of loss. Many exhausted ones might have recovered with a 
few days’ rest and feeding, and some that were left behind 
as dying, did revive; for this purpose certain stations might 
he made available, although it is admitted that, in marching 
through a wild country, this is sometimes impossible ; with 
a view, however, of resting the overwrought and supplying 
their places with those that had regained their strength, 
depots might be more frequent, and for this purpose all 
transport stations could be utilised. (7.) Proper selections for 
different localities is of great importance. Plain camels did 
pretty well on the way to Candahar as far as Dadur; the 
Bolan Pass was most trying, the Kojuk almost equally so, 
though not so long ; few fatal cases occurred amongst hill 
camels. Colonel McCleod, Commissary of Ordnance, started 
from Sukkur with eight hundred camels and eighty mules; 
he arrived at Candahar with insufficient of the former to 
carry his ammunition (I think less than one hundred and 
fifty) ; seventy-six of the latter accompanied him the whole 
journey. 
Fair summary of camels that might have been saved during 
the South Afghan expedition. —This is a delicate subject, 
which must be left to inference or reasonable speculation. 
We must remember that a proportion of more than one 
third of the seventy dead camels at Quetta were only two 
years old; was there the same leaven of juveniles in all 
the batches which started from Sukkur during the earlier 
months ? How many were killed by want of provision for pro¬ 
per feeding, when arrangements might have been made, had 
some one remembered that the ruminating stomachs require 
special accommodation? How many succumbed to unnecessary 
overdriving ? How many were almost wilfully killed by neg¬ 
ligent Serwans ? How many water stores, everlasting as it 
has amused physiologists to call them, were allowed to run 
dry ? I must repeat that officers’ camels enjoyed a consider¬ 
able immunity from all these evils, and leave my readers 
to speculate, if it please them, as to the numbers that might 
have been saved.
