It is good to revive the memory of Torrey Field Days when Professor 
Underwood went along; what spirited seeing and seeking! Will any one of 
those who were of the party of May 6, 1906, at Redding, with him as our host, 
ever forget that delightful day? The happy hunting grounds that he knew 
so well — where Pellia epiphylla was found fruiting riotously, and / ubula 
Pennsylvanica was growing in great pendulous masses on the wet, steep 
sides of the glen. Then the rest under the trees, partaking of the bountiful 
luncheon provided by Mrs. Underwood, the general feeling of friendliness, 
the bouyant life radiating from our host ! It was indeed a red-letter day ! 
A life of such constancy to an ideal wdiose accomplishment means the 
development of so many fine faculties in himself, and the advancement of 
science in the world will make us forever treasure his memory.
