Dear Mr. Rock; 
We are sending you herewith a ocpy of a letter 
received a short time since from Captain John H. Camp 
kingfisher, Oklahoma, in regard to a supposed leprosy 
cure used in parts of the Congo. We thought you 
might be interested in Captain Camp’s description of 
the tree and the method of using the wood. 
Very truly yours
