MOSELEY. 



valley of the Huron and its tributaries therefore afford 

 some species not found nearer Sandusky, but as it is cut 

 through shale, it is not so rich as the valleys farther 

 east. At Berlin Heights, the Old Woman Creek has cut 

 a picturesque ravine through the Waverly sandstone 

 and into the Ohio shale. Here grow several interestmg 

 plants not found farther west. But still deeper ravines 

 have been formed in Florence township by the 

 Vermillion River and its tributaries, the walls mainly 

 of shale, but in the southern part of the township also 

 of sandstone. Here have been found many species of 

 sedges and other plants that do not seem to grow 

 along the Huron or west of it, though most of them 

 grow in the counties to the east where there are still 

 deeper ravines in the sandstone. The walls of these 

 ravines like the walls of a cellar are warmed slowly in 

 summer, so that on the north side of steep, wooded 

 slopes, are some cooler spots than any near Sandusky 

 and hence many plants which are more common farther 

 to the north and east. 



The lake shores and marshes furnish quite a number 

 of species not found in the interior of the state. Cedar 

 Point consists of low sand ridges thrown up by the 

 lake and separating it from Sandusky bay and its 

 marshes for a distance of seven miles. Throughout 

 most of its length the plants are comprised in few 

 species but toward the end it is wider and probably 

 older, having a richer soil and more varied flora. 

 Although more accessible from Sandusky than any 

 other good collecting ground and appearing not to 

 have a great number of species, yet so many rare forms 

 grow there in one place or another that it is not 

 improbable that some plant not on our list at all may 

 yet be found there. Seven years ago, before the work 

 of making a herbarium had been commenced, the 

 writer thought he had found on Cedar Point about all 

 the species that grew there, but each year he has added
