"The strongest upward draught pulsated with the gusts
of wind and ranged from 30 feet to 54 feet per minute, a down draught of
equal intensity occurring at intervals at the same spot, notwithstanding
the fact that the air was rushing in at the inlets below the floor at
the high velocity of 785 feet per minute. The temperatures of the drying
malt and superimposed air consequent upon the conditions thus indicated
were naturally as follows: At B, the place supposed to be hottest: Heat
of malt touching tiles, 216 deg.; heat of malt 1 inch above tiles, 167
deg.; heat of malt 3 inches above tiles 154 deg.; heat of malt 4 inches
above tiles, 152 deg.; heat of malt 5 inches above tiles, 142 deg.; heat
of malt on surface, 112 deg. At A, the place supposed to be coldest:
Heat of malt next tiles, 174 deg.; heat of malt 2 inches above tiles,
143 deg.; heat of malt 4 inches above tiles, 135 deg.; heat of malt on
surface, 104 deg.; the heat of the air 3 feet above tiles, 84 deg.; the
heat of the air 5 feet above tiles, 82 deg.
