laid or rancid butter, mixed with a little sulphur, has 

 also been found to answer. Tar answers if carefully 

 placed, so as to be absolutely on the hole into the 

 Warble. Bought cattle are often badly infested, and 

 need attention. 



To prevent Fly attack in summer, train-oil rubbed 

 along the spine, and a little on the loins and ribs, has 

 been found useful ; so has the following mixture : — 

 4 oz. flowers of sulphur, 1 gill spirits of tar, 1 quart 

 train-oil ; to be mixed well together, and apx)lied once 

 a-week along each side of the spine of the animal. 

 With both the above applications it has been observed 

 that the cattle so dressed were allowed to graze in 

 peace, without being started off at the tearing gallop 

 £0 ruinous to flesh, milk, and, in the case of cows in 

 calf, to produce. 



A mixture of spirit of tar, linseed oil, sulphur, and 

 caibolic acid, has also been found useful ; and any- 

 thing of a tarry nature is useful, as sheep-salve (or 

 bad butter and tar mixed with sulphur), or Stockholm 

 or green tar, rubbed on the top of the cows' backs 

 between the top of the shoulder-blade and loins. 

 Washes of a strong pickling brine, applied two or 

 three times during the season, are very useful. Parafdn 

 and kerosine are useful for a time, but the smell goes 

 off before very long. 



Where cattle are suffering badly from Warbles, so 

 that the health is clearly affected, and the animal 

 wasting, the use of the old well-known " black oils " 

 has been found to do much good. 



Mr. Hy. Thompson, M.E.C.V.S., of Aspatria, Cum- 

 berland, gives the following recipe used for a bad case : 

 — " Turpentine, 1^ oz. ; suli)huric acid, 1 drachm 

 (here a chemical action sets in and must be done with 

 caution). To this I added 10 oz. raw linseed oil, and 

 rubbed the cow's back once a-da}^ with the mixture. 

 ... In a fortnight the back was cleaned, and all the 

 maggots destroyed." 



There are many other points that bear on preven-
