As to the second proposal, there will be no two opinions. Wireless is already forbidden, and there is no hardship in taking steps to see that the law is obeyed. With regard to the first suggestion, I am well aware that many people will think it, as indeed it is, extremely drastic. It would, of course, cause great inconvenience, not only to British subjects, but to the subjects of neutral Powers with whom we are on the best of terms. It would seriously interfere with business which we have every wish should continue, and I should never suggest it unless I were convinced of the urgent need. A correspondent who has just returned from Holland, where, says the _Evening News_, he saw British tradesmen doing business with German manufacturers, shows how easy it is for the Germans to send professional spies to England _via_ Flushing. A German permit will pass anyone over the Belgian frontier into Holland: a Belgian passport is not necessary, but such passports are issued by the local authorities. There is nothing to prevent a German commander getting a Belgian passport and issuing it to a German if it suits his purpose, while the present examination arrangements on the English side offer no obstacles to spies landing, especially from boats containing five or six hundred refugees. The remedy is to make the landing test far more stringent, and to use responsible Belgians in the work. One can readily understand that the average Englishman, even though he spoke French and Flemish, would not be able to detect a German, speaking both languages, as being anything but a genuine Belgian. Such a man, however, would be readily detected by a Belgian; however well he spoke the languages, some trick of accent or pronunciation would be sure to "give him away." Thus our Belgian friends could do much to prevent the German spy getting into the country. Assume that the spy is here; how are we to prevent him getting out? By closing the sea routes to all who could not produce to our Foreign Office absolutely satisfactory guarantees of their _bona fides_. The ordinary passport system is not sufficient; the Foreign Office should demand, and see that it gets not only a photograph, but a very clear explanation of the business of every person who seeks to travel from England to the Continent, backed by unimpeachable references from responsible British individuals, banks, or firms. In every single case of application for a passport it should be personal, and the most stringent enquiries should be made. I see no other means of putting an end to a danger which, whatever the official apologists may say, is still acute, and shows no signs of diminishing. Under the best of conditions some leakage may take place. But our business is to see, by every means we can adopt, that the leakage is reduced to the smallest possible proportions.
