It will be observed that of the total number of hides 
(viz., 5dS5), over one-third were warbled ; and looking merely 
at one line of the figures, it shows that out of 1,460 hides, 
ranging from 65 to 74 lbs. weight, 579 were lessened in value 
at the rate of id. per lb., or 5s. iod. per hide, giving a total 
loss on these of £16$ 17s. 6d. The above table of particulars 
does not include the classes known as “ heavy ” and “light” 
cows’ and bulls’ hides, which also were warbled, but of which 
the numbers were not taken. 
Mr. C. Haines, Newport, says he seldom saw much of the 
warbles in the pelts, excepting during March, April, and May; 
so it would seem in the early stage of its propagation it 
would not materially affect the hide. He usually commences 
to notice them as April comes in. For about a week he 
judges 50 per cent, to be damaged ; in the next two weeks, 
20 percent.; and for one month additional, say 10 per cent. 
Allowing thus liberally should about cover the year’s damage. 
That done to hides is only a small part of the damage this 
fly causes. What by abortion, watching, galloping, and 
standing in water instead of feeding, less quantity and worse 
quality of milk, and interference in the progress of fat cattle, 
the damage must amount to a very considerable sum. 
The damage is generally greatest on those hides from the 
hottest climates. The hides and skins from Mogador, and 
other northern parts of Africa, suffer most, an average 
perhaps of about one-quarter of them being damaged to the 
extent of 60 per cent, or 70 per cent. Those from Kurrachee 
suffer damage to almost the same extent ; while those from 
Calcutta, Madras, and Bombay are depreciated perhaps to the 
extent of 50 per cent, on 10 per cent, of the skins. From 
Cape Colony the damage is comparatively slight, and still less 
in those hides and skins from Australia and South America.
