extracted text (Extract Text): KNOWING that poison
gas seldom rises more than
thirty feet above ground |
level, a British inventor |
worked out an odd device |
designed to draw fresh air
into gasproof shelters on |
or under the ground. Re-
sembling a giant accor-
dion, a special hand-op-
erated bellows sucks fresh
air into the shelter through |
a flue pipe that extends up
forty feet above the ground.
Said to be foolproof, the
apparatus draws in air at
the rate of 400 cubic feet
a minute.
