The five boys, seeing the flash and being prepared for catastrophes, ducked below their desks, and were none of them seriously hurt. The window was blown out into the playground, and the blackboard on its easel was upset. The slate was smashed to atoms. Some plaster fell from the ceiling. No other damage was done to the school edifice or appliances, and the boys at first, seeing nothing of Plattner, fancied he was knocked down and lying out of their sight below the desks. They jumped out of their places to go to his assistance, and were amazed to find the space empty. Being still confused by the sudden violence of the report, they hurried to the open door, under the impression that he must have been hurt, and have rushed out of the room. But Carson, the foremost, nearly collided in the doorway with the principal, Mr. Lidgett. Mr. Lidgett is a corpulent, excitable man with one eye. The boys describe him as stumbling into the room mouthing some of those tempered expletives irritable schoolmasters accustom themselves to use--lest worse befall. "Wretched mumchancer!" he said. "Where's Mr. Plattner?" The boys are agreed on the very words. ("Wobbler," "snivelling puppy," and "mumchancer" are, it seems, among the ordinary small change of Mr. Lidgett's scholastic commerce.) Where's Mr. Plattner? That was a question that was to be repeated many times in the next few days. It really seemed as though that frantic hyperbole, "blown to atoms," had for once realised itself. There was not a visible particle of Plattner to be seen; not a drop of blood nor a stitch of clothing to be found. Apparently he had been blown clean out of existence and left not a wrack behind. Not so much as would cover a sixpenny piece, to quote a proverbial expression! The evidence of his absolute disappearance, as a consequence of that explosion, is indubitable.
