56 COALFIELDS AXD COLLIERIES OP AUSTRALIA. 



Other seams below Stafford's Four-foot-six are known as 

 Bel-gin's, Striped Bacon, Rob Roy, and Doby's seams. They 

 have all been worked to some extent along 1 the western fall 

 of the bed between Bundamba and Blackstone, but the work- 

 ings have been abandoned for some years. Lately two new 

 collieries have been opened up on coals occurring in these beds 

 on their eastern fall towards Six-mile Creek. 



At Bundamba four seams, each from 3 to 4 feet of good 

 coal, have been met with., known as Braeside No. 1, Braeside 

 No. 2, Braeside No. 3, and Braeside No. 4, or hard coal: they 

 are 75, 40, and 140ft. apart respectively. Braeside No. 1 is 

 supposed to be identical with Bergin's seam, in which case the 

 lower ones are, no doubt, the Striped Bacon, Rob Roy, and 

 Doby's seams. 



The Coal Beds at Swanbank and Covjneana. Here there are 

 two seams, Swanbank No. 1, and Swanbank No. 2. The former 

 is considered by Mr. W. E. Cameron, in his second report on 

 this field, to be a continuation of the Four-foot-six seam. It 

 has been worked to a small extent in. the Swanbank Colliery. 

 The latter he looks upon as corresponding to the position of 

 Bergin's seam about Blackstone. This seam has been worked 

 in the Swanbank and Denham collieries. At Perkins' Free- 

 hold there is a seam 5ft. thick, including bands which are no 

 doubt the same as the Striped Bacon and Rhondda seams. 



Coal Seams in the Neighbourhood of Dimnore. This area 

 is bounded by Stafford's Tunnel fault on the S.W., and the 

 Ebbw Vale fault on the N.E. There are three seams. New 

 Churn No. 1, New Chum No. 2, and New Chum No. 3. The 

 bottom coal of the New Chum No.l seam is generally known 

 as the New Chum seam, and is the only one that has been exten- 

 sively worked in this district. It has been worked from a 

 number of vertical shafts in the Whitwood, Dinmore, New 

 Churn and Ebbw Vale mines. The New Chum No. 1 seam is 

 probably identical with the Striped Bacon and Rhondda 

 seams. The section worked shows from 3ft. Sin. to oft. of 

 dean coal, separated by two bands of white stone with coal 

 between. Numerous faults have dislocated the seam, some of 

 them having over 100ft. displacement, which prove a very seri- 

 ous obstacle to the economical working of the coal. 



The New Chum No. 2 seam, with about 5 feet of coal, has 

 been found by boring 74ft. below the New Chum bottom coal. 

 Apparently this has no representative on the Bundamba side. 



The New Chum No. 3 seam is 68ft. below the New Chum 

 No. 2, and corresponds with the Braeside hard coal. 



The old Aberdare seam is also found in this area, about 

 200ft. above the New Chum seam.
