Show PLAN TO MAKE EKIQUETS OF LIGNITE WASHINGTON, July 7. Ia briquets bri-quets of lignite, the government bureau of mines believes it hat developed a fuel aupply that will be, of immense value to the west, where high grade coal eaa ba obtained only at excessive coat. A powerful machine brought from Germany haa solved the difficulty whleh heretofore has limited tha manufacture of briquets the cost of the pitch necessary nec-essary to bold the coal dust together. Lignite is a poor form of brow a colored col-ored coal found in great abundance ia North and booth Dakota, Montana, Texaa and other western at a tea. Ita tendency to alack soon after being mined -makes it troublesome to transport, trans-port, aad it does sot burn readily on account of the presence of between SO aad 40 per cent of moisture. The b reaa of mines conducted experiments st Williston, N. D., and developed a furnace that would burn lignite aatis- faetorily. -Now that the experiments have gone far enough to indicate that briqueta ean be made successfully at low cost, the bar te transportation of lignite seems 'to have been removed, i Charles L. Wright of the bureau estimates es-timates the rest of briquets loaded at tha mines at !ll a ton in Texas, 3.53 ia North Dakota, aad $3.24 ia California. |
