from which the Florida arrow root is made,) having a dam six feet 

 high, with a fall in the tail-race to high water in the river, of not less 

 than 18 inches. There had been a severe drought of five months, 

 and the bed of the everglades was quite dry, with the exception of 

 the brook running over the rapids, which, as far up as I explored it, 

 lay upon the travertine rock, at about eighteen inches below the 

 level bed of the everglades of hard sand, and covered with a strong 

 wiry grass from two to three feet high. This fact of the fall of the 

 waters of the everglades into the Atlantic, has, so far as I can as- 

 certain, hitherto remained unpublished ; nor have I been able to 

 learn that it was known to our officers during the war. Their op- 

 erations were principally on the Gulf side of the Peninsula, where 

 they entered and passed long distances into the everglades without 

 meeting with obstruction to the boat navigation. It appears to me 

 that, considered in connection with the great rapidity of the Grulf 

 6tream in passing through the Straits of Florida, indicating a flow 

 from a higher level, this fall is a very strong link in the chain of 

 evidence which goes to prove that the sea is at a higher level on the 

 Western than on the Eastern coast of the peninsula of Florida.
