I was in a rage; my blood boiled; at last my invention came to my aid, and, without considering the consequences, I determined how to act.

As it was an hour and a half before school would commence, I hastened home, and, having spent all my money, begged aunt Milly to give me some; she gave me a shilling, and with that I bought as much gunpowder as I could procure, more than a quarter of a pound.

I then returned to the school, looked into the school-room, and found it empty; I quickly raised up the claret case, under which the fireworks had been placed, put the powder under it, leaving only sufficient for a very small train, which would not be perceived in the green baize covering; having so done, I left the school-room immediately, and rejoined my companions. I had a piece of touch-wood, as all the boys had, to let off their fireworks with, and this I lighted and left in a corner until the bell should summons us into school.

Oh! how my heart beat when I heard the sound, so full was I of anxiety lest my project should fail.

Once more we were all assembled. Mr O’Gallagher surveying, with the smile of a demon, the unhappy and disappointed faces of the boys, was again perched upon his throne, the rod on one side, the ferrule on the other, and the ruler, that dreaded truncheon of command, clenched in his broad fist.

I had the touchwood lighted and concealed in my hand; gradually I moved downwards, until at last, unperceived by Mr O’Gallagher, I was behind him, and close to my train of gunpowder. I gave one look to ascertain if he had observed me; his eye was roving over the school for some delinquent to throw his ruler at; fearful that he might turn round to me, I no longer hesitated, and the touchwood was applied to the train.

Ignorant as I was of the force of gunpowder, it was with astonishment, mingled with horror, that I beheld, in a second, the claret case rise up as if it had wings, and Mr O’Gallagher thrown up to the ceiling enveloped in a cloud of smoke, the crackers and squibs fizzing and banging, while the boys in the school uttered a yell of consternation and fear as they rushed from from the explosion, and afterwards, tumbling over one another, made their escape from the school-room.

The windows had all been blown out with a terrible crash, and the whole school-room was now covered by the smoke. There I stood in silent dismay at the mischief which I had done. The squibs and crackers had not, however, all finished popping, before I heard the howling of Mr O’Gallagher, who had fallen down upon the centre school-room table.

I was still in the school-room, half-suffocated, yet not moving away from where I stood, when the neighbours, who had been alarmed by the explosion and the cries of the boys, rushed in, and perceiving only me and Mr O’Gallagher, who still howled, they caught hold of us both, and bore us out in their arms. It was high time, for the school-room was now on fire, and in a few minutes more the flames burst out of the windows, while volumes of smoke forced through the door and soon afterwards the roof.

The engines were sent for, but before they could arrive, or water be procured, the whole tenement was so enveloped in flames that it could not be saved. In an hour, the locale of our misery was reduced to ashes. They had put me on my legs as soon as we got clear of the school-room, to ascertain whether I was hurt, and finding that I was not, they left me.
