Coal and Gold Deposits in Xatal. 



1904-5, or in the various Mines Department reports, but I have made 

 use of a few unpublished analyses, giving some in the table, while 

 others, not available for publication, have assisted me in checking 

 the accuracy of my generalisations. I have avoided analyses repre- 

 senting coals known to be locally affected by igneous intrusions. The 

 samples, on which the analyses are based, were so taken that they 

 represent the commercial product of the seams, and not specially 

 picked coal.
