114 Coal- Seams of Va7i Diemens Latid, 



cation of it I can suggest is for the manufacture of oil, 

 similar to the oil obtained from rosin and coal, called rosin 

 oil aud paraffin. These oils, now so extensively employed in 

 this country in preparing grease for machinery and for rail- 

 way carriages, are made by cautiously distilling rosin and 

 coal at a heat below that at which they yield gas. I am not 

 prepared to state whether it could be economically applied 

 to this purpose, as it would be necessary to make an experi- 

 ment on a large scale before a trustworthy opinion could 

 be formed. It is, however, in my opinion well worth the 

 trial in the country where this mineral is found. I would 

 also recommend a diligent search for richer specimens of the 

 mineral, and perhaps the resinous substance could be found 

 in a state of greater purity.
