 Dilwyn, Leommster. 



" As a preventative from attack we rubbed a quantity of dry 

 sulphur upon tiie back of our dairy cattle, from the shoulder to hip on 

 each side of the spine, and a little on the brisket. We believe the 

 sulphur had the desired effect, as our cattle were quiet in their 

 pastures, while I could see some herds near were much tormented. 

 The dressing was repeated frequently ; the brisket was dressed to keep 

 the Gad Fly away. We used sulphar as being free from smell, and 

 not liable to taint the milk." — David Byrd, Tarporley, Cheshire. 



"For many years I have used a weak solution of McDougall's 

 sheep-dip, and have found it keep my grazing cattle perfectly quiet in 

 the hottest day. We drive the cattle to a corner and keep them 

 jammed close together by the dog, whilst the man sprinkles them with 

 a common garden watering-pot with a rose on the spout. This is 

 done every week if the weather is wet, otherwise about every ten 

 days." — H. Lindsay Carnegie, Kinblethmout, Arbroath, Nov. 13. 



On looking over the preventatives for attack, the sulphur, or 

 sulphur, tar, and train oil, mixtures appear to be most approved ; but 

 the frequent mention that where the warble-maggots had been de- 

 stroyed the herds rested at peace is a matter that calls for careful 

 consideration. I give only a few words on this here, as the subject 

 occurs further on under heading of remedial measures. But in a 

 communication from Mr. Stratton, of The Duffryn, Newport, in 1884, 

 he mentioned: — " . . . Here, where I had all the warbles destroyed, 

 I have observed only one animal running from fly so far, though in 

 other years they have suffered badly enough. This looks like the 

 effect of treatment, and, if so, indicates that the fly does not go far 

 from its birthplace " 



The following observation bears on the same subject : — 



" Regarding the Ox Bot Fly, I may say that I have had none on 

 my farm for at least ten years. My cattle are now never seen, with 

 tails erected, running as fast as their feet can carry them. Purchased 

 animals generally have these warbles in their backs ; these we take 

 good care to take out by making a small opening with a penknife and 

 pressing out the worms. Thus we do not have the Bot Fly, neither 

 does it seem to come from other farms." — John Milne, Mains of 

 Laithers, Turriff, Aberdeenshire. 



A few remarks should jmrhaps here Oe i/iveii on the Ox Gad Flij, 

 Tahanus bovinus, as, although this insect differs in every point as of 

 size, appearance, and habits, in all its stages from the Warble Fly, its 

 attacks cause severe pain, and in neighbourhoods frequented by the
