may not have got into print, of his own physical strength. He spoke 

 as if it were then an old experience to him. Whether he were twenty- 

 five or thirty-five when it happened, it shows how admirable was his 

 training and his physical constitution. He had been with a party of 

 friends somewhere in eastern Switzerland. They were traveling in 

 their carriages; he was on foot. They parted with the understanding 

 that they were to meet in the Tyrol, at the city of Innsbruck. Ac- 

 cordingly the next morning, Agassiz rose early and started through 

 the mountains by this valley and that, as the compass might direct 

 or his previous knowledge of the region. He did not mean to stop 

 for study and they did not. But he had no special plan as to which 

 hamlet or cottage should cover him at night. Before sundown he came 

 in sight of a larger town than he expected to see, in the distance, and 

 calling a mountaineer, he asked him what that place was. The man 

 said it was Innsbuck. Agassiz said that that could not be so. The 

 man replied with a jeer that he had lived there twenty years, and had 

 always been told that that was the name of the place, but he supposed 

 Agassiz knew better than he did. Accordingly Agassiz determined 

 that he would sleep there and did so. The distance was somewhere 

 near seventy miles. I know it gave me the impression of a walk 

 through the valley passes at the rate of four miles an hour, maintained 

 for sixteen or seventeen hours. 



In later life Agassiz made to us some prophecies in which we may 

 trace his enjoyment of the finest physical health and strength. Health 

 and strength indeed belonged to everything which he said and did. 



Among other things he said, twenty-five years ago, that the last 

 years of our century — the twentieth — would see a population of a 

 hundred million of people in the valleys of the upper Amazon. I like 

 to keep in memory this brave prophecy because I am sure it will come 

 true. 



James Dwight Dana 



By President ARTHUR T. HADLEY

It was my privilege to know James Dwight Dana intimately during 

 my early years. To boyhood's imagination his figure typified the man 

 of science; his life personified the spirit of scientific discovery. Wider 

 acquaintance with the world has not in any way dimmed the bright- 

 ness of that early impression. 



The services of the geologist are to-day recognized by every one, 

 and sought by all who can afford them. If he would make a voyage 

 of exploration and discovery, the resources of the world of finance are 

 placed at his disposal. No such aids were given two generations ago.
