thy wind, as, being
exceedingly dry and hot, it destroys many injurious germs of disease. The
northern brickfielder is almost invariably followed by a strong "southerly
buster," cloudy and cool from the ocean. The two winds are due to the same
cause, viz. a cyclonic system over the Australian Bight. These systems
frequently extend inland as a narrow V-shaped depression (the apex
northward), bringing the winds from the north on their eastern sides and
from the south on their western. Hence as the narrow system passes eastward
the wind suddenly changes from north to south, and the thermometer has been
known to fall fifteen degrees in twenty minutes.
BRICKWORK, in building, the term applied to constructions made of bricks.
The tools and implements employed by the bricklayer are:--the trowel for
spreading the mortar; the plumb-rule to keep the work perpendicular, or in
the case of an inclined or battering wall, to a regular batter, for the
plumb-rule may be made to suit any required inclination; the spirit-level
to keep the work horizontal, often used in conjunction with a straight-edge
in order to test a greater length; and the gauge-rod with the brick-courses
marked on it. The quoins or angles are first built up with the aid of the
gauge-rod, and the intermediate work is kept regular by means of the line
and line pins fixed in the joints. The raker, jointer, pointing rule and
Frenchman are used in pointing joints, the pointing staff being held on a
small board called the hawk. For roughly cutting bricks the large trowel is
used; for neater work such as facings, the bolster and club-hammer; the
cold chisel is for general cutting away, and for chases and holes. When
bricks require to be cut, the work is set out with the square, bevel and
compasses. If the brick to be shaped is a hard one it is placed on a
V-shaped cutting block, an incision made where desired with the tin saw,
and after the bolster and club-hammer have removed the portion of the
brick, the scutch, really a small axe, is used to hack off the rough parts.
For cutting soft bricks, such as rubbers and malms, a frame saw with a
blade of soft iron wire is used, and the face is brought to a true surface
on the rubbing stone, a slab of Yorkshire stone.
In ordinary practice a scaffold is carried up with the walls and made to
rest on them. Having built up as high as he can reach from the ground, the
scaffolder erects a scaffold with standards, ledgers and putlogs to
