272 T. S. Hart: 



The head of the I'jlsternwiek Creek is in a hroad open valley 

 north of Cheltenham. On each side of the valley the I'iO ft. con- 

 tour runs in two nearly parallel lines from south-east to north- 

 west, 20 to 30 chains apart. The 110 ft. contouis come in at the 

 two ends of this flat, a mile and a half apart. Most of the flat 

 drains to the Elsternwick Creek, but the south-east end falls to the 

 south-east and the outlet is steeper than the other end. 



The Elsternwick Cieek and its tributaries nowhere cut down to 

 the bed rock; prol)al)ly much of the main valley at least is in" less 

 permeable beds low in the tertiary series. The average fall over 

 4^^ miles from 110 to 10 ft. above sea level is about 22 ft. to the 

 mile. 



A north-westerly trend of the valleys is the rule throughout this 

 area, but the two tributaries from the north bring nearly all the 

 waters down to the south-west side of the system. The more im- 

 portant of these ti-ibutaries receives nearly all its water by north- 

 westerly valleys. The levels along the divides on the north-east 

 and south-east of this system range from 190 to 150. The Moor- 

 abbin ridge, however, only reaches 150 at its highest point, and 

 the actual head of the Elsternwick Creek is below 120.

These are six parallel valleys Avith a north-westerly direction. 

 The first is very straight and regular, starting east of the Point 

 Nepean-road, not far north of Cheltenham, running close to the 

 Moorabbin Ridge, and entering the sea at the foot of North-road, 

 North Brighton. The second heads close to the railway between 

 Highett and Cheltenham, but after running ni.rth-west for a mile 

 and three-quarters, turns south-west into the tliinl valley. .Vnotlier 

 valley starts within half a mile of the angle, and continues ti> 

 the sea on the second valley line. The third extends practically 

 straight from the Kwami)s in Cheltenham Park to .Middle lirighton. 

 The fourth heads a mile west of Cheltenham, but after running 

 north-west to a point nortli of Hampton station, turns south-west 

 into the fifth. On the line of the fourth lower down two other 

 little valleys occur. This series is well seen on the Brighton rail- 

 way, the first just south of (North) Brighton station; the second 

 and third on each side of Middle Brighton. The fourth is here 

 only represented by a very slight hollow. The railway follows tlie 

 fifth from Brighton Beach to Hampton, and the sixth is seen 

 inside the Beach-road lu-low Sandi-inghani.
