diameter, II feet inches long for the after boilers
and 10 feet for the forward boilers There are three
furnaces, feet inches diameter on each boiler
making twelve furnaces In the four boilers. There
are $50 tubes in each boiler. Each boiler
feet inches high, delivering the
Is feet diameter and 30 feet high above the steam
cbnneys The total crate surface is 300 square feet
The total heating surface is 1850 square feet with
Ouf the steam chimney; proportion OF fire to crate
surface "a TO /. The ship IL furnished with donxey
boiler and two main donkey pumps, one Woodward,

which Il ysy important item IN
the IHcinc service, where coal IL always costly The
boilers have been tested cflcally, at hydrostatic
pressure Of sixty pounds which Is much higher than
usual The machinery OF the Dakota n intended 10

tanned on small consumption OF fuel
The hull has been much improved for
