42. h'ictfoiifrin. near Haaycnstad. O.I'.S. 

 This saline s])riii<i;- is situated about two miles from the 

 Haa^jenstad salti>an, and a.hout 30 miles north-west-by-north of 

 Bloemfontein. The si)rin!;4-. which has a temperature of 28-30° 

 C. issues from a sand-hill which is capped by a layer of peat 

 formed from the roots of trees, and this overlies a bed of bones 

 and fossil remains. Fossilised bones of extinct types, as well 

 as human im])lements, have been excavated here, some of which 

 have been described by Dr. Broom in the Annals of the South 

 African Museum. In order to offe'- better bathing^ facilities, 

 the owner of the farm has had part of the peat removed, and 

 has erected a primitive bath-house. Through the sand-floor of 

 the bath streams of inflammable gas force their w^ay in liun- 

 dreds of places. This gas, which can only be a decomposition 

 product of the peat, contains about 70 per cent, of marsh 

 gas and 10 per cent, of hydrogen, the remainder being nitrogen. 

 The water and the gas have not been tested for radio-activity. 

 The bath is frequented by hundreds ':^f patients every year, and 

 many wonderful cures are reported Medical opinion holds that 

 the water is particularly efficacious in cases of muscular and 

 i'.rticular rheumatism and sciatica.
