Show COAL DEPOSITS OF MONTANA LOCATED ON OLD LAKE 1 BEDS The Th presence of coal in the tertiary lake beds of ot certain valleys talleys in western Montana has been be known locally for tor man many years ears S Some mo localities have uve even en c ex cx experienced cx- cx perien d brief coal booms boom most moat of at which however died before the tho coal W was developed Systematic mining of the coal is now being carried d on ha near MIs- MIs ll- ll soula Coal of ot the typo found in this region has until recently been baen thought worthless worthless worthless worth worth- less because only coal that would coke or stand shipment without slacking Blacking was wa considered of commercial value In In this part of ot the west where high grade grado coal Is scarce whore the cost of wood has reached 6 5 or more a a. cord and soft loft coal oa Imported for tor domestic use about 8 8 a aton ton tho the demand for tor cheaper fuel Is great and and the development of these heretofore I unused low Jow grado grade coals Is becoming prof prof- That Tha t these low Jow grade grado do coals may furnish furnish fur tur nish gas gaa of or good quality at a a. moderate cost and briquettes suitable for fog domestic domes domes- tic tu fuel la Is suggested by the r results of experiments with coal al of ot a similar type recently carried on at tho the University of North Dakota by E.
