As the Brethren had already been driven from Poland, the task which Israel now undertook appeared an act of folly. But George Israel knew better. For a hundred years the people of Poland had sympathised to some extent with the reforming movement in Bohemia. There Jerome of Prague had taught. There the teaching of Hus had spread. There the people hated the Church of Rome. There the nobles sent their sons to study under Luther at Wittenberg. There the works of Luther and Calvin had been printed and spread in secret. There, above all, the Queen herself had been privately taught the Protestant faith by her own father-confessor. And there, thought Israel, the Brethren in time would find a hearty welcome. And so, while still retaining the oversight of a few parishes in East Prussia, George Israel, by commission of the Council, set out to conduct a mission in Poland {1551.}. Alone and on horseback, by bad roads and swollen streams, he went on his dangerous journey; and on the fourth Sunday in Lent arrived at the town of Thorn, and rested for the day. Here occurred the famous incident on the ice which made his name remembered in Thorn for many a year to come. As he was walking on the frozen river to try whether the ice was strong enough to bear his horse, the ice broke up with a crash. George Israel was left on a solitary lump, and was swept whirling down the river; and then, as the ice blocks cracked and banged and splintered into thousands of fragments, he sprang like a deer from block to block, and sang with loud exulting voice: "Praise the Lord from the earth, ye dragons and all deeps; fire and hail, snow and vapour, stormy wind fulfilling his word." There was a great crowd on the bank. The people watched the thrilling sight with awe, and when at last he reached firm ground they welcomed him with shouts of joy. We marvel not that such a man was like the sword of Gideon in the conflict. He rode on to Posen, the capital of Great Poland, began holding secret meetings, and established the first evangelical church in the country. The Roman Catholic Bishop heard of his arrival, and put forty assassins on his track. But Israel was a man of many wiles as well as a man of God. He assumed disguises, and changed his clothes so as to baffle pursuit, appearing now as an officer, now as a coachman, now as a cook. He presented himself at the castle of the noble family of the Ostrorogs, was warmly welcomed by the Countess, and held a service in her rooms. The Count was absent, heard the news, and came in a state of fury. He seized a whip. "I will drag my wife out of this conventicle," he exclaimed; and burst into the room while the service was proceeding, his eyes flashing fire and the whip swinging in his hand. The preacher, Cerwenka, calmly went on preaching. "Sir," said George Israel, pointing to an empty seat "sit down there." The Count of Ostrorog meekly obeyed, listened quietly to the discourse, became
