The Anzac factory retorted with several brands, but the most favoured one was made out of the green fuse tin from the 18-pr. guns. These tins were stout, and of the size of a condensed milk tin. Two holes were punched in the bottom for a wire to go through, and three holes in the lid--two for the wire and a larger one for the fuse. The wire came from hawsers salved from the wreckage of the trawlers off the beach. Into the centre of the tin was placed a dry gun-cotton primer or half a stick of gelignite, the detonator and a five-seconds fuse was fitted, and the remaining space packed with unexploded Turkish cartridges with the bullets cut off to let the lid close, after which the whole was secured across the top by joining the two ends of the wires. So, from the cast-off tins and wires, captured ammunition, and the engineers' stores of explosives, these grenades were manufactured to repel the apparently rejuvenated "Sick Man of Europe." A time came when the gun-cotton and gelignite got scarce, and a powder explosive called ammonal had to be used. This presented a difficulty, as the stuff had to be packeted. But an active brain came to the rescue with a suggestion that cloth might be used for the packet. It so happened that about this time a large consignment of shirts had been opened up, all cut out and in the multitude of parts that go to make a shirt, but no two parts stitched together! This material was requisitioned, cut into squares, and the explosive packed like little bags of washing blue, with the detonator and fuse inside. Another time, tins ran out. The little mountain battery fuse tin was used as a stopgap, and then, luckily for Quinn's, another rascally manufacturer sent a shipment of mildewed tobacco to Anzac. The stuff was condemned, and before the day was done the empty tins lay in the bin of the bomb factory. Thus, though they did not intend it, did the careless London shirt inspector and the bad tobacco specialist help to keep the front line of the Anzac area. [Illustration: [_Lent by Capt. Boxer, N.Z.M.C._ CARRYING STORES UP WALKER'S RIDGE.] The Scarcity of Building Materials. It is questionable if any army in the field ever had too many sandbags. To keep earth walls standing at as steep a slope as possible is the object of all builders of trenches, for the steeper a wall the safer it is. "It is difficult to make war safe," says the soldier, who, being wise, does not attempt the impossible. But the same soldier takes few chances, and wherever he can build a wall or put on a roof that gives him real or fancied protection, nothing will stop him from collecting from somewhere the necessary material.
