Modifies several views expressed in his " Report on the geology of Marthas Vine- 

 yard." A section of Gay Head worked out by J. B. Woodworth shows closely folded 

 beds, from which he infers that similar folding may be found elsewhere in the island. 

 Recognizes two divisions of the oldest strata at Gay Head — a lower one, which may 

 be Cretaceous, and an upper one, which is probably Tertiary (Miocene). Recognizes 

 above these another series, which he places in the late Tertiary. Notes also evidence 

 of pre-Wisconsin glaciation.

 yard: Am. Naturalist, 24, pp. 562-564. 



Points out that the presence of Cretaceous leaves does not exclude the possibility 

 of the presence of some Tertiary beds. 

 White, C. D. On Cretaceous plants from Marthas Vineyard: Am. Jour. Sci., 3d ser., 

 39, pp. 93-101. Abstract, with discussion by J. S. Newberry, L. F. Ward, and F. J. 

 Merrill, in Bull. Geol. Soc. America, 1, pp. 554-556. 



Corrects the current supposition that the older beds are all of Tertiary age. A 

 study of the flora indicates that the age is " decidedly Cretaceous, probably middle 

 Cretaceous."

 Geodetic Survey Rept. for 1889, appendix 14, pp. 459-460. 



Describes changes in the shore line at the east end of the south shore.

 in North America: Bull. U. S. Geol. Survey No. 82, pp. 86-87, 93-96. 



States that the fossils found by Shaler and White show that Cretaceous deposits 

 exist on Marthas Vineyard. 

 Dall, W. H., and Harris, G. D. Correlation papers: Neocene: Bull. U. S. Geol. 

 Survey No. 84, p. 36. 



Recognizes the presence of Tertiary deposits above the base of the Eocene and 

 below the summit of the Miocene.

. Gay Head: Science, 20, pp. 176-177. 



In these two papers the author applies existing knowledge of the Cretaceous and 

 Tertiary deposits in the Middle Atlantic States to the series of deposits at Gay 

 Head. Believes that the Potomac clay, the Raritan formation, and the Cretaceous 

 greensand marl are represented at Gay Head, and that the structure is not due to 

 mountain building. 



Observations on the Cretaceous at Gay Head: Science, 20, pp. 373-374. 



Restates views expressed in his previous paper.

Does not accept Uhler's correlations of the terranes.
