 NASHUA MARL
 NAMF, AND ORIGINAL, DESCRIPTION

 The name Nashua marl was proposed by G. C. Matson and F. G. Clapp' who give the following description:
 "During the progress of the field work for this report, collections of fossils were obtained which indicate that Pliocene marls are extensively developed in the valley of the St. Johns River, and a bed of similar marl near Daytona has been referred to the same period. These beds have certain faunal elements which distinguish them from the other Pliocene beds of Florida; and, hence, they are given a distinct name. They are here designated the Nashua marl, from a locality on the St. Johns River, where they are best exposed. Further study may result in uniting all of the marine Pliocene of Florida under a single name; but for the present it appears desirable to avoid hasty correlation by the use of local names for the beds of different localities, especially where conditions governing deposition appear to have been unlike.
 "Stratigraphic Position:-The Nashua marl is thought to rest unconformably upon the Miocene at DeLand; but this opinion lacks confirmation, as the collections from that locality have not been studied in sufficient detail to determine the exact age of the beds. At various localities, the contact between this formation and the overlying Pleistocene sand has been observed and it is everywhere marked by a distinct unconformity. The Pleistocene beds rest upon an undulating surface of the Nashua marl, which is clearly due to erosion, and the contrast
