River and Patazvolonga Creek.

■ On the banks of the River within tidal influences, the Man- 
grove {Avicenna officinalis) with its finger-like pneumatophores 
projecting out of the mud when the tide is low, is the most 
striking object and is obviously of service in reducing the danger 
of erosion. The Mangrove extends as far south as Kaimes n^af' 
h'stcourt House. 
A dense growth of Paper-bark 'Pea-trees (Melaleuca- hal- 
m-aturormn), about fifteen feet high, at , one time clothed, , the 
banks of the Port River, as far at least as the Grange, and ex- 
tended as dense thickets a quarter of a mile through along sub- 
sidiary waterways and on the Saltwater Swamps. Such a thicket-,, 
for instance, stretched from the Port River to that portion of thg 
Military Road that extends along the landward side of the 
sandhills between Estcourt House and the Grange. There -are 
still fringes of these trees in places and parts of the thickets 
still remain in places between Glanvilie and the Grange. During 
the last two or three years, with the onset of bad times, the 
greater portion has, however, been cut down for firewood and the 
saltwatdr-swamps left without the protection of these trees. 
Outside the area we are considering, round the North Arm of 
the P(U't River and up to St. Kikla, there are still extensive 
stretches of Mangrove and Tea-tree Swamps. 
Underneath the ’lea-trec, as for instance near the Grange, 
is an abundance of Suaeda maritima, the individual plants vart'- 
ing often in colour, some having a purplish tint. The several 
species of Samphire are also abundant^ Other lower shrubs 
which are common are the pink-flowered Frankenia pauciflora, 
the , white-flowered Samolus repens, the Billy Button {Cotvla 
corovopijolia), and not quite so numerous the herb-like Apium 
aitstrale and Heinichroa pentandra. Where the Tea-trees are 
absent, the salfwater-swamps are clothed with the same tinder- 
tshrubs, the Samphires being the dominant features. The presence 
of Cotula coronopifolia probably indicates a great access of fresh-
