Sedimentary Formations 
the refuse from a shaft near Lumpy Swamp, in The Forest, 
between Orange and Carcoar. Baron Yon Mueller having 
stated in his Report of 29th July, 1874, that we require to learn 
“ what was the nature of their leaves and floral organs” ; in order 
to search for these, 1 made a second journey to The Forest, having 
first explored it in 1872, and found, together with four specimens 
of Ithytidocanjon Wilkin sonii and a number of already described 
species, several leaven embedded in a ligneous clay in the refuse 
of a shaft, together with portions of the branches of some tree or 
trees. The tissue of the leaves was in some cases so thin that it 
peeled off on touching. The collection, which included a few 
other specimens of seeds and seed-vessels given to me by Mr. A. 
Montgomery, who lives in the neighbourhood, J sent on to the 
Baron, who said he'would forward them to Professor Sehimper, 
of Strasbourg, as he himself was unable at the time to undertake 
their examination. In a short time, therefore, we may expect to 
know more about these interesting plants. 
The thickness of the rocks in The Forest and at Lumpy Swamp 
varies somewhat, but an example or two will show the character 
of the country over the gold-leads :—
