The friend last named also selected from the glacier of the Aar, at the request of Alexander Agassiz, the boulder which now marks his father's grave. With unwearied patience Mr. Mayor passed hours of toilsome search among the blocks of the moraine near the site of the old "Hotel des Neuchatelois," and chose at last a stone so monumental in form that not a touch of the hammer was needed to fit it for its purpose. In conclusion I allow myself the pleasure of recording here my gratitude to him and to all who have aided me in my work.
