OX WARBLE FLY. 
The amount on calves cannot be fairly averaged, as in one case 
there were 189 Warbles on 6 calves on one farm; but excluding this 
exceptional case, and taking the total at the other farms of 20 calves 
to 26 Warbles, this gives an average of 1 Warble and a fraction to 
each calf. The above result cannot, I think, but be regarded as highly 
satisfactory. 
The larger amount of Warbles on the heifers and calves is pre¬ 
sumably from the greater difficulty of application. In a note from 
one of the lads—Thomas Jones, of Saighton Lane, near Chester—to 
Mr. Bailey, he mentioned—“ The heifers, through not having been 
tied up last year, were very difficult to hold, and therefore they were 
only imperfectly dressed. However, the dressing has taken some 
effect, for upon the backs of the eleven heifers I only found fifteen 
Warbles.” 
The following are some of the communications which have been 
sent me regarding serious injury to the condition of the 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. Gf. E. Phillips, Treriffith, Moylgrove, near Car¬ 
digan, reported without doubt of the serious nature of the attack, and 
I give his precise wording, as I do not know that any would be more 
appropriate to the misery of the feeding of more than two hundred 
maggots on one wretched animal:— 
“ These infernal maggots are something abominable this season. 
I and 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 Yarmontly 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.”
