We have not (as far as I am aware) any estimates as 
yet of the yearly pecuniary damage from this cause, but 
I have a note from one of the West Country hide firms 
of loss in value of warbled hides being from 10s. to 
15s. apiece ; and in the recent discussion on the subject 
at the Eoyal Agricultural Society, Mr. Stratton gave it 
as his opinion that from various causes, including injury 
to health, milk, &c., there was a loss of <£1 per head per 
annum on the cattle of this country through the injuries 
inflicted by this Warble Fly. 
It is not for me to venture to offer an opinion on many 
of the details of treatment advised by those who know 
far more of the points of direct treatment of the cattle 
than I possibly can do ; but this I may say, from my 
own standpoint of entomological research, that if the 
treatment and attention advocated years ago by Mr. 
Liddell, and also shown by Mr. Stratton to be perfectly 
successful, were carried out, the attacks would be at 
once greatly shortened in the period in which they cause 
injury to the animals, lessened in injury to the hides, 
and likewise the absolute number of Flies would be 
greatly diminished. 
The enquiries of the last few months have shown how 
much sound practical knowledge on this subject exists in 
the country, which would be of exceeding use if collected 
and published; likewise how much invaluable common 
sense practical advice has been given as to the importance 
of cattle owners not only fully knowing what to do, but 
also doing what lies in their power to diminish this 
destructive attack ; and I trust I shall not be considered 
to venture beyond my own exact department in mention¬ 
ing that, whilst in obedience to the request of the Eoyal 
Agricultural Society as their entomologist I am endea¬ 
vouring to procure all serviceable information on the 
habits of this destructive cattle fly, I shall feel greatly 
indebted to all who will be so good as to favour me with 
notes bearing practically on the subject for publication 
as a separate report.
