Albert V. James: 



In the three editions of quarter-sheet 7 S.E., u large heart- 

 shaped area of tree covered granite, south of Bulla, is wrcjnglv 

 coloured as basaltic. 



In the military contour map of Sunbury two errors in road 

 marking occur. In the extreme N.E. of the area the formed road 

 L M (Plate XXXII.) is omitted, while the road N in the centre 

 west is shown as continuous across the gorge, which is called in this 

 paper, " Column Gully." 



The granodiorite boundaries in the N.E. cannot be accurately 

 placed, owing to the gravitation of granitic detritus from the hills. 

 It covers the lower lying basalt, and hides the junction. 



Owing to the great accumulation of hill wash along the streams 

 many outcrops are completely covered. Tliis is probably the 

 reason why two conglomerates marked on quarter sheet 7 S.E. are 

 not now visible. 



Attention is drawn to the names of the streams in this area, 

 and a study of the geological quarter-sheets, the military contour 

 maps, and the. parish plans shows how loose the nomenclature has 

 been. The names of the streams in the parish plans of 1901 differ 

 from those of 1916, and as the names of the latter agree with those 

 given by the local residents, the writer has accepted them for 

 this paper. The eastern branch is Deep Creek, the western branch 

 Jackson's Creek, and the Maribyrnong River (formerly Salt- 

 water River), the stream from .the junction of the creeks to the 

 Yarra. The following is a table of the names given to the; streams 

 in this area in old and recent publications : —
