Mr. Pardoe, the active police officer of York, was employed to ascertain to whom the shoemaker's pincers belonged, and they were owned by Mr. Lawn, at whose house Martin had lodged. Other circumstances formed a chain of evidence so complete and conclusive as to leave no doubt that Jonathan Martin was the incendiary, and hand-bills were issued on Thursday offering a reward for his apprehension. Pardoe had been despatched to Leeds in pursuit the previous day, with a warrant from Archdeacon Markham, which on his arrival was instantly backed by the Mayor of the borough. For the rest of the day and during the night Pardoe and the whole force of the police were employed in endeavouring to find a clue to the retreat of the incendiary. They were not successful; but on Thursday morning his wife was taken into custody while vending the "History of his Life." When discovered by the officers, she expressed her surprise at the charge against her husband; and after admitting that he left that town on Saturday morning, said that she understood, on his departure, he was going into the neighbourhood of Tadcaster; that she had not heard of him since; and that she had experienced great uneasiness at his long absence. She added that his place of concealment, or anything further connected with the affair, was totally unknown to her. She was kept in custody at Leeds, in her own house, in the charge of two constables, who obtained possession of all Martin's books and papers.

On Thursday morning information was received which caused an express to be sent off to the neighbourhood of Pontefract, where an active and diligent search was commenced. A clue was obtained, which led to the belief that the incendiary had passed through Pontefract on the road to Wakefield. The Mayor of Pontefract ordered the police of that town to afford every assistance to the gentlemen in pursuit, and he was traced to Polston toll-gate. From the information there obtained it was supposed he had taken the direction to Heath; and the pursuit was immediately followed up in that direction, and continued through most of Friday. It was reported in the evening about seven o'clock that Martin had been captured about five miles from Bedale, and would be brought into York by the Carlisle Express coach. The coach was half-an-hour beyond its time, and the streets were filled with crowds of anxious spectators, who waited in the expectation that the incendiary would arrive by it. Many persons went out of Micklegate Bar, and ran alongside of the coach till it stopped in Coney Street. It was then found that the report was an erroneous one, for Martin was not there; nor was it true that he had been captured.

On Saturday morning it was ascertained that the police had been on a wrong scent, as Martin had proceeded to the north instead of to the west; and about half-past nine o'clock that morning an express was received stating that he had been arrested the previous evening near Hexham. The following are the particulars of his flight and capture:

Martin left the Minster, as has been stated, a little after three o'clock in the morning. He proceeded to Easingwold and got a pint of ale; from thence to Thirsk, at which place he arrived at eleven o'clock; from Thirsk he went to Northallerton, where he arrived about three o'clock in the afternoon in a state of apparent fatigue. He remained till evening with a brother in-law who resided there, and expressed great anxiety to get on to Hexham to see a friend. At nine that evening he left Northallerton in a coal cart, in which he travelled all night till he arrived at Joft-hill pit, near West Auckland, on the Watling Street road. The next morning he proceeded to Alensford, on the Derwent, where he slept on the Tuesday evening. He left Alensford about eight o'clock on the Wednesday morning, and stopped at the Riding Mill, where he had a pint of ale; from thence he proceeded to Corbridge, where he arrived about twelve o'clock, and had half-a-pint of ale; and then went to Cadlaw Hill to his friend Mr. Kell, where he arrived about two the same afternoon, being the same place where he sought refuge when he escaped from the asylum at Gateshead. Martin remained there till eleven o'clock on Friday morning, and during his stay he expressed a great anxiety to see newspapers.

The handbills giving a description of Martin's person, and offering a reward for his apprehension, were circulated in all parts of the North; and one of them fell into the hands of Mr. Stainthorpe, a sheriff's officer, of Newcastle, who knew him. Mr. S., on Friday, the 6th, having to go to Corbridge, heard that Martin had returned home, but did not at that time know there was any charge against him. Returning to Hexham, where he kept a public-house, Mr. S. found the handbill lying on the table; and he immediately saddled his pony and set off to Mr. Kell's, where he felt satisfied he would find him. The house, called Cadlaw Hill, is situated between Stagshaw Bank and Hexham, on the north side of the Tyne. It is a house situated by itself, and had Martin not been well known in the neighbourhood, it might have afforded concealment for some time. On alighting he inquired of a young woman who was standing at the door if Jonathan Martin had got home. The family, it would seem, were not aware of the crime he had committed, as the bailiff was readily answered in the affirmative. On receiving this information he bolted in, and found Mr. Kell and Martin sitting together, the latter engaged in reading a hymn-book. They both rose on his entrance, and he, accosting Martin, asked, "Is not your name Jonathan Martin?" He immediately replied, "Yes, it is." On which Mr. Stainthorpe said, "You are my prisoner." Martin displayed very little emotion, nor did he even ask why he was made a prisoner. Mr. Kell was greatly surprised, and asked Mr. Stainthorpe what Martin was charged with. He replied he was not at liberty to tell him; but that he should require his assistance to convey the prisoner to Hexham, on reaching which place he would give him every information necessary. Mr. Kell readily agreed, and the prisoner as readily seemed disposed to take the road. The first question he asked Mr. Stainthorpe was, "Do you belong to York?" Mr. Stainthorpe replied in the negative, and cautioned him not to say anything that might criminate himself. On their coming in sight of Hexham, from which Cadlaw Hill is distant nearly four miles, Martin, pointing to Highside House, two miles from Hexham, said, "Yonder is the house in which I was born;" and seeing the church of Hexham, he exclaimed, "That is a fine old church. Did the Catholics build that too?" On the way Martin asked if any York papers came to Hexham. And also he said to Mr. Stainthorpe, "Am I advertised in the Newcastle papers?" On being told he was, and also that he was charged with burning York Cathedral, he readily said he had done it; and he added, "As soon as I knew I was advertised, I intended to tell everything." On reaching the House of Correction, Martin's bundle was opened, when it was found to contain part of the valuable crimson fringe, &c., which he said he had cut away from the pulpit, or some part of the Minster, a small Bible which he had brought away at the same time, and a piece or two of the painted glass of the Minster. An old razor was found in his pocket, with which he said he cut the crimson fringe, &c., and with which also he struck the fatal light by which he was able to fire the Minster. There were found also seven copies of his Life, but only one penny of money. He appeared up to the moment of his apprehension to have been profoundly ignorant of the extent of the injury he had occasioned; but on a gentleman telling him he had totally destroyed the Cathedral, his countenance brightened, and the news seemed to exhilarate him. He exclaimed, seemingly pleased, "Have I?" After he was lodged in the House of Correction an express was sent off to York with the intelligence.

It was whilst he was in the House of Correction at Hexham that Mr. Wilson (of whom mention has been made) visited him, in company with Mr. Stainthorpe. Mr. Wilson asked him whether his desire to see the newspapers at Cadlaw Hill arose from an anxiety for self-preservation. He replied, "None whatever;" but as he was ignorant what effects had been produced by the fires he had kindled, he was anxious to know; on which Mr. Stainthorpe said the damage was estimated at £100,000. He coolly said, "If it were not for the glory of God, if that could be promoted, £200,000 would not have been too much, and that in his opinion it would have been well if all the Minster had gone together, as the worship carried on in it was idolatrous and superstitious." He declared that he was quite happy and fully resigned to his situation, and "would give himself up into the hands of the Lord."

Such had been the demonstration of popular feeling shown by the persons collected at different times to wait the coaches coming in when Martin was expected, that the magistrates very prudently arranged that he should arrive in York early on Monday morning, and that the examination should take place immediately on his arrival. It was as near as possible half-past three o'clock when Mr. Newstead and Pardoe arrived with their prisoner in a post-chaise at the Session House in the Minster-yard. He was taken into the room occupied by Harrison, the keeper of Peter Prison, where he seated himself on a chair with his hands clasped, his feet elevated on the fender, and his eyes closed. Mr. Pardoe asked him if his feet were cold; to which he replied "Yes"; and this was the only word he spoke till the examination commenced. He was dressed in a blue coat and trousers, with a drab great-coat. He had by no means the appearance of a "stout man," as described in the bill; but the person where he lodged said he had fallen away very much in that short period.

It was half-past four o'clock when everything was arranged for examination. The magistrates took their seats on the bench, and Martin was placed at the bar; the warrant under which he was apprehended was read over to him, and the depositions of witnesses were also read.
