Dr. Arthur Hollick was occupied during the early part of 

 June in field work, investigating the Cretaceous fossil flora of 

 New Jersey and Martha's Vineyard, in company with Pro- 

 fessor Edward C. Jeffrey, of Harvard University. On June 4 and 

 5 the clay marls and clays in the vicinity of Cliffwood and Mor- 

 gans, N. J., were visited, where they were joined by Mr. Edward 

 W. Berry, of the Maryland and New Jersey Geological Surveys. 

 Valuable palaeobotanical material, consisting of lignites and fossil 

 leaf impressions, was collected, from horizons heretofore only 

 superficially explored and not satisfactorily correlated geologi- 

 cally. It is hoped that the specimens collected may prove to 



determining the exact geological age of the horizons in which 

 they were found. 



After leaving New Jersey and until June 12, Dr. Hollick 

 and Professor Jeffrey were located at Gay Head, Martha's Vine- 



ther collections of fossil plants. This locality is one of the most 



studied and reported upon extensively by geologists, during the 

 past sixty years or more, with varying opinions in regard to 

 the geologic age of the deposits. These deposits consist of 



color of the rainbow, folded and tilted in a fantastic manner by 

 the thrust of the continental ice sheet during the Glacial Epoch, 

 and now exposed in the face of a bold escarpment, about one 

 hundred feet in height. 



It is of interest to note that until the fossil plants found in 

 certain of the strata had been studied and identified as Cretaceous 

 in age any definite or satisfactory data upon which to base con- 

 clusions were lacking. Mr. David White, Dr. Lester F. Ward 

 and Dr. Hollick have all assisted in the work of identifying the 

 fossil plants and the results of their labors on the material from
