marsh where, in my opinion, the major creek systems are stable 

 and very, very ancient and established very early in the growth 

 of the thing, and peat is so tough and has such properties that I 

 do not think there's much migration, and the marshes of Georgia 

 and South Carolina. F.or example, oxbow loops cut off in these 

 (southeast United States) marshes very frequently. I have made 

 a tracing of a whole set of airplane photographs and tried to 

 construct a map of Barnstable marsh, and I was only able to 

 find one oxbow loop in the whole thing. The one oxbow loop 

 which I found, 1 decided, was the result of a tributary working 

 backward and finally cutting the loop by accident. I do not think 

 it was a typical oxbow loop. 



Burbanck: In the light of what Dr. Chronic said, is there any possibility 



of making a comparison of some inland marsh like the Great 

 Kankakee with your marine marsh where it is all one way 

 using your grid method in making comparisons. It might be 

 possible to find some areas that were at least comparable. In 

 this way you would have an all one way sort of thing, in the 

 other one you would have both. 



In my squishing through the mud a couple of years ago here 

 (Sapelo Island), I noticed it was quite different from the Cape 

 (Cape Cod) around which I have been collecting. I was im- 

 pressed that there seems to be a very small amount of runoff, 

 whereas around Cape Cod, in practically all cases, there is a 

 large runoff from the land. As Dr. Redfield says, this seems 

 to be a permanently established sort of thing. I am always im- 

 pressed that this runoff has much greater force than the incom- 

 ing tide where it just seems to sort of slowly come up and up. 

 But the other runoff is a very fast, powerful thing, and this 

 picture of erosion that I have seen a little earlier on the slides 

 is something I am finding, particularly this spring, with the 

 very heavy rains that we have been getting. I am actually find- 

 ing erosion up in the heads. I have only worked a little in Maine 

 but the runoff up there seems to be much, much greater than 

 down here too. 



Ragotzkie: I might just add that rainfall is another factor. Erosion of the 



marsh itself by the slumping of the dykes seem^s to occur more 

 under the influence of heavy rains than under the influence of 

 spring tides. Apparently it is the solution effect on the soil 

 matrix. This would be another effect controlling the morphology 

 of the marsh because at some times of year slumping is general 

 along all of the creeks while at other times relatively little 

 slumping will occur. 



Steers: That again is a question of place and climate.
