ments of granite and other metamorphic i-ocks, not rounded by the action of waves 

 but in irregular forms, ground, polished, and marked with striae and scratches on all 

 sides. 



On page 489 the following section is presented by Read, and with it a 

 few remai'ks on the drift clays of the Paiuesville moraine, exposed on the 

 bluff of Ashtabula Creek :

The yellow and blue clays are wholly unstratified, composed of the debris of 

 the Erie shales, with numerous fragments of granite rocks. The coarse gravel in the 

 middle of the section is of similar fragments, with the clay washed out of it. The 

 mass bears no resemblance to the shingle of a water-washed beach, the gravel not 

 being polished and rounded into pebbles, but apparentlj' the result of a mass of mud 

 pushed up into a position where drainage has carried off the softer and more liquid 

 materials. The local bed of sand (4 above) is stratified, indicating a temporary' local 

 space of open water apparently soon closed up, and the ice pushing the unstratified 

 claj' above it. This ridge with its mass unstratified and without rounded, water- worn 

 pebbles, can not be the slow accumulations ot a water-washed beach, nor can the 

 materials have been deposited in any waj- which permitted them to fall through water 

 which would sort and stratif}' them. 



In Read's descriptions of the "south ridge" in Lake County, the upper 

 beach line and the moraine are not clearly distinguished. The "south 

 ridge" in Willoughby Township is the Euclid moraine, and in the eastern 

 part of Lake County is the Paiuesville moraine, but what is termed the south 

 ridge at Paiuesville is the Belmore beach. It is remarked concerning the 

 moraine in Willoughby Township that "the southern lake ridge here, and 

 in a large part of the county, is mostly composed of unstratified clays, but 

 is irregular and not well defined." 



Concerning the Belmore beach at Paiuesville, the following remarks and 

 section are presented:^ 



At Paiuesville the south ridge is in places largely composed of coarse, stratified 

 gravel, but it has been modified by subsequent action. The following is a section from
