More than 60 of these monkeys were brought in from around 

 Dodoma, Saranda, Kilamatinde, Manyoni, and Kondoa Irangi. Most 

 of them were trapped in the natives' gardens. The ''njadengwa" 

 are inordinately fond of the three principal products of the district — 

 namely, "mtama" (millet), maize, and "mahikwi" (pumpkin). They 

 also like "kundi" (beans), groundnuts, and the green tops of potatoes. 

 Papaw and bananas were occasionally given as a luxury. 



Feeding them, therefore, presented few difficulties; the usual proce- 

 dure was to give them milk at 8 in the morning; the administration 

 of this was a tedious business, as the bowl had to be held while each 

 individual drank; otherwise they scuffled and upset it, though not so 

 invariably as the baboons did. 



At 9 in the morning a plate of boiled rice was put in every cage 

 and at noon a maize cob or "mtama" head was issued to each mon- 

 key to while away the long hours of the afternoon. Water was taken 

 round between 4 and 5 in the afternoon, and then the evening meal, 

 of cooked, ground maize mixed with "kundi" was put into the cages. 



Deaths were rare and such as occurred were attributable to injuries 

 inflicted on the animals by their captors or to fighting among them- 

 selves. They are very pugnacious as a race and one individual will 

 bite a piece clean out of another or half sever a tail. Temperamen- 

 tally, however, they vary as much as human beings and when caught 

 young and kindly treated they prove docile and affectionate, for a 

 time at least. 



One half-grown monkey, purchased at Manyoni, was notorious for 

 attacking everybody as well as his companions, and was only finally 

 reduced to order by being confined with an old male twice his size, to 

 whom he paid every respect. In reality, his attitude was servile in 

 the extreme. To see him sit quietly while the older animal fed was 

 a revelation to those who had known him foremost in grabbing every 

 tidbit and menacing any other monkey who approached. 



One evening when passing the cages I noticed a row of monkeys on 

 a perch. The end one suddenly seized his neighbor and bit him in the 

 shoulder; the latter seized a tail — not that of his aggressor — and gave 

 it a bite. The owner of the tail, with his eyes on me, grabbed at the
