The Stump Digger
Another new machine we have
built is one which has been born out
of hard experience in the jungle. In
hunting a route through the jungle,
both in Africa and Peru, I have gone
along making fine progress carving
out a trail, tearing down the vines
and thorns, knocking down the trees
and pushing them to one side, of
course dodging the real big ones,
when all of a sudden we come upon
a small stream. Crossing the stream
is no problem; you simply c u t
through the bank, make a fill across
the stream and go across, but when
you get to the other side there is
another bank, probably only ten or
fifteen feet straight up, but the ques-
tion is how do you climb that bank. If
you had your machine on top of the
bank you could lower the blade and
cut down through it and make a road
up in probably twenty or thirty min-
utes, but you can't get your machine
up on top. If you were in a well de-
veloped country, you could probably
go up or downstream a ways to findoiai Plaee With R. G. LeTourneau

hemmed in by the jungle on every
side and can't do that.
Then, too, several times, even
though I did not encounter a stream,
I came to a steep hill that the ma-
chine could not climb. Sometimes we
have been able to hook a cable to a
tree up on top and winch the machine
up the steep slope, but many times
the timber on the slope was too thick
for that, so we have worked out a
gadget on our machine that will en-
able it to walk right up a straight22 Sunday, Eureka, California

are in the way as it pioneers its way
up the bank. We call it the Stump
Digger.
This machine has an ordinary land-
clearing blade on one end, but on the
other end it has a revolving cutter.
This cutter is in reality another
wheel like the wheels that drive the
machine, only instead of the tire
being on it, there are sharp cutting
spikes welded to the rim and face of
the wheel.
This wheel has the electric motor
