- Editor's Notes
- "I beg to append herewith the statement of one day's measurement of the coal and horsepower taken and supplied by the laboratory engines, together with the diagrams taken on them. You will see that the net result shows 5 1/4 lbs. of coal burnt to the H.P. hour and 9 1/2 lbs of water evaporated per lb of coal. I think you will agree that this is fair engineering practice. The supply of steam to the outbuildings and upper floors will no doubt account for the increased coal consumption on many occasions. The total number of H.P. hours being 1145 would make an average of 48 nearly all through the 24 hours. The least activity was between the hours of 20 and 21 when it reached 88 H.P. and at that time it is safe to say one goiler would be insufficient. ### The figures can only be relied on to 10%." Yours faithfully A.E. Kennelly
