 the advantage was in favor of the Atlanta Method as far as time is

ANALYSES COMPARING THE BITUMINOUS 



COALS OF NORTH CAROLINA AND 



TENNESSEE. 



H. B. BATTLE. 



The high percentages of sulphur and of sa^h render bituminous 

 coals of North Carolina inferior to others on the market, and on 

 this account it is doubtful, even if their extent and locality would 

 justify, whether North Carolina coal could compete with that of 

 Tennessee or Virginia. 



The analyses following compare North Carolina bituminous coal 

 with the coal of Tennessee, while other analyses are appended as a 

 matter of interest : 



I. Represents the average of eleven analyses of samples of bitu- 

 minous coal from as many different localities near Farmville, Chat- 

 ham county. N. C. 



II. Shows the character of the natural coke found near the same 

 place. 



III. Average of two analyses of samples from the Taylor place 

 near Gulf, Chatham county. 



IV. Gives mean of two analyses of semi-anthracite from Chatham. 



V. Average of seven analyses of semi-anthracite from Rocking- 

 ham county. 



VI. Analyses of merchantable Tennessee bituminous coal sampled 

 from a pile of fifteen tons sold in Raleigh.
