              HISTORY OF WAUPACA COUNTY 9
of about two hundred feet above the surrounding country. They are mostly composed of soft sandstone. On the western side of the south hill, the top layers are very thin sandstone. Beneath this sandstone is a shelly, rotten layer. The hill is made up in this way, one layer of stone resting on a layer of another kind until the bottom is reached. Mosquito hill is greatly affected by the weather as the sandstone is easily eroded. Many fossils can be found on this hill if a person searches diligently. On one of these layers, near the top, was found the fossil of a shell greatly resembling that of the clam.
"The great difference between Poppy's rock and Mosquito hill is the difference in their formation.
"Poppy's rock was formed when the earth's crust was very hot. All the country around here, except Poppy's rock, was under water. The soil washed down from the Isle Wisconsin. It is probable that all the country around here was as high, or a little higher than Mosquito hill. When the glaciers came over here they cut their way and so made hills and valleys.
The Ledge
" If a person could get up high enough and look over the country he would see many hills and valleys. Looking south and east from New London he would see two hills. The one east being Mosquito hill, and the one south is known as the Ledge. A person studying geology would probably say at first that these two hills were once all in one continued hill. But a close observer would see that the stone in the hills were much the same. But the stone in the Ledge which should correspond with that in Mosquito hill is a great deal lower. The valley between Mosquito hill and the Ledge may have been caused by the glaciers passing this way, or ,by an upheaval of the earth's surface. The last reason seems to be the more likely. As has been said, one layer in the Ledge is lower than the layer corresponding in Mosquito hill. A person going over Mosquito hill and the Ledge and not taking much notice of the arrangements of the rock would say that they were of the same formation. But on closer observation it will be seen that Mosquito hill is mostly sandstone, with layers of other kinds of rock between the sandstone. In the Ledge the stone at the top is mostly limestone with a little sand mixed in. But as you get nearer the bottom you will find that the limestone has a great deal of sand mixed in with it. In many ways Mosquito hill and the Ledge are the same. They are composed of nearly the same material, although the layers of stone are not on the same level and do not come in the same order as you go down the side.   Mosquito hill is not as old as Poppy's
