PART FI. 
THE CHAIRMAN (Mr. Holm) said that he would like to have an 
expression of opinion as to whether compulsory dipping was practicable 
or advisable unless it was carried out universally and noted the effect 
which dipping might have upon the immunity of native stock to tick 
borne diseases. 
Mr. VAN DEN ABEELE said it was the difficulty of universal 
application which had suggested to his Government that the matter 
should be brought before the Conference, as it had appeared to them 
useless in certain countries to introduce pure stock unless dipping was 
made universal. 
THE CHAIRMAN (Mr. Holm) stated that in regard to Kenya no 
compulsory dipping existed, either for native or for European stock. 
The Cattle Cleaning Ordinance was passed in 1920, but it was 
recognised that the element of compulsion should not be applied until 
Government could give financial assistance in cases where the farmer 
was unable to erect a dipping tank without aid. 
Mr. VAN DEN ABEELE sald that it was the desire of his 
Government to build dipping tanks at Government expense. 
COLONEL DOHERTY suggested that perhaps what the Belgian 
delegate desired was to establish comparisons between the value of 
dipping applied to Europeans and the native reserves respectively. It 
was quite evident that dipping was useless unless the Government was 
able to control the movement of cattle, as it was possible for 
Huropeans to maintain clean pastures with fencing and dipping while 
infection existed in the neighbouring areas. 
Mr. VAN DEN ABEELE referred to differential legislation in 
respect of the dipping of cattle and Mr. Holm said ‘that it seemed to be 
quite useless to force one class of stock-owners to dip their cattle, and 
not the other and that unless it was made universal to all stock- 
owners, native or European, in the same district good results could not 
be obtained. 
COL. DOHERTY stated that dipping without fencing was very 
unsatisfactory, even when an attempt was made to control East Coast 
fever on a single farm. 
Mr. WORTLEY emphasised the importance of controlling the: 
movement of stock. 
COL. DOHERTY pointed out that in most cases the boundaries 
between permanently infected and non-infected areas were natural 
boundaries and that the incidence of East Coast fever was governed 
by the ability of the tick to maintain itself uninterruptedly; this. 
depended on conditions of moisture and warmth. 
Mr. WORTLEY said that in the southern area of Nyasaland they 
had cleaned up an infected areca and made dipping compulsory. The 
European farmers allowed the natives to use their tanks on payment. 
THE CHAIRMAN (Mr. Holm) stated that in certain native areas 
in South Africa compulsory dipping was laid down. Stock Inspectors 
had been appointed to see that natives brought their stock regularly to. 
the Government dipping tanks, and he had learned that in Natal and 
Transkei this procedure had been very successful. 
The following Conclusion was adopted : — 
That under existing conditions the compulsory dipping of 
cattle by natives is. at present, impracticable over extensive. 
areas.
