INTRODUCTION 



carefully removed from the bed of loam, the decaying stump, or the old tree- 

 trunk, then turned over and over again, and upside down, every part scrutinized, 

 the structure in every detail attentively regarded not with repugnant feeling, 

 rather with a sympathetic interest that should naturally find all organisms in- 

 habiting our globe then in due time coming to the picture, a real picture, in the 

 book, it must surely bring both pleasure and profit. Ponder the suggestion. 

 Then, to conclude in a word, if Mr. Hard's book will induce people to learn and 

 enjoy the mushrooms that we have, it will be a success, and great will be his 

 reward.

AUTHOR'S NOTE 



IN MEMORIAM 



It is with feelings of profound sadness that I am impelled to supplement 

 the above Introduction by a brief tribute to the memory of that genial gentleman 

 and lovable companion, as well as enthusiastic scientist, the late Dr. W. A. 

 Kellerman. 



Spending his life in the pursuit of science, the Angel of Death overtook 

 him while still in search for wider knowledge of Nature and her works, and 

 with icy fingers sealed the lids over eyes ever on the alert for the discovery of 

 hidden truths. 



Quiet, reticent, and unassuming, it was given to but few to know the great- 

 hearted, unselfish sweetness of nature underlying his whole life. Yet the scientific 

 world in general and Nature students especially, recognize in Dr. Kellerman's 

 death a loss long to be regretted and not soon to be repaired. 



The foregoing "Introduction" from his pen was one of the latest, if not the 

 last of his public writings, done but a few weeks before being stricken with the 

 fatal fever which fell upon him in the forests of Gautemala, and so quickly ended 

 his earthly hopes and aspirations. 



It seems doubly sad that one so well and widely known in his life should 

 be called upon to lay its burdens and its pleasures down while so far away from 

 all who knew and loved him well ; and to rest at last among strangers in a strange 

 land. 



To this beloved friend and companion of so many pleasant days in woods 

 and fields the author of this book desires to pay the tribute of a loving remem- 

 brance and heartfelt appreciation. 



The Author.
