It is not in the least degree likely that all the German arrangements and plans have been made for outside operations only, and that every internal device that could help to ruin us has been neglected; that is not at all the German way. It has already been officially admitted that there is reason for believing that the Germans have established petrol stores in these islands. Is there any reason why they should not equally have established depots of explosives for use in the same contingency? Our naval authorities say quite plainly that, with the present disposition of the Fleet, no invading force above the proportions of a raiding party intended to create panic could ever hope to reach these shores. To that, I think, the great majority of our people, supremely confident in our splendid Navy, cordially subscribe. But in war no chances can be taken, for the unexpected always happens, and though we may not discuss the measures that have been adopted, it is known that the War Office authorities have done everything possible to provide for even such a remote contingency. Can we say that the Home Office has done everything possible to cut the claws of the German plotters, when so many potential enemies are still allowed to be at large amongst us? And further, many enemy aliens are now being released, and returning to their employment in hotels. Mr. McKenna has quite justifiably claimed that the Confidential Department has broken up the organisation of spies that existed in England before the war. For that, I desire quite sincerely to give them every credit. The Home Secretary has admitted, however, the necessity of taking every possible step to deal with those who have come here since the war began. And in this connection a very serious position has been created by the swarms of unhappy refugees from Belgium who have been pouring into the country for several months past. Among these thousands, it is absolutely certain, there must be many clever German agents, possibly men who have long lived in Belgium, and speak French or Flemish without a trace of German accent. What steps are being taken to guard against this peril? It must be remembered that in the case of these unfortunate people there can be no question of passports, or papers of any kind. The great majority of them are quite glad enough to have escaped with their lives, without troubling about their papers, even had they wished to do so. There would not be the slightest difficulty in German agents slipping over amongst these thousands without any risk of detection, and we can be tolerably confident that many have done so.
