professor Jerome Hopkins in the
Newark News has very interest'nE
article on "The Utilization or waste
Materials" He says:
The inventive genius of modern times
has found no field of exercise more at-
tractive or more fruitful OF practlcal
results than that of the conversion Oh
the so-called waste products OF CIVIL
ization into things of use and beauty.
In this material aud matter-of-fact age
men OF science have found speclal
satisfaction in work of this kind, ana
the transforma tions they nave wrought
vie in their strange and marvellous
character with the achievements or the
miracle workers of the olden um9'
Over dust-heaps, piles of Stag, garbage
barrels and dumps of refuse these mou-
ern magicians have waved their wand
and 10 and behold! the despised TN
can, the battered old hat, the cast-of
shoe and the unsightly heap of dross
from mill and factory have sprung up
into all manner of comely shapes Tor
the use or enjoyment of man. Applied
science has thus realized the dreams
of the ancient alchemist, ana IN lts
crucibles the meanest and Coarsest SUD-
stances are transmitted, If not literally
into gold. yet into things which have
a high cash value.
USE OF BY-PRODUCTS.
Thus. as beginning of the list. we
have the use now made of the bN-pro-
ducts of the greatest packing houses in
Chicago, New York and other cities. II
has been stated recently that these es-
tahlishments make more money out or
the incidentals. so-called, such as the
horns. hoofs. hair and sineWs of the
animals, slaughtered. than they do out
of the meat products, Nothing from
the cattle is allowed to go to waste,
from the horns to the long hair on the
tip Of the tail. The latter is turned
into curled hair for upholstering. The
hoofs go chiefly into the kettles to be
boiled for glue. and the residue is made
into hoofmeal. a valuable fertilizer.
Even the tankage water is boiled to
extract it's fats. The coarse bones are
either carbonized and sold for sugar

and the blood is mostly dried and
turned into another aid to agriculture.
Before the horns are sold, the pith is
extracted from them, and the finest
grade of geatine is obtained from the

used for glue stock, the bladders are
sold for holding snuff. and the greater
part of the intestnes are used for saus-
age castings. The lining of the wind
pipe is also of particular value, being
used for a fancy sausage casing, and
also as a lining for pipes through

BROKEN GLASS.
A recent number of The Worlds
Progress conveys the interesting in
formation that broken glass usually
considered one of the most worthless
things, promises to become an article
of commerce. In Switzerland and
France the manufacturers of glass
brick for paving purposes has just
been taken up on large scale, and
Geneva already enjoys the distinction
of possessing several glass paved
streets. The new material gives much
a safe footing for horses The city of
Nice has also decided to put down
glass pavements The glass scrap is
first heated until soft, and then COM
pressed into brick. Glass scrap has
hitherto been converted into ornamen-
tai tile, to take the place of marble or
mosaic.
What substance seems more useless
ha,
or Stag, as it is called? But Stag is
now treated in variety of ways anG
converted into a number of usefu
things, such as paving blocks, slae
glass, Stag shingles and Stag sand. Slag
bricks is one of it's chief uses at pres,
ent, and for these there is consider.

WHAT Is DONE WITH COAL STAG
Coal Stag has been for years anothe
troublesome waste. Now, however
this is being used for building pur
