Causes of Chronic Roaring. 125 



especially were the ammunition-waggon horses affected, and 

 they were quite unable to move their loads, which neces- 

 sitated the horses being taken from the other waggons to 

 assist. The waggons were then dra-wn alternately for about 

 half a mile, the horses returning for the remaining waggons. 

 This excessive exertion was continued throughout a dread- 

 fully hot day, with but little food, and without water for the 

 animals. The laboured and distressed breathing of these 

 horses could be heard a long way off — in fact, it was quite 

 painful to witness their distress. 



"The next morning we marched at two o'clock, but had to 

 leave three horses behind, their breathing being so bad it 

 was impossible to move them ; and two were still Roaring 

 badly, although they had been at rest for about five hours. 

 The road now was somewhat better, but the Roaring of the 

 horses had increased, and there were several fresh cases. 

 After arriving at Kassassin, where we stayed some days, the 

 horses picked up in condition ; but when we marched again, 

 I noticed the Roaring had not disappeared — in fact, many 

 more horses were affected. And after Tel-el-Kebir, on 

 September 13th, and during our march on Cairo, several 

 animals had to be destroyed, as the Roaring brought them 

 to a standstill, while others were left behind at villages in 

 charge of the sheiks, who afterwards brought them to us. 



" On arriving at Cairo, out of the 210 horses embarked, 

 about 185 were with the Battery, including officers' 

 chargers ; of which number 33 were Roarers, 13 ' broken- 

 WLuded,' and several others more or less affected in their 

 breathing (Whistlers). Many of the affected horses after- 

 wards died of fever; some were destroyed from various 

 causes ; others were cast and sold ; and a few were sent to 

 the Mounted Military Police, and are now (1888) serving at 

 Cairo and Alexandria. 



"After I arrived at Cairo (in 1886), I saw many cavalry 

 horses that had become Roarers during the campaign. 



" The immediate cause I attributed to fever, contracted
