A sample of soil where vines and fruit trees nourish was collected on 

 the farm De Turn, once part of the farm Rietfontein, now commonly 

 known as De Hoek, and adjoining Wittewater. The soil in this neighbour- 

 hood varies considerably, but the sample under notice is typical of the 

 slopes immediately below the mountain; it is of considerable depth, in 

 fact sluits nearly twenty feet deep show no change all the way down. This 

 soil differs from that on the lower levels, such as the Piquetberg Karroo, 

 which, however, outwardly resembles it, but differs from it in being some- 

 what gravelly, containing ironstone pebbles. 



No. 2 is a type of the soil used for the cultivation of tobacco on the- 

 farm Moutons Vlei, one of the tobacco farms of the north-western 

 districts.
