was diftilled, and the frft diftillation 
was reCtified next day without any 
addition. ‘The produce was twelve 
gallons, of the fame quality with 
the fample. 
Tn our examination of this fample, 
we found it refembied a corn fpirit 
in flavour, but was equal to a corn 
fpirit of the beft kind, and it was a 
proof {pirit. 
The refute of the carrots weighed 
48 ttone, which, added to the tops 
and tails, made provifion for hogs, 
befide the wath from the fill, which 
meafured 114 gallons. 
From this experiment, Dr. Hunter 
draws the following comparifon be- 
tween the diftillation of carrots and 
that-of grain. 
Twenty tons of carrots, which 
will make 200 gallons of proof 
fpirits, may be bought for 161 
Eight quarters of malt, or rather 
the ‘materials for diftiliation, con- 
fiting of malt, wheat and rye, may 
be bought for 161. and will alio 
male 200 gallons of proof {pirit. 
The refute from the carrots wiil 
be g60 ftone, which, at 1d. per 
ftons, will fell for 41. 
The refufe or grains from the 
malt, &c. will be 64 bafhels, each 
bufhel weighing about three ftone, 
which, at 1d. per ftone, will fell 
for 16s. 
The Doétor, however, fuppeofes, 
that the manufacturing of the {pirit 
from carrots, may be attended with 
more expence than the manufactur- 
ing of it from malt; but imagines 
that the greater value of the refute 
may compenfate for that expence, 
and that the faving of corm for otrer 
purpoies, is an object worthy of at- 
tention and of encouragement.

Succofiful Experiment of rearing” 
Calves without Milk. From Tranf- 
adions of the Bath Society, vol. v.. 
t 
Tytherton, Dec. 3, 1789. 
SIR, 
HE following is as near a 
calculation of the expences” 
of rearing my calves without milk, 
as 1 can at preient affert.. In the 
year 1787, I weaned feventeen 
calves, in 1788 twenty-three, and: 
in 1789, fifteen ditto, I bought in 
1787, three facks of linfeed; I put 
One quart of the feed to fix quarts 
of water, which, by boiling ten mi- — 
nutes, became a good jelly; this 
jelly is mixed with a fmall quantity — 
of the tea of the bett hay fteeped in 
boiling water. 5 
Having my calves drop at dif- 
ferent times, I did not make an 
exact calculation ‘of the expence of 
this hay tea, but out of my three. 
facks of feed, I had better than two 
bufhels left at laft. I gave them 
the jelly and hay tea three times a 
day; to the boy who looked after 
them 6d. per day; the price ef the 
linteed was’ 4s. Od. per bufrel 5” 
the whole three years feed 2}. 5s. 
My calves are kept in a good 
growing ftate, and are much better” 
at this time than my neighbours’ 
that are reared by milk; they do. 
not f4'] of fo much when they come 
to grafs, 
I am your obedient fervant, 
Tuomas Crook.
