saturated with water, it cannot be raised and formed by
the methods above described.
In such cases the peat is dredged from the bottom of the bog by means of
an iron scoop, like a pail with sharp upper edges, which is fastened to
a long handle. The bottom is made of coarse sacking, so that the water
may run off. Sometimes, a stout ring of iron with a bag attached, is
employed in the same way. The fine peat is emptied from the dredge upon
the ground, where it remains, until the water has been absorbed or has
evaporated, so far as to leave the mass somewhat firm and plastic. In
the mean time, a drying bed is prepared by smoothing, and, if needful,
stamping a sufficient space of ground, and enclosing it in boards 14
inches wide, set on edge. Into this bed the partially dried peat is
thrown, and, as it cracks on the surface by drying, it is compressed by
blows with a heavy mallet or flail, or by treading it with flat boards,
attached to the feet, somewhat like snow shoes. By this treatment the
mass is reduced to a continuous sheet of less than one-half its first
thickness, and becomes so firm, that a man's step gives little
impression in it. The boards are now removed, and it is cut into blocks
by means of a very thin, sharp spade. Every other block being lifted out
and placed crosswise upon those remaining, air is admitted to the whole
and the drying goes on rapidly. This kind of peat is usually of
excellent quality. In North Germany it is called "Baggertorf," i. e.
mud-peat.
Peat is sometimes dredged by machinery, as will be noticed hereafter.
12.--_The Moulding of Peat._
When black, earthy or pitchy peat cannot be cut, and is not so saturated
with water as to make a mud; it is, after raking or picking out roots,
etc., often worked into a paste by the hands or feet, with addition of
water, until it can be formed into blocks which, by slow drying, acquire
great firmness. In Ireland this product is termed "hand-peat." In
Germany it is called "Formtorf," _i. e._ moulded peat, or "Backtorf,"
_i. e._ baked peat.
The shaping is sometimes accomplished by plastering the soft mass into
wooden moulds, as in making bricks.
13.--_Preparation of Peat Fuel by Machinery, etc._
Within the last 15 years, numerous inventions have been made with a view
to improving the quality of peat fuel, as well as to expedite its
production. These inventions are directed to the following points, viz.:
