In order to keepthe mash from burning a chain g is rotarily re-ciprocated along the channels by means of thebar G, the gear E and the crank shaft e. Variousmodifications of this construction have beendevised. The advantage of the still lies in sub-mitting the mash in a thin current to the action.

Hence perfectequilibrium should be established between thevaporizing heat and the condensing cold. Thequantity of vapor must not be greater or lessthan can be condensed. If fire is too violent thevapors will pass out of the worm uncondensed. If DISTILLING APPARATUS. 61 -A the fire is too low the pressure of the vapor is notgreat enough to prevent the entrance of air, whichobstructs distillation. As a means of indicatingthe proper regulation of the fire, the simple littledevice shown in Fig. 21 may be used. This consists
