The largest of the pines are now losing their 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 about a mile and a quarter, widening towards the east to about eighty rods. This ridge, at least towards the eastern end, is composed of three distinct components, the identity of the individual components. ^'^ ERIE <^\" FROM TRACING-OF MAP MADE BY JOHN DE LA CAMP I866 BY THE.

The whole ridge is now covered by a dense forest consisting of black oak, white pine, cottonwood, black cherry, white ash, etc. Between Graveyard Pond (L) and Big Pond (N) there stands a cottonwood five feet and seven inches in diameter, breast high, and, comparing this with the fallen cottonwood one hun- dred and eleven inches in circumference which Moseley found to be about one hundred and fifty years old, the age of this tree may be esti- mated at approximately two hundred and seventy years. From its position and the mode of the formation of the peninsula there can be.
