234. Thus the winter motion of the Mer de Glace near the Montanvert is, in round numbers, half the summer motion.
235. As in summer, the eastern side of the glacier at this place moved quicker than the western.
[§ 34.] Motion of the Grindelwald and Aletsch Glaciers.
236. As regards the question of motion, to no other glacier have we devoted ourselves with such thoroughness as to the Mer de Glace; we are, however, able to add a few measurements of other celebrated glaciers. Rear the village of Grindelwald in the Bernese Oberland, there are two great ice-streams called respectively the Upper and the Lower Grindelwald glaciers, the second of which is frequently visited by travellers in the Alps. Across it on August 6, 1860, a series of twelve stakes was fixed by Mr. Vaughan Hawkins and myself. Measured on the 8th and reduced to its daily rate, the motion of these stakes was as follows:—
MOTION OF LOWER GRINDELWALD GLACIER.

237. The theodolite was here planted a little below the footway leading to the higher glacier region, and at about a mile above the end of the glacier. The measurement was rendered difficult by crevasses.
