The San Carlos GUS A. MULLER, PROPRIETOR POST OFFICE BOX 668 W. N. URMEY SUCCESSOR TO Miami, Fla. 191 Agassiz thinks the sands are due to the mechanical motion and subtraction of the sea water. The Everglades he regards as a sink or a series of sinks into which the sand has been thrown in the form of dunes and then eroded and subsequently by precipitation at the same time carried to a general level. This sand was derived from the outer coral reefs now elevated in Golden Key and southward to Indian Key. In other words, there was a series of keys back of these reefs or Keys just as there were and they were very filled with the growth of the reefs that developed in those shallow waters in the Atlantic orbit. The cross bedding in the orbits is not so general as Agassiz thought. He would also think the orbits formed under water (36) Bort Key on the elevated reefs the head thorns of echini, sponges, sponges and Horseshoe crabs. A good place to see, Indian Key a good place to see the elevated coral reef. Lower Matecumbe and Fort Bay Largo are other good places to see the elevated reefs. The recent and elevated reefs have a width of about nine miles in the region of Boca Chica and the Marquesas. Elliot Key the elevated reef grows or made up of large canchas. Plantation Key has the elevated coral reef is fast ships. The best places for the elevated reefs are Sand Key, Bahia Honda, Indian Key, Key Largo, Lower Matecumbe, Old Rhodes, Elliot, Ragged and Golden Keys (38).
