a year, yet on a lai>;c plantation a considerably 

 increased number of labourers is required if the 

 system of barking is adopted. No more rubber 

 is obtained, but it is extracted more easily and 

 perhaps in a cleaner condition. On the other 

 hand, the barking injures the tree a little. 



Owners of rubber estates in the Province should 

 either obtain the services of experienced managers 

 from German East Africa or send members of 

 their staf! there to study for three months 

 the routine of management. The conditions of 

 Quelimane will not be altogether those of Tanga ; 

 these will manifest themselves with experience, 

 but the main lines of management can be followed. 



A plantation of Ceara should be protected at 

 intervals of 300 or 400 yards with wind brakes * 

 to protect these brittle trees from the effect of 

 the south and east winds. 



Ceara rubber grows well in the district of 

 Mozambique, but the rainfall is too small for it 

 to become a payable product there. The long 

 dry season reduces the period during which the 

 trees can be profitably tapped to six months or 

 less, a period not long enough for the revenue 

 to be got out of them. The same limitation 

 applies though to a less extent to Inhambane, 

 and I suspect to the territory of the Mozambique 

 * See page 114 (Tobacco).
