and the position of the bore-hole the surface is covered with a tough 

 black mud. Proceeding south of the " Station," and a hundred yards 

 from the bore-hole, is a confused heap of argillaceous limestone, ex- 

 tending down the bank of the river for 150 yards ; the layers of this 

 rock vary in thickness from the one-eighth of an inch to a foot, and 

 are frequently separated from each other by seams of fibrous carbonate 

 of lime ; the thickest masses of this rock (weathered) exhibit crack- 

 casts. Two miles lower down the river the sandstone is again visible, 

 presenting the same stratified character as the rock situated 200 yards 

 north of the '* Station." The sandstone in this direction extends to 

 Bagartepett, fifty miles on the road to Warungul, but is not stratified. 

 At the *' Station " the boring carried on in search for coal exhibited 

 the following results. The alluvium is 59 feet deep at the bank of 

 the river ; but it gradually diminishes in depth, and is altogether lost 

 a mile from the river. Beneath this is a layer of blue clay, 1 foot 

 thick. This is succeeded by a bed of argillaceous limestone : this is 

 seen to outcrop in the bed of a nullah about a mile from the river in 

 a S.W. direction ; it is 9 feet 1 inch in thickness, and is occasionally 

 fibrous. Under this is a very thin layer of bituminous shale*, which 

 burns with a yellow flame, emitting a strong odour, and leaving a 

 large residue of white ashes: the thickness of this bed is about three- 

 quarters of an inch. It is superimposed upon a second stratum of 

 limestone, 1 foot thick. Below this we have another layer of shale, 

 4 inches deep ; followed by a layer of impure limestone and blue 

 clay-rock, 8 inches thick, and a bed of bituminous shale 2 feet 

 1 inch. Then a recurrence of impure limestone, 1 foot 9 inches, 

 resting upon sandstone and blue claySf inches in depth; these cover 

 another layer of bituminous shale, 1 foot 1 inch thick, which is 

 separated from another layer, 1 foot 3^ inches thick, by 1 inch of 

 fibrous carbonate of lime. Limestone, 5 feet 3^ inches thick, was 

 next cut through, and found to rest upon black sandy clay, 3 feet 

 in thickness, 6 inches of which were pierced previous to suspend- 

 ing the work. So that we have the following deposits succeeding 

 each other from above downwards : —
