It is naturally not allowable to mention what the mechanical safeguards are, but the inexpert or indeed expert thief may certainly count on being guillotined or electrocutioned if he makes the attempt to emulate Colonel Blood’s adventure. It has been a source of some amusement to the warders to watch known burglars—for admission to view the Crown Jewels is open to all His Majesty’s subjects, not excluding burglars—with their faces flattened against the bars thinking, thinking, thinking, how possibly they could get hold of these priceless gems. One indeed, with a deep resigned sigh, was heard to mutter, “Gor’ blimy it ain’t to be done!” So we may hope for the best. Not only, however, are the Crown Jewels guarded by all the resources of science, but soldiers, yeomen warders, and policemen keep watch over them night and day. Just before the War, amongst other visitors was a German lady, who looked long at the Jewels and carefully examined the steel encasement in which they are exhibited. Then she went back to one of the yeomen on duty and remarked, “You may think those Jewels very wonderful and very wonderfully guarded, but do not be surprised if I say that they will soon belong to our Kaiser.” The yeoman was so taken aback that he did not know what to say, yet made perhaps a better reply than much forethought might have supplied. He said, “I don’t think so, madam. Pass along, please.” This old yeoman was in the Cameron Highlanders at the Relief of Lucknow. During the Great War the Germans in their first daylight raids made a special target of the Tower of London, clearly marked as it lay below on the banks of another clear landmark, the Thames. That their efforts to hit it were not more successful was a matter of bad luck for them and good for us, for we had then no anti-aircraft guns to drive them off. The first bomb just missed the Tower to the westward, and fell into the dry moat in the part used by the garrison as their drill ground. It penetrated six feet of gravel and rubble, deflecting at a slight angle as it went downward; then it ran nearly level for four more feet, and finally turned upwards at an angle and traversed another eighteen inches. Happily it failed to explode. When with much caution it was dug out tail first it was found to measure 4-1/2 ft. The top 22 in. formed an ordinary percussion shell, such as is fired by field artillery; the rest of the bomb consisted of a brass cylinder filled with a yellow powder. This powder, though perhaps intended for purely incendiary purposes, was doubtless intentionally also of a highly poisonous nature. So poisonous indeed was it that those who touched it were afflicted for months with a species of blood poisoning, which seriously affected their health and produced a painful and irritating skin disease. Indeed, one official was thus affected who had not to his knowledge even touched the infected portions of one of these bombs; he had merely stood close to
