In concluding his address, Professor Waters referred to the experiments that 

 had been going on at St. Louis to determine the best use to which inferior coals 

 could be put, and to ascertain the relative cost per horse-power generated by coal 

 and by producer-gas. These experiments were still going on, and in America the 

 use of gas-engines was rapidly increasing. He thought the Government, through 

 the Mining Department, should take steps to ascertain what use^ could be made of
