“I send you three warble grubs taken from the backs of dairy 
cows after a slight application of mercurial ointment to the holes in 
the skin. The date of extraction was the 2nd of August.”—E. E.

Loss on Warbled Hides. 
Up to this point the observations have mainly referred to the stage 
of attack in which the maggot is injurious to the hide, and the 
particulars on the annexed table, with which I have been favoured 
by the courtesy of Messrs. Fry and Company, Leather and Hide 
Factors, Moor Street, Birmingham, show the great money loss caused 
by even this one part of the effects of warble attack. 
Particulars of seven weeks' supply of six classes of hides , being the total of 
each class of sound and warbled sold at two markets in Birmingham, 
commencing May 3rd up to and including June 14 th, 1884 , and showing 
the actual loss of each class of warbled hide :—

It will be observed that of the total number of hides (viz., 5185) 
over one-tliird were warbled ; and, looking merely at one line of the 
figures, it shows that out of 1460 hides, ranging from 65 lbs. to 74 lbs. 
weight, 579 were lessened in value at the rate of Id. per pound, or 
5s. lOd. per hide, giving a total loss on these of £168 17s. 6d. 
The above table of particulars does not include the three classes 
known as “heavy” and “ light ” cows’ and bulls’hides, which also 
were warbled, but the numbers of which were not taken, on account of 
Messrs. Fry not being as much interested in these as in the other 
classes. Enough, however, is noted to supply a scale which, if 
applied to the returns of the other hide markets, would give a fair idea 
of the extent of what is in truth the enormous waste which is going 
forward, as there is not the slightest necessity for warble attack being 
permitted to run on unchecked. Further, this depreciation in the 
value of these hides is unmistakable evidence of there having been
