AVERAGE COST OF REPAIRS OF BABCOCK & WILCOX BOILERS IN THE PAST SEVENTEEN YEARS.

Sufficient replies were received to include over 100,000 horse-power, the repairs to the heating surface of which, due to all causes, have averaged less than 5 cents per horse-power per year, of 300 days at 12 hours per day; boilers which have run night and day being credited with the extra running time.
