'All sizes of 'White Oak' prepared coal are loaded into railroad cars with loading booms to minimize breakage and preserve the best appearance of the coal. It would be useless to carefully mine and screen our coal if we did not use proper care in loading it into the railroad cars. These booms lower to the bottom of the car when it is first placed under the tipple for loading, and raised from time to time as the car fills up. Note how perfectly screened this lump coal appears on the boom! Not a sign of slack to be seen. Treated for dust if desired.'
