PASTE DIAMONDS.

The Providence journal. which
comes from the vicinity Of immense
cheap iewelry factories, has the follow
ing on "paste diamonds" which are
simply glass of great purity:
When imitation diamonds were in
troduced, it was found that to cut
glass precisely like q diamond did not
produce the sparkle characteristic of
the diamond; therefore to secure this
the fiat surface on the top of the dia-
mond was made pyramidal on the imi-
tation, and, of course, ended in point.
BY certain laws of light this pyramidal
surmounting of the glass provided for
tie required distribution of ray surface
to produce the diamond sparkle, or
something akin to it. A real diamond
is never cut with the pointed apex, and
hence it was possible always to dis
tinguish the real from the spurious.
But after time the buying public
learned this little circumstance about
the cutting process. and other means
were resorted to. The glass was cut
precisely like the diamond, and the
sparkle was given to or provided for it
by coating of white foil applied to
the lower side of the glass The set
ting of many diamonds is arranged in
such way that the buyer may see the
under side of the gem. This was over
come by arranging the setting as to
prevent inspection Of this kind, which
could not be done unless the stone was
dismounted, if we may use that term.
"With these facts known to the buy
er of diamonds, he need not be deceiv-
ed except in the latter case, where the
setting hides the under surface, and If
he has any doubt about that he can let
it alone. But the object of imitation
diamonds is not to deceive buyers If
it was they would not be offered for
two dollars No one, however defci-
ent in diamond criticism, need be de-
ceived in buying diamonds. No deal
or of any repute ever attempts to sell
imitation for real diamonds. No repu-
table man ever thought Of it. His rep
utation and occupation would soon be
gone. There are very few persons who
buy trinkets who do not test their
wares at other than the buying place,
particularly If the gem is costly one,
and It is certain that no one was ever
presented with jewelry Of presumable
worth who did not set out ut once to
learn it's purity and value, and very
disappointing it has doubtless been to
find in some cases that the gold or dia-
mond was only brass or glass"

prefers twenty parts of gypsum, three
or four of quicklime and one of carbolic
acid, sprinkled thnly over the leaves
when wet with dew or rain, repeating
the application as often as necessary,
which may be number OF times.
It has been the practice Of the Inte-
rior Department to hand each Indian
reservation over to the religious teach
ings of one particular denomination, so
that the converts became Methodists,
Baptists, or something else, purely ac-
cording to chance and never from
choice. This is now to be changed.
Under the new arrangement the Ro-
man Catholic Church will go into the
field with large force of priests.
A compound is described for the
preparation of what are termed safety
envelopes. That part of the envelope
covered by the flap is treated with q
solution of chronic acid, ammonia,
sulphuric acid, sulphate Of copper, and
ine white paper. The flap itself Is
coated with solution of isinglass ia
acetic acid, and when this Is moisten-
ed aud passed down on the under part
of the cnvelop, solid cement is form
ed, entirely insoluble in acids, alkalies
hot or cold water, steam, &c.
