TRADE TECHNICIANS DISCUSS CHARACTERISTICS OF WOOD—(Continued from page 11)
lihood of our utilizing in the years to come
many of these valuable wood6, particularly for
requirements where woods of uniform density
and structure are essential.
Wood From South America
"Hard maple, for instance, is a wood that
grows in very limited areas in the United States,
and our available supply of this timber is rap-
idly diminishing. I firmly believe that many
of these unknown hardwoods of the tropics
will in time to come be found to be fully as
useful for a great many purposes as even the
mahogany and Spanish cedar of the tropics,
which have long filled many practical needs
and requirements. Just what one or more of
these woods may possibly take the place of
the hard maple I am now unable to say, but
when the time comes that you are compelled
to seek a substitute for maple, I think you
will find it in the tropics of Mexico and in
various localities in Central America.
"For various of your other requirements for
white ash, oak, elm, etc., it is not likely that
for a matter of *.wenty or thirty yCars other
woods will be required to replace them. How-
ever, the great forests of Venezuela and Brazil
offer splendid inducements for investigation of
the great primeval and untouched forests of
those countries, so that I feel warranted in
saying you have little or no occasion to be con-
cerned about a source of supply in the event
that our own American woods finally disappear.
"There is much diversity of opinion as to the
limitations of wood and its general utility,
but wood experts and those more widely con-
cerned in the manufacture and manipulation
of wood and lumber are inclined to view more
complacently the conditions that confront us,
namely, the rapid depletion of our forest re-
sources, and the prospective opportunities for
replacing the known woods of commerce from
other sources of supply. As I have already
stated, the unknown woods of the tropics of
South American countries have not found their
way to market, except in very limited quan-
tities, by reason of the fact that there has
been little occasion for the pioneering work
that is necessary to introduce them.
"The grandeur of the stately white pine, which
has been so successfully used in piano construc-
tion in years past is not excelled anywhere in
the great forest areas of the world, either in
its primitive beauty or its superb action in
every use to which it has been adapted for
commercial purposes. The only specimens of
the order of Coniferae that approach it as a
utility when a soft wood of uniformly even
growth and softer texture are required are the
sugar pine of California (pinus lambertiana)
and a species of pine which I personally in-
vestigated in 1911 in the state of Michivacan
in Mexico. It is my opinion that some of the
requirements that previously have demanded
the good old cork white pine of Maine, Penn-
sylvania, Wisconsin, Minnesota and Idaho may
be filled satisfactorily, but I am doubtful about
either of these woods ever fulfilling some of
the extremely particular needs that white pine
has served. Among the latter I choose to in-
clude the requirements for piano key stock.
Awarded first prire in many world compe-
titions during the past sixty years, the
Scbomacker Piano is now daily receiving first
prizes of preference won by its superb tone,
