attached and do not live. A study of those algae which are living 

 permanently attached, and I think there are some, would be of 

 considerable interest. 



Moul: In answer to your first question Euglena did not occur in great 



numbers and I am sure there is no pollution out there, but on 

 the mud of Barnstable Harbor Euglena limosa is quite common. 



Redfield: I would not consider those waters polluted. 



Moul: 1 have seen the thing that you are talking about in fresh water 



Euglena where drainage from a house has come down into a 

 gutter and the gutter is just green. When you take this back you 

 have an almost pure culture of Euglena, but we have found limosa 

 on mud ot Barnstable Harbor quite abundantly in June. Mud that 

 came out of Buzzard's Bay at 60 feet (Howard Sanders provided 

 me with this) had Euglena in it, but I was just atraid that there 

 was a pipette lying around somewhere that was contaminated. 

 The second question - Polysiphonia subtilissima is found quite 

 frequently in these pools growing just as you said, right on the 

 stems of the grasses, but 1 think Aghardiella and Gracilaria 

 have come in from the cove but Ectocarpus there was mostly 

 sterile so I do not know the species. Confervoides and another 

 one I cannot think of now are also there, and during June Grinellia 

 is attached. Now whether it grows there or not I have not deter- 

 mined. 



Burbanck: I would like to ask about what part you might find Zostera play- 



ing in its return. Some of the older papers reported this as a 

 pioneer. I was thinking that Ruppia followed right next to the 

 Zostera in transition between the shallow water and on up into 

 the Salicornia. Now that the Zostera is coming back in quite a 

 few places on the Cape, I have seen quite a few, I was just won- 

 dering if this is going to play again a pioneer role in building up 

 marshes. It seems to have played an important role before, and 

 people have mentioned it, but practically no mention has been 

 made of Zostera at all in any of these papers. 



Chapman: Well, I would anticipate that Zostera is going to play the role 



that it formerly did before it disappeared, and it certainly seems 

 to be doing that. It has come back on the marshes in Norfolk in 

 quite substantial quantity although I do not think it is as abundant 

 there yet as it was in say, 193Z-33, but 1 think it will come back 

 and play the same part that it used to unless you get another deci- 

 mation by this bacterial disease. 



Burbanck: As far as the actual gain by accretion, we were very much aware
