Coal-Seams of Van Diemens Land. 141 



exactly opposite our shaft, trying for a second seam, and have 

 sunk 110 feet through soft sand stone and dark " clod" or 

 argillaceous schale." This bore is about 50 to 80 yards 

 from the one before mentioned in which the Company had 

 cut the Coal at 134 feet, and about the same distance nearer 

 the river, in fact close on the bank, — the Coal on the oppo- ' 

 site bank being only 18 feet deep. 



Thus a considerable fault must exist, if the information 

 I have received be correct, along the bed of the Don at this 

 point. See Section PI. V., fig. 1. 



I much regret not having received a map of the surveyed 

 and purchased lands on the Don and Mersey, — which I have 

 twice applied for at the Survey Office, Hobart Town, — as 

 I could then have pointed out very nearly the relative position 

 of the different shafts and bores, as well as the ground over 

 which Coal is most likely to be found. 



From a few rough experiments on specimens from the 

 various Coal-seams, I have obtained results which places 

 them in the following order as regards quality : — 



1. Mersey. 



2. Douglas River, 8 -feet seam. 



3. Douglas Eiver, 20-inch seam. 



4. Fingal. 



5. Prosser's Plains.
