Edwards, Mill-street, Lambeth, to witness an experiment made'
with a Steam Engine, constructed by them on Mr. Wolf's Pa-
tent Principle, to a•ceitain what quantity of Wheat could be
ground by the said Engine with a given quagtity of Coals. The
Engine was in good working condition, the sniU-stoues in good
order, and the experiment was made with two pair of stones,
French burs, four feet diameter. The Engine was worked with
proper care and attention for ten hours awl 41 minutes, and in
that time ground 33 bushels of Wheat, Winchester measure,
with one bushel, three pecks, and 14 lbs. (say 161 lbs.) of Cuals
of Colllngwood Main. The weight of the Wheat was 59 lbs. reat,
per bushel. The Engine is estimated at nine horses power.

On the 12th day of July, 1811, an experiment, similar to the
above, was performed with Woolf s Engine; at Woolf and Ed-
ward's, when upwards of 34 bushels of Wheat were ground into
Flour, with two bushels or 16R pounds of Newcastle Coals. The
Wheat was of the weight of 5911b5. per bushel. Certified by

London, July 19, 1811.

This is to certify, That w., the Subscribers hereto, were pre-
sent on the Premises of Woolf andF.dwavis, at Mill street, Lam-
beth, on Friday the 19th day of July, 1811, to witness au cape-
ritnent made with a Steam Engine of Arthur Woolf's Patent Con-
str.n-tion, to ascertain how much Wheat could be ground into
flour by two pair of French bur stones, of four feet diameter each,
attached to the said Engine, with a given quantity of Coals, and
that the following was the result. Worked the Engine.four hours
and I t minutes, and burnt 3 bushels of NewcastleQuals, weighing
entilhs. During the above time and with the above quantity of fuel,
one pair of the above Stones ground 36 Bushels and 44.11b5. and
the other pair 24 and '2slb. making together Gl Bushels
and i3,11b5.; and it is tier opinion, that if the second pair of Stones
had been in as good order as the first, there would have been
ground with the above fuel at
_least 7Si Bushels The Wheat
weighed Milt» per bushel.

From the above Certificates it appears, that with one of news.
Bolton aid Watt's beat Engines of eight horses' power, not quite
six bushels of wheat, Winchester measure, can be ground unto
flour with one bushel or 84 pounds of Newcastle coals ; and that
with the same quantity of coals, Woolf's nine horse Engine cam
grind Irons :A/ to 24 bushels of the same wheat. In other words,
Woolf's Patent Steam Engine of nine horses power can hft from
40 to 45 million.; of pounds oi:e foot high, with one bushel o
coals.—F.np.ioes of greater power can lift considerably more wit
the same quantity of fuel.
Engineers, by applying to she Patentee, Arthur Woolf, No. 2,
sv/tilt-place, Lambeth-walk, may be accommodated with Li-
cences to construct these Engines on equitable terns'.
