Amesbury, Mas, has devised plan represented a.
completely successful 70 avoid the expense Of vAng
up wells and secure pure water free from lnseets and
the hike consists in sinking perforated citsrn 10
the proper depth, with two pipes thence 10 the
surface, and hlhng up with earth. A pump is coz
nected to one Of these pipes and the other the
air descepds to supply the place Of the water pumped
out.
Boiler IScRUTArIoss Mr.. Thomas Sloan Of 81
L. uis ha. patented an sttachment to steam boiler.
which is reported TO make mississippi river water 10
pure that il causes little scale. II consists Of separate
vessel in which the incoming water exposed 10 the
.4 am at full pressure, and thus raised to the fr tenn
perature before admission TO the boiler. Ali the scale
fo,ms in this heating vessel and may be readily re-
moved a. often as desired.
HAND SEEp-PLAyrER-Ar b. Boekln Of this city
has patented planter which plants by simply pressing
Il upon the earth and which alec catches up ard drops
on the srot sufficient earth to cover the seed. This
succeesful in toerably bad soils, is step ahead.
HAT WITHOUT FIkE.-Mr. W. w. Albro Of Bing
hamon this State, has patented contrvsnce Tor the
emplo, ment of quck-lme 10 cook, etc. Water !.
poured en- the lime and the dish placed thereon.
RAISING STEAM BY FRIcrIoS In the last Paris
Exhibition was cylindrical steam boiler, with large
shaft and drum in its interior around which was tightly
wound plated hemp, that on turning the shaft
rapidly by machinery outside the friction would gen.
crate heat, and thus steam be generated II this
steam be then employed TO drive an engine, it gives
out only about half the power required to generate it
but in cases where water is abundant and fuel
scarce. it might be employed to advantage for heating
purposes and il may be worthy Of notice as the frst
practical example Of on engine for changing power
into h, at while the ordinary steam engine and all IT.
substitutes are examples Of the reverse.
STEEL CAsrRGs.-The well-known establishment Of
Nsylor & Co., at Sheffield England, is now producing
cast steel forgngs Of large size by new process OF
casting the fluid metal in sand somewhat like cat
iron The product is reported in The Gfdsgor Pieto-
rial MtcAantcs Journal - a new material stronger
and sounder than perfect wrought iron, and free from
the imperecous which heavy masses of the latter
are often subject II would seem to be great desd
era.um for steamship shafts and the like.
FYGLIsH PArESrs The reduction Of cOst Of pat
ents in Greet Britain in 1852 has so increased the
nun Der that surplus OF about $50, 900 accumulstss
every year. Last year this surplus bad reached
flCO, ,ooo--eQual to nearly s5oo,ooo. II Is proposed
very seriously to reduce il still further.
BrNDIsG SHIP TixBER.-A partially successful ef-
fort uade some two years since 70 bend by newly
patented proct large sticks Of timber for marine con-
strucions has be. revived within few months un-
der the management Of a new Company, and bids fair
to be completely successful even in producing the
largest sized knees from common straight timber.
The process consists in steamng for about bur hours
aud then bending in a machine which, as the same eI-
erts very powerful nd pressure the timber forcing
the wood together endwise. We have just visited the
works, and large quantity Of timber thus pre-.
pared which, in the opinion OF our most experienced
shipbuilders, will be more durable and strong thsn
wood naturally crooked. Sticks, of white oak and
also of live oak, large II by 10 inches square,
are bent into of less than 80 inches radius
the inside 10 period Of about is minutes. new
machine is now being made in Boston, on still i'm
proved plan, which will be in operation at the works
of the Company, at Greeppoint in a few weeks.
Company has sko been formed in London, which has
already put in operation two Of the largest sized ma
chimes and is constructing tive for smaller work
