From testn. 2 we therefore have: 38.65 °/, of coaln.1I averaging 
13.98 °/, of ash. Further, 42.21°/, of coal n. II, averaging 27.70 °/, of 
ash, and 19.44 °/, of shale and sludge averaging 51.38 °/, of ash. The 
pyrites is chiefly contained in the shale. 
Testn. 3 coal marked B(°) 
This was again acase of aconsiderably streaked coal which appa- 
rently would require to be crushed in order to beable to obtain coal at 
(*‘) Bonito bed.
