SOIL FROM MR HARPER, SNAWDON. 



This is a light soil, containing a large quantity of gravel, 

 amounting in the soil to 41* per cent., in the subsoil to 55*. 

 Its colour is very pale, and the gravel it contains consists almost 

 entirely of angular fragments of some kind of schistose rock, 

 the nature of which it is not possible to define more exactly. 

 The subsoil is remarkably similar to the soil, and approaches it 

 very closely in composition.
