opeu forest-laiid, extending to the Aeiy banks of the Adelaide 

 River. The forests are mainly composed of various sorts of 

 Eucahjptus, and are denser than any seen elsewhere in Arnhem 

 Land. Numerous small watercourses intersect the plains, and 

 are surrounded by jungles of bamboo-caue, large trees of Ficus, 

 and, finally, a species of palm closely allied to Areca. 



In the next district, Bahf Miver, one again meets with the same 

 forest-laud, and, on the whole, the same land of trees; but the 

 forests are more open, chajiging here and there into large plains, 

 which in some places are covered with swamps and lagoons, 

 surrounded by Melaleuca-irees, and in others assume a sandy 

 desert-like appearance. Hermit -Hill lies a little to the southward 

 of Daly Eiver, and on the whole possesses the same natural 

 features. 



About 100 miles inland from the mouth of the Daly Eiver the 

 country consists of broken tableland ; Mt. Shoiubridge lies to the 

 eastward of this and is of considerable height. 



Glencoe (or Fountain Head) has low woods and large open 

 plains. 



Manj Eiver, \^'hich flows to the northward, rises partly in a 

 peculiar granite formation, which extends up to the railway at 

 Union Town, and partly from permanent springs in the great 

 central tableland, Avhence Alligator Elver also flows northward, 

 and whence Katlierine Eiver flows towards the south and west, 

 subsequently joining the Daly Eiver, and bounding Arnhem Land 

 in the south. The great tableland is covered with large forests 

 and permanent water-springs. 



In the neighbourhood of Victoria Eiver the district consists of 

 broken sandstone ranges, covered with Spinifex grass and gum- 

 trees. 



Eoehucic Bay, North-west Australia (18° S. lat.), is desert-like 

 counti'y, covered with scrub and lakes.
