The inland Sudanese Zone shows a slightly higher fall than the 

 area covered by the same type of vegetation on the coast, the average 

 being 47'45 inches for 75 wet days. The area occupied by the De- 

 ciduous Forest, as would be expected, shows a transition between the 

 Evergreen Forest and inland Sudanese, namely 5178 inches for 108 

 wet days. 



In considering the records for individual months, the heaviest 

 fall is recorded from Half Assinie, which averages 25'82 inches for 15 

 days in June, whilst on the other hand at Navarro in the extreme 

 north no rain is recorded for November, December, January and 

 February. 



Although the greatest fall is recorded in the month of June for all 

 stations except those in the inland Sudanese Zone, the distribution 

 of the rain is greater through the tempcrary abatement in August 

 and the smaller rains in September and October, only declining in 

 November. Thus in the Evergreen Forest the June average is ii'53 

 inches for 16 days, whereas October and November show 6'$y inches 

 for 15 days and 7'64 inches for 15 days respectively. In the inland 

 Sudanese Zone the secondary season in September actually shows a 

 greater fall than the first season in June, whilst the contrary obtains 

 in the coastal Sudanese Zone where the secondary season rains in 

 September and October amount to 3 or 5 inches only. 



From a study of a chart obtained by plotting the number of inches 

 recorded for each station annually against the number of wet days 

 for the same period, it is seen that the stations fall into the same four 

 groups as those under which the country has been considered from the 

 view of the distribution of its forests. The order from zero being, 

 coastal Sudanese, inland Sudanese, Deciduous Forest, and Evergreen 

 Forest areas. An additional interest is provided however, in that 

 stations which are now situated distinctly in the Deciduous Forest, 

 such as Obuasi and Dunkwa, or even on the outskirts of the Deciduous 

 Forest such as Ejura and Kintampo appear within the group containing 

 the whole of the stations of the Evergreen Forest. It is not too much 

 to assume, therefore, that the natural limits of the heavy Evergreen 

 Forest originally included Kintampo and Ejura, and an examination 

 of the floristic composition of the fringing forests around these stations 

 actually supports this assumption. In considering, therefore, any 

 schemes for re-afforesting parts of the country, as undoubtedly such 

 schemes will have to be considered in the future, activities should, in 

 the first instance, be confined to areas whose rainfall records show 

 that the conditions required for the Evergreen Forest obtain, and 

 by the same token, removal of the fire factors will undoubtedly 

 allow any district showing these rainfall records to re-afforest itself 

 naturally.
