The surface of the ground here is about 30 feet above the sea, 
so that the bottom of the bore hole is about 150 feet below it. It 
is probable that the sand forming the lower part of the last 50 feet 
is referable to the New Red Sandstone, met with in the other York 
borings. Water stands 6 feet from the surface, and does not sink 
more than 2 feet.
