RESULTS OF THE COAL TESTS UNDER THE BOILERS. 
., 
The accompanying table shows some of the most important practic 
results of the tests of coals burned under the boilers. In each test an 
effort was made to operate the boiler at a point very near its rated 
capacity. In some cases the coals tested presented difficulties which 
made it impossible to accomplish this result. The various coals were 
tested in the order of the "test numbers" given in column 1, and tests 
of coals from widely separated localities were frequently made or 
successive days. 
Attention is called to " rate of combustion" at which the coals wer< 
burned. To those familiar with tests of this character it will be evi 
dent that the coals were for the most part burned at a rate calculatec 
to give approximately the most favorable results. 
All of the chemical results reported in this table were furnished b; 
the chemical laboratory in charge of Prof. N. W. Lord, which i 
sufficient guarantee of the accuracy. 
The " horsepower developed by the boiler," recorded in column 1J 
refers to the standard boiler horsepower and is the evaporation of 34.
