Description by Temperature Collectanea from 1796 to

Wilds America Octavo
Vo.1.p.395

In order to avoid
the expence of feeding
many (cattle] thro' the
winter, as soon as
the frost sets in they
generally kill cattle
and poultry sufficient
to last them till the
return of Spring. The
carcases are burried
in the ground and
covered with a heap
of Snow, and as they
are wanted they are
dug up, Vegetables
are laid up in the
same manner and
they continue very
good throughout the
Winter.

Longs Travels in
America 1791. p.85
The weather being
more moderate I
sent my men to the
lakes to look after
the Nets which had
been under the Ice
a considerable time
the severity of the
season not having
allowed us to examine
them for near a
Month, when to our
great mortification
they were found almost
rotten and not
a single Fish.—

Moisture is an indispensable
requisite to
facilitate putrefaction
and any substance
may be defended from
this change by compleatly
drying it. This
was performed by
Cazalet and Villers of
Bordeaux by means
of Stoves the Meat

thus prepared was
preserved several years
without having contracted
any bad flavour.

The sands and light
pervious Earths preserve
the bodies of men only
by virtue of the property
of exhausting the Juices
and drying the Solids.
From this cause it is
intire Caravans
have been discovered
in Arabia consisting
of men and camels
perfectly preserved in
the Sands under which
the impetuous winds
have buried them. ibid.

The contact of Air is
the second necessary
cause in the putrefaction
of Vegetables. It
is reported in Ephimirides

for 1787 (1687) that
ripe Cherries were
preserved for forty years
by inclosing them
in a Vessel well
luted and placed
at the bottom of a
well. 275. A certain
degree of heat is
likewise necessary the
heat between 5 & 10
degrees (43 1/4 and 54 1/2
Fah.) is sufficient to
cause decomposition.
A greater heat dissipates
the humidity
dries the Vegetable
and preserves it from
putrefaction. Too little
heat retards or suspends
it.
