The method employed in 1906 to measure the rate of flow was identical with that used on the Illecillewaet. The accompanying table gives the results so far secured.

In 1901, when we first visited this glacier, we marked on the bed rock the extent of the tongue, and also took test photographs from a large boulder high up on the right moraine. This work was repeated in 1904 and in 1906. The work of the Scientific Section of the Alpine Club will demonstrate the rate of flow.

The recession from 1901 till 1904 was 89 feet, an average of about 30 feet per annum. From 1904 till 1906 apparently the glacier was practically stationary.
