_On Winds and Currents, from the Admiralty Physical Atlas._
In the Northern Hemisphere the effect of the veering of the wind on the
barometer is according to the following law:
With East, South-east, and South winds, the barometer falls.
With South-west winds, the barometer ceases to fall and begins to rise.
With West, North-west, and North winds, the barometer rises.
With North-east winds, the barometer ceases to rise and begins to fall.
In the Northern Hemisphere the thermometer rises with East, South-east,
and South winds; with a South-west wind it ceases to rise and begins
to fall; it falls with West, North-west, and North winds; and with a
North-east wind it ceases to fall and begins to rise.
THE CHEMISTRY OF BOG RECLAMATION.
The mode of proceeding for the reclamation of bog-land at Kylemore is
first to remove the excess of water by “the big drain and the secondary
drains,” which must be cut deep enough to go right down to the gravel
below. These are supplemented by the “sheep drains,” or surface-drains,
which are about twenty inches wide at top, and narrow downwards to six
inches at bottom. They run parallel to each other, with a space of
about ten yards between, and cost one penny per six yards.
This first step having been made, the bog is left for two years, during
which it drains, consolidates, and sinks somewhat. If the bog is deep,
the turf, which has now become valuable by consolidation, should be cut.
After this it is left about two years longer, with the drains still
open. Then the drains are cleared and deepened, and a wedge-shaped sod,
too wide to reach the bottom, is rammed in so as to leave below it a
permanent tubular covered drain, which is thus made without the aid of
any tiles or other outside material. The drainage is now completed, and
the surface prepared for the important operation of dressing with lime,
which, as the people expressively say, “boils the bog,” and converts it
into a soil suitable for direct agricultural operations.
