THE ECHO DEsTRoYERs.
Besides this trade, modern science mas
created lot of others. One consists In tne
destruction of echoes. These in churches,
meeting halls and even large rooms are SO
powerful at times as to prevent all enjoy
ment. They are destroyed by spinning
wires not far from the ceiling at points ana
lines where the waves of sound are most
easily shattered. A much more dimcult
calling and one of late creation is that OF
micrometer making. For mathematical
purposes these must be made so hne as 10
measure the 341, 900 of an inch. On such a
scale the hair of the head is as large as an
express wagon. 10 do this demands educa-
tion, technical skill, mechanical and mathe-
matical knowledge and unfailing eyes and
hands. There are not more than hve men
in New York, or more than 80 in the coun-
try at large, who have the qualities requisite
to make q standard mierometer.
Another new trade which has hardly
made start which promises great perform
ance is the manufacture of liquid and solid
carbonic acid gas. The process Is very
dangerous and the flushed product very
difficult to handle. 1t produces the deepest
known cold. A few drops poured into a
glass of water will convert it into ice. A
single drop upon the skin will produce a
blister like molten iron. It is used on a
small scale for refrigerators and also as
preservative of milk, fruit juices and pre-
serves.
SECONDHAND WEDDING PRESENTS.
The secondhand trades have increased in
number. Wholesale dealers in clothes have
been reinforced by those in boots and shoes,
in hats and, odd to relate, in wedding
presents. Those ia boots and shoes repair
what they buy from the peddlers, fix them
up until thev have quite decent appear
anee, and then send them in large quanti-
ties to various distributing points about the
land. The same practice is followed BY the
wholesale dealers in secondhand hats. The
man whe trades in secondhand wedding
presents acts upon the theory that every
beneficiary is bound to receive duplicates,
and upon it has opened large store where
brides or other donees can buy, sell or ex-
change whatever presents they have no use
for. The business, though young, has as
sumed immense proportions and has paid
more than handsomely its ingenious pro-
prietor.
Three novel trades are mechanical in
their nature. One consists in making sheet
music for the blind. Two skilled machin.
lists have obtained quite reputation by
converting coins, large buttons and similar
objects into boxes. They do q large bust
ness. The burglar utilizes these buttons
and coin boxes by filling them with a fine

other class of customers, and carry these

TRADES IN SOCIETY.
Society exigencies have created or de-
veloped few new callings of late years in
this city. The chaperone, once so much
ridiculed, is now an established institution.
She has been followed by the professional
escort, who will take unprotected women to
theaters, balls, dinners and excursions for q
dollar or upwards per night, according to
the style demanded. This present season
the escort has been followed by one who
may be called riding and driving COM
panion. He is supplied by frst-clsss
stable, dresses in a frstclass manner, is a
thorough rider and driver, and perfectly
familiar with the city and its environs. 1t
is needless TO remark that he gets first.
class price.
Society women who are troubled with
superfuous hairs now employ what are
known as ladies' BARRIERS, who are generally
graduates from the tonsorial establishment
of some prominent hotel. Shaving the hair
on the body does not, as is commonly be-
lieved, make it grow any faster or increase
its harshness or strength. They generally
treat their patients once a month. The
trouble is not only with the lip and cheek,
but also the arms and back. A very ex-
pensive fad is having your portrait cut as an
onyx cameo. The work is very slow, diff
cult and laborious. The image when done
is permanent and will last ior centuries.
There are enough people in New York who
enjoy this kind of extravaganza to give
constant employment to five cameo portrait
