of the maggot, seen in the opening of the Warble, or should poison it 
by the application oozing down to the bottom of the Warble cell, As 
the maggot lies with the end through which it draws in food down¬ 
wards, whatever of a poisonous nature that runs down mixes with the 
fluid or putrid matter, and is necessarily swallowed by the grub. 
Of the various applications which are reported, and have been 
reported for several years, as serviceable for killing the maggots, it 
appears to me that mercurial ointment is the best adapted to the 
purpose in hand, as it both chokes and poisons the maggots ; but it 
should never be used except as a very small spot placed just on the 
tail of the maggot in the Warble. It should never be used as a smear, 
nor should the touching be repeated except under special circum¬ 
stances, or to (say) two or three Warble holes, and it should only be 
applied by those who can be trusted. Of the other remedies, 
McDougall’s smear has been the most reported as almost unfailing in 
effect, and squeezing out needs no comment. Where the animal can 
bear it, the operator , especially if he is a boy, has such a satisfaction 
in the demonstrably successful operation that this method needs no 
recommendation. The use of Calvert’s carbolic soap, tar, brimstone, 
and various other applications will be found mentioned below, to 
which I will add cart-grease, or bad butter, or lard mixed with sulphur, 
which has been found to be an extremely good application. 
Benefit from destroying Warble-maggots. 
“ I think I told you that the herd as far as they have been reared 
on this farm, where I have prevented the grubs from developing 
into flies, is quite free from Warble.”—March 28th. . . . : “ In 
exterminating the Warbles on purchased cows in June I used the 
‘ Smear,’ also Bowden’s Hippacae, (Indian preparation), and also 
salt and water. The former two were effectual, but the salt and water 
appeared useless and difficult to apply in the holes caused by the 
Warbles. I am now using McDougall’s dressing, as a wash to keep all 
flies off my cows, with good effect.”—J. A. Smith, Hon. Secretary, 
East Suffolk Chamber of Agriculture. 
“ On our own farm we have strictly followed the directions, and 
killed every maggot, and also smeared the backs of the cattle, with 
most beneficial results. In our stock, which formerly used, (as the men 
say) to boil with these maggots, not one is to be found now, but nearly 
every beast we buy has them. —The Hon. Cecil Barker, Eaton 
Estate Office, Eccleston, Cheshire. 
“ This pest, I am very sorry to say, is very prevalent in this 
neighbourhood. I do my best by the application of mercurial oint¬ 
ment to keep them down in my own herd, but as my neighbours do
