Clearing must be done on the banks of rivers, lakes, lagoons, at 

 European undertakings, native villages, plantations, washing places, 

 watering places, fords, landing places, bridges, places where native 

 salt is prepared by means of water-plants, and breeding-places of 

 Glossina. The banks must be cleared for a width of 50 metres at 

 high -water level for at least 1,000 metres above and below the point 

 to be protected. Trees more than 5 metres high may be left standing 

 provided that all branches up to 4 metres from the ground are lopped 

 off and that each tree has a clear radius of at least 15 metres around it. 

 If a river is less than 500 metres wide, the opposite bank must be 

 cleared as well, even if uninhabited. The debris from the clearing 

 must be dried and burned. The work of clearing must be done by the 

 occupiers or proprietors of the land, and in default it will be done at 

 their expense by the Government. European undertakings and native 

 villages away from water may be required to carry out clearings 

 within a zone specified by the territorial authorities. 



Fishing on waters registered as fly -infested requires a local permit, 

 which is only given to non-infected persons. Infested waters may not 

 be crossed at prohibited points, and no camping is allowed within 

 500 metres of their banks. 



The limits of infected districts may be surveyed by the authorities 

 and made known by means of posters or public proclamation. Natives 

 living in the districts bordering on the districts of the Lower Welle, 

 Upper Welle, Ituri, and Kivu are forbidden to enter them, but this 

 prohibition may be raised by the Vice-Governor-General of the Eastern 

 Province. Access to other frontier districts may be likewise regulated 

 by the competent authorities. 



New villages, settlements, or halts must be at least 1,000 metres 

 from any water or swamp with uncleared banks. Stables and cattle 

 sheds must be placed at a distance (specified by the medical authorities) 

 from dwellings, and in localities infested with fly, no cattle, pigs, horses, 

 donkeys, or mules may be allowed nearer than 500 metres from a 

 dwelling. 



Wood used as fuel for steamers must be cut at a considerable distance 

 from the banks and must be transported to them after sunset. On 

 .railways, steamers, and other transport systems all places where the 

 presence of staff or passengers is involved must be cleared. Passenger 

 coaches, cattle trucks and other wagons must be screened, and their- 

 doors kept closed. 



The ordinance closes by defining the authorities charged with its 

 administration and with a statement of the penalties incurred by 

 disregard of its provisions.
