Correspondence commenced early in the year with Professor F. W. 

 Oliver, F.R.S., which necessitated further investigation and 

 terminated later in the year with a visit from the Professor, even- 

 tually resulting in his report to the Poole Harbour Board (see 

 " Bournemouth Visitors' Directory," November 25, 1916). 



The first work done this year was the examination of the 

 Wareham Channel and Arne shore. 



Taking a boat from Wareham down the Frome to its junction 

 with Wareham Channel one sees Giggers Island about a quarter 

 of a mile away and at much the same distance from the Trent. 

 It lies a little above high water mark and is, in fact, a succession 

 of large and small tufts of grass intersected by small channels 

 of water. Landing here, a careful inventory of the Flora was 

 taken, resulting in two clumps of Spartina being found in the 

 reeds at the south-west end of the island, th : s bringing the 

 advance of the grass to the head of the Channel. Crossing to the 

 shore a quarter of a mile to the south I landed and examined the 

 shore in the direction of Arne, but no trace of the grass could 

 be seen. (The rest of the report of this district is held over till 

 after the war). 



At Arne Bay, between Patchin's and Shipstal Points, the 

 growth of the grass has been enormous, almost meadowing the 

 whole area. A careful examination of the N.W. end of Branksea 

 Island to off Ower shore and thence to Shipstal, round Long and 

 Round Islands to Middlebere Lake and Fitzworth Point, showed 

 that the meadows of grass are still thickening. East of these 

 islands, sweeping away to Gaathorn Point, the rapid growth con- 

 tinues. 



From Poole northwards and in Holes Bay from Hamworthy 

 Bridge the growth continues and, especially in the north-east 

 section of the bay, there is much new growth. Here, in the 

 spring, was noticed an interesting clump showing the old grass 

 of last season interspersed with the new and surrounded by a 

 dwarf band of bright green colour, evidently showing the new 

 addition of the year's growth. Lytchett Bay still shows increase. 

 South of Poole, at Hospital Island, the increase is rapid. Near 

 the Harbour's mouth the same sluggish growth continues. Cross- 

 ing to South Haven, from Bramble Bay to Redhorn Quay, only 

 very slight growth is noticed, while onward to Xewton Bay and 

 Goathorn it is again rapid.
