Civil engineering, three generations ago,
was summed up In surveying, road making,
masonry hiilldlng and designing heavy ma
chlnery, and Its masters could he conver
sant with the whole recorded horizon of the
profession. Now It Is divided Into rocog
nlzcd llelds, each of which requires a llie
tlmo of study and concentration. There Is
mochanleal, electilcal, mining, naval, rail
road, geodetlcal, hydraulic, structural, mu
nicipal and sanitary engineering. The
scope of the first four Is too elahorate nnd
technical for present
consideration. (' e o

The railroad engineer has already brought
his train speeds up to a possible rate of 100
miles an hour for short distances. Ileyond
this tho limit of safe endurance of his
materials Is not far distant. The dangers
to llfo and property nre so much multi

for further Increase that the maximum
speed will hardly become notably higher.

within a half score of yea is the develop

tho wants of adjacent manufacturers and

Now power can be transformed to elec
tricity and can bo so advantageously ap
