canal here as elsewhere. The material next following the marl, 
number 2 of the section, includes cross-bedded river-wash sand, 
partially decayed wood and muck, sand stained brown by organic 
matter, and at places fresh-water marl rock. The distinctly cross- 
bedded sands of this stratum are found near the base, and it is 
here chiefly that the decayed wood and muck occur lying in 
stream channels in the shell marl. The brown sand contains in 
places many fresh-water shells, and grades into the fresh-water 
marl which in places includes at the top as much as two feet of 
rather hard rock. Vertebrate and fresh-water invertebrate fos¬ 
sils occur throughout this bed from the cross-bedded sands at the 
found at Vero. Scale, 1 inch equals 300 feet. The location of the human re¬ 
mains in the canal bank is indicated in the sketch by a cross. The margins 
of the broad valley are indicated by the dotted lines, and the swamp growth in 
the valley by the conventional character. The canal follows the stream valley 
while passing under the Florida East Coast Railroad and the public road. The 
modern stream in this valley followed an ill-defined, anastomosing and fre¬ 
quently changing channel.

the first human fossils found at Vero were taken. 
Resting upon this sand and marl bed and in places cutting into 
it is an alluvial deposit consisting chiefly of vegetable material 
intermixed with sand, grading at the top in places as is true also of 
the bed beneath,-into a fresh-water marl. The average aggrading 
of the stream valley by this alluvial material amounts to about
