USEFUL PROJECTS. 
P. S. I have written in such 
haste, that I have forgotten to men- 
tion that the mixture ought to sur- 
round the part affected with the scab. 
Method of curing Butter, practised 
in the Parish of Udney, and its 
Neighbourhood. 
From the general View of the Agri- 
culture of the Counly of Aberdeen.

‘the Board.of Agriculture, by J.

PXHE following mode of curing 
& butter is practised by some in 
the parish of Udney, and that neigh- 
_bourhood, whic! gives totheir butter 
a great superiority above that of 
others. 
Take two parts of the best com- 
mon salt, one part of sugar, and one 
part of saltpetre; beat them up to- 
_gether, and blend the whole com- 
pletely. Take one ounce of this 
composition for every sixteen ounces 
_of butter, work it well into the mass, 
,and close it up for use. 
I know of nosimple improvement 
in economics greater than this is, 
-when compared with the usual mode 
of curing butter by means of com- 
mon salt alone. -I have seen the 
experiment fairly made, of one part 
of the butter made atone time being 
A21 
the other. The butter cured with 
the mixture appears of a rich mar- 
rowy consistence, and fine colour, 
and never acquires a brittle hardness, » 
nor tastes salt; the other is compa- 
ratively bard and brittle, approach- 
ing more nearly to the appearance 
of tallow, and is much salter to the 
taste. IJ have eat butter cured with 
the above composition, that had 
been kept three years, and it was as 
sweet as at first; but it must be 
noted, that butter thus cured «te- 
quires to stand three weeks or a 
mouth before it is begun to bewsed. 
If it be sooner opened, the salts are 
not sufticiently blended with it: and 
sometimes the cooluess of the nitre 
will then be perceived, which totally 
disappears afierwards. ; 
The pernicious practice of keeping 
milk in leaden vessels, and salting 
butter in stone jars, begins to gain 
ground among some of the fine 
Jadies in this county as well as else- 
where, from an idea of cleanliness. 
The fact is, it is just the reverse of 
cleanliness; for, in the hands of a 
careful person, nothing can be more 
cleanly tban wooden dishes; but, 
under the management of a slattern, 
they discover the secret, which 
stone-dishes indeed do not. 
In return, these latter communi- 
cate to tbe butter, and the milk, 
which has been kept in them, a 
poisonous quality, which inevitavly 
proves destruciive to the human 
constitution. To the prevalence of 
this practice, I have no doubt, we 
must attribute the frequency of 
palsies, which begin to prevail jso 
much in thie kingdom ; for the well 
known effect, of the poison of lead 
is, bodily debility, palsy, —death ! 
_ thus cured, and the other part cured 
with salt alone: the difference was 
-anconceivable: I should suppose that, 
_ sim any open market, the one would 
sell for thirty per cent. more than 
Dd3 ANTIQUITIES.
