Boiler Explosions.
                   BOILER EXPLOSIONS.
                        BY CHAS. I. KING,
                 Superintendent University Machine Shop.
  In considering the subject of Boiler Explosions, I am aware
that it has heretofore received the attention of many able theorists
and mechanical engineers who do not agree in their conclusions.
That such diversity of opinion exists, is natural from the various
conditions of the matter discussed.
   What is here prepared may not be new, but the subject is of
--such--vast-importance, that even repetition may be pardonable.
   If we for a moment consider the field, we find that its extension
precludes comprehending the whole in one short paper, which
covers the subject proportionally, as the hand might cover a
table. That the astonishing developments, attained by the use of
steam in the various industries throughout the country, must be
ascribed to its universal success as a moderately cheap prime
mover none can deny; and the facility with which it can be em-
ployed in any section of the land enables the manufacturer to locate
his mills wherever desirable, and then transport to them the mo
tive power.
  Without it, he must be content with the water courses wherever
they may be found, and ever after transport the material of man-
ufacture to and from the market.
  Without it many of our large cities and manufacturing centers
could not exist to-day. Only while it is considered less danger.
ous or less expensive than other agents, can steam maintain its
now prominent position of principal motive power for nearly all
branches of manufacture, transportation, etc.
  There are considerations in connection with the present methods
of utilizing steam, which, looked upon from every point, would
indicate clearly that we are justified by no means in accepting it
as the most economical prime mover obtainable. Many unsuc-
