PROGRESS OF INVESTIGATION.

weight given, runs a good deal lower than the Chicago estimate of 
2 dollars to 5 dollars per carcase, that is, 8s. to 20s. of our money. 
Our highest estimate is considered to occur so rarely comparatively, 
that our average loss as calculated above is 6s. 8 d., not quite up to the 
lowest sum noted from Chicago. 
I have entered on the above items of trans-Atlantic investigations 
partly because I believe I may say that it was the widespread progress 
of the work in our country which roused attention to the need of 
investigation over the far wider area infested in the American Continent, 
and also because the returns sent in there, strengthened as they are by 
the U.S.A. Department of Agriculture having turned its attention by 
its own investigations and publications to the importance of the 
subject, corroborate the views of all here who are pushing on the work 
of prevention. 
In the first years of our British investigations, and successively in 
each season, the reports of those personally interested in the welfare of 
their cattle, and in gaining paying returns from them confirmed (until 
now it has become useless to repeat the reports every year) the ease 
with which this unnecessary and wasteful attack could be got under 
with very little trouble and very little expense. 
Next, in 1888 many of our hide- and cattle-dealing firms came 
forward, and placed in my hands reports of losses running as high as 
over £16,000 in one year from’damage to hides; in my ‘Twelfth 
Report on Injurious Insects’ these returns, with the well-known names 
of great firms and companies at Aberdeen, Newcastle-on-Tyne, Glas¬ 
gow, Manchester, Leeds, Liverpool, &c., speak for themselves as to the 
importance of this branch of loss (see abstract, pp. 121, 122). 
Last year, 1889, in obedience to the wish strongly expressed for 
definite information as to the precise nature of the injury caused to the 
carcase of the animal by much Warble-presence, commonly known as 
licked beef or jelly, I did my best, through the kind help given me, to 
ascertain the bearing of this part of the subject. The results are 
given at pages 104-112, and the leaflet on ‘Licked Beef and Jelly,’ 
in which these are embodied shortly, with full illustration, was received 
with so much interest that the first ten thousand were distributed in a 
few weeks. Mr. Edward W. Darby, Secretary of the Butchers’ Asso¬ 
ciation, Leeds, and Mr. W. H. Hill, Vice-President of the Sheffield 
Butchers’ Association, especially aided in the distribution, and I was 
favoured with notifications of approval of the work from leading men in 
the business, and from Butchers’ Associations in various parts of the 
country, and especially (through their Secretaries) from those of Leeds 
and Liverpool. 
Also, copies of the above-mentioned leaflet were by request placed 
in many of our Agricultural and Veterinary Colleges, and, whilst
