ported from Bornu and the north as “kolkol” gum, and it may 
possibly be the chief species supplying the “ Falli” gum to Nafada. 
In Yola Province, however, Acacia Senegal is much less abundant 
than in the north, and is usually an inconspicuous shrub, while the 
tree which the natives point to as the chief source of “ Falli” gum 
is the “fara-kaya” (Hausa, “ white-thorn”), more rarely called 
“ bauji” in Hausa, and “alluki” in Fufulde. This is a large acacia 
with a spreading crown of dark foliage, pale seurfy bark, long white 
thorns and balls of white flowers. It is probably Acacia albida. 
Another species of acacia called “karkara” in Hausa (Fufulde 
“ fitarlahi ”), apparently also known in Hausa as “ kumban shafu, 
or “parshin shafu,” also supplies gum which ranks as “ Falli.” 
This is a tall tree with light coloured bark, spikes of white flowers, 
and branches armed with stout thorns. It is abundant in the north, 
and also on the Bornu road from Yola to Song, and is so far 
peculiar in habitat that one frequently finds it in small areas form- 
ing little groves by itself to the exclusion of most other species. 
The gum appears to be of a particularly agreeable quality, as 
native carriers may often be seen sucking either the gum or pieces 
of the bark along with “kanwa” or Bornu salt as a pleasurable 
diversion.
