THE AMERICAN MUSEUM OF NATURAL HISTORY 



Under the arched entrance way to the Museum, on 77th 

 Street, the visitor first notices a bench-mark established by 

 the U. S. Geological Survey in 1911, indicating the latitude 

 and longitude and the height above sea level (eighty-six 

 feet). On the right is a pot-hole from St. Lawrence 

 County, New York, two feet across and four feet deep. 

 The hole was formed by pebbles whirled in an eddy of a 

 stream beneath the melting ice of the glacier that once 

 covered New York State. To the left is a large slab of 

 fossiliferous limestone from Kelley's Island, in Lake Erie 

 near Sandusky, Ohio, whose surface has been smoothed, 

 grooved and scratched by the stones and sand in the bot- 

 tom of the immense ice sheet that covered this part of our 

 country during the glacial period. Geologists tell us that 

 30,000 to 50,000 years ago this entire section was covered 

 by ice which was moving in a southerly direction. 



Entering the Museum the visitor finds at the left and 

 right the Information Bureau and Visitors' Room. Wheel 

 chairs for children or adults may be obtained here without 

 charge. Postcards, photographs, guide leaflets and the pub- 

 lications of the Museum are on sale, and here one may 

 also arrange to meet friends. A Restaurant is located in 

 the basement.
