AN ENTOMOLOGICAL SURVEY OF KADUNA DISTRICT. 21 



I experienced here, and at most other places, some difficulty in getting blood films. 

 The cattle for the most part belong to Fulanis, who wander about, stopping at one 

 place perhaps one, two, or three months, and then moving on to a fresh part of the 

 country. The Fulanis seemed rather suspicious, and the news of my coming spread 

 rapidly, with the result that I frequently rode miles to see some cattle only to find 

 that they had been taken further into the bush and deliberately hidden. As each 

 cow had to be caught and thrown, the natives naturally disliked the trouble, and it 

 was difficult to obtain many films from any one herd. A further difficulty was later 

 met with in heavy rain, any water on a film spoiling it for minute parasites such as 

 piroplasmata. 



I collected a large number of ticks at Birnawa and at other places to which I 

 subsequently went. 



The New Kaduna. 



After spending a few days examining the neighbourhood of Kaduna, and obtaining 

 -a few films from cattle brought into the town for slaughter, I moved on 6th August 

 to the site of the new capital, some three miles north of Kaduna Bridge. 



Near the village of Kawo, some eight miles from the new site, I found some cattle 

 from which I got a few films. This herd (no. 3) had lived in the neighbourhood for 

 years without any sickness occurring, but one of the four films showed trypanosomes. 

 The country around Kawo consists of fairly open thin bush, well raised above the 

 River Kaduna, and not containing the many small streams that occur in most of the 

 other districts I visited. 



Kakuri. 



On 10th August I went to Kakuri, but I found nothing of interest, except many 

 mosquito larvae in various pools in the bed of the River Remi, about two miles south 

 of Kakuri, all of which proved, on hatching out, to be Stegomyia sugens. 



Near Kakuri itself, and especially close to the River Romi, the kurmi is very dense, 

 and should be suitable for Ghssina to breed freely, should they be introduced. This 

 does not hold good for an area further south-west, between the River Romi and River 

 Kaduna, to which I shall refer later. 



Kudemsa. 



On 13th August I moved out to Kudemsa, a pagan village about twelve miles east 

 of Kaduna Bridge. The country around is of the usual tjqje of low thin bush, but like 

 most of the villages in this district there is a stream close by, with dense kurmi, and the 

 village is more or less surrounded by a wall and a deep ditch, providing an immense 

 breeding-ground for mosquitos after any rain. 



There are no cattle, but a few horses kept here are apparently healthy. 

 Haematopota were numerous by the stream, and CuUcoides were extremely troublesome 

 in the rest-house. 



Bugai. 



On 15th August I went to Bugai, roughly 18 miles north-west of Kaduna Bridge. 

 Hearing that there were some cattle near Kujama, some four or five miles to the 

 south-east of Bugai, I visited this place on the 15th and 16th (herd 4). One sheep
