Fuller, M. L., and Veatch, A. C. Results of the resurvey of Long Island, New York: 

 Science, new ser., 18, pp. 729-731. 



Ries, Heinrich. The clays of the United States east of the Mississippi River: U. S. 

 Geol. Survey, Prof. Paper 11, pp. 150-151. 



A summary of the economic value of the clays of Marthas Vineyard. Concludes 

 that the Cretaceous clays are of little value because they occur in highly folded beds. 

 The glacial clays, which warp in burning, are not well adapted to brick making. 



Veatch, A. C. Notes on the geology of Long Island: Science, new ser., 18, pp. 213, 214. 



, . The diversity of the glacial period on Long Island: Jour. Geology, 11, 



pp. 762-776. 



These two papers by Veatch and that prepared by him in conjunction with Fuller 

 bring out the following points: 1, That the Cretaceous deposits of the New England 

 islands generally form the cores of what had been considered morainal ridges; 2, that 

 there are few, if any, Tertiary beds on Long Island; 3, that several separate ice ad- 

 vances, with corresponding interglacial intervals, occurred in Pleistocene time; 4, 

 that the older beds were folded by the action of ice; 5, that the topography of the 

 last interglacial interval can still be recognized, and that the Wisconsin deposits are 



thin. 

 Cushman, J. A. Miocene barnacles from Gay Head, Mass., with notes on Balanus 

 proteus Conrad: Am. Geologist, 34, pp. 293-296. 



Barnacles found in connection with the fossil crabs referred to Balanus concams. 

 Brown, T. C. A new lower Tertiary fauna from Chappaquiddick Island, Marthas 

 Vineyard: Am. Jour. Sci., 4th ser., 20, pp. 229-238. Abstract in Science, new ser., 

 21, pp. 990-991. 



Gives results of a study of the mollusks that Hollick regarded as post-Cretaceous 



and classifies them as Eocene. Describes the species as new and different from the 



fauna of the Atlantic slope. 



Cushman, J. A. Fossil crabs of the Gay Head Miocene : Am. Naturalist, 39, pp. 381-390. 



Notes the occurrence of concretions in the greensand and describes the fossil crabs 



found in these concretions as well as two genera found in other material collected at 



Gay Head. A plate shows a restoration of Archaeophax signifera. 



Clapp, F. G. Evidences of several glacial and interglacial stages in northeastern New 



England: Science, new ser., 24, pp. 499-501. 

 Fuller, M. L. Clays of Cape Cod, Mass. : Bull. U. S. Geol. Survey No. 285, pp. 432-441. 

 Correlates on lithologic grounds the clay deposits of Cape Cod with those of Long 



Island. 



. Glacial stages in southeastern New England and vicinity: Science, new 



ser., 24, pp. 467-469. 



Announces a scheme for the differentiation of the Pleistocene deposits of Long 

 Island and southeastern Massachusetts. Finds eight distinct epochs of deposition, 

 four of which were glacial, and two well-defined long epochs of subaerial erosion. 



Hollick, C. Arthur. The Cretaceous flora of southern New York and New England: 

 U. S. Geol. Survey Mon. 50, 219 pp. 



Reviews the progress of geologic investigation of the Cretaceous deposits of the 

 region, describes and correlates the plant-bearing beds, and gives systematic descrip- 

 tions of the plant remains. Describes 222 species of fossil plants and figures many of 

 them. Assigns part of the flora to the Raritan formation and part to the " Cliffwood 

 formation" [Magothy] of the Cretaceous system of the Atlantic Coastal Plain. 



Veatch, A. C. Outlines of the geology of Long Island: U. S. Geol. Survey Prof. Paper 

 44, pp. 15-52.
