Of the soils, Nos. 7 to 13, collected around the mouth of the Kern-booms 

 River, it will be noticed that there is a considerable difference, in the 

 amount of available plant food, between Nos. 8, 10, 12, and 13, on the 

 one hand, and Nos. 7, 9, and 11, en the other. The former axe all either 

 wholly or very largely made up of the alluvial deposits which surround the 

 river mouth ; of the latter, Nos. 7 and 9 were taken from the all-prevailing 

 sandstone formation, and No. 11 from the Enon deposits which flank the 

 alluvium, and with which No. 13 is also probably to a certain extent diluted. 

 The following are the averages of each of these two sets of soils :

The poverty in available plant food constituents, noticed with respect 

 to the southern portion of the George Division, extends, with some reserva- 

 tions, however, into the adjoining Division of Knysna. Here we find on an 

 average even less potash and phosphoric oxide, but the lime shows a slight 

 increase. There is a sufficiency of nitrogen all through, but the inorganic 

 requirements of the soil are lacking in the Zwart River and Gouwkamma 

 Field-Cornetcies. Potash, in fact, may be said to be lacking throughout 

 the Division, with the exception of a limited area round the mouth of the 

 Keurbooms River. Near Plettenberg Bay there is an improvement visible 

 on the farms Ganze Vallei and Witte Drift. Of the two samples collected 

 on the latter farm it will be observed that No. 10 is noticeably the better. 

 The richness of the forest soils near Millwood in nitrogenous material, and 

 organic matter generally, is worth noting, and special attention has al- 

 ready been directed to the quality of the alluvial soil No. 12 from the 

 farm Matjesfontein near the Keurbooms River mouth. There is no doubb 

 that these alluvial, or, as they are locally termed, " vlei " soils, are better 

 supplied with plant nutriment than the average soils of the Division.
