not sufficiently typical in other words, that the soil it represents had un- 

 dergone some artificial improvement whereby it had been rendered chemi- 

 cally richer than the average soil in the vicinity. Nos. 31, 32, and 33 

 were collected at Houw Hoek, from the orchard of the late Mr. Aspinall : 

 the plot of land whence they were taken lies across the road from the house, 

 on the north-west side of the main road to Caledon. Here also, the soil 

 is, as a rule, poor, being derived largely from the sandstone of the Table 

 Mountain series, whereof the Houw Hoek Mountains are built up. 



Sample No. 34 was collected on the farm Zwart Eiver, adjoining the 

 farm Sergeant's River, on the Genadendal road, about ten miles from 

 Genadendal. The soil is poor all round, like the sandy soil No. 4, officially 

 collected on the same farm.
