in a ball room, and the chemical
properties of various malt and vinous extracts in another room; but
the philosophical reason why certain engineering work is done in the
way it is, and the proper way in which new work shall be done of a
similar character and original work of any kind carried on, can only
be learned by cultivating your powers of observation and ruminating on
the facts collected in the privacy of one's own room, away from the
allurements provided for those who have nothing to do. No one would
recommend you to so separate yourself from the world as to sacrifice
health and strength, or to become a recluse, even if you did learn all
about a certain thing.

Remember, however, that the men who have accomplished most in this
world worked the longest hours, and any one with a regular occupation
must utilize his leisure hours to obtain prestige. The difference
between one man and another of the same natural ability lies entirely
in the amount of his information and the facility with which he can
use it. Life is short, and you must realize that now is your
opportunity. If any diversion in the way of pleasure or even certain
kinds of congenial work is offered, consider it in connection with the
question, "Will this be conducive to my higher aim?" This implies that
you have a higher aim; and if you have it, and weigh everything in
this way, you will find that every moment of exertion adds something
to your storehouse of information and brings you nearer to the
accomplishment of that higher aim.

In closing, we thank the ladies and gentlemen present for their close
attention to details of special interest only to those engaged in
technical study or practice.

We congratulate you, young gentlemen of the class of '87, for the
success you have thus far obtained, and trust that you will persevere
in well doing and win greater success in the future. We need hardly
state that all that has been said was in a spirit of kindness, and we
feel assured that much of it has been seconded by your parents, to
whom no less than to all parents here present off or on the stage, the
speaker not excepted, a serious, thoughtful problem has been, still
is, and will continue to be to many, "What shall we do with our
boys."--_Stevens Indicator._

HEATING MARINE BOILERS WITH LIQUID FUEL.

We were recently witness of an experiment made at Eragny Conflans on
the steam yacht Flamboyante.
