The American Woods: Exhibited By Actual Specimens And With Copious Explanatory Text, Part 7 Summary:

124 Pages
Plates included PREFACE TO PART VII.
Part YII AMERICAN WOODS is a continuation of the woods of the
Pacific slope, and most of the woods represented in it were gathered at
the same time with those of Part YI the first installment of the
woods of this region and it was expected when that appeared that
Part YII could be brought out soon afterward.
It is with great regret that unforeseen interruptions have prevailed
to delay its appearance until this date, but they were circumstances
which we confidently expect will not retard the sequence of the
remaining Parts of the series.
For information aiding me in the collection of the woods of Part
YII, I wish to express my gratitude to Mr. Samuel B. Parish, Prof,
and Mrs. J. Gr. Lemmon, Mr. and Mrs. Brandigee and Miss Alice
Eastwood. I am under special obligation, too, to Mr. Chas. F.
Sonne, Prof. Chas. II. Shinn, Prof. Wm. K. Dudley and Mrs. J.
Morrow for material, with vouchers for identification, forwarded to
me since my return from the field; and to Pres. C. P. Huntington, of
the Southern Pacific Railroad Company, I am under great obligation
for courtesies extended which have very materially aided me in my
work.
It is with special delight that I find myself able to include in Part
YII the sections of an endogenous wood, the Yucca arborescens, and
I feel that their appearance will be greeted with perhaps equal delight
on the part of our patrons. The only other endogenous woods with
which we have experimented, as yet, are. the Cabbage Palmetto (Sabal
palmetto), of the southeastern States and the Washington Palm ( Washingtonia
fill/era) of California. With these we were unsuccessful in
making sections of sufficient strength to serve our purpose, but we
hope that future experiments may yet enable us to include those
species in AMERICAN WOODS, as their structure is most interesting.
The Yucca sections we have found naturally strong enough to
enable us to mount them in the specimen-pages, excepting the transverse,
which we have reinforced by immersing them in shellac var
nish. Should any improvement upon our method of treatment occur
to any of our readers, whereby the sections might be rendered tougher
without being discolored, we would (in behalf of all who study our
wood-sections, as well as ourselves,) be greatly obliged for -the information.
We desire it especially in connection with our further experiments
on the Palms, in which the fibro-vascular bundles are strong
and hard and the intervening parenchymatous tissue is very delicate.
It would seem as if some chemical treatment might toughen the
weaker tissue, but that is^ a question which we will have to leave to
sonie well-disposed chemist to answer.
