It will be of interest to know whether spermogonia commonly 

 occur in the genus EndopJiyllam, for I can find no mention i>f their 

 presence in this group of fungi from the literature which 1 have at my 

 disposal, beyond the fact tliat Saccardo mentions spenuogonia in con- 

 nection with Endophjjihnu Sedl (DC), 8w., and T have been unable to 

 obtain other species of this genus for examination t)n this point. 



13.- -THE GROWTH OF THE NATIA^E KACE8 OF CAPE 

 COLONY AND SOME FACTORS AFFECTING IT.

During the latter part of last yeiw I had occasion to \isit and 

 iiKjuire into the health and sanitary circumstances of a number of 

 nati^■e mission stations in the Eastern Province and south and south- 

 western districts of the colony. Some of the stations visited had been 

 established for many years, and there existed reliable records kept by 

 the missionaries of population, births, deaths, emigration and immigra- 

 tion. I returned from tlie tour with the general impression that the 

 majority of these stations were tenanted b};^ a physically degenerating 

 and practically stationary or, in some cases, even dwindling population, 

 with an enormous infantile mortality rate and an appalling prevalence 

 of tuberculosis amongst the adults. During the early part of the present 

 year I made a tour through the native territories and certain of the 

 larger native districts c)f the colony, visiting a number of remotely 

 situated native areas, and found, broadly speaking, a healthy and vigti- 

 I'ous population, with evidences of extraordinary fecundity and rapid 

 increase on every hand. 



This di^ ersity f)f experience natui-ally led me to 'look into the 

 statistical and public health aspects of the matter, and it has occurred 

 to me that its suggestiveness and importance -from sevei'al points of 

 view — might justify me in taking up a little of your time with its 

 consideration on this occasion.
