and 100 pounds Sulphate of Potash per acre. 
In this connection we also quote experiments conducted 
by Prof. Wohltmann in Camaroon, German West Africa. 
says that typical soils of that. district are very good and 
cacao makes excellent growth when properly treated. Trees 
ten to twelve years old show lack of vitality however, 
and frequently plantations are injured by diseases more 
than should be expected under such conditions. ‘The yield 
also diminishes earlier than might be expected from ex-
