Report of the Honorary Consulting Entomologist for 1884. 329 
may either go in a moderately straight or slanting line through 
the hide, or may take a semicircular curve— that is, go with a 
sweep up from the warble and run a little way under the cuticle, 
where it ends in a distinct cell. From these various circum- 
stances I think we shall find that the maggot hatches just at the 
outside of the hide, and is now making its way down by the 
channel, which I find quite fresh and open. 
We now need observations of when the appearance of the 
warble, at beginning, becomes general through the country ; and 
also that all interested in the subject would try the effect of 
some one or other of the various applications which have been 
found useful in destroying the maggot in the warble, and report 
the results. 
Touching the warble with a small piece of mercurial oint- 
ment, or with tar, mixed as in sheep-salve (or many other 
applications), all appear serviceable to kill the maggot as soon 
as the warble is found to be open, showing the black tip of the 
maggot within. If this is done early in the life of the maggot, 
we save the drag on the system of the cattle from the sores 
lasting till early summer, and likewise much of the injury to 
the hide ; for the small-forming sores will soon heal, whereas the 
large established warble-holes depreciate the value of the hide 
in all the hands through which it passes. 
I beg further to report that inlormation is being sent from 
farmers in many parts of the country, and most careful co-opera- 
tion is being given from Aspatria, likewise from correspondents 
at Wigton, Hereford, and Birmingham, relating to the condition 
of hides. 
The Newcastle Hide Inspection Society is likewise cour- 
teously co-operating, and the Colonial Company has given some 
serviceable information. 1 was also in communication with 
Professor C. V. Ridley, State Entomologist, Washington, U.S.A., 
during his visit to England, and he has furnished some service- 
able information as to prevention of attack. 
I purpose giving the whole of the information with which I 
am being favoured (with as full illustrations as possible of the 
progress of attack) in my next yearly Report, and also in a sepa- 
rate pamphlet for distribution to contributors, and we shall then 
see what points are needed to complete the subject of practical 
and simple methods of prevention. 
Meanwhile, I beg to add that any information sent me by 
those conversant with the subject will be gratefully accepted.
