Throwing a tremendous column of water and debris high into the air and causing a shock which could be felt for miles, six tons of high xplosives were exploded on Thursday beneath two of the rocks in the Kunglington rapids, in the Upper Yangtze,

Preliminary investigating work was carried out in the winter of 1991-1999 in order to ascertain the practicability of bipating on the north side of Tachu, so as to give ships a clear run, whereas at pre- sent they have to set a devious

Most Dangerous Spot,

During the present winter, ns soon as the water fell low enough, work was started on these twó rocks, and it was decided to blast them Great difficulties wore en- countered in arranging means of Kcommunication, and the solution

was found in the building of a hut on the Tachu Rock (bearing the cheerful name, painted large on its side, of "Hopo Cottage,") and the establishment of a bridge of boats.

The precaution was taken, is view of the rapid and early rise in the river which had terminated the previous season's work, of building cofferdams of concrete on the rocks, to the height of ten feet, so that work could be con- tinued even if the river did rise a little.
