This opportunity is taken to put on record a new locality for 

 fossils in the Hudson shales (?) of Orange County. While waiting 

 for a train at Greycourt some search was made in the exposures of 

 blue argillaceous shale along the N. Y., L. E. and W. R. R. for 

 fossils, but without success. However, in a cut on the Lehigh and 

 Hudson River Railroad, about one-fourth mile southw^est of the 

 station, a slightly calcareous layer was found in which fossils were 

 not uncommon. They are more or less distorted by pressure, but 

 the locality is favorable for excavating in search of specimens. 



It appears that fossils have been found at only a few places in 

 the Hudson stage of Orange County. Mather mentions two locali- 

 ties at which "a few specimens of testacea" were found "near the 

 villages of Walden and Sugarloaf in Orange County."^ Suo-arloaf 

 is four miles southwest of Greycourt, on the Lehigh and Hudson 

 River Railway, and Walden is in the northern part of the county. 

 Fossils were collected at these localities by Mr. Nelson H. Darton, 

 in 1885, and he added a third locality, Rock Tavern, ten miles west 

 of Newburgh, and intermediate between the other two places. Mr. 

 Darton enumerates eight species from near Sugarloaf village, two 

 from Rock Tavern, and four from near Walden.^ 



These localities are also mentioned by Mr Darton in a letter 

 entitled " The Taconic Controversy in a Nutshell," published Janu- 

 ary 22, 1886.* The fossils contained in these slates Mr. Darton 

 was inclined to consider as of Trenton age.* 



Professor Cook stated: "No fossils have been found in the rock 

 [Hudson River slate] in this state [New Jersey], though they are 

 abundant in it in some parts of New York "^ 



Mr. Charles D. Walcott, in a paper on " The Value of the term 

 'Hudson River Group' in Geologic Nomenclature," states, under 

 the heading of " Discoveries of Recent Years," that " the discovery 

 of fossils other than graptolites in the dark shales or sandstones of 

 the Hudson River group below Albany has been infrequent. Mr. 

 T. Nelson Dale found a few species at Marlborough, about eight 

 miles south of Poughkeepsie, in 1879, and Mr. Nelson H. Darton 

 found a few Trenton-Hudson species twenty-one miles south of 

 Newburgh [Sugarloaf village], in 1885. On the east side of the 

 Hudson, Mr. Dale discovered, in an argillaceous schist near Yassar

 p. 133, f. n. 130, on Greycourt, wliere Mr. Darton stated that " west of the 

 Oxford limestone to the Blue, or Shawantrimk Mountain, at Oti.sville there is 

 a rolling country underlaid by slates, which have been recently found to be 

 Trenton in age;" also p. 134, f. n. 142, on Craigville, two miles northeast of 

 Greycourt, see the statement that "This series of slates, occupying large 

 areas in Orange County, New York, and extending southward into New .Jer- 

 sey, contains a mixed Hudson River and Trenton limestone fauna, and sliould 

 perhaps be designated Trenton."
