At one of the larger brick works on the Rhine the experience of several years trial proved that a firing with a mixture of browncoal briquettes and raw browncoal gave better results in actual work than stone coal alone, stone coal with briquettes, or stone coal and raw browncoal, and at the time of my visit works were just being com- pleted for briquetting their browncoal for use in this manner. In using this earthy browncoal for such firing purposes, or under steam boilers and elsewhere, due a...ttention is given to the arrangement of the fire-boxes and grates to suit the fuel. If a flat grate is used the UTILIZATION OF LIGNITES. grate bars are made very narrow and with small intervals between each. The favorite grate, however, is called the "treppen rost, " and is a grate arranged in a series of steps by which the air gets proper access to the browncoal without need of a blast sufficient to carry- away the smaller particles unburned. For household purposes stoves of suitable construction for cooking and heating, using raw browncoal or briquettes as fuel, are for sale everywhere in Germany.
