ality — t'\er remarkable — and ix-rsuasive ]jo\vers drew a substan- 

 tial en(l(n\ment from !\frs. Jamieson. and the outcome was a new 

 chemical laboratory at the Collej^e. which was opened on the ist 

 June, ]88i. Hahn himself assumino; the title of Jamieson Pro- 

 fessor of Chemistry. Thus satisfied, for the time, as re.gfarded 

 his own re(|uirements. 1 1 aim sou_^ht for wider fields of action. He 

 began uroins^ the erection of physical laboratories, and, accom- 

 panied hv I'rof. C. 1^. T.ewis. to whom the sug'i^estion of the tour 

 was due, xisited Kimherle\- a.id bihannesl)tTr_<j^ for the purpose of 

 sup])lementin|^ the amount the\- had already collected in Caj)etown 

 for the proposed buildin_L;s. At Kimberley they were gratified 

 by the receipt of l,^oo from .Mr. Khodes towards the scheme. 

 At both centres they met with hearty support, and were .back i'li 

 Ca])eto\vn within a fortnight with their task accom])li.'^hed, and 

 the sum of £5,500 secured for the building and equi}>ment of the 

 existing Physics Laboratory of the ."-^oiuh .\frican College. 



B\- this time other fields of acti\ ity had begun to be worked.. 

 Hahn loved to encourage any movement that in his opi'nion tendefl 

 to the advancement of S(~)uth .Africa (it was one of hi> 

 favoiu'ite sayings that there is only one Table Aloimtain in the 

 world, and only one Capetown in South Africa), and the two 

 directions in which he saw openings for such advancement re- 

 lated to mines and to agricultiu'e. He was ever indefatigable in 

 exertion, and for many \ears after his aj)i)ointment as Professor 

 he habitually travelled about the country during vacation time. 

 often witli ninnbers of his studeiUs. the development of the 

 economic resources of the country, especially of agriculture and 

 more particularly of viticulture and tobacco-growing, claiming his 

 chief attention ; students and farmers were alike instructed during 

 these excursions, not onl\- by Prof. Hahn himself, but by mutual 

 intercourse. Thus the agricultural trend of ]3r. HahnVs 

 sympathies began to make itself felt in the country's affairs: he 

 served on more than one Government Commission to enquire 

 into the condition and possible imimnement of colonial viti- 

 cultm-e. and in 1882. when Fliyllo.vcra 7'aslafri.v threatened to 

 destroy the country's \ineyards. he was associated with the late 

 Hon. j. 11. Hofmeyr in ac(|uiring ( Iroot Constantia for the Gov- 

 ernment as a model viticultural farm, and as a nursery for 

 American \ines. when the demided \ineyards might be recon- 

 stituted with suitable cuttings. 



C^n more than one occasion, wlien the necessity arose for 

 obtaining the serxices of an expert to deal with emergencies of the 

 above character, the (it)vernmein appealed to Dr. Hahn for 

 advice, and thus he had a considerable share first in the in- 

 auguration of agricultural instruction at Victoria College, Stellen- 

 bosch, and subse(|uently in the establishment of the Cape Colony 

 -Vgricultural Department. Throughout his life he continued to 

 manifest this keen interest in the agricultural progress of South 

 Africa, and the recent establishment of agricultural faculties at 

 the Pretoria and Stelleubosch Colleges was neither more nor less 

 than Dr. Hahn had advised.
