Balked and angry, as well as nonplussed, Governor Clinton insisted:
"Our laws require that all travellers in this government of New York shall swear allegiance to the King of England and have a license from the Governor."
Governor Clinton's name would certainly not adorn a license for these men. Whether or not the youth saw the trap, he was as frank as his interrogator:
"I never before heard of such a law in any country or kingdom in the world," replied Zeisberger.
"Will you not take the oath?" roared Governor Clinton, amazed.
"I will not," said the prisoner, and he was straightway cast into a prison, where he and his companion lay for six weeks, until freed by an ordinance passed by Parliament exempting the missionaries of the Moravian Church from taking oath to the British crown.
Back into the Iroquois land journeyed the liberated prisoner, and for ten doubtful years, until 1755, Zeisberger was engaged in learning the languages of the various tribes of the Six Nations, and in active missionary service. His success was very great. Perhaps in all the history of these famous Indians there was no other man, with the exception of Sir William Johnson, whom they trusted as much as they trusted David Zeisberger. Cheated on the one hand by the Dutch of New York, and robbed on the other by agents of the French and the English, the Iroquois became suspicious of all men; and it is vastly more than a friendly compliment to record that in his mission-house at Onondaga they placed the entire archives of their nation, comprising the most valuable collection of treaties and letters from colonial governors ever made by an Indian nation on this continent. But war now drove the missionary away, as throughout his life war was ever to dash his fondest dreams and ever to drive him back.
At the close of the Old French War, the missionaries of the Moravian Church were out again upon the Indian trails that led to the North and West. The first to start was Zeisberger, now in the prime of life, forty-two years old. But he did not turn northward. A call that he could not ignore had come to him from the friends of his boyhood days, the Delawares, who lived now in Western Pennsylvania. With a single companion he pushed outward to them. Taking up his residence in what is now Bradford County, Pennsylvania, he soon began to repeat the successes he had achieved in the Iroquois land, many being converted, and the whole nation learning to love and trust the earnest preacher. Then came Pontiac's terrible rebellion. Compelled to hurry back to the settlements again, Zeisberger awaited the end of that bloody storm, which swept away every fort in the West save only Fort Pitt and Fort Detroit.
At last the way was again open, and Zeisberger soon faced the wilderness. The Church fathers now came to the conclusion that it was best to extend missionary labor farther than ever before. The entire West had been saved to England, and the future was bright. It was Zeisberger to whom they looked, and not for a moment did the veteran flinch.
"Whither is the white man going?" asked an old Seneca chieftain of Zeisberger.
