management. His is the responsibility of example in fair dealing
and good government in the community.

In but few of its greatest works does the personality of its real
creator reach the ears of the world; the real engineer does not
advertise himself. But the engineering profession generally rises
yearly in dignity and importance as the rest of the world learns
more of where the real brains of industrial progress are. The time
will come when people will ask, not who paid for a thing, but who
built it.

To the engineer falls the work of creating from the dry bones of
scientific fact the living body of industry. It is he whose intellect
and direction bring to the world the comforts and necessities of
daily need. Unlike the doctor, his is not the constant struggle
to save the weak. Unlike the soldier, destruction is not his prime
function. Unlike the lawyer, quarrels are not his daily bread.
Engineering is the profession of creation and of construction, of
stimulation of human effort and accomplishment.
