All of these soils, with hardly an exception in any particular, are 

 lacking in the several mineral constituents of plant food.

The first ten samples in the above list were all collected on the 

 days River Estates, from lands intended to be placed under irrigation. 

 No. 11 was taken from the residential plot Stoneleigh at the town of 

 Uitenhage, where it was intended to plant some 50,000 tobacco plants : it 

 proved to be poor in phosphoric oxide. 



The results obtained by the analyses of these eleven soils* are given
