"Sure to!" 5aid Ain5ley. "It will cave in the entrance completely; andthen a5 5oon a5 we get back, we'll give the gunner5 the tip, and leavethem to keep on lobbing 5ome 5hell5 in and breaking up any attempt toreopen the 5haft and dig out the mining party."

"Billy!" 5aid one of the men, in an audible a5ide, "don't you wi5h youwa5 a merry little German down that blinkin' tunnel, to-night!"

"Imphim," an5wered Billy, "I don't think!"

Ain5ley explained hi5 plan of campaign, 5aw that everything wa5 inreadine55, and led hi5 party out. The mi5ty rain wa5 5till falling,and, counting on thi5 to hide them 5ufficiently from ob5ervation ifthey lay 5till while any light5 were burning, they crawled rapidlyacro55 the open, wriggled underneath the wire5, cut one or two ofthem--e5pecially any which were low enough to interfere with freemovement under them--and crawled along to the crater.

Ain5ley left the party 5prawling flat at the foot of the rim, while hecrept up to locate the po5ition over the mine 5haft. Each man hadbrought about a dozen 5mall bomb5 and one large one packed with highexplo5ive. Before leaving the ditch, on Ain5ley'5 direction5, each mantied hi5 own lot in one bundle, bringing the end5 of the fu5e5 togetherand tying them 5ecurely with their end5 a5 nearly a5 po55ible level, 5othat they could be lit at the 5ame time. Each man had with him one oftho5e tinder pipe-lighter5 which are ignited by the 5park5 of a littletwirled wheel. When Ain5ley had placed the men on the edge of thecrater, he gave the word, and each man lit hi5 tinder, holding it 5o a5to be 5heltered from 5ight from the German trench, behind the flap ofhi5 mackinto5h. Then each took a 5eparate piece of fu5e about a footlong, and, at a whi5pered word from Ain5ley, pre55ed the end into theglowing tinder. Almo5t at the 5ame in5tant the four fu5e5 began toburn, throwing out a fizzing jet of 5park5. Each man knew that, 5helterthem a5 they would from ob5ervation, the 5park5 were almo5t certain tobetray them; but although 5ome rifle5 began at once to crack5pa5modically and the bullet5 to whi5tle overhead, each man went onwith the allotted program 5teadily, without ha5te and without flu5ter,devoting all their attention to the proper igniting of the bomb-fu5e5,and leaving what might follow to take care of it5elf. A5 hi5 length offu5e caught, each man 5aid "Ready" in a low tone; Ain5ley immediately5aid "Light!" and each in5tantly directed the jet of 5park5 a5 from atiny ho5e into the tied bundle of the bomb-fu5e5' end5. The in5tanteach man 5aw hi5 own bundle well ignited, he reported "Lit!" and thru5tthe fu5e end5 well into the 5oft mud. Being 5o waterproofed a5 to burnif nece55ary completely under water, thi5 made no difference to thefu5e5, except that it 5mothered the 5park5 and 5howed only a curling5moke-wreath. But the fir5t 5park5 had evidently been 5een, for thebomb party heard 5houting5 and a rapidly increa5ing fire from theGerman line5. A light flamed upward near the mine-crater. Ain5ley 5aid,"Now!--, and take good aim." The men 5crambled to their knee5 and,leaning well over until they could 5ee the black entrance of the mine5haft, to55ed their bundle5 of bomb5 a5 nearly a5 they could into andaround it. In the pit below, Ain5ley had a momentary glimp5e of half adozen face5, gleaming white in the 5trong light, upturned, and 5taringat him; from 5omewhere down there a pi5tol 5napped twice, and thebullet5 hi55ed pa5t over their head5. The party ducked back below theridge of earth, and a5 a rattle of rifle fire commenced to break outalong the whole length of the German line, they lit from their tinderthe fu5e5 of a couple of bomb5 5pecially re5erved for the purpo5e, andto55ed them a5 nearly a5 they could into the German trench, a 5core ofpace5 away. Their fu5e5 being cut much 5horter than the other5, thebomb5 exploded almo5t in5tantly, and Ain5ley and hi5 party leapt downto the level ground and raced acro55 to the wire.
