As in the case of the Barkly West soils, the majority of the sample* 

 from the Kimberley Division were collected by Dr. E. A. Nobbs from a 

 large extent of country proposed to be irrigated by means of water con- 

 veyed from the Harts River. Three samples were taken on the farm 

 Schoolplaats. No. 1, a tough black alluvial clay, lying on a subsoil of 

 ilt, represents a heavy piece of land situated close to the Vaal, obviously 

 very rich, but unfortunately limited in extent to a narrow strip along 

 the banks of the river. No. 2 represents the eastern side of a wide low- 

 lying bight of land on the same farm : it is a yellow fine-grained sandy 

 soil. The central and western portions of this bight consist of a stiff 

 loamy marl, grey in colour, typified by No. 3. On the farm Waterfall 

 occurs a stretch of some 800 acres of a red gravelly loam, about 145 feet 

 above river-level. The owner of the farm proposes to irrigate this land 

 whereof No. 4 is a sample by pumping up water from the river below. 

 Two samples of fine-grained brown alluvial soil were collected at Warren- 

 ton, No. 5 a garden, and No. 6 a virgin soil : both of these are from time 

 to time enriched by flooding and deposits of silt.

No. 1. proves to be well supplied with every class of plant food, the 

 analytical results thus confirming the opinion previously formed of the soil. 

 The sandy soil No. 2 turns out to be far below No. 1 in chemical composi- 

 tion. The area whereof No. 3 is a type contains lime largely carbonate 

 in abundance, it is well provided with nitrogen, and has a moderate sup- 

 ply of potash and phosphates. The Waterfall gravelly loam, represented 

 by No. 4, lacks nitrogenous constituents, but has a satisfactory amount of 

 potash, and a fair provision of lime and phosphoric oxide. The Warrenton 

 alluvial soils may be described as chemically of medium quality.
