WARBLE FLY. 
amateur breeder and keeper of stock, noted as a report of tlie success 
of his treatment in 1889 :—“ I am glad to say that I believe the fly 
has not been anything like so troublesome about here this season as it 
has usually been. I bave never seen my cattle at all distressed by it. 
I may mention that I have employed common salt for the destruction 
of the grub this season with good results. I bought some young 
cattle of very nice quality in the early summer; they were terribly 
infested w'ith grubs. I had their backs damped, and salt well rubbed 
in, and this was repeated about a week later. The result was that 
every grub was destroyed.” 
Yery many other dressings have been duly recorded as found to 
answer; but in looking over the United States returns I do not find 
that there is any dressing or treatment better than ours, unless it 
may be a greater use of salt and water, or brine, for washing the coats 
of the animals. This is an old-fashioned but apparently very good 
preventive measure, which is noted by Mr. Henry Thompson as used 
in the North of England, and the application of it by rubbing it ivell 
on with a wisp of strcnv (as mentioned by one of the U.S.A. reporters) 
would probably be very serviceable in removing eggs; and getting the 
wash thoroughly in amongst the hair, and well down into the minute 
hair-like channels through the hide, at the bottom of which we find 
the maggot in the very earliest stage at which the infestation is easily 
observable. 
In the foregoing pages observations are given of various easy 
methods of destroying the Warble Fly maggot by stifling it in its cell, 
poisoning it, &c.; but there is yet another method which, when 
circumstances allow (such as condition of the hide, and open state of 
warble), is probably the best of all, namely, squeezing out the maggot, 
and thus getting entirely rid of it at once. 
This requires no outlay in mixtures, no trouble in looking them 
up, and careful application of them when needed, but is what may be 
done by any man or boy on the farm, and which commonly (especially 
in the case of the boys) they enjoy doing. Where care is bestowed on 
the subject, squeezing out may usefully follow on killing by smears, &c., 
in the hide, and healing up happen sooner, and also there will be 
proof that the work was thoroughly done. 
During the whole course of our ten years' work we have been kept 
constantly aware of the success of the plan acted on (that is, destroying 
in the maggot form) preventing recurrence of attack. It is obvious 
indeed that if it had not answered, the plan would not have been gone 
on with, and in the preceding pages reports of the success of this have 
been given; but I just add a few below, received in 1889 (taken from 
many others), regarding benefit obtained. 
The following note, with which I was favoured on September 21st
