ok WARBLE FLY. 
Besides the letters above quoted, I had communications weighing 
over five pounds with requests for the four-page leaflet, which often 
also conveyed accounts of the suffering, or illness, or inconvenience, 
or consequent money loss, caused by the Warble attack. Frequently, 
also, the application for information was followed after a while by 
another letter, with the mention that reply had been delayed until the 
success of the treatment advised had been proved, and now more of 
the leaflets were desired for circulation in the neighbourhood. 
I do not claim for the treatment that absolutely no Warbles at all 
are to be found where care is taken, but, as will be seen by looking 
over the return (pp. 110—112), the amount of these on the cattle of a 
widespread district may be reduced, with very little trouble and expense, 
to no more in the total than may now be found only too often on a 
couple of beasts where no care has been taken. 
Amongst the many reports which I have received, I am not aware 
of more than three in which the kind of treatment which was applied, 
as being supposed to be what is advised, failed to have good effects, and 
in these cases I do not feel sure that the dressing was well applied. 
Where the maggots are either removed by squeezing, or by choking 
them with external applications (as advised in the leaflet), I am not 
aware of any case in which satisfactory results have not followed. 
Also, so far as reported to myself, the recipe given at page 3 of my 
leaflet for preventing Fly attack in summer answers well; but I think 
it should be carefully kept before the minds of herdsmen, with regard 
to dressings to keep Fly off, that—though the effect of some kinds lasts 
a long time—it is often waste money just to run the animal over with 
some wash of which the effect soon goes off, especially if this is done 
weeks or months before Fly time. 
I know, with absolute certainty, that a little dab of McDougall’s 
Smear properly applied on the tip of the tail of the maggot in each 
Warble-hole will kill the maggot; but I am very far from supposing 
that a dressing of dilute smear or dip,—either of Messrs. McDougall’s 
or of any other firm,—if just only run over the coat in May or June, 
will either choke the maggots then or prevent attack later in the 
summer, when the time comes for the Fly to hatch out of the 
chrysalids. 
The treatment is very simple, but it needs that the material to 
choke the maggot should be applied quite certainly to it, and also that 
the dressing to prevent Fly striking should be of a kind of which the 
effect lasts for a while, and should be applied when Fly is (or is likely 
directly to be) about. • ■ -< 
Train oil (without any addition), applied by being rubbed down the 
spine and a little along the back and ribs, has been found very useful 
as a dressing to cattle when turned out into the fields in summer.- -
