The following two methods of marking lanes through minefields, and
routes for troops moving through the desert have been recommended as being
most effective. They are simple to construct, and are not apt to be
a. For Marking Lanes through Minefields
Remove the lid from an ordinary tin can, and fill it with Diesel oil to
within one-half inch of the top. Fix a piece of wire screen over the top and run
several pieces of ordinary twine through it. This twine should project about
three-quarters of an inch over the screening. The lamp will burn
for 8 to 10 hours after being lit.
The lamp is then covered with a larger tin can. Cut an arrow in the side
of the larger tin can, and cover on the inside with a strip of oiled paper. The
arrow is obscured from air observation by means of a strip of metal. Experiments
have shown that the light can be plainly seen at night at a distance
of 150 yards. The lamps should be staggered on either side of the lane.
b. For Marking Routes for Troops
Remove the lid of a gas or water can, half-fill with sand, and saturate the
sand with undiluted gas. When lighted, this will burn for about 1 1/2 hours. It
can be seen for about 550 yards.
