Hollick have been issued during the past month by the United 

 States Geological Survey and by the Maryland Geological Survey. 

 The first * represents the results of about fifteen years of field 

 work and critical examination of material collected by the author 

 and others on Staten Island, Long Island, Block Island, Martha's 

 Vineyard, Nantucket, the Elizabeth Islands and Cape Cod. A 

 large part of this material, including many of the type specimens, 

 is the property of the Garden, and the remainder belongs to either 

 the Staten Island Association of Arts and Sciences, the Long 

 Island Historical Society or the United States National Museum. 

 The work was undertaken at the suggestion of the United States 

 Geological Survey in order to solve, if possible, several perplex- 

 ing problems in the geology of the region by means of the evi- 

 dence afforded by fossil plants, and the results attained in this 

 connection are condensed on p. 29 in a correlation table of the 

 insular and allied formations. The total number of species 

 described is 222, including 31 which are new to science. The 

 ferns and fern-allies number 6, the conifers 27 and the angio- 

 sperms 189. 



In the second of these contributions,! Dr. Hollick has 

 written the part on fossil plants, in which some 40 species are 

 described and figured, including 11 new to science. Under 

 agreement with the Maryland Geological Survey a free set of the 

 specimens upon which this part of the work was based will 

 become the property of the Garden. It is by far the most exten- 

 sive contribution to the palaeobotany of the Pleistocene forma- 

 tions which has been published in America and the material 

 represents a collection which is not duplicated elsewhere in this 

 country. 



The total precipitation at the Garden during the month of De- 

 cember, 1906, was 2.36 inches. The following maximum tem-
