“Captain Kilgariff”—for Kilgariff had not yet announced his promotion even to his men—“one of the men is hurt by a fragment of the shell that burst over us half a minute ago. He seems badly wounded.” Instantly Kilgariff and Arthur Brent hurried to the pit where the wounded man lay, and Doctor Brent dressed his wound, which was serious. At his suggestion, Kilgariff ordered two of the men to carry the stricken one to the rear through the covered way, and deliver him to the surgeons of the nearest field-hospital. Just as the party started, a huge fifteen-inch mortar shell descended from a great height, struck the apex of the earth mound that covered the magazine, where ten minutes before the two friends had been sitting in converse, and there instantly exploded with great violence. Kilgariff hastened to inspect. He found the magazine intact, so far, at least, as its contents were concerned. There were more than a thousand pounds of Dupont rifle powder there, secured in wooden boxes called “monkeys,” and there were two thousand mortar shells there also, each weighing twenty-four pounds, each terribly destructive, potentially at least, and each loaded with a heavy charge of gunpowder. Fortunately the explosion of the gigantic shell had not ignited the magazine. Had it done so, neither a man nor a gun nor any trace of either would have remained in all that circle of mortar pits, to tell the tale of their occupancy. But practically all of the earth that had constituted the mound had been blown completely away, and some of the timbers that had supported it had been crushed till they had broken and fallen in. The man who had been in charge of the magazine was found crushed to a pulp by the falling of the timbers. When Kilgariff had fully explored, and discovered the extent of the disaster, he swore. Pointing to the mangled body of the man who had been caught in the ruin, he said to Arthur Brent:— “There was never a better man than Johnny Garrett. He had a wife and four children up in Fauquier County. The wife is a widow now, and the children are orphans, and Johnny Garrett is a shapeless mass of inert human flesh, all because of the incapacity of an engineer, damn him! I know the fellow—” But before continuing, Kilgariff turned to a sergeant and said:—
