Here there is only one coal seam of merchantable thickness, 
No. 18, and as it comes near the top of the Rio Bonito Beds, it 
appears to be identical with the Barro Branco seam of Santa Catha- 
rina. Thin streaks of coal occur through the series to 123 meters lower, 
or 16.18 meters above the solid granite which was found at 138 
meters below the base of the main S. Jeronymo coal. 
fr. Spalding reports large boulders of granite in No. 54 of the 
section, and this horizon would correspond to the Orleans conglo- 
merate. 
The Rio Bonito Beds have a thickness of 146 meters here, as 
against 53 in the section 18 kilometers distant at Xarqueadas, and 158 
at Minas, Santa Catharina. If the thickness of the Orleans conglo- 
merate be added to the Rio Bonito Beds, at each of the respective 
localities of Minas and in bore hole No. If at S. Jeronymo, there 
results a thickness of 163 and 162 meters respectively for the same 
beds at each locality, a correspondence which must he largely 
accidental.
