But Rawbon was not able to see much when, a little later, he had a chance to use the periscope. For one thing the short winter day was fading and the light was already poor; for another any attempt to keep the periscope above the parapet for more than a few seconds brought a series of bullets hissing and zipping over, and periscope glasses in those days were too precious to risk for mere curiosity's sake. "We'll just have a look at the Frying Pan," said Courtenay, "and then you'll have seen about the lot. We hold a bit of the trench running out beyond the Pan and the Germs are holding the same trench a little further along. We've both got the trench plugged up with sandbag barricades." They floundered along the twisting trench till it turned sharply to the right and ran out into the shallow hollow of the Frying Pan. It was swimming in greasy mud, and across the far side from where they stood Rawbon could see a breastwork of sandbags. "We call this entrance trench the Handle, and the trench that runs out from behind that barricade the Leak. There's always more or less bombing going on in the Leak, and I don't know if it's very wise of you to go up there. We call this the Frying Pan because--well, 'into the fire,' you know. Will you chance it?" "Why, sure; if you don't mind, Loo-tenant," said Rawbon, "I might as well see--" He was interrupted by a sudden crash and roar, running bursts of flaring light, hoarse yells and shouts, and a few rifle shots from somewhere beyond the barricade across the Leak. The work of the next minute was too fast and furious for Rawbon to follow or understand. The uproar beyond the barricade swelled and clamored, and the earth shook to the roar of bursting bombs. In the Frying Pan there was a sudden vision of confused figures, dimly seen through the swirling smoke, swaying and struggling, threshing and splashing in the liquid mud. He was just conscious of Courtenay shouting something about "Get back," of his being thrust violently back into the wide trench, of two or three figures crowding in after him, cursing and staggering and shooting back into the Frying Pan, of Courtenay's voice shouting again to "Stand clear," of a knot of men scrambling and heaving at something, and then of a deafening "Rat-tat-tat-tat," and the streaming flashes of a machine-gun. It stopped firing after a minute, and Rawbon, flattened back against a corner of the trench wall, heard an explanation given by a gasping private to Courtenay and another mud-bedaubed officer who appeared mysteriously from somewhere. "Flung a shower o' bombs an' rushed us, sir," said the private. "They was over a-top o' us 'fore you could say 'knife.' Only two or three o' us that wasn't downed and was able to get back out o' the Leak an' across the Pan to here." "We stopped them with the maxim," said Courtenay, "but I suppose they'll rush again in a minute."
