This tube is driven horizontally into a heated rick with a mallet or beetle, and at once affords the means of ascertaining the temperature of the stack, V' which is done by passing a thermometer on. / .^- the space h ; thus a thorough ventilation of the stack in the direction of its length is secured. Cross or transverse ventilation a b c B might be also secured by having openings not filled in with com in the side walls of the kiln, although these will not be so much re- quired, as a good amount of air will pass through the corn which makes up the sides.
