The Dutchmen were exceedingly ingenious in the invention of tricks and traps. One of these was to move a waggon with sixteen fat oxen in charge of but two men into the open Vlei below Tarantaal Ridge, and there to leave it, apparently unguarded, for two hours. They thought that this bait would lure forth the cattle-guard, but they were disappointed, for the authorities were too acute to allow them to get "a bite." They knew that in rear of the Vlei was a deep sand-drift, behind which a large body of men might be comfortably concealed, and consequently left waggon and cattle severely alone. After this began the bombardment by a new Boer gun--a diabolical instrument, whose perfections were hymned by an artillery expert, who declared it to be one of the most perfect pieces of ordnance ever made! A correspondent in the _Daily Telegraph_ described the terrifying effect produced on the nerves of the sick and the weakly. He went on: "The shock caused by the firing of this gun was distinctly perceptible five feet under ground at a distance of five miles, and the miniature earthquake thus created was clearly registered by the new seismograph at Kenilworth, the pendulum of which remained perfectly stationary during the firing of the smaller guns, or the passage of the most heavily laden trains or vehicles at very close quarters." The 9th of February was a terrible day. There was crashing and booming from morning till night, and no one dared venture abroad. One inhabitant had his child killed under his very eyes and his wife mortally stricken down. Towards sundown a shell struck the Grand Hotel, killing Mr. Labram, the De Beers chief engineer, whose valuable brains had been the salvation of the place. He had constructed armoured engines, armoured trains, and had completed his ingenious labours by constructing the huge 4.1-inch gun, with carriage and shells complete--a triumph of science considering the conditions under which the achievement was attempted. Now he was gone, and Kimberley was vastly the poorer.
