The chief naval event was the daring British raid on the German submarine bases at Zeebrugge and Ostend; the channel at the first named port was blocked, and the harbor entrance at Ostend, by means of a second raid, was partially blocked, resulting in a serious hampering of submarine operations. The Italians penetrated Pola Harbor, May 14, with a small torpedo boat and sank a 20,000-ton Austrian dreadnought. SINN FEIN PLOT FRUSTRATED During the night of May 18 the British authorities in Ireland suddenly arrested at their homes about 500 of the leading Sinn Feiners on the charge of having treasonable communication with the German enemy. Among those arrested were the Sinn Fein members of Parliament, also the conspicuous Irish agitators and irreconcilables, both men and women. A proclamation was issued by the Lord Lieutenant declaring that a conspiracy with Germany had been discovered, calling upon all loyal Irishmen to assist in suppressing it, and urging voluntary enlistments. It was believed that this prompt action had prevented a contemplated uprising, which was being aided by German spies. Comparative calm followed the arrests. FOCH'S ARMY COMPRISES ALL RACES OF EARTH It seems certain that never in the world's history were so many different races, peoples, and tongues united under the command of a single man as are now gathered together in the army of Generalissimo Foch. If we divide the human races into White, Yellow, Red, and Black, all four are largely represented. Among the white races there are Frenchmen, Italians, Portuguese, English, Scottish, Welsh, Irish, Canadians, Australians, South Africans, (of both British and Dutch descent,) New Zealanders; in the American Army, probably every other European nation is represented, with additional contingents from those already named, so that every branch of the white race figures in the ethnological total. There are representatives of many Asiatic races, including not only the volunteers from the native States of India, but elements from the French colony in Cochin China, with Annam, Cambodia, Tonkin, Laos, and Kwang Chau Wan. England and France both contribute many African tribes, including Arabs from Algeria and Tunis, Senegalese, Saharans, and many of the South African races. The red races of North America are represented in the armies of both Canada and the United States, while the Maoris, Samoans, and other Polynesian races are likewise represented. And as, in the American Army, there are men of German, Austrian, and Hungarian descent, and, in all probability, contingents also of Bulgarian and Turkish blood, it may be said that Foch commands an army representing the whole human race, united in defense of the ideals of the Allies. The presence, among Foch's strategic reserves, of 250,000 Italian soldiers is peculiarly interesting, as no Italian force at all comparable to this in numbers seems ever to have operated on French soil, though French armies have
