Early on the morning of his execution, Haggart joined earnestly in devotional exercise with his ministerial attendant. After the chaplain of the jail had prayed, one of the officers of justice appeared, and requested all strangers to retire, as he had something to communicate to the unhappy prisoner. Haggart immediately exclaimed, in a hurried tone, "Oh! I suppose it is the executioner." His firmness for a moment abandoned him, and he walked rapidly across the cell with his arms folded, and with deep despair strongly painted on his countenance. He speedily, however, regained his composure; and when the executioner did appear, at once allowed his arms to be bound. He was then removed to a hall in the lower part of the lock-up-house, where he was received by two of the clergymen of Edinburgh and the magistrates. After prayers the procession proceeded to the scaffold. The conduct of the unfortunate youth there was in the highest degree becoming. While the beneficial influence of religion was apparent in his whole demeanour, his natural firmness of character never for a moment forsook him. He kneeled down, and uttered an earnest prayer; and after addressing a few words of deep and anxious exhortation to the great multitude by whom he was surrounded, he met his fate with the same intrepidity which distinguished all the actions of his short, but guilty and eventful life, having just completed his twentieth year. He was executed at Edinburgh, July the 18th, 1821. Haggart, after his condemnation, wrote the history of his short and wicked life, which was subsequently published for the benefit of his father, who he requested might receive any profit arising from it, for the purpose of educating his younger brothers and sisters. The foregoing particulars are taken from this singular auto-biography, which evinced a strong, though uncultivated mind, which, if it had been directed to laudable pursuits, could not have failed to place the writer in an honorable station in society.
