The DE LAVAL

STEAM

TURBINE

THE MOST
EFFICIENT
PRIME MOVER

There is no more efficient prime mover than the De Laval
Steam Turbine—especially for Colliery Service. Simplicity
of construction, low steam consumption, close speed regu-
lation, are its most important advantages—combined with
sound mechanical construction and design. They are made
in all capacities up to 600 B.H.P. Give us the opportunity
of placing full details in your hands.
