'When the spring and activity of youth,' he wrote, 'is altogether unsanctified by anything pure and elevated in its desires, it becomes a spectacle that is as dizzying and almost more morally distressing than the shouts and gambols of a set of lunatics.'

One thing struck him as particularly strange: 'It is very startling,' he said, 'to see so much of sin combined with so little of sorrow.' The naughtiest boys positively seemed to enjoy themselves most. There were moments when he almost lost faith in his whole system of education, when he began to doubt whether some far more radical reforms than any he had attempted might not be necessary, before the multitude of children under his charge—shouting and gambolling, and yet plunged all the while deep in moral evil—could ever be transformed into a set of Christian gentlemen. But then he remembered his general principles, the conduct of Jehovah with the Chosen People, and the childhood of the human race. No, it was for him to make himself, as one of his pupils afterwards described him, in the words of Bacon, 'kin to God in spirit'; he would rule the school majestically from on high. He would deliver a series of sermons analysing 'the six vices' by which 'great schools were corrupted, and changed from the likeness of God's temple to that of a den of thieves'. He would exhort, he would denounce, he would sweep through the corridors, he would turn the pages of Facciolati's Lexicon more imposingly than ever; and the rest he would leave to the Praepostors in the Sixth Form.

Upon the boys in the Sixth Form, indeed, a strange burden would seem to have fallen. Dr. Arnold himself was very well aware of this. 'I cannot deny,' he told them in a sermon, 'that you have an anxious duty—a duty which some might suppose was too heavy for your years'; and every term he pointed out to them, in a short address, the responsibilities of their position, and impressed upon them 'the enormous influence' they possessed 'for good or for evil'. Nevertheless most youths of seventeen, in spite of the warnings of their elders, have a singular trick of carrying moral burdens lightly. The Doctor might preach and look grave; but young Brooke was ready enough to preside at a fight behind the Chapel, though he was in the Sixth, and knew that fighting was against the rules. At their best, it may be supposed that the Praepostors administered a kind of barbaric justice; but they were not always at their best, and the pages of "Tom Brown's Schooldays" show us what was no doubt the normal condition of affairs under Dr. Arnold, when the boys in the Sixth Form were weak or brutal, and the blackguard Flashman, in the intervals of swigging brandy-punch with his boon companions, amused himself by toasting fags before the fire.

But there was an exceptional kind of boy, upon whom the high-pitched exhortations of Dr. Arnold produced a very different effect. A minority of susceptible and serious youths fell completely under his sway, responded like wax to the pressure of his influence, and moulded their whole lives with passionate reverence upon the teaching of their adored master. Conspicuous among these was Arthur Clough. Having been sent to Rugby at the age of ten, he quickly entered into every phase of school life, though, we are told, 'a weakness in his ankles prevented him from taking a prominent part in the games of the place'. At the age of sixteen, he was in the Sixth Form, and not merely a Praepostor, but head of the School House. Never did Dr. Arnold have an apter pupil. This earnest adolescent, with the weak ankles and the solemn face, lived entirely with the highest ends in view. He thought of nothing but moral good, moral evil, moral influence, and moral responsibility. Some of his early letters have been preserved, and they reveal both the intensity with which he felt the importance of his own position, and the strange stress of spirit under which he laboured. 'I have been in one continued state of excitement for at least the last three years,' he wrote when he was not yet seventeen, 'and now comes the time of exhaustion.' But he did not allow himself to rest, and a few months later he was writing to a schoolfellow as follows:

'I verily believe my whole being is soaked through with the wishing and hoping and striving to do the school good, or rather to keep it up and hinder it from falling in this, I do think, very critical time, so that my cares and affections and conversations, thoughts, words, and deeds look to that in voluntarily. I am afraid you will be inclined to think this "cant" and I am conscious that even one's truest feelings, if very frequently put out in the light, do make a bad and disagreeable appearance; but this, however, is true, and even if I am carrying it too far, I do not think it has made me really forgetful of my personal friends, such as, in particular, Gell and Burbidge and Walrond, and yourself, my dear Simpkinson.'

Perhaps it was not surprising that a young man brought up in such an atmosphere, should have fallen a prey at Oxford, to the frenzies of religious controversy; that he should have been driven almost out of his wits by the ratiocinations of W. G. Ward; that he should have lost his faith; that he should have spent the rest of his existence lamenting that loss, both in prose and verse; and that he should have eventually succumbed, conscientiously doing up brown paper parcels for Florence Nightingale.

In the earlier years of his headmastership Dr. Arnold had to face a good deal of opposition. His advanced religious views were disliked, and there were many parents to whom his system of school government did not commend itself. But in time this hostility melted away. Succeeding generations of favourite pupils began to spread his fame through the Universities. At Oxford especially, men were profoundly impressed by the pious aims of the boys from Rugby. It was a new thing to see undergraduates going to Chapel more often than they were obliged, and visiting the good poor. Their reverent admiration for Dr. Arnold was no less remarkable. Whenever two of his old pupils met, they joined in his praises; and the sight of his picture had been known to call forth, from one who had not even reached the Sixth, exclamations of rapture lasting for ten minutes and filling with astonishment the young men from other schools who happened to be present.

He became a celebrity; he became at last a great man. Rugby prospered; its numbers rose higher than ever before; and, after thirteen years as headmaster, Dr. Arnold began to feel that his work there was accomplished, and that he might look forward either to other labours or, perhaps, to a dignified retirement. But it was not to be.

His father had died suddenly at the age of fifty-three from angina pectoris; and he himself was haunted by forebodings of an early death. To be snatched away without a warning, to come in a moment from the seductions of this World to the presence of Eternity—his most ordinary actions, the most casual remarks, served to keep him in remembrance of that dreadful possibility. When one of his little boys clapped his hands at the thought of the approaching holidays, the Doctor gently checked him, and repeated the story of his own early childhood; how his own father had made him read aloud a sermon on the text 'Boast not thyself of tomorrow"; and how, within the week, his father was dead. On the title page of his MS. volume of sermons, he was always careful to write the date of its commencement, leaving a blank for that of its completion. One of his children asked him the meaning of this. 'It is one of the most solemn things I do,' he replied, 'to write the beginning of that sentence, and think that I may perhaps not live to finish it.'

It was noticed that in the spring of 1842 such thoughts seemed to be even more frequently in his mind than usual. He was only in his forty-seventh year, but he dwelt darkly on the fragility of human existence. Towards the end of May, he began to keep a diary—a private memorandum of his intimate communings with the Almighty. Here, evening after evening, in the traditional language of religious devotion, he humbled himself before God, prayed for strength and purity, and threw himself upon the mercy of the Most High.
