waste material, and Yithin recent years
1t was estimated that the cost Of re-
moving this waste from the furnaces
of Great Britain was about $500, ,0Ot
annually.
Now a considerable portion is utilized
as a substitute for artificial porphyry
| in the construction of buildings. and
for street pavements. Paving stones
are made from it for the streets OF
Metz, Brussels and Paris. Good bricks
are also made from it and 1t can be
manufactured into a cement equal to
the best Portland.
Mr.. Kittredge says a very important
innovation in the metallurgical indus
try Is the utilization Of the waste gases
of blast furnaces for working gas en-
gines. This improvement Is shown to
mean, by a theoretic calculation, an
additional profit Of $1.25 on each ton
OF pig iron production. and this means
that Germany alone, the only country
where the utilization Of these waste
gases has as yet been effected, gain
of more than $1O.OO0,OOO on her entire
wrought iron production.
The report shows that all the pro-
ducts Of lumber and timber formerly
wasted are now turned to some utility
and some Of the new products are OF
considerable value. OF this class Is
sawdust, which was formerly consid-
cred an absolute waste material and
was allowed to float down stream OF
was thrown In a heap and disposed or
A way has been found Of preparing
this material which gives 1t value
far above that Of solid timber. BY
the process the particles Of sawdust are
formed into a solid mass capable of be-
ing moulded into any shape and Of re-
ceiving a brilliant polish and possess
ing a durability and beauty Of appear
ance not found in ebony, rosewood OF
mahogany. Mr.. Kittredge says that
artificial woodworks has most prom
ising future.
The production of acetic acid, wood
naptha and tar from sawdust Is one OF
the latest enterprises in Norway, fac
tory being now in operation at Fred
rikstad capable Of distilling 10000 tons
OF sawdust in year. 1t also manufac-
lures charcoal briuuettes from saw
dust.
| BY a recent English patent, sawdust
may be so prepared as to be non-in-
nammable and may then be applied to
the jacketing of boilers and used fol
similar other purposes.
Experiments have been made by
which a high yield Of sugar has been
obtained from birch sawdust, and alco-
hol can be profitably distilled from
either coarse or fine sawdust, the pro-
duct being of high quality and trifiing
impurities contained in 1t being sus-
ceptible of ready removal.
The utilization Of the needle-shaped
leafiet Of the pine tree, either alone OF

terly with success, to produce an arti'

ries that convert the pine leaves into

Other factories have been erected ir
different parts Of Europe for similar
use Of these leaflets. The products
made from pine tree leaflets have beer
exhibited at a number Of expositions
where they have attracted great atten'

for stuffing mattresses and articles OF
furniture in place Of horsehair, FOL
manufacture in hygenic fabrics fol
medicinal use and for articles Of dress
such as underclothes, chest protectors
etc.
Attempts have been made very re.
Gently in Oregon to make use of these
leaflets by reducing them to fibrous
conditions suitable for mixing witt
cotton to be spun into yarn for weav'
ing. In the preparation Of the textile
material an oil is produced which Is
employed as a curative agent and or
tentimes as a useful solvent.

| THE NATIONAL GAME.-While idline
upon the deck of an ocean steamship
recently, the attention Of a group OF
voyagers, comprising several prominent
Americans and two Engmsh baronets
was directed to the fact that no less
than a dozen passengers were deeply
engrossed in books relating to bridge
whist. Whereupon the merits of that
fascinating game were discussed and
differing questions made 10 the question
az to whether it would retain, by virtue
of inherent worth, its present extraor-
binary popularity. The most interest
