NOTES ON AREA. 
Locality X-4 represents what appears to be a thriving and 
previously unworked bed of shells, extending beneath the 
Burlington bridge at Winona. While shells are fairly common 
at Homer Station, riff-raff on the bottom made their collec- 
tion somewhat difficult. In the vicinity of Govt. Day Mark 
851-a (840-86 elevation) the party planted 150 pigtoes, 
_ (F. undata), and 100 three ridges, (A. peruviana) in hopes 
of ultimately starting a bed there. Fresh water sponges and 
crayfishes of the identification already given were also collect- 
ed at Homer.
