Then we descended again to the flats of the Bow. In spite of several fordings of the deep, swift river, the going here was the best since leaving Lake Louise, due princi pally to the fact that, with the valley floor sloping at a sharper declivity, more water had been drained out of the clinging, blue-gray glacial silt with which it was paved. THE SCOURGE OF GLACIAL SILT First and last, glacial silt was the most annoying obstacle we encountered on the whole journey. The main by-product of the grinding mills of the ice makes the muddiest mud, as well as the dustiest is~ ;i Our packers claimed that glacial silt had one use. It was a won derful abrasive-had no equal, in fact, when used as a paste on razor strops. Not hav ing shaved during the trip, I had no chance to test this single vir byLewis R.

We followed the winding ribbon of the Bow until mountain meadows, gay with flowers, gave place to the narrow and precipitous canyon which drains the lake above. Then we were forced to ascend to a series of sloping benches to the north for another miserable stage in bogs and fallen timber. Climbing slowly but steadily, we skirted the attenuated finger of the lower lake, passed the swift-flowing narrows above, and came out at the end of the afternoon upon the firm, pebble-paved beach loop ing in the easterly arm of the upper, or main, Bow Lake.
