy set himself to re-establish the reputation he had destroyed, and since he could not "build upon the _foundations_ of yesterday," to build upon its _ruins_; to see with what touching humility he accepted undeserved scorn, and with what touching gratitude he hailed the scantiest kindness; to see how he bore up unflinchingly under every difficulty, accepted his hard position among unsympathising schoolfellows, and made the most of it, without anger and without complaint. He could see in after years that those days were to him a time of unmitigated blessing. They taught him lessons of manliness, of endurance, of humility. The necessity of repairing an error and recovering a failure became to him a more powerful stimulus than the hope of avoiding it altogether. The hour of punishment, which was bitter as absinthe to his taste, became sweet as honey in his memory. Above all, these days taught him, in a manner never to be forgotten, the invaluable lesson that the sense of having done an ill deed is the very heaviest calamity that an ill deed ensures, and that in life there is no single secret of happiness comparable to the certain blessing brought with it by a conscience void of all offence. Perhaps the strain would have been too great for his youthful spirits, and might have left on his character an impress of permanent melancholy, derived from thus perpetually being reminded that he had gone wrong, but for a school sermon which Mr Paton preached about this time, and which Walter felt was meant in part for him. It was on the danger and unwisdom of brooding continually on what is over; and it was preached upon the text, "I will restore to you the years which the locust hath eaten, the canker-worm, the caterpillar, and the palmerworm, my great army." "The past is past," said the preacher; "its sins and sorrows are irrevocably over; why dwell upon it now? Do not waste the present, with all its opportunities, in a hopeless and helpless retrospect. The worst of us need not despair, much less those who may have been betrayed into sudden error by some moment of unguarded passion. There lies the future before you; onwards then, and forwards! it is yet an innocent, it may be a happy, future. Take it with prayerful thankfulness, and fling the withered part aside. Thus, although thus only, can you recover your neglected opportunities. Do this in hope and meekness, and God will make up to you for the lost past; He Who inhabiteth eternity will stretch forth out of His eternity a forgiving hand, and touch into green leaf again the years which the locust hath eaten." How eagerly Walter Evson drank in those words! That day at least he felt that man doth not live by bread alone, but by every word that proceedeth out of the mouth of God.
