Stopping for the night at the ancient city of Tai-an-fu at the base of the mountain, we set out at six the next morning in chairs swung between poles borne by stalwart coolies. My curiosity was aroused when I found that they were Mohammedans and, as they cordially responded to my questionings, I found them very interesting. Centuries ago, their ancestors came to China as mercenaries, and taking Chinese wives settled in the country. But they have never intermarried since. They have adopted the dress and language of the Chinese, but otherwise they continue almost as distinct as the Jews in America. They instruct their children in the doctrines of Islam, though the Mohammedan rule that the Koran must not be translated has prevented all but a few literati from obtaining any knowledge of the book itself. They have done little proselyting, but natural increase, occasional reenforcements and the adoption of famine children have gradually swelled their ranks until they now number many millions in various parts of China. In some provinces they are very strong, particularly in Yun-nan and Kan-su where they are said to form a majority of the population. They are notorious for turbulence and are popularly known as ``Mohammedan thieves.'' It must be admitted that they not infrequently justify their reputation for robbery, murder and counterfeiting. More than once they have fomented bloody revolutions, one of them, the great Panthay rebellion of 1885-1874, costing the lives of no less than two million Moslems before it was suppressed. But those who bore me up the long slope of Tai-shan were as good-natured as they were muscular. There is no difficulty about ascending the mountain, for a stone-paved path about ten feet wide runs from base to summit. The maker of this road is unknown as the earliest records and monuments refer only to repairs. But he builded well and evidently with ``an unlimited command of naked human strength,'' for the blocks of stone are heavy and the masonry of the walls and bridges is still massive.
