emain a little longer time. The machine can spread the peat over
eighteen square rods of ground--taking out one square rod of
peat--without being moved. After the eighteen rods are covered, the
machine is moved two rods ahead, enabling it to again spread a
semicircular space of some thirty-two feet in width by eighteen rods in
length. The same power, which drives the engine, moves the machine. It
is estimated by Mr. Roberts, that, by the use of this machine, from
twenty to thirty tons of peat can be turned out in a day."

Mr. Roberts informs us that he is making (April 1866,) some
modifications of his machinery. He employs a revolving digger to take up
the peat from the bed, and carry it to the machine. At the time of going
to press, we do not learn whether he regards his experiments as leading
to a satisfactory conclusion, or otherwise.

_Siemens' method._

Siemens, Professor of Technology, in the Agricultural Academy, at
Hohenheim, successfully applied the following mode of preparing peat for
the Beet Sugar Manufactory at Boeblingen, near Hohenheim, in the year
1857. Much of the peat there is simply cut and dried in the usual
manner. There is great waste, however, in this process, owing to the
frequent occurrence of shells and clay, which destroy the coherence of
the peat. Besides, a large quantity of material accumulates in the
colder months, from the ditches which are then dug, that cannot be
worked in the usual manner at that time of the year. It was to economize
this otherwise useless material that the following process was devised,
after a failure to employ Challeton's method with profit.

In the first place, the peat was dumped into a boarded cistern, where it
was soaked and worked with water, until it could be raised by a chain of
buckets into the pulverizer.

The pulverization of the peat was next effected by passing it through a
machine invented by Siemens, for pulping potatoes and beets. This
machine, (the same we suppose as that described and figured in Otto's
Landwirthschaftliche Gewerbe), perfectly breaks up and grates the peat
to a fine pulp, delivers it in the consistency of mortar into the
moulds, made of wooden frames, with divisions to form the peats. The
peat-paste is plastered by hand into these moulds, which are immediately
emptied to fill again, while the blocks are carried away to the drying
ground where they are cured in the ordinary style without cover.
