154 > COLONEL ENGLISH ON COAL- AND [Feb. 1902, 
is an outcrop of augite-syenite forming a large knoll; and 
outside the basin, at Kurujekeui on the north-west, there is a 
considerable outcrop of mica-basalt, with biotite and augite. 
A section of a trial-boring, striking the coal at: 122 feet from the 
surface, is appended ; and I consider that this may be taken as 
a fair sample of the average formation immediately above the coal, 
so far as yet known :—

There are many indistinct leaf-impressions in the sandstone-beds 
above and below the coal, but no other fossils have yet been dis- 
covered in the sandstones, which in this neighbourhood, especially 
below the coal, are very thickly-bedded and free from joints, 
greenish-grey in colour, and form admirable building-stones, 
Some of the cores produced by diamond-drilling have been brought 
to the surface in lengths of 4 or 5 feet, and some of the beds are 
sufficiently tenacious and gritty to be worked for grindstones, 
A boring 225 feet deep, immediately below the coal, yielded the 
following section :—
