its mouth and appears to gasp for breath, sneeze and attempt to swallow. In
the severe cases the appetite is interfered with, mucus accumulates in the
mouth and the bird is dull and listless. The death rate is quite high in
young-chickens and turkeys.

_The treatment_ is both preventive and curative. If the gape-worm is known
to be present in the runs, the ground should be covered with lime, and the
fowls moved to fresh runs if possible. The young birds should not be
exposed to the infection until they are well feathered out. Antiseptics may
be given with the drinking water. Disinfectants should be used freely about
the poultry houses, and the quarters kept clean. The worms may be snared by
inserting a stiff horse hair that has been twisted and forms a loop into
the trachea. This may be dipped into camphorated oil or turpentine. This
treatment should be repeated until the bird has been relieved.
