amous plant, Professor Dana turned to one of the few remaining 
who had not confessed their ignorance, with the remark, ‘You 
are from the country, you ought to know.”” And he did. 
Professor Dana’s first teacher was an ardent student of nature 
who was wont to go with his pupils on long tramps for the pur- 
pose of collecting minerals, plants and insects, and aroused in 
them much of his own eagerness for the pursuit of knowledge. 
It is therefore but just that some of the fame of his distinguished 
pupil should be attributed to him. One incident which Professor 
Dana used to relate to illustrate his teacher’s fervor as a collector 
was that when on one occasion his little party had gathered at a 
remote place more mineral specimens than they could carry in 
their hands, the master, in preference to leaving any behind, 
improvised a bag from a pair of trousers and thus bore them 
safely to their destination. 
To rehearse at this time the principles of geology which Pro- 
fessor Dana taught, or to state the opinions which he gave to his 
classes upon mooted geological questions of the day, would be 
quite superfluous, since they have been sufficiently expressed in 
his recently published Manual, a work fortunately completed 
just before his death and which came, as another has said, as 
“the worthy consummation of a long life of exceptional earnest- 
ness and success as author, investigator, editor and teacher.”’ 
But lest, in contemplating the splendor of his principal achieve- 
ments, the sidelights which revealed the man and his methods 
should pass unheeded, it has seemed to me desirable to fix and 
record them for the encouragement and guidance of those who 
may desire, however humbly, to follow in his footsteps. There can 
be no doubt that with him the tenth muse was work, in whose 
wake the other nine followed, yet the union to this capacity for 
almost unlimited labor, of breadth of mental vision, calmness of 
judgment, fertility of resources, strict integrity and loftiness of — 
purpose, did much to render it effective, and enable him to 
accomplish more than perhaps any other man of his time for the 
advancement of American geology.
