“Who’s going to nick the steel?” I said.

“Well,” said Bob coolly, “as I’ve done nearly all the rest of the work you may as well do that.”

I felt a moment’s hesitation, nothing more, and taking the flint, steel, and tinder-box, with a brimstone match, I went down on my knees beside the stone, where the piece of rag lay out ready, and after a great deal of nicking I made one of the sparks I struck fall into the tinder-box, and, after the customary amount of blowing, produced enough glow to ignite the tip of the brimstone-dipped match, which by careful shading fluttered and burned with a blue flame nearly invisible in the noontide light.

It was an extremely risky proceeding, for we had dropped some of the powder in among the short dry moss and stones, and then, too, the rag was drying fast, and it was quite within the range of possibilities that when I lit one end it might communicate too rapidly with the powder in the canister, and the explosion would take place before I could get out of the way.

But Bob Chowne and Bigley were standing only a couple of yards behind me, ready to dodge behind some of the great rocks on the comb of the ridge, and I believe that in those days I possessed so much of the Spartan fortitude which pervaded our school, that I would sooner have been blown up than show fear. So I sheltered my match, bending lower and lower, till I could bring it to a level with the powder-smeared rag, which caught at once, and began to sparkle and scintillate, sending up a thin blue flame at the same time.

That was enough, and throwing the match away, I began to back towards the lookers-on, but hearing a scuffling noise among the stones, I looked round to see that they were both running.

“Come on!” shouted Bob. “Look sharp, Sep!”

As they had begun to run it seemed to be no shame for me to do the same, so I darted after them, and found them just on the other side of the ridge, lying down behind some of the great rocks.

“That’s right,” cried Bob. “Creep close; nothing can hurt us here. Are you sure you left the thing burning?”

“Quite,” I said. “It must be off directly.”
