Test Of Explosives.
The permissible explosive. equal to
one-half pound or 40 per cent nitro
gIycerine dynamite, will be first placed
in the gallery. Within will be 1873
| pounds of fine coal dust distributed
uniformly throughout with 20 pounds
on a wooden bench at the mouth OF

| permissible explosive no explosion Of
coal dust is anticipated. The same
experiment, however, will be repeated
for the President and this time black
blasting powder will be used as the
explosive. An explosion of coal dust
is expected to follow the firing Of the
black powder. Immediately after the

gas in coal dust, affects birds much
more quickly than men. When the
birds show distress 1T is a warning
