INT IS SUITABLE
IN CLEARING LAND
Explosive is Safer Than
Dynamite-Less Affected
by Changes in
Temperature.

Last winter shortly after the arm
istice was signed, | realized that
there would come campaign in con-
nection with the use of salvage war
materials. At that time | ordered a
quantity of INT for test purposes.
/ desired at this time to go out and
make necessary field tests. However,
In view of the fact that all publicity
on the subject and the word of al
most all authorities was that INT
was not desirable explosive for land
clearing purposes, this was not
approved. After looking up bulle-
tins of the u. S. Government Depart
ment and getting opinions of various
explosive experts, ! issued the state
ment as to their advice in the mat
ter. At the same time | Indicated
that tests would be made as soon as
possible to determine the disability
under actual Wisconsin field con-
ditions. Since tile winding up of the
land clearing special, / have been
working on this explosive. l find
that without doubt INT is disable
explosive for land clearing and that
its desirability will depend upon the
cost at which it can be placed in the
hands of the user. The following
brief summary indicates the results
of our field tests and these may be
depended on as indicative of the re-
suits which may be expected under
Wisconsin conditions:
l. INT is an acceptable explosive
for land clearing. 1t is not detonated
by bullets from high powered rife
being shot into the cartridges. 1t is
very much less sensitive than the dy-
NANTES ordinarily used.
2. TINT does satisfactory work.
While it is somewhat quicker and
more scattering in it's action, it is en-
tirely disable in this respect, and
such quickness, while perhaps not de-
sirable, is not an obstacle in connec-
tion with its use.
3. No poisonous effect or harmful
effects on the health of the user fol-
lowed our work with it. -Four men,
including myself, have handled this
explosive in bulk, cartridging it
and using it in 1.any ways and finally
decorating it and inhaling more or
less of the smoke and fumes, and to
date we have not any of us expert
enced so much as headache. Smoke
and fumes, while considerable at
first, disappear quickly.
4. We have easily detonated SO
moisture of this TINT with water,
with either a No. or No. 8 cap.
The No. cap will detonate at 1O%
moisture. 1t is absolutely sure that
moisture in the quantities ordinarily
encountered in land clearing opera
tions will not materially affect the
operation of INT when properly
cartridged.
S. Ordinary variations in t0mpera,
ture have no effect on INT as far as
we could determine. TESTS made
with temperature from 80 to 88 de-
grees Fahrenheit.)
6. While we have not been able to
determine any definite figure as to
the value of using No. s cap yet, we
are sure that better results will be
obtained from the use of the larger
cap. The No. cap, however, has
not failed to detonate dry INT and
in case it were impossible to get the
No. cap, the No. would detonate
the explosive but we strongly urge
the No. cap.
I. We find that it requires about
75% as much INT as is required of
ordinary dynamite, as used in land
clearing. This latter point indicates
