pile of debris resulting from such washing as shown in figure 40 

 explains why so many fossils have been discovered in this area. 

 Not only were many excellent echinoids, brachiopods and other

 microfossils were obtained simply by shoveling up several boxes of 

 the fine debris.

The last few days of the trip were spent in London where an 

 idea of the stratigraphy of the London Basin was obtained although 

 most of the available time was devoted to a study of Museum 

 methods and to conferences with scientific friends. The material 

 results of the summer's work have reached Washington safely 

 and after two months' work are now unpacked and in proper form 

 for study.
