The proportion of lime in the soil appears to diminish, as one passes 

 from Heidelberg and Breede River, through the Swellendam and Zuurbrak 

 Field Cornet cies in the direction of Robertson, but rises as soon as the 

 latter division is reached. Phosphoric oxide is very deficient through- 

 out. The soils of Northern Swellendam, it will be observed, are almost 

 uniformly well supplied with potash.

Three samples of rather gravelly soil were collected on Mr. F. 

 Baker's farm Doornboom, adjoining Porterville Road Railway Station. 

 No. 1 was taken from stubble land, which was just being ploughed, be- 

 tween the cottage and the railway line; No. 2 was collected from, land 

 already ploughed, and nearer the cottage; No. 3 was from new lands 

 beyond the cottage on the mountain side. 



Geologically the Division of Tulbagh may be said to comprise four 

 parallel strips, alternately of Malmesburv clay slate beds and sandstone 

 ridges, running almost due north and south. * The three samples above 

 mentioned were taken from the slope of the western sandstone moun- 

 tains, just on the border of the Malmesbury formation; they conform, 

 in chemical composition, to the usual poverty of the sanolstone soils, and, 

 as the proportions of fine earth show, are very coarse-grained in texture.

Two samples of soil were taken from the farm of the Imperial Cold 

 Storage Company at Porterville Road. In practically all respects they 

 resemble the neighbouring soils from the farm Doornboom. 



All the remaining samples collected within this division were taken 

 from the tongue of slates between the two sandstone ranges, but the 

 surface soil is, generally speaking, influenced by the latter, and this 

 added to the fact that the soils, even if undiluted in this way, and 

 formed solely by the disintegration of the Malmesbury beds, would pro- 

 bably show results no better than those noticed in the Malmesbury and 

 Cape Divisions leads one to expect all-round poor soils; an expecta- 

 tion which is fully realised by the results of the chemical analysis.
