I believe the above statement to 
be correct. The condition and 
health of the milch cows is equal, 
if not superior, to any in the neigh- 
_ bourhood. 
The average of the milk is yet 
200 quarts per day, varying with 
the Weather and’ other accidental 
circumstances,

Take the bones of sheep’s trotters, 
break them grossly, and boil them 
in water until cleared from their 
grease, then put them into a cru- 
cible, calcine them, and afterwards 
grind them to powder. ‘Take some 
wheaten flour, put it in a pan over 
a slow fire until it is dry, then make’ 
it into a thin paste, add an equal 
quantity of the powdered bone-ash, 
and grind the whole mass well to- 
gether: this mixture forms the 
ground for the pannel. ne 
The pannel having been pre. 
viously pumiced, some of the mix- 
ture above-mentioned is rubbed well 
thereon with a pumice-stone, to in. 
corporate it with the pannel. Ano- 
ther coat of the composition is then 
applied with a brush upon the pan. 
nel, and suffered to dry, and the 
surface afterwards rubbed over with 
sand-paper. 
A thin coat of the composition is 
then applied with a brush, and if a 
coloured ground is wanted, one or 
two coats of the colour is added, so 
as to complete the absorbent ground, 
When it is necessary to paint 
upon a pannel thus prepared, it 
must be rubbed over with a coat of 
raw linseed, or poppy-oil, as drying 
oil would destroy, the absorbent 
quality of the ground; and the 
painter’s colours should be mixed 
up with the purified oil hereafter 
inentioned. 
Canvas grounds are prepared, by 
giving them a thin coat of the com. 
position, afterwards drying and 
pumicing them, then giving them a 
second coat, and lastly a coat of 
colouring matter along with the 
composition.
