"Taking the direction those shells are coming from, the distance from Poperinghe to that gun must be more than ten miles--if the gun is behind the German trenches. Your gunnery is pretty rotten, I know, but if you know of any two-inch gun that shoots ten miles, I'll be obliged if you'll give me some lessons." The gunner lit a cigarette. "Man, we know it's not one of ours, we know where they all are; we know it's a Hun." "Then, what in the name of fortune are ye standing here for talking like an ould woman with the indigestion? Away with you, and lead us to him, and don't go chivying after your bally major." Dick shouted for his revolver. "If there's a gun in that wood, bedad! we'll gun it." "My dear old flick," said the other, "don't get excited. The woods have been searched with a line of men--twice; and devil the sign of the gun. You don't suppose they've got a concrete mounting and the Prussian flag flying on a pole, do you? The detachment are probably dressed as Belgian peasants, and the gun is dismounted and hidden when it's not firing." But O'Rourke would have none of it. "Get off to your major, then, and have your mothers' meeting. Then come back to me, and I'll give you the gun. And borrow a penknife and cut your beard--you'll be after frightening the natives." That evening a couple of shots rang out from the same wood, two of the typical shots of a small gun. And then there was silence. A group of men standing by an estaminet on the road affirmed to having heard three faint shots afterwards like the crack of a sporting-gun or revolver; but in the general turmoil of an evening hate which was going on at the same time no one thought much about it. Half an hour later Dick O'Rourke returned, and there was a strange look in his eyes. His coat was torn, his collar and shirt were ripped open, and his right eye was gradually turning black. Of his doings he would vouchsafe no word. Only, as we sat down round the fire to dinner, the gunner subaltern of the morning passed again up the road. "Got the gun yet, Dick?" he chaffed. "I have that," answered O'Rourke, "also the detachment." The Land Crab paused. "Where are they?" "The gun is in a pond where you won't find it, and the detachment are dead--except one who escaped." "Yes, I don't think." The gunner laughed and passed on. "You needn't," answered Dick, "but that gun will never fire again." It never did. As I say, he would answer no questions, and even amongst the few people who had heard of the thing at all, it soon passed into the limbo of forgotten things. Other and weightier matters were afoot; the second battle of Ypres did not leave much time for vague conjecture. And so when, a few days ago, the question was once again recalled to my mind by no less a person than O'Rourke himself, I had to dig in the archives of memory for the remembrance of an incident of which I had well-nigh lost sight. * * * * *
