The bottom of this boiler is divided by concentric par- titions, which stand up (as shown in fig. 6) sufficiently high to prevent the liquor from boiling over. These par- titions have openings from one another at opposite sides, so as to make the course a sort of labyrinth, a is a re- servoir of liquor prepared for the operation ; Z> is a pipe or tube descending from the reservoir, conducting the liquor to that part of the boiler marked c, which is the commencement of the race. From hence the liquor flows through the channels, as shown by the arrows, progres- sively traversing the whole surface of the bottom; so that the full eflPect of the fire is exerted upon small por- tions of the liquid, which causes the evaporation to pro- ceed with great rapidity. The residue of the liquor then passes off by the dis- charge-pipe d, contrived to slide, for the purpose of regu- lating the quantity and depth of the fluid intended for the

and this pipe should be in such proportion to the
