In August we had two weeks' vacation. It was about this time that I became a member of the Rivermouth Centipedes, a secret society composed of twelve of the Temple Grammar School boys. This was an honor to which I had long aspired, but, being a new boy, I was not admitted to the fraternity until my character had fully developed itself. It was a very select society, the object of which I never fathomed, though I was an active member of the body during the remainder of my residence at Rivermouth, and at one time held the onerous position of F. C., First Centipede. Each of the elect wore a copper cent (some occult association being established between a cent apiece and a centipedes suspended by a string round his neck). The medals were worn next the skin, and it was while bathing one day at Grave Point, with Jack Harris and Fred Langdon, that I had my curiosity roused to the highest pitch by a sight of these singular emblems. As soon as I ascertained the existence of a boys' club, of course I was ready to die to join it. And eventually I was allowed to join. The initiation ceremony took place in Fred Langdon's barn, where I was submitted to a series of trials not calculated to soothe the nerves of a timorous boy. Before being led to the Grotto of Enchantment--such was the modest title given to the loft over my friend's wood-house--my hands were securely pinioned, and my eyes covered with a thick silk handkerchief. At the head of the stairs I was told in an unrecognizable, husky voice, that it was not yet too late to retreat if I felt myself physically too weak to undergo the necessary tortures. I replied that I was not too weak, in a tone which I intended to be resolute, but which, in spite of me, seemed to come from the pit of my stomach. “It is well!” said the husky voice. I did not feel so sure about that; but, having made up my mind to be a Centipede, a Centipede I was bound to be. Other boys had passed through the ordeal and lived, why should not I? A prolonged silence followed this preliminary examination and I was wondering what would come next, when a pistol fired off close by my ear deafened me for a moment. The unknown voice then directed me to take ten steps forward and stop at the word halt. I took ten steps, and halted. “Stricken mortal,” said a second husky voice, more husky, if possible, than the first, “if you had advanced another inch, you would have disappeared down an abyss three thousand feet deep!” I naturally shrunk back at this friendly piece of information. A prick from some two-pronged instrument, evidently a pitchfork, gently checked my retreat. I was then conducted to the brink of several other precipices, and ordered to step over many dangerous chasms, where the result would have been instant death if I had committed the least mistake. I have neglected to say that my movements were accompanied by dismal groans from different parts of the grotto.
