important points connected with them, it was 

 thought desirable to publish at once all the 

 information and experience gained so far, leaving 

 the outstanding problems to be solved by later 

 experience, and then embody the results in a 

 future edition of the book. Meanwhile they place 

 it before the public as the fruit of a ten years' 

 experience in Uganda. 



Their thanks are offered to Professor Dunstan, 

 C.M.G., F.R.S., for his kindness in writing the 

 Introduction, to Mr. G. Massee, F.L.S., for con- 

 tributing the chapter on Diseases, and to Mr. F. 

 Kaye, A.R.C.SC., for the figures of soil analysis. 

 To the publishers, too, they are deeply grateful 

 for valuable personal help given in the prepara- 

 tion of the work. 



The reports of the Botanical, Forestry, and 

 Scientific Department, of the Agricultural Depart- 

 ment, and of the Government Entomologist have 

 been consulted by the authors on a variety of 

 points, and always with advantage.
