Making twelve feet one inch of coal, exclusive of partings. Three 
samples of the upper bench, to represent different parts of it, were 
analyzed by Professer Wormley, and the average is given in No. 1 of 
the table below. No. 2 of the same table is the average of five analyses 
of samples of the thick middle bench.
