But while the methods to be used in these reports have been worked out, not all of them are being carried on permanently, the reason being lack of funds. The latest detailed annual report on the movement of coal is for 1918, and it is uncertain when another can be prepared. The current reports are inadequate and the reports on stocks and consumption are issued only at irregular intervals. Even the annual reports of production leave untouched many subjects of vital importance. We have no quantitative information, on a national scale, as to the amount of coal cleaned; the amount of mine-run, slack, and prepared sizes produced; the mechanical equipment of the mines; the depth of the coal workings; the distance the miner must traverse from mine mouth to working face; the dip of the coal seam; the tonnage produced by long-wall or room-and-pillar methods; the quantity of coal in the ground lost to the nation each year, in the roof, in pillars, because of squeezes; or the quantity lost in thin seams not now minable which are broken and fractured by the mining of lower seams. We do not know accurately how fast electrical haulage is replacing animal haulage underground, what progress the loading machine is making in relieving human backs of the labor of shoveling coal into cars. Of course, any operator and any miner knows of these things in a general way in his own locality, but such scattered, hazy, local knowledge will not suffice. We must have accurate information, national in scope. In the realm of the financing of coal companies the ignorance of the public is almost complete. We do not know the capital value of the coal deposits, nor the degree of concentration and control of ownership of mines or mineral. We do not even know who owns the coal beds. There is no list of the landholding companies who as landlords absorb in many districts the economic rent paid by the mines working favorable seams. We do not know the prevailing royalty rates, we do not know whether or not there is a soft-coal trust. The most basic of our American industries moves in fog by day and blackness by night.
