to be of the same age as that of the Baltic. In speaking of the 

 amber, which was my reason for mentioning Finch's work, he 

 says that the hgnites of tlie Plastic Clay and Sand Formation 

 usually contain it, and among the localities mentioned are 

 Marthas Vineyard, the Delaware Rix'er below Bordentown, N. 

 J., Cape Sable, Md., etc. Some of these localities Finch visited, 

 some he reports on the authority of Troost, Vanuxem, and 

 others. 



In a recent paper * the writer mentioned amber as constituting 

 one of the characteristics of the laminated lignitic beds which 

 mark the transition to the typically marine deposits of Upper Cre- 

 taceous age. These laminated claj-s and sands constitute what 

 is known as the Magoth}' Formation, the name having been sug- 

 gested by the t)'pica] exposures at Cape Sable on the Magothy 

 River in M iryland, the classic American amber locality, first 

 described b}" Troost nearly one hundred }-ears ago (1821) in the 

 third volume of the American Journal of Science. 



It is not intended to attempt an exhaustive enumeration of the 

 older literature, which has already been done t ; it will suffice to 

 point out that scattered through the works of Vanuxem, Morton, 

 and other contemporary writers will be found quite a number of 

 references to the occurrence of amber, most of which seem to 

 have heretofore escaped attention. 



In studying these Cretaceous deposits during the past few years 

 the v/riter has observed amber at a number of points, of which 

 the following maj' be enumerated. In New Jerse)-, amber was 

 found at Cliffwood Bluff on Raritnn Ba}- : at the pits of the Cliff- 

 v/ood Brick Compan^^ on Whale Creels ; in the pits about one- 

 fourth of a mile Vv'est of tlie Long Branch Railroad on Whale 

 Creelc, where there is little lignite associated \n\\\ it ; near Morgan 

 on Cheesequnke Creek", where the amber is very plentiful and the 

 drftps are of considerable size. On the Delaware Ri\er amber is 

 disseminated through the Magothy sands in the vicinity of 

 Kinkora, N. J. 



In Delaware, the sands along the Chesapeake and Delaware
