"poor" soil from the same hacienda as numbers 5 and 6, does not betray marked 

 signs of poverty except in its being much coarser, having a sandier texture, only 

 77.5 per cent of its subsoil being fine enough to pass a 1-millimeter sieve. Numbers 

 8 and 9 are two distinct types of soil from the hacienda Carmen, the former, a 

 fairly heavy clay, being considered the better, since the latter, a very sandy loam, 

 though yielding as a rule heavier crops, does not produce as good a quality of 

 sugar. Trusting to chemical analysis alone, number 9 would be considered much 

 superior. The mechanical analyses of these soils show their marked difference, 

 number 8 containing much less sand and more silt and clay than number 9. 



In the case of numbers 10 and 12, stated to be "good" soils, as opposed to 

 numbers 11 and 13, "poorer" fields in the same haciendas, analyses agree very 

 nicely with judgment of these lands, based on the practical experience of the 

 planters, numbers 10 and 12 being markedly richer in every element of fertility, 

 and especially so in potash and lime. Physically they contain more very fine 

 sand and silt, and less clay, than numbers 11 and 13.
