XVI WARBLE FLY. 



(not specially largely, but just along the course of the spine), it was 

 found that blood-poisoning was certainly coincident with the sudden 

 death of the animal ; and I have many other notes showing the illness, 

 even up to death, in bad cases of warbles. 



The following observations, forwarded in 188S, are just a few 

 examples of the communications sent me regarding serious injury to 

 the condition of the infested animal, in some cases ending in death, 

 occurring from warble-attack. 



Early in May, Mr. Charles Magniac, of Colworth, near Bedford, 

 wrote me : — 



" Your lecture at the Farmer's Club suggested to me that a 

 young steer I saw lately on my farm was dying of warbles. I have 

 examined him to-day, and have no doubt of it. His back is like a 

 newly-metalled road." On May 8th I received a note from the bailiff 

 (from the Colworth Estate Office) that the animal was dead. 



On June 9th Mr. G. E. Phillips, Treriffith, Moylgrove, near Car- 

 digan, reported without doubt of the serious nature of the attack, and 

 I give his precise n-ordhuj, as I do not know that any would be more 

 appropriate to the misery caused by the feeding of more than two 

 hundred maggots on one wretched animal : — 



"These infernal maggots are something abominable this season, 

 land my man actually squeezed 210 out of the back of a yearling 

 beast, and had to leave many behind ; the poor creature was nothing 

 but a mass of corruption." 



Mr. M. Johnson, writing from Varmontly Hall, Whitfield, Langley- 

 on-Tyne, mentioned : — 



" I live where it is all grazing farms, and the good work has not 

 begun yet. Several of the cattle which were grazed on our highest 

 land did very badly through the winter, and I could only keep them 

 up with very good feeding. These turned out to be totally covered 

 with warbles. Some of the lumps when squeezed out contained 

 nothing but a lot of sticky matter : they have got the turn now, but I 

 firmly believe it was nothing but the warble-attack that was killing 

 them." 



On May 28th Mr. Francis Drawfield, Alton Manor Farm, Wirks- 

 worth, Derbyshire, sent me the following acoount : — 



" In the beginning of April I had a heifer that began to lose flesh 

 (of course she was in calf), and all the good keep and care would not 

 prevent the flesh from going. 



** She went on till the beginning of this month, when she got 

 down and could not get up, but still kept on eating as usual. 



" I had her removed into a warm paddock ; I set a trough in front 

 of her with bran, linseed-cake, and malt, which she continued to eat ; 

 I mashed her malt and put gentian-root into the mash, and she drank
