m, a stately
agaric, be 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 inhabiting 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
Guatemala, 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 remembrance and heartfelt appreciation.

The Author.
