Gabriel was already among the turgid, prostrate forms. He had flung off his coat, rolled up his shirt-sleeves, and taken from his pocket the instrument of salvation. It was a small tube or trochar, with a lance passing down the inside; and Gabriel began to use it with a dexterity that would have graced a hospital surgeon. Passing his hand over the sheep's left flank, and selecting the proper point, he punctured the skin and rumen with the lance as it stood in the tube; then he suddenly withdrew the lance, retaining the tube in its place. A current of air rushed up the tube, forcible enough to have extinguished a candle held at the orifice.
