Atlas clu Haut Yangtse de I-Tehang-fou a Pting-chan par Lo R.P.S. Chevalier, §.J. Shanghai: Lithographic de la Presse Orientale, 69 Rue clu Consular, 1899, This work appears most opportunely at 'a time when the navigation of the Upper Yangtze, through the five hundred miles of rapids and gorges from Ichang to Chungking, is about to be seriously undertaken by competent steamers, 'The trial made by Mr. Little in the spring of last year in a twin-sore' in launch de to the possibilities of the navigation
fleets of junks, tracked by men, is still more proved that whap is Pyseticable for large practicable for vessels propelled by steam power. A weak-powered boat had necessarily ta be assisted in the ascent by tracking at the worst rapids, but at, which many navigators declare; tw be the most difficult and dangerous part of the navigation, was performed without the slightest difficulty, and so the entice, of bringing the Treaty Port of Chungking into the general network of steam communication, utter being twenty years in abeyance, was definitely set at rest. Pare Chevalier has greatly facilitated the work of future navigators by the publication of these fine charts of the Upper River and lis earned the gratitude of all concerned in this most interesting undertaking. Blakiston's running survey, published in 1862, is an admirable and accurate piece of work, executed wuder great difficulties; but this as also the Admiralty chart from Hankow to K'ucifu are on too small a scale to afford much aid to the practical work of a river pilot. On the tier hand, Pere Chevalier, in his Atlas of the Upper Yangtze in thirty-eight Inge sheets, and on. the scale of two and a-half inches to the mile, 173,09) provides a chart upon which the chief dangers are carefully indicated, and, ut the same time, a convenient foundation for the complete and accus rate survey which subsequent navi; tors will gradually produce. For, seeing that the channel of the Upper River! is a rock-strewn bed from beginning to' end, the work of accurately tabulating these rocks will take years to complete, while as the high summer and the low winter levels in the Gorges vary to the extent -of one hundred and fifty feet in! height, a series of charts at these different levels would be required to delineate the river in all its stages:—though this is doubtless a counsel of perfection.
