. British Antarctic expedition, 1907-9, under the command of Shackleton : reports on the scientific investigations ; geology. ked coalfields of the whole of New South Wales. It is possible, therefore, that in the far future, if deglaciation makes this coalfieldaccessible to man, it will prove an important factor in the worlds supply of fuelwhen existing coalfields have been largely exhausted.* If the Beacon Sandstone formation is considered the equivalent of the Permo-Carboniferous coal-measures of Australia, it seems strange that no trace has beenobserved of any glacial beds associated with it. Mawson has already suggested thatthe abundance of undecomposed felsjmr in the sandstone implies a dry climate,perhaps like that of a tundra. It is of course conceivable that tundra conditionsmight jjrevail at a pole when intense glaciation was being experienced in compaia-tively low latitudes, as unless the polar regions could be fed under those circumstances * Some deduction should be made fiom the quantity of exploitable coal on account of the damagecaused to the coal by the intrusive sills of dolerite.
