GENERAL ROCK WEATHERING. 
Some brief remarks may be made on this point. The principal 
hard rocks of the district are the granite and the coastal limestone. 
They present a clear contrast, the former being carved into ronnded 
forms, and the latter into serrated ridges and sharp points. 
The effect of the spheroidal ^\■eathering of the granite on a 
great scale as tending to keep the marine-ciit cliffs low, has been 
noticed above. Another point is that these spheroidal coats slip at 
times from higher to lower levels on the land, and so form land- 
slips of which abundant evidence exists at All)any. These land- 
slips cause a danger that must be safeguar<led against as residences 
encroach on to the higher portion of Ml. Clarence. The vegetation 
is of course removed with the rock mass on a landslip, leaving 
a bare and frequejitly steep surface. Rain falling upon this sur- 
face, washes away the soil and debris as fast as formed, and thus 
many of the granite slopes arc destitute of plant life. A striking 
instance of this feature is the bald, smooth mass of granite forming 
the southern end of Mt. Melville. 
The general weathering of the granite is also influenced by the 
numerous basic dykes of two distinct types, by the pegmatite veins, 
and by the very marked variations in texture and composition of 
the granite itself. 
The sharp and serrated mode of weathering of the coastal 
limestone has been already referred to. On the ocean side between 
Skull Head and Cave Point, the limestone has a high dip toward 
the sea. This assists the slipping of the rocks from the cliff face, 
when the latter is undermined by marine abrasion. 
In connection with the weathering of the coastal limestone, 
reference may here he made to the fine examples of casts of roots, 
stems, and branches of shrubs and trees in carbonate of lime dis- 
solved out of the limestone, vide Plate TIL, Figs. 1 and 
2. Apart from its own intrinsic interest, this ])henomenon will 
always possess a great historic value to Australian natural history 
students, by reason of Charles Darwin having very fully described 
it. To that admirable account nothing need be here added. 
OTHER FEAT I RES. 
'I'he Albany district is rich in physiographic interest. Reside 
the phenomena describe<l in this paper, there are possible wave-cut 
terraces, various plains of erosion (indicated by the granite masses 
at various levels) and residuals on such plains. 'Phe writers have 
however, not sufficient evidence to justify at present any account 
of these interesting occurrences. 
SrMMART. 
The Albany district possesses a much indented coast line with 
precipitous cliffs of granite and less frequently of limestone, both
