present supply. An analysis of the rock taken from the bed

The rock is quite a pure sandstone, with very little calcium 
and magnesium, which accounts in a measure at least for the 
softness of the water. It is a sandstone of the Medina forma- 
tion which at Glenmore borders closely on the Hudson river 
shales.
