Closely allied with the subject of invasion are the German methods of "frightfulness" by means of their submarines and aircraft. Of the latter, it would seem, we are justified in speaking with absolute contempt. Three attempts at air raids on our shores have been made, and though, unhappily, some innocent lives were lost through the enemy's indiscriminate bomb-dropping, the military effect up to the day I pen these lines has been absolutely nil, except to assist us in bringing more recruits to the colours. Several of the vast, unwieldy Zeppelins, of which the Germans boasted so loudly, have been lost either through gunfire or in gales, while we have official authority for saying that our own air-service is so incomparably superior to that of the enemy that the German aviators, like the baby-killers of Scarborough, seek safety in retreat directly they are confronted by the British fliers. No doubt the German air-men have their value as scouts and observers, but it is abundantly clear that, as a striking unit, they are hopelessly outclassed. They have done nothing to compare with the daring raids on Friedrichshafen and Düsseldorf, to say nothing of the magnificent and devastating attack by the British and French air-men on Zeebrugge, Ostend, and Antwerp.

The submarine menace stands on another and very different footing, for the simple reason that luck, pure and simple, enters very largely into the operations of the underwater craft. It is quite conceivable that, favoured by fortune and with a conveniently hidden base of supplies—one of which, a petrol-base, I indicated to the authorities on March 15th—either afloat or ashore, submarines might do an enormous amount of damage on our trade routes.

A few dramatic successes may, of course, produce a scare and send insurance and freight rates soaring. Moreover, the submarine is exceedingly difficult to attack: it presents a very tiny mark to gunfire, and when it sights a hostile ship capable of attacking it, it can always seek safety by submerging. But, when all is said and done, the number of German submarines, given all the good fortune they could wish, is quite inadequate seriously to threaten the main body of either our commerce or our Navy.

We are told, and quite properly, nothing of the methods which the Admiralty are adopting to deal with German pirates. But it will not have escaped the public attention that the submarines have scored no great success against British warships since the Hawke was sunk in the Channel. I think we may fairly conclude, therefore, that our Admiralty have succeeded in devising new means of defence against the new means of attack. We know that at the time of writing two enemy submarines have been sunk by the Navy, and it seems fairly certain that another was rammed and destroyed in the Channel by the steamer Thordis. Whatever, therefore, may be our views on the general subject of the war, it seems clear that we can safely treat the submarine menace as the product of the super-heated Teutonic imagination.

We know of, and can guard against, the risks we run of any armed attack from Germany. But there is another peril which will face us when the war is over—a renewal of the commercial invasion which we have seen in progress on a gigantic scale for years past.

We know how the British market has, for years, been flooded with shoddy German imitations of British goods to the grave detriment of our home trade. We know, too, how the German worker, over here "to learn the language," has wormed himself into the confidence of the foolish English employer, and has abused that confidence by keeping his real principals—those in Germany—fully posted with every scrap of commercial information which might help them to capture British trade. We know, though we do not know the full story, that hundreds of "British" companies have been, in fact, owned, organised, and controlled solely by Germans. We know that for years German spies and agents, ostensibly engaged in business here, have plotted our downfall.

Are we going to permit, when the war is over, a repetition of all this?

I confess I look upon this matter with the gravest uneasiness. It is all very well to say that after the war Germans will be exceedingly unpopular in every civilised community. That fact is not likely to keep out the German, who is anything but thin-skinned. And, I regret to say, there are only too many British employers who are likely to succumb to the temptation to make use of cheap German labour, regardless of the fact that they will thus be actively helping their country's enemies.

Germans to-day are carrying on business in this country with a freedom which would startle the public, if it were known. I will mention two instances which have come to my knowledge lately. The first is the case of a company with an English name manufacturing certain electric fittings. Up to the time the war broke out, every detail of this company's business was regularly transmitted once a week to Germany: copies of every invoice, every bill, every letter, were sent over. Though the concern was registered as an "English" company, the proprietorship and control were purely and wholly German. That concern is carrying on business to-day, and in the city of London, protected, no doubt, by its British registration. And the manager is an Englishman who, before the war, explained very fully to my informant the entire system on which the business was conducted.

The second case is similar, with the exception that the manager is a German, at least in name and origin, who speaks perfect English, and is still, or was very recently, conducting the business. In this case, as in the first, every detail of the business was, before war broke out, regularly reported to the head office of the firm in Germany. I wonder whether English firms are being permitted to carry on business in Berlin to-day!
