Caption on back reads, 'White Oak Stove size is surely growing in popularity, and why not? It is an ideal size for laundries, bakeries, hot water heaters and similar uses. It is uniformly sized, free from slack and impurities and can be washed if desired.'
Caption on back reads, 'The most popular size smokeless coal marketed today is egg size and White Oak is proud of its egg coal. Neither too large, nor too small; perfectly screened and without a single impurity are reasons for the popularity of this wonderful domestic fuel. Note the even size of this egg coal as it is passing over the loading boom into the railroad car. Treated for dust if desired.'
The acid test of coal preparation is to lift your boom to clear and direct the critical eye of the camera against your coal to determine whether or not you are loading your coal properly. This is just what the camera man did in this case. No previous warning or preparation, he just stopped at a tipple, asked the inspector to lift the boom and took this picture. Note again the firmness of this coal in the railroad car; not a trace of slack or impurities.
