 lower limbs and have a maximum diameter, breast high, of nearly 

 twenty inches, thus indicating a probable age of about two hundred 

 and twenty years for this part of the peninsula and correlating it with 

 Ridge No. 4 at Cedar Point. 



Between Cranberry and Long Ponds there is a large ridge (IV), 

 •\vhich, beginning near Jetty No. 2, runs slightly north of east for

 position and the mode of the formation of the peninsula there can be
