engineers, the civil and the military. Engineers in those days were
chiefly concerned with the making of surveys and the construction of roads
and bridges. The steam engine had not yet been made a commercial
possibility, therefore there was almost no machinery in existence, and
such little as there was did not require a professional engineer for its
designing or operation. Nothing was known of electricity. Very little was
known of chemistry and almost nothing was known of industry as it has been
organized to-day. Since that time there has been an almost incredible
development along all of these lines. As the result we now have almost as
many kinds of engineers as there are classes of industry. There is the
civil engineer, the mining engineer, the construction, the irrigation, the
drainage, the sewage disposal, the gas production, the hydraulic, the
chemical, the electrical, the mechanical, the industrial, the efficiency,
the production, the illuminating, the automobile, the aeroplane, the
marine, the submarine, and who knows how many other kinds. Indeed, there
are also social engineers, merchandising engineers, advertising engineers,
and even religious engineers. Naturally, it requires a slightly different
kind of man to succeed in each one of the different branches of
engineering, and it would be too great a task for the reader to try to
wade through all of the qualifications here. It would also, no doubt, only
result in confusion and a lack of understanding of the real fundamentals.

Fundamentally the engineer should be medium in coloring. The extreme blond
is too changeable and usually not fond enough of detail to succeed in a
profession which requires so much concentration and accuracy. Practically
all successful engineers have the practical, scientific type of forehead.
By this we mean the forehead which is prominent at the brows and, while
high, slopes backward from the brows. Usually those succeed best in
engineering who are medium in texture. The fine-textured individual,
however, if he is qualified for engineering, will take up some of the
finer, higher grades of it and make fine and delicate material or
machinery, or will engage in some form of engineering which requires only
intellectual work. Practically all successful engineers are of the bony
and muscular type or some modification of this type. This is the type
which naturally takes interest in construction, in machinery, and in
material accomplishment and
