pleting the results for press which were pubhshed and presented to 

 Parhament in 1896. 



Since then I have superintended the re-reduction of Bailey's 

 Survey to the system of the geodetic survey, and have recently had 

 the satisfaction of issuiug it in an accurate and homogeneous form as 

 a second volume of the Geodetic Survey of South Africa. 



The late Mr. Khodes provided for the Geodetic Survey of Ehodesia, 

 and under my direction a chain of triangles has been carried from 

 Bulawayo to Iron Mine and thence nearly along the 30th meridian 

 to the Zambesi. I am now organising the campaign for extending 

 the work from the Zambesi to Tanganyika, 



During a recent visit to Johannesburg I had the satisfaction of 

 submitting to Lord Milner a plan for the Geodetic and Ordnance 

 Survey of the Transvaal and Orange Eiver Colony. The plan has 

 been approved, and I am happy to state that the man who so 

 successfully carried out the Geodetic Survey of the Cape Colony 

 and Natal — Colonel Morris, E.B., C.B., C.M.G. — has accepted the 

 superintendence of the work. In his hands I feel sure of its 

 success. 



These operations practically will ensure the completion of a chain 

 of triangulation along the 30th meridian from the South of Natal to 

 Tanganyika. It is the dream of my life to see that work carried to 

 the Mediterranean. 



Valuable geodetic work has been done by Mr. Bosnian in British 

 Bechuanaland, and his chain of triangulation there has been con- 

 nected at both its extremities by chains of triangulation with the 

 system of geodetic triangles in the Colony. 



I rejoice to believe that under Captain Jurisch and Mr. Bosman 

 the Secondary triangulation of the Cape Colony is about to be taken 

 up, and thus a sound system laid down for the cartography of the 

 country. 



In the year 1896 I was sent on a mission to Berlin by the Colonial 

 Office to arrange with the German Government for the demarcation 

 of the 20th meridian — the diplomatic boundary between British 

 Bechuanaland and German South West Africa. Plans were sub- 

 mitted by Baron von Danckelmann (the geographical expert attached 

 to the German Foreign Office) and myself. These plans were 

 approved, and l^oth governments placed the scientific direction of the 

 work in my hands. The operation has been in progress since 1898, 

 Major Laffan, E.E., and a German representative are in charge of 

 the field work, which is now nearly completed. The computations 

 are made at the Observatory. 



And now, ladies and gentlemen, I pray you to forgive me for the
