syringe is also said to have given good results, but the operation is 

 not as easily performed as one would think at first sight, and often 

 the windpipe is not punctured and the operation is consequently 

 useless. The latest scientific statement in reference to a remedy for 

 lung worm is that injection into the windpipe or, indeed, any other 

 form of treatment, may be looked upon as nearly useless! The 

 embryos of the worm have been found alive in a portion of lung 

 which had been kept for several hours in a strong solution of corrosive 

 sublimate. It is doubted that any drug which could be introduced 

 would kill these worms, even if it killed the sheep. Top dressing of 

 lime and salt, sufficient draining to prevent the formation of marshy 

 spots, is recommended, but probably the best remedy is to remove 

 the sheep to a different pasture. 



Stomach and intestinal worms are usually found in country that 

 is infested with lung worms. The most prominent symptom is 

 scouring, accompanied by loss of appetite and wasting. Abnormal 

 thirst is often shown, and a strong tendency to lick sand or earth. 

 These worms, like those of the lungs, are more severe on lambs than 

 on older sheep. In a worm infested country, when a season favourable 

 to their development occurs, the losses of lambs, or rather weaners, 

 are very heavy. In such seasons the worms are not confined to the 

 rich soil and heavily grassed districts, which are known to be 

 " wormy," but are spread over the soundest and healthiest districts. 

 Such a season occurred about ten years ago in i portion of Victoria, 

 and healthy, lightly grassed plains, on which the sheep never knew 

 disease, were affected, and considerable losses among the weaners 

 occurred. As many of the flocks affected were permanent ones, the 

 sheep of which never left the place till they left it for good, and no 

 fresh sheep were introduced, it rs difficult to account for the rapid spread 

 of the disease. As in the case of the lung worm, veterinarv science has 

 not yet discovered a remedy for this disease. Turpentine has given 

 the hint its action is not to be depended on, though repeated doses 

 are said to have a good effect by killing the young worms. Lysol (a 

 watery solution of tar oil) is regarded as likely to prove the best 

 agent for the destruction of these parasites of the sheep. In the 

 present state of our knowledge, prevention, in the way suggested 

 for lung worms, is about all that can be done, though there are in 

 Australia, in America, and in Britain many so-called cures for the 

 disease. The advice given by those veterinary surgeons who have 

 caret til I y studied the subject, to keep up the strength of the young 

 stock by good feeding and changing them from old, low-lying 

 pastures to newer and higher ones, is, doubtless, the best that can 

 be given. Some years ago, in a neighboring colony, in a district 

 that was badly infected with worms, an experiment was tried 

 by the manager of a large Hock of high-class sheep. On weaning 

 the lambs, instead of putting the young sheep on the pasture, he 

 put them on turnips which he had grown for the purpose. Instead 

 of taking the worm, as was usually the case on that property, the
