The Days of a Man [;i894 



Lassen s volcano with a small crater at the summit, still hot 

 Butte ^^^ erupting at times. Though previously quiescent 

 for half a century, Mount Lassen has again become 

 intermittently violent, several considerable outbreaks 

 having taken place within the last decade. Some 

 fifty years ago an overflow of lava down the east 

 side blocked a stream and formed a small lake in 

 the forest. Out of it the smothered trees still rise 

 gaunt and naked from the water. Below the Butte 

 on the south side, a small geyser basin, locally 

 known as "Bumpus' Hell," has been produced by 

 the contact of underground streams with hot rocks. 

 Near by is Vinegar Lake, a large, very sour pond 

 impregnated with sulphurous acid.

An During the whole of 1894, as well as in the four 



inclusive preceding years, I gave all my available time — 

 American that is, all uot demanded by the University or by 

 fishes outside lectures — to the most extensive and the 

 most trying of my scientific writings, "The Fishes > 

 of North and Middle America." ' This work I had I 

 begun in 1889 in Bloomington, at Dr. Goode's ^

OF 



THOSE ICHTHYOLOGISTS OF THE PAST 



WHO HAVE STUDIED 



AMERICAN FISHES IN AMERICA 



IN TOKEN OF 



"the ONLY REWARD THEY ASKED — 



A GRATEFUL REMEMBRANCE OF THEIR WORK " 



Here followed a list of fifty-one pioneer naturalists. "Middle" Instead 

 of "Central" America was adopted as a more logical term, at the request 

 of Dr. Goode. The same phraseology was also used by Ridgway for his 

 corresponding treatise on birds.
