CHAPTER XXVII.
CLOSE by the Lion of Lucerne is what they call the "Glacier Garden,"—and it is the only one in the world. It is on high ground. Four or five years ago, some workmen who were digging foundations for a house came upon this interesting relic of a long departed age. Scientific men perceived in it a confirmation of their theories concerning the glacial period; so through their persuasions the little tract of ground was bought and permanently protected against being built upon. The soil was removed, and there lay the rasped and guttered track which the ancient glacier had made as it moved along upon its slow and tedious journey. This track was perforated by huge pot-shaped holes in the bed-rock, formed by the furious washing-around in them of boulders by the turbulent torrent which flows beneath all glaciers. These huge round boulders still remain in the holes; they and the walls of the holes are worn smooth by the long continued chafing which they gave each other in those old days. It took a mighty force to churn these big lumps of stone around in that vigorous way. The neighboring country had a very different shape, at that time,—the valleys have risen up and become hills, since, and the hills have become valleys. The boulders discovered in the pots had traveled a great distance, for there is no rock like them nearer than the distant Rhone Glacier,
