148 THE PLANT LIFE OF MARYLAND 



attested by the brown color of the water of the streams (the Chica- 

 comico, Transquaking and Little Blackwater Rivers) which are 

 scarcely clouded even at times of heavy rain. Moreover the areas 

 noted are miles from the outlets of the streams, and several miles 

 from the open tidewater, so that they are doubly protected from the 

 deposition of silt. The evidences of the encroachment of the Marsh 

 are the occurrence of remains of Pinus taeda at considerable distance 

 beyond the present forest and the occurrence of half dead trees well 

 outside the line of the present shore. The Marsh plants, on the 

 other hand, are to be found in the outermost zone of the Pine forest 

 in undiminished abundance and vigor. The evidence of the vegeta- 

 tion was confirmed by learning at one of the localities that a planta- 

 tion (Guinea ISTeck) had existed before the war in a place where 

 there is now only a very small island not already occupied by Marsh 

 vegetation.
