VERY early in the history of man
came the necessity of moving
things from one place to another.
To-day the most successful boiler
houses—those with the highest effi-
ciency and lowest working cost—are
using “ Bennis ” Automatic Coal and
Ash Handling Plant combined with
“ Bennis ” Stokers. Complete schemes
prepared free to any requirement, and
behind every one is the successful
record of three quarters of a century’s
experience.
