PROCESS

OF

MALTING.

75

ture

as

near

approaching

145°

as

possible

;

it

i&

the

most

favourable

to

the

quality

of

the

malt.

In

fact,

this

temperature,

which

is

also

that

of

mash-

ing,

occasions

in

the

wet

grain

a

new

formation

of

sugar,

in

small

quantity,

it

is

true,

but

this

influence

of

the

kiln

is

not

without

producing

good

effect

on

the

subse-

quent

operations,

and

the

temperature

of

145°

is

attended

with

the

greatest

success.

The

combustibles

most

gene-

rally

used

for

the

purpose

of

drying

malt

are

coke

or

distilled

coals

;

such

as

that

furnished

by

the

establish-

ments

of

hydrogen

gas,

or

even

that

proceeding

from

the

distilleries.

Next

to

that

comes

the

vegetable

coal,

which,

if

it

can be

procured

at

a

reasonable

price,

is

very

suit-

able

for

the

purpose.

After

this

comes

the

ash-tree

coal.

This

species

of

combustible

makes

little

or

no

smoke

when

burning,

and

exhales

sulphurous

vapours,

which

are

not

at

all

obnox-

ious

to

the

quality

of

the

malt.

The

grain

increases

greatly

in

bulk

by

the

operation

of

mashing

;

this

aug-

mentation

may

be

rated

at

about

one-eighth

or

ninth

part,

and

their

specific

gravity

decreases

in

proportion

;

specific,

because

the

real

loss

sustained

in

weight,

during

the

fer-

mentation

of

grain

on

the

malt-floor,

is

not

easily

per-

ceived

;

but

as

it

occupies

after

this

operation

a

greater

space

under

the

same

weight,

it

is

easily

conceived

that

it

does

not

weigh

so

much

under

the

same

bulk.

The

reader

being

now

acquainted

with

the

process

of

malting,

and

with

that

of

mashing,

as

also

with

the

effects

of

these

operations,

let

them

now

be

applied

properly.

Of

all

kinds

of

corn,

rye

is

the

one

principally

used

for

distillation.

Other

corn

might,

it is

true,

equally

be
