158 
NOTE ON WARBLE PREVENTION. 
In the foregoing observations I had not thought it necessary to 
make any further remarks on Warble-infestation, as the subject has 
now been almost yearly recurred to since 1884; and every year 
(including 1896) I have had repeated reports of the success of the 
very simple treatment advised. 
I now, however (February 10th), find that the information is not 
so fully before all concerned as it ought to be, and therefore I insert a 
note of the methods which we find perfectly serviceable, taken from my 
four-page leaflet on Warble Fly (hundred and fortieth thousand), 
which I shall be happy to forward gratuitously to all applicants :— 
‘‘ With regard to methods of remedy, there does not appear to be 
any difficulty of getting rid of the Warble-maggot easily and cheaply, 
when the Warble has ‘ ripened,’—that is, opened so far that the black 
end of the tail is visible. Then it may be destroyed cheaply and 
quickly. 
‘«‘ Squeezing out the maggots is a sure method of getting rid of 
them; but they may be destroyed easily and without risk by dressing 
the Warble with a little of McDougall’s smear or dip, or (without 
noting by name the applications sent out by different manufacturers, 
whether Messrs. McDougall, or the Dee Oil Co., Messrs. Calvert & Co., 
or Messrs. Tomlinson & Hayward, or many others) any grease or 
mixture thick and tenacious enough for a little ‘dab’ of it, when 
placed on the opening of the Warble, to adhere firmly, and thus choke 
the maggot by preventing it drawing in air through the breathing- 
openings at the end of the tail, will answer well. 
‘‘ Cart-grease, if not containing irritating additions, is a cheap and 
handy remedy, and acts well, especially if mixed with sulphur; so 
does lard or rancid butter mixed with a little sulphur, except in very 
hot weather, when it is apt to melt away. Mercurial ointment 
answers, if carefully used,—that is, in very small quantity, and only 
applied once as a small touch on the Warble; but where there is any 
risk of careless application it should not be used. Tar answers if 
carefully placed, so as to be absolutely on the hole into the Warble. 
Bought cattle are often badly infested, and need attention.” —(K. A. O.)
