not be accurately estimated. The cutting itself is about 145 feet 

 above sea level, or at the same height as the Bellevue section. 

 Isolated boulders of fossitiferous ironstone can also be traced in 

 the neighbourliood of this cutting for a further height of 15 feet. 

 There is no gravel associated with the ironstone here. From 

 Knight's to Bairnsdale the country falls, and the eocene limestone 

 outcrops on the river banks v^rith pebble drift i-esting immediately 

 upon it. 



In a former paper (6) we traced the northern boundary line 

 of the Gippsland miocene from Red Bluff to the Nicholson River, 

 but the discovery of the ironstone casts at Knight's and Bellevue, 

 as well as of unaltered miocene shells at Rose Hill permits of the 

 continuation of this line for at least eight miles farther west. 

 Between Knight's cutting and the Nicholson the miocene has not 

 been observed, but its existence in portions of the area immedi- 

 ately north of Bairnsdale is not improbable. 



In geographical order going up the river from Bellevue, the 

 section at Drier's comes next, but as in one important respect 

 this resembles Skinner's, it will be described in conjunction with 

 the latter, and we pass on to 



VI. — Boggy Creek. 



On the Government maps this stream is now noted as Prospect 

 Creek, but we retain the old name for the sake of reference to 

 earlier descriptions. It empties into the river through a wide 

 flat. In summer the actual channel is narrow, and confined to 

 the eastern margin of the flat. At the southern end and abutting 

 on the river there is a tine cliff" of eocene limestone 194 feet in 

 height above datum line (sea level), and very steep, a fact which 

 was forcibly impressed on our minds when climbing it on a very 

 hot day. The bank bordering the flat on the eastern side is much 

 lower, rounded, and with a more gradual slope ; it continues for 

 about three quarters of a mile, and encloses a kind of amphi- 

 theatre reaching up to the road. Where the traffic bridge crosses 

 the creek, the flat narrows abruptly, but widens out again on the 

 north. On both .sides of the creek the ascent to the general level 

 of the country is steep ; by actual levelling the highest part of 

 the road, near Dooley's gate on the western slope, was found to 

 be 230 feet above datum line.
