Iuppoyyp GrIpE FOR SAws.-lt Is common 70 steady
both circular snd recprocang saws BY pressing lightly
scair the Doth sides thereof near the points where
The teeth erter the wood. Such guides tend to keep
the blade perfectly steady, induce the teeth 10 cut
smoothly AID without removing so much OF the wood
TT unequal thickness Of the say however, requires
that rexbe guide shall be either 80 close az to pinch
in some place and induce heating or 20 loose a. to but
impa.ectly accomplish their purpose. MIR. Orrs Rce
OF Cincinnati has lately paterted what seems TO be avery
desirable improvement, consisting OF elastic guides
which press at all tunes lightly against the blade and
Weld to all inequalities but the yielding il only to
ce:tan yer, limited extent beyond which its resistance
is very obstinate and sufficient to prevent any possible
"runnibg" One ssw is now running with this device
affixed ani is demonstrated that saw much thinner
than u.ua and consequently wasting considerably less
material IN saw Gust, be made to serve without
any counter balancing disadvantage The guide Is got
no in the form of short hollow tube, and the rubbing
material is wood saturated with oil.
PAPER AND RAGs-Italy is the greatest ragmaker
or rag collector and the bted States are the greatest
parer makers in the " worh As general fact We make
our own paper but import large proportion OF the
material OF the whole quantity imported, takipga
series Of years together, Italy furnishes about two
Thirds. but whether this is due TO the abundance OF
fax and hemp in the Italian States and the liberal
habits Of the people with regard to clothing or to the
trade with Greece ard Turkey, which would make
them seve o1ly collectors, is not explained IN the
orc mary sources of statistical information 1t Is GER
tain that but little poper manufactured IN either OF
those countries.
The annual consumption of paper IN the United
States is constantly increasing and now stands at about
go 900 600 pounds or something ten pounds per
individual England produces now about III 900 900
pourds. of which about 1900, 900 are exported aad
l6 COO 900 consumed. France produces about lJ6,-
coo 900 pounds Of paper and exports some 100000
Neither France or England imports more than quar-
ter or half million pounds. The annual consumption
in both Great Britain and France reaches therefore
only about 500 600 900 pounds pounds per head,
less than hall much in proportion to the population
only about 600 900 more in the aggregate than 10
the United States. 1t requires about II pounds o.
rsgs to make pound Of paper. The 2'O,OOo,ooo OF
psy er in the United States therefore requires about
337 100000 pounds Of rags annually. The rags lm-
ported from all countries is now &C, OO0O 600 pounds
which taves about 300 900 as the quantity cleaned
within our own lims.
ECONOMY OF FUEL-The President Of the Pacific
M ssouIiJ Railroad certifes to the fact that train OF
three passenger with baggage and express car,
has been hauled l25 miles with the consumpeon OF
Only one cord Of ordinary oak wood. The grades are
at some points 45 feet 70 the mile but for the greater
portion Of the dstarce only ten to twenty feet, With
considerable curvature We believe this psTfor
TO be unprecedented. The speed IS neither ex-
treme y rap Ior very slow the whole time required,
inc udpg stoppages being seven hours Iae mules run
TO each cord Of wood usually range between ~ and
iO On the Erie road where heavier trains ere run,
but the most careful economy practiced the average
ranges between 81 and 33l miles.
RAILEoAD AccIDEsTs.-Ehe recent sad fase Of D.
II. Dore Esq, Superintendent Of the longest rau-
road in the world the Illinois CENTRAL IN consequence
Of falling under the wheels of his own tram, tends 10
the Lotion that accidents of this nature, whch
Usually occur in getirg upon trains IN motion or ''dV
cling from one car to another, are wholly due 10 a
want either Of intellect care experience IN railroad
travelling. Some one who proeses to have Kept
record Of the deaths from this source during the past
twelve mouths, reports the number to be more than
ninety.
Power, HEAT AND MAcsETrsM.-Tnere is believed
to be certain definite relation existing between heat
and power that can be changed into the other.
Power only changed into hest only when it il apr
repty INFLATED by friction; ard to avery limited eA-
tent heat changed 10 mechanical power, by the AID
Of q steam. engine. NJ FOucault Of Paris has Ia'eiy
given q view of the relations between msgnet-
i'm and heat by me- ans of his gyrvecope. Aaso ana
