Obadiah Clayton, the Usher, began in June, 1800, to shew signs of insanity. The particular form that it took was the habit of producing pistols in School. He was put for a time in an asylum and a Mr. Tomlinson was to be written to as a successor, but as they did not hear from the Archbishop to whom they had applied for instructions, nothing was done. Later Clayton returned from the asylum but possibly for a time took no part in the School work. In 1802 the Governors went to the expense of 5_s._ 4_d._ in order to get advice on the propriety of complying with his request that he should attend a private pupil during school hours and should be allowed to take the globes from the School. His request was negatived. Two years later, matters reached a head, his conduct was not considered consistent and the Archbishop suggested that they should pay him the statutory minimum of £50 and hire an Assistant. The difficulty lay in the fact that he held a freehold and could only with great difficulty be made to resign. Meanwhile, Carr and Ingram were requested to report upon his conduct. Ingram declared that Clayton's conversation was of a wild and incoherent nature, but Carr was more minute. He reported that Clayton did not attend the School much for three weeks and that during that time he appeared to be in a deranged state of mind and made use of expressions such as that he had got a letter from his wife in heaven, or that the roads on which he walked were paved with fire. Although the immediate cause of his mental derangement was the death of his wife, he had never enjoyed good health. One of his testimonials from the Tutor of Magdalene College, Cambridge, had said that he had been compelled to leave Magdalene temporarily owing to ill health. He continued however to teach until 1805, when at his own suggestion he was allowed to absent himself for four years without giving up his license and he received £50 a year. This permission was characterized by the Archbishop as an act of humanity, but the legality of thus disposing of the Trust money was seriously questioned. A year later the Governors received a letter from him, saying that he had had many difficulties and had visited many parts of England but his "_dernier resort_" was at Bognor Barracks where he had enlisted as a private soldier and was anxious to be bought out. Some neighbouring clergy had interested themselves in his case and the Bishop of Chichester was willing to provide him with a curacy, provided that satisfactory answers came from the Governors of Giggleswick. Clayton begged them therefore to say that the cause of his leaving the School had been "ill-health." He was released from the Army but probably did not serve any curacy, for in May, 1808, he was acting as a Chaplain in the Royal Navy, after which nothing more is known of him though he continued to be paid his salary till 1810. His position as Usher was filled in that year by John Armstrong, who had been elected as a
