1611.]. Znformation respecting the Culture of the Grape Vine. 15 
1807, M. Foaques, Chimiste Manufac- 
turier, as he styles himself, published the 
result of his enquiries into. the nature of 
this kind of syrup obtained from grapes 
growing near Paris, and in the beginning 
of the last yéar, the following remarks: 
41. That 4 hundred weight of the must 
of these grapes evaporated at the heat of 
“30 degrees of M. Reaumur’s thermo- 
meter, produces 125 pounds of syrup, 
-without, any art or extraneous addition, 
congealing into crystals of a spherical 
shape; and these being dried on linen 
cloths, through which all the more fluid 
Moisture passes, a quantity weighing 
about 75 pounds is left. 
2. That there remains, after the ery3- 
tals are pressed out with proper force, 
60 pounds, 
3. That after having been purified and 
refined, it yields 40 pounds of beautiful 
cassonade sugar. 
4. That, should this be again refined 
and clarified, so as to possess a whiteness 
equal to French Orleans sugar, itmay-be 
formed into loaves like. the West India 
sugar, but at a reduction of the quantity 
to 16 pounds. , 
5. That it is in this shape so compact 
and firm in allits parts, as to be able to 
bear exportation. 
6. That a single pound evaporated to 
sugar lumps, leavesonly 10 or 11 ounces. 
Il. The Reverend Mr. Schregel’s Sugar 
Srom the Stalks of Turkey Wheat.-—Se- 
veral years ago, Mr. Schregel, Pastor of 
Schwedt, tried to extract a syrup from 
the stalks of Turkey wheat, and the ex- 
periments made on a small quantity were 
very successful. Hesowed a whole acre, 
Magdeburgh measure, (about 14 acre 
English) with five metzen, (somewhat 
more than 4 of a bushel) of this grain, 
which produced about one wispel, (or 
57% London bushels,) in grain, and about 
250 pounds of leaves, at the same time 
that four horse-waggon loads of tur- 
nips grew in the intermediate spaces. 
The heads, after the grain is taken off, 
are a very profitable fuel, and yield 
‘ashes, of which one-fourth part is pot- 
ash. Mr. Schregel made a_ report 
on this subject to the king of Prussia, 
offering to publish instructions relative 
to the best mode of cultivation, and to 
explain the means by which the whole 
might be turned to the greatest ndvan- 
tage, His majesty commanded his privy 
counsellor, Mr, Thaer, to examine the 
‘facts more closely, and to report ac- 
eordingly,

SIR, 
re the Monthly Magazine of last 
month, I observe a claim to the ina 
vention of the means of relieving ships in 
distress by firing a shut fastened to a 
rope, made by Mr.Carey. I think it but 
justice to others to mention, that near 
twenty years ago, I remember the same 
mode was suggested by Mr. Edward 
Brim, a brazier, of Portsea; and the 
experiment was actually tried, as I un- 
derstand, in the presence of two naval 
officers ef the first erminence. A similar 
experiment was tried here about fifteen 
years ago, by a serjeant Bell, of the Aruil- 
lery. How far Mr. Carey, or Captain 
Manby, is entitled to the merit of the dise 
covery, may therefore be very fairly ques- 
tioned. Wis

SIR, ‘ 
N reply to Whistensis, on the game of 
Whist, I should conceive when A.A. 
win two double games, and B.B. one 
single, A.A, have gained four points: for 
this reason, viz. A.A.’s two double games 
constitute a rubber, or five points; but 
B.B. having won a single game, deduct 
it from A.A. s score, which leaves four 
points. 
If A.A. win two doubles, and B.B. 
one double, three points are in favor of 
A.A, likewise, when A.A. win one dou- 
ble, and one single, and B.B. one single, 
A.A. gain three points: when A.A. win 
one double and one single, and B.B. one 
double, A.A. gain two: when A.A. 
win two singles, and B.B. another sin- 
gle, A.A. gain two: when A.A. get 
two doubles, and B.B. none, A.A. must 
gain a bumper, which consists of five 
points; when A.A. get two singles, and 
B.B. none, A.A. gain three: and, in the 
instance of “A.A. winning two singles, 
and B.B. one double, A.A. consequently 
gain only one point thereby.
