How very demurely the two young gentlemen sat up that evening in the drawing-room, and pretended to be busily reading, though their thoughts were certainly not on their books; indeed, had Mr Nugent asked them what they were reading about, they would have been puzzled to give a satisfactory reply.

At last bed-time came, and the whole family retired to their rooms.

Mr Nugent made a practice of getting up early and never sat up late, except in a case of necessity, when he had some work of importance to finish. The boys, therefore, calculated that he would be asleep soon after eleven. The house was a large one, the elder boys had, therefore, rooms to themselves; but Julian and Digby slept in the same room on the first floor, and their window looked into the garden. All these circumstances were favourable to their design. Finding that there was a bolt on the door, they secured it. They did not undress, but, having put out their light, sat upon the foot of their beds whispering to each other till they thought everybody would be asleep. They then relighted their candle, and Julian, wetting some of their gunpowder, made a compound well known by the name of a Vesuvius; this he did up in a piece of paper. They then poured most of their powder into a pocket-handkerchief. It was a mercy that they did not blow themselves and indeed the house up. They stuffed their pockets full of paper, the rest of the powder, and some old handkerchiefs. Julian had not forgotten to provide a thick stick to serve as a rammer. The next thing they did was to fasten one end of their knotted rope to a bar across their window.

“Now all’s ready. Come along, Digby,” exclaimed Julian.

Digby descended first at the request of his companion, who wanted to ascertain whether the rope was properly secured before he trusted himself on it; finding it was safe, he followed. They looked about them as if they had been young thieves, to ascertain that they were not watched, and then crossing the lawn, they scrambled over a high wall, and ran on as hard as they could go towards the old fort.

It was close upon midnight when they reached the walls. They clambered in, and having selected a gun which pointed down directly on the harbour, they commenced the operation of loading.

“We must put in the handkerchief and all,” whispered Julian.

This was done, taking care to allow the powder to escape sufficiently at the upper side to communicate with the touch-hole. Then they rammed in a quantity of paper.

“Now let’s have some shot,” said Julian, “saw yesterday a pile of large gravel-stones, they will do famously.”

Some gravel-stones, or rather some large lumps of flint were found and rammed in, and the remainder of their paper was rammed in after them. Never before, probably, had the old gun been so fully charged. The nervous time was approaching. They filled the touch-hole with gunpowder, and on the top of it Julian placed his Vesuvius.
