FILTERED WATER BECOMING HARp.-A friend ho
cistern for collecting rainwater, and has divdedof
q portion with wall, consisting of one thckneSd
soft-bumed or jobbing bricks, through the pores Of
which all the water has TO filter before reaching the
pipe and rising to the pump. The filter is perfectly
successful in clarifying the water which comes up de-
Eghtfully clear but to surprise, has from the rs
continued to be- to all ntents and purposes, hard va.
ter although the concern has been in use some year.
The soft bricks are laid with common cement as are
the bricks of the cistern itself. How does soft rain.
water become impregnated with calcareous or Otbef
material which gives it the properties OF hard water b
simply filtering through baked clayl
HARRIss RoPE MAcHISE.-Mr. John Harris o!
Hoosc Falls, n. y, has invented style Of machhs
for making rope now on exhibition at the Aston House
which appears as compact as that exhibited IN the
Crystal Palace last FALL but differing from very ma
teriay in its ability to vary the twist BY this machine
the largest ropes may be laid up, if desires ard any
desired degree of twist draught, ETC., may be gve'
MS desired The days of the Old-fashiOned long rof
walks would seem to be numbered. The cordas
made on this small machine on exhibition il made
iute represented as difficult material TO work. but
as free from inequalities any tendency to kink q
can well be imagined. We advise our cOrdage mani
facturers to give it an early examination.
EVENING ScHooLs.-The free night schools Oft this cit
will commence with October. Let no mechanic whon
rets the lack of opportunities in his earlier days
acquire substantial information and training neglect
attend The schools Are not for boys and girls ar.
but for all and the studies are Of that practical SA
directly applicable to practice. You may Learn ania
metc. writing, book keeping mechanical draughtn
and public speaking by attending some of them.
FAY's HooK-TAG.-Mr. Samuel b. Fay Of this CT
has invented new method Of ticketing goods, whh
he has had patented. BY this invention the preseI
aborious and Insecure method of attaching marks
goods is entirely superseded. metallic eyeet u d
serted in the edge of suitable card, through whic
passes metallic hook shaped to be easily attache
to goods of all sorts and securely that accident,
separation is impossible These tags are prepared
every convenient size, and are furnished at 70 low
price that they cannot fail to come into immediate %
general use.
| PAPER FROM Moss.-A DR.. Terry Of Detroit ha
been experimenting half tun of NOES obtained
the Lake Superior region, and according TO The Ckre
land Ploindeol,r, ains that il makes beautiful WIN
paper without any peculiar process. The moss
represented to exist in great quantities on lse Roy
and several other localities in the vicinity, and
procured at very moderate cost.
LIDDLEs GAs-TIGHT FURyAcE.-Mr. John Lido
of this city has patented form of air-heating iunal
which appears most admirably adapted to secure a
the advantages of the most expensive styles Of ho
water heating with all the economy of fuel and dimir
shed first cost pertaining to the most auded styles
furnaces Its great feature consists in its very exteI
sve and equally heated surfaces to act on the air. tn
absence of tubes and consequently Of joints, and th
moderate hight required which latter feature not onl
enables Il very powerful and efficient furnace to b
