ration. Thofe pins whigh are intended to 
fivike the raw flax or hemp in the firft in- 
ftance, are about two inches im length, 
and fet inthe barrel-or body of the porcu- 
pine, at about the fame diftance as thofe 
ufed in the hand- Bo for flax, &c. of 
the faite kind, ard gradually ipcreafe in 
lensth and Fnenels round thé whele cir- 
cumference of the barrel or body of the 
porcupine : the longeft pins are about a 
quarter of an inch eet than the fhorteft, 
and the fineft pirs are fet about the fame 
finenefs as thofe uted for finifhing the !ame 
kind of flax or hemp by hand. And as 
the taw is colle&ed upon the pins of the 
poecupine, the pieces or bars of iron or 
other metal, called droppers, fall down 
upon the tow; and as the porcupine re- 
volves round its own axis, thefe croppers, 
by their own weight, fall down, and- oar 
dually pufh the tow from the points of the 
pins, as they advance in their progreffive 
sobs round their own axes, but.are 
prevented trom falling too far by a plate 
at each end of the porcupine, in which 
the ends of the droppers flide. Here is a 
figure fhewirg the plate, the grooves, and 
dropper, falling down and puthing off 
the tow, and the dropper reftared to its 
place, and leaving the pins at liberty for 
acting in the hemp. 
We cannot follow the\patentee through 
his whole defcription, for the want ‘of 
plates, to illuftrate the fubje&t. Thofe 
who with for more particular information 
on the fubje, may be referred to the {pe- 
cification, in which every thing will be 
found, fully explained. 
eT 
MR. EDWARD STEERS’S (TEMPLE), for 
an Engine producing a Force by the Im- 
petus which the Parts of a fluid Body 
have to an equal Altstude. 
This invenrion is faid to contain a new 
method of giving activity to a bedy of 
water or other liquid contained in it, fo 
as to produce a force arifing froma well- 
known property of the prefflure of liquids 
in all directions, which may be conveni- 
entiy applied: to the purpole cf working 
machinery. «The method confilts in fud- 
cenly producing or inereafing an’ inequ?- 
lity in the aliiiude of the parts of the 
fluid body contained in the engine, by the 
defcent and afcent of a pipe, cylinder, or 
other veffel, capable of holding a liquid 
by either turning ona boilow | profes aia 
joint, or water-way, which connects it 
with another cylinder or veflel, or by turn- 
ing in an orifice of the other cylinder or 
lately enrolled. O34 
veffel, or by having a flexible pipe or flid- | 
ing pipe (fimilar to the joints of a tele- 
fcope) or other/water-way, conne&ting it 
with the other cylinder or veflel, fo that 
it can be raifed and lowered. 
The weight of the pipe, which is made 
to afcend and defcend, can be balanced, 
therefore the power neceflary to ratfe and 
lower it is no nrore than what is fufficient 
toturnabalance. ‘* Sincethen,”’ fays the: 
' patentee, “ (he powerneceflary to produce 
the force is but ttle, while the farce pro- 
duced is very great, Tam of opinion that 
the engine may be made’ to continue its 
‘aétion by its own energy; for 7 think a 
part of the force produced may be made 
to {upply the producing power, by means 
of the cog wheels.” 
Obfervations.—We falpe&t Mr. Steers 
is too fanguipe in his expectations of the 
productive powers of this invention: we 
underitand: perfectly the principle and 
theory on which it is founded, but the 
weight of the warer ia the pipe wiil pre- 
vent its being railed or lowered fo eatily 
as he expects.

MR. ABRAHAM UNDERDOWN’s (sPA- 
FIELDS), fora Mode of making Flour 
without Grain. . 
We fhall prefent our readers witha de- — 
feription of Mr. a eat invention 
in his own words :—‘* [take turnips, po- 
tatoes, serie white-beety and Jerufa. 
lem artichokes, and grind or grate thenr 
fine: I then put the fubftance into water, 
and let it remain there feveral hours; E- 
then ftrain off the water, and add frefh 
water in quantity fofficient to cover the 
fubfiance; which proceis I continue to re 
peat until the water pours off quite clear. 
Then I ftrain and prefs the. water from 
the vegetable fubftance, which I then dry 
on akiln, or other proper convenience. 
When the fubftance is quite dry I grind 
i¢ in a corn or other proper mul, until it _ 
becomes fine flour. Either of the above 
vegetables alone, or any two or more -of 
them mixed together, and prepared as be- 
fore fpecined, will anlwer the purpofe. 
The foregoing defcription is for the mak- | 
ing coarfe or common flour: when I make 
fine or beft\flour, I pare or peel the rind 
off the vegetables before I grind or grate 
them.’ 
Odbjfervations.—The patentee would 
have done well to have pointed out the 
important ufes to which this patent flour, 
made without corn, is applicable.
