 venient process in the bush when water is scarce), 

 or partly checked by using alum after develop- 

 ment, which cannot of course stop any frilling 

 started in the process of development itself. The 

 frilling, which is continued to a limited extent in 

 the washing and fixation of films, can only be 

 dealt with by speeding up these processes as much 

 as possible. The question of the clarity of the 

 water may be met by filtration through cotton 

 wool or linen ; and as regards quantity, consider- 

 able water economy can be effected by using a 

 hyposulphite eliminator, such as permanganate of 

 potassium, which reduces the amount of washing 

 after fixation. 



On the 18th of August, after spending the morn- 

 ing preparing the sable head-skin, while my carriers 

 packed up the camp, we marched south to a new 

 limiting- ground, where I had been assured that 

 the giant sable carried huge heads. This hunters'

 starting. This is typical of Africa ; the truth is

 which flows north-east into a larger one called the 

 Bun go. 



In the evening I hunted the country to the
