aQlInaiS teIlu tO DflIlS Out tiiCoC symptoms and make them more noticeable, this method is often taken advantage of as and aid Tn the detection of affected animals. Tn bad cases, one or more of the following may also become mani fest: Emaciation, anemia, weak ness, discharge from the nose and sometimes the eyes, and an un- thrifty pelt.
 In most cases lungworm trouble tends to be chronic and insidious in nature, the symptoms developing gradually and remaining about the same for a few weeks to several months. Except in bad cases the animals seldom show marked dis tresS or loss of appetite.
 Acute cases, or those that develop rapidly and soon terminate in death are occasionally encounter ed In such instances, there gen. erally is evolved either a heavy in- festation picked up within a short time or complicating bacterial Infection.
 LcSiOnS
 Light and moderate infestations usually are associated with no ap- parent gross lesions. Chronic ca tarrhal inflammation of the wind pipe and its branches, together with more or less abundant phlegm- like exudate in the air passages, Is encountered in some moderate and nearly all heavy infestations. It Is this exudate that is responsible for the characteristic Wheeze or rattle so common in lungworm trouble. Chronic bronchial pneumonia is rather common in bad cases of long standing. The inflammation and the symptoms produced by the lungworms may persist for some time after the animal has recovered from infestation.
 Care and Treatment of Pens
 The droppings tmanure) of all foxes should be picked up thor oughly and safely disposed of each day throughout the year. This is essential to help reduce contam- ination of the ground and prevent the pens from becoming a troub- lesome source of worm infestation Pens should be we'll drained. It is advisable to have drainage ditches around every pen so as to prevent the dissemination of lungworm eggs by water flowing from one pen into another Heavily infested foxes or those showing apparent symptoms of lungworm trouble should not be allowed to remain in breeding pens lany longer than is absolutely essen tial Such animals should be promptly removed to isolated quar- !, antine pens, where they will not have opportunity to infest ground that is used by healthy stock. It requires only short time for a heavily infested fox SO to contam- mate a pen that practically all sus- ceptible animals kept in it will like wise become heavily infested with lungworms.
 Once pen becomes a trouble some source of lungworm trouble it is advisable to abandon 1t unti after it is given treatment tha, will remove or destroy the major portion of the infective lungworn eggs. In the light of present know ledge the following appear to bt the most satisfactory methods O.
 treating badly infested pens:
 l. Moving the pen to well-drainee
 virgin soil, preferably sand.
 2. Removing the top three-incl layer of old soil, safely disposin, of it, and then replacing it witt clean sand or fine gravel. If conditions preclude either o these, then heating the groun
 thoroughly with a large torch, boil !. ing water, or steam might be triec In these treatments it is essentia , lthat the ground be heated well f.
