clay at thirty feet down. This was also marine but I 

 put it in the Charaplain, also. On Sunday the 11th of 

 August, 1895, I went for an outing down to Rockaway 

 Beach, Long Island, N. Y. I had several things in view 

 when doing so. Of course I wanted to get away from 

 the heat of the city and visit the sea beach. The wild 

 rush of water on the beach had a marked reason to draw 

 me. But more powerful than any other, the desire to 

 .search for natural phenomena was uppermost in my mind. 

 I knew we would go by rail through the country to the 

 beach, tlirough the marine of the ice period and perhaps 

 we would search the soil beneath the sand for "Infusorial 

 earth." We sped along seeing a kettle-hole by the 

 Lutheran cemetery that contained BacillariacesB but we 

 did not stop then to gather the clay there. As we ap- 

 proached the station known as Brooklyn Hills we cut 

 through high hills which I saw then and afterwards 

 made up of moraine, steep, mostly gravel with a white 

 clay of about three feet thickness on top. This clay I 

 recognized as belonging to the iceberg period the same as 

 we had in New Jersey and on Manhattan Island and which 

 makes the bottom of the glacial clay, Lacustrine sedimen- 

 tary deposits of Diatomacese. In this moraine I after- 

 wards got a small, distinctly striated, boulder and near the 

 bottom of the hill. About twelve feet from the bottom 

 was a grey clay with Hematite nodules in it, Cretaceous 

 clay no doubt. Then the country became flat without 

 a hill at all, and sloping gradually down to the salt water 

 which came into the station known as Aqueduct. Cre- 

 taceous clay underlies the country here doubtless, but 

 covered up by glacial moraine. At Aqueduct the railroad 

 runs out on tressels to Rockaway, which is a sandy 

 promentory pointing to the South and makes one of the 

 islands or promontories which line the coast from Cape 

 Cod, Mass., to Florida. They are known in Florida as
