I notice that Pennant mentions that the lapwing is decoyed into nets
by the twirling of looking glass. I have seen exactly the same thing
myself on the Continent applied to the taking of larks. A cylinder of
wood, inlaid with pieces of looking-glass, is fixed 'between two
uprights, and made to revolve by means of a small crank and wheel, to
which a line is attached. The netsman, retiring to some little
distance, keeps the cylinder in constant motion by pulling the line,
at the same time keeping up a soft whistling noise with his mouth. The
larks flutter over the twirler, and seemingly dazzled, descend on the
ground between the nets which are then pulled over in the usual
manner.
Steel traps are of many shapes and sizes, and are best procured ready
made from a good firm, though I have known a few country blacksmiths
who could turn them out decently. As everyone knows this, the ordinary
"gin," or tooth trap, used for capturing rats or other animals and
birds, no description is, I think necessary, further than to say that
the springs should be highly tempered, and that the teeth should not
be too long. These traps can be set in various places with or without
baits--in the water, on the ground, up a tree, or on a post; but
post-traps proper, which are chiefly useful, when set unbaited, for
catching hawks, are made with an arm and spring at right angles to the
plate, so that they may be fastened to the post which supports them.
In setting these traps great care and skill are necessary; and in
giving directions how to do this properly, I cannot do better than
quote "Stonehenge," who says:
"First lay the trap on the ground, then mark the outline of it,
allowing half an inch clear all round; out away the turf to this
pattern, and in the centre dig a hole deep enough to receive a strong
peg and the chain which fastens the trap to it, which will thus be
entirely concealed; drive in the peg, arrange the chain neatly upon
this and in the channel for the spring, and then set the trap in its
place, temporarily propping up the plate by a piece of twig, which can
finally be withdrawn by a string; take care so to out away the turf
that the jaws are only just below the level of the ground. Having done
this, cut a very thin slice of the turf which was removed to make way
for the trap, leaving little more than the grass itself with a ragged
edge, and lay this gently on the plate, and withdraw the prop. Then
cover the spring in th
