1,600 mules are the carrying equivalent to 800 

 camels. These would have to be divided into com- 

 panies of 400 each. Each company to consist of two 

 divisions under a subaltern, each division of two 

 sections under a conductor, viz. :

36,076^. x 4 = 144,304/. against 84,494/., which 

 leaves a balance of 59,810Z. in favour of the camel 

 transport. Now let us take the initial outlay. 800 

 camels at 15/. apiece (a high price) equals 12,000/. 

 1,600 mules at the same price will cost double this, 

 but 201. to 251. each is more likely to be the price, 

 which would mean a greater outlay of from 20,000. to 

 28,000/. ; while the mule equipment would also amount 

 to about three times as much as the camels' (say 4,OOOZ.
