Landing nets round or square, are made of strong silk or best water
twine cord. Those nets having a joint in the centre of the shank, are
most convenient when travelling. It is not advisable to have too deep a
net, as your flies become very often entangled in such a one, and cause
much trouble and loss of time in extricating them; therefore a net that
is sufficiently deep to hold a good fish without admitting a
possibility of escape, is the kind of net you require.
