Various forms OF traps have been very sue
c~essfully EN- ployed in England and on the Con-
tinent OF Europe as a means of collecting and
constructed that the reaches may easily get into
them and cannot afterward escape. The de.

traps and the methods of using them are here

A simpler form OF trap. which am informed
by Mr.. +. G.. Pratt is very successfully used in
London. England. consists OF any deep vessel
or jar. against which II humber of sticks are
placed and bent over so that they project into
the vessel FOR n few inches. The vessel Is par

which reaches seem TO have Il special fondness.
III the morning these vessels are found charged
with great quantities OF dead and dying reaches
which iay.. climbed up the inclined stuck and
