RECEIVED THEIR DIPLOMAS.

The Members ores, III. H. g., Become
Graduates OF Old Hillhouse-Many

ceIlent Music Under Professor Jep-
sons Direction - The Hyperion
Packed to Overflowing.
One hundred and fourteen more young |
ladies and gentlemen can now call them
selves graduates of Hillhouse high school.
Last evening Superintendent Curtis spoke
the words which made them graduates and
presented them with the diplomas they
have 80 long and faithfully labored for
The Hyperion was crowded with the per-
ents, friends and acquaintances of the men,
bers of the graduating class when the grad
uation exercises began at 7:30 O'Clock by |
the introduction of the class by Principal |
Isaac Thomas. In few we'll chosen and
appropriate remarks he introduced the |
class of '93 to the members of the board of |
education, who sat in boxes 1 and at the |
right of the stage. He then introduced the
class to the audience, saying that 1t was
rather unusual to introduce children to
their parents, but yet when the parents
found that their children were doing SO
well they were willing to have them intro
duced as graduates of Hillhouse,
"The Mountain Air" q waltz song, was
next rendered by the members of the class
under the direction of Prof: Jepson. 1t
was very beautifully rendered.
The first Grafton of the evening was de-
Hvered by Robert Ernest Hume, son of
Rev. Mr.. Hume, missionary in India, on
'sSome Recent Inventions" He spoke of
the great progress that was continually
being made In science, and alluded to
many of the latest mechanical devices.
One of the mechanisms he spoke of was a
device for signaling. Electric lights raised
high in the air and operated by a keyboard
| much like typewriter and with the Morse
alphabet made communication over long
distances, both on land and sea, possible.
Another instrument by which q message
sent from New York can be written out on
| paper in Chicago promises to rival the
telephone. In conclusion he said: "1f
you should wake up some morning and find
written in flowing letters on the armament
| these words, Are you preparedF' do not
be alarmed. On closer inspection you will
probably find 1t to read, Are you pre-
psred for RANT If you, are not, stop at
Jones' and buy an umbrella This will be
so if the device is practical by which large
flaming letters can be thrown on the
heavens, making of the sky one grand ad-
vertising board" Mr.. Hume's paper was
highly interesting to all.
Miss Elizabeth A. Campbell then fol-
lowed in an essay on the development of
found on the fourth page of this paper.
The next essay was by Miss Harriet ].
Austin and was entitled 'Does Education
Increase Happineae?" and was a most in
teresting and instructive discourse. highly
creditable to the young lady and to the oc-
| casion.
The hallelujah chorus from Beethoven's
orstorio "The Mount of Olives" which
followed, was finely rendered.
Miss May Tomlinson Potter followed in
an illustrated essay on Electric Locomo-
tion." The lecture was illustrated by q
number of experiments which were shown
to the audience on a screen by means of
| the stereopticon.
This was an exceedingly interesting lee
ture, as it was on a subject which is es-
pecislly pertinent at present, and was the
only essay on scientific subject except
Mr.. Hume's. 1t was most warmly sp-
plauded, and Miss Potter, with her assist
ants at the stereoptioon, are to be con-
graduated on the excellent manner in
which 1t was conducted.
ELECTRIC LocoMorIoN.
"The aspects of nature" says Tyndall,
provoke in man the spirit of inquiry.
It's outward facts are insufficient to satisfy
his mood. He cannot be content with
knowing that the light and heat of the sun
illuminate and warm the world. He is led
irresistably to inquire what is heat and
what Is light. As the eye Is made for see
ing and the ear for hearing and the human
mind for Observation-Disclosures phenomena
of the material universe" The spirit of
inquiry especially characterizes the present
age. All the grand scientific achievements
of our day have resulted from the ire
| pressible exercise of this endowment. But
while scientific investigation is being
pushed in every conceivable direction,
probably no other phenomena of nature SO
universally excite interest and curl
osity as those which result from
the action of that powerful and
mysterious agent called electricity.
And yet in spite of the interest felt hardly
any other subject is to most 80 little known.
Within the last quarter of the present CEN
| tury an almost countless number of cleo
invented and have come into common use,
but very few of those VINO use these in
ventions have any distinct idea of what
electricity really is, how it Is obtained and
how it Is made to do mans work. Con-
6ning our attention now to a single Illus
tration, the citizens of New Haven are
freely using their new electric car facili-
ties, but the mechanism and how the mo-
ton of the cars is obtained is not generally
Understood.
A full explanation of the principles of
electric locomotion Is, however, quite sim
pie, and 1t will be my endeavor, with the
aid of few experiments and illustrations,
go to present the subject that 1t will no
longer seem to any mystery. Next fol-
lowed an interesting account of the prog
ress of electricity from the year 900 B. G.
up to the present date. Our attention
must now be confined to current electric
BILE of doing work, and which is used
in all practical machines. The chemical
heating and magnetic effects of electricity
were then demonstrated, also the different
discoveries of Galvani, Farsdsy and many
other scientists. After tho experiments
which we have seen I trust the dynamo
will seem very simple and the way in
which it produces electricity perfectly
plain. Then followed q clear and concise
electric motor. Various theories have
been from time to time been held concern
ing the nature of electricity, but all cave
one have been found more or less fnoon-
sistent with known facts and have there
fore been abandoned. The exception is the

question by the leading soientiats of the
world. It believed that electricity is q
certain condition of the ether, supposed
substance unlike ordinary matter, which is
thought to fill all space to the remotest
bounds. It is necessary to suppose the
existence of this so-called ether in order
to explain how the heat and light of the
sun is transmitted to us through space.
The essay concluded with q well balanced
discussion of this latter theory.
Miss Maud Ella Goodwin then followed
in a defamation, "The Legend Beautiful
which she rendered with dramatic effect
and excellent elocution.
The humorous glee "Jack Horner" WAS
the next number, and was finely rendered.
Miss Mary Louise Kennedy's essay on
"Women of the Nineteenth Century" was
the next in order, and she delivered 1t in
an impressive manner. It will be found
on the fourth page of this paper.
Miss Clara Augusta Brockett's essay, en-
titled ''Nothing Is So That Is &c." next fol-
lowed. Miss Brockett's essay was a most
bright and original effort, and we'll de-
served the praise which 1t won.
The class then rendered the chorus,
"Come, Let Us Sing" from Mendelssohn's
95th psalm, with Miss Harriet ]. Austin as
soprano soloist. Miss Austin has a voice
of surprising sweetness, and must have
been a surprise to many in the audience.
She rendered the difficult solo part in
