The Australasian Scientific Magazine. [Sept, i, 1885. 
The localities where the conditions are most favourable are on the low 
ground forming a narrow band along the western coast of Tiparra, Kilkerran 
and Wauraltee, and a still narrower strip along the eastern coasts of Curra- 
niulka, Muloowurtie and Cunningham, and over most of the area southwards 
leaving out the places where the bed rock out-crops. 
The elevated tertiary beds, viz., those which cover the hign ground and 
occupy valleys between the low ranges should also contain water. Artesian 
water is not likely to be found in them on account of the water-bearing 
drifts, from their elevated position, being continuously subject to drainage. 
It is extremely difficult to give a decided opinion on a question of this 
kind, however, as a bore put down at sea level might tap artesian water, 
while the same water a few yards inland, on the higher ground, would not 
rise to the surface. In boring, therefore, in these tertiary beds, all that can 
be legitimately expected is that water will be tapped when porous beds are 
encountered, and that it will rise to considerable height in the bore, or to 
the surface. 
NOTES ON THE STRUCTURE OF THE 
MATTERHORN. 
BY 
E. WHYMPER. 
When one observes the great peak of the Matterhorn at a short distance, 
it is seen that its rocks are separated into three great divisions, of which 
the middle mass is the largest, and grey in colour, while the upper and 
lower sections are apparently of a dull red. On ascending the mountain, 
these divisions are so clearly apparent, and the junctions of the sections 
are so marked, that it is almost possible to see the lines of separation. The 
rocks on the upper and lower divisions, however, it is found, are by no 
means uniformly red in colour, but are interspersed with others of a green 
and of an iron grey. It is from the red rocks being so much more positive 
in tone that they present a uniform tint when seen at a distance. 
The summit of the Matterhorn is a roughly-lined ridge of 360 feet to 
400 feet in length. It is extremely precipitous on one side ; but on the side
