ICE SHEET OVER LONG ISLAND

Geologists Explain Its Configuration by Action of Nature Many Thousands of Years Ago. ■ • According to geologists Long Island affords particularly clear evidence as to the history of the great continental Ice sheet which covered the northern (States many thousand years ago. The (Southern maurfh of this great ice sheet extended to Long Island, it is aaid, and remMflpd there for a long

time, depositing a thick body of intermixed bowlders, sand, and clay as a terminal moraine, which is now the “backbone” of the island. The ice moved southward and brought these materials from the north, dropping them at its melting edge. This peculiar method of deposition developed a very peculiar topography, consisting of an irregular aggregation of hummocks and hollows, which have produced the many beautiful details of configuration that make the higher parts of Long Island so attractive to

lovers of nature. The most notable of these hollows in the morainal ridge is the one holding the picturesque Lake Ronkonkoma, which lies in a depression 50 feet below the surrounding ridges. Several other similar pits are 80 to 85 feet deep, and some of the larger irregular hollows are several miles in length.

By looping the loop six times in an aeroplane Lincoln Beachey made the great scientific discovery that some men are extremely lucky.
