WARBLES. 
benefit of the trouble he has taken. This point is very observable in 
the following notes. 
The various simple applications or measures by which the warble- 
grubs may be killed or removed with little trouble or cost, and much 
benefit to the animals have been mentioned so fully in previous 
Eeports, that there is no reason to give them again in detail. It will 
be seen from the following instances that various different applications 
may be used with success ; but, looking over the reports sent in for 
the two last years, McDougall’s dip or smear appears to be generally 
preferred. 
Where the owner or superintendent can himself direct operations, 
the application of mercurial ointment, ojice, and as a small touch, on 
the black-tipped tail of the maggot, as seen in the open warble, is a 
treatment which thoroughly and rapidly kills the grub, and does no 
harm to the cattle. But where the ointment is put on carelessly, or 
in great quantities, the application is too unsafe to be advised. 
Squeezing out the maggots is a sure cure, and, though somewhat 
unpleasant to the animal, is so popular that there is a chance of it 
being carried out to a useful extent; but, as mentioned in previous 
years, almost any application of a greasy or sticky nature, thick and 
firm enough to remain on the opening of the warble sufficiently long 
to choke the breathing-pores of the maggot within, or, again, of 
anything which will run down into the warble-cells and poison the 
maggot without injuring the animal, will be of use. 
In the following notes I should particularly wish to draw attention 
to the first communication (by Mr. J. A. Smith, of Kise Hall, 
Akenham, near Ipswich) as to the detriment to dairy cattle caused by 
warble-presence, and also to that immediately succeeding by Mr. D. 
Byrd, of Bunbury Heath, Cheshire, relatively to the good effect of 
preventive measures. 
Mr. J. A. Smith, writing from Eise Hall, Akenham, mentioned :— 
“ McHougall’s smear or dip has apparently cured the hots on my 
purchased cows. I noticed that the animals affected seemed irritable 
under the attack, and this caused them to be troublesome to the 
milker. You will easily perceive that this is prejudicial to the milk- 
record, besides leading to a permanent loss, as well as trying the 
temper of the milkman. An inspection of the animals in our cattle 
markets at this season will convince the most superficial observer of 
the loss inflicted by bots on our herds and oxen.” 
Mr. D. Byrd, writing from Bunbury Heath, Tarporley, Cheshire, 
on April 4th, mentioned :—“ We dressed our dairy cows with dry 
sulphur, as I informed you, and they are very free from the warble; 
at the same time there are a few with suspicious lumps, that we shall 
notice to find if they are old sores or the warble in progress.”
