Item 5, total coal used, is the locomotive miles, item 25,multiplied by the coal per engine mile, item 26. Item 6, total terminal coal, is the coal lost per terminal orenginehouse movement, item 4, multiplied by the number ofenginehouse moA-ements, item 2. Item T, coal used on road, is the total coal, item 5, less theterminal coal, item 6. The terminal coal is often of considerable amount. In theexample shown it is over 500 tons per month. Item 9, coal used per hour on road, is the coal usefl onroad, item v, divided by the hours on road, item S. Item 10, coal burned ])er stp ft. of grate area per hour, isthe coal per hfmr, item 9, divided by the sq. ft. of grate area,item 3. Item 11, water exaporated ]jer sq. ft. of grate area per hour,is obtained from item 10 by reference to a set
