velopment OF much farm land
has been boulders. Ihis Is
particularly true in New'England ana
has been the most common cause
of the abandoned farms OF that sec
ton. Now. however. the giant crush
ing force OF dynamite is being en-
ployed to make possible the easy
cultivation Of that vast territory
The three methods OF boulder blast
ing are "mud-capping,' snake-hol-
,ne~ and "blocS-holing." The quicker
methods. Though requiring more ogna-
MITE than block-hohng are mud-cap-
ming and snake-holing. Mud-cappinB
is ALSO termed dolby shooting or
"blistering" aud the effect Is or thc
crushing blow Of an enormous sledge
hammer. In.mud-capping the charge
is placed at the point where one
would naturally strike the boulder II
a sledge hammer were employed. The
dynamite is packed in o solid mass
Inv Sitting the paper cartridge shells,
hut is not spread over any more OF
the surface OF the boulder than Is
necessary. A blasting cap, crimped
onto the fuse, is placed In the center
of the charge and the whole covered
with six inches Of damp clay or sand.
The material is pressed nrmly over
the dynamite. care being taken not TO
cover the free end OF the fuse. When
a boulder is deeply embedded in the
ground, the earth around II is loosen
ed or dug away before the blast is
fired.
In the snake-holing operation mole
is made with a crowbar or DIRT anger
under a fiat or hollow side OF the rock
and the same method as used IN
stump-blasting is followed. BLACK
