plants can also be obtained from American botanical gardens in 
exchange. Meanwhile, gifts of desirable plants will be very

PALEOBOTANY AT THE GARDEN. 
The Columbia University collection of fossil plants, recently de- 
posited with the Garden, under a supplementary agreement between 
the two institutions, dated May 3, 1901, is both interesting his- 
torically and valuable scientifically. It was almost entirely due 
to the labors of the late Dr. John Strong Newberry that the speci- 
mens were gathered together and they represent about forty years 
of active work on his part, largely in the several geological sur- 
veys and exploring expeditions with which he was connected. 
Dr. Newberry was one of the pioneers in paleobotany in this 
country, having read papers on the Carboniferous flora of Ohio 
in 1853, before the American Association for the Advancement 
of Science, and the Cleveland Academy of Natural Sciences. 
These papers, with descriptions and plates of new species, were 
published during the same year in the Annals of Science 
and the Proceedings of the Cleveland Academy of Natural 
Sciences. The type specimens and many others collected while 
Dr. Newberry was at the head of the Geological Survey of Ohio 
are of special interest as representing one of the earliest attempts 
to describe the flora of the Carboniferous Period in America. 
Triassic, Cretaceous and Tertiary plants are represented by 
s exploration of the Missouri 
Explorations of the Grand, Green and Colorado Rivers, in 1859 
and 1861, and by an extensive suite of specimens from the clay 
beds of New Jersey, upon which Dr. Newberry based his “ Flora 
of the Amboy Clays.” An exceedingly interesting series, on 
account of its local character, is that collected by Dr. Arthur 
Hollick during the past decade on Long Island, Block Island 
and Martha’s Vineyard, described and figured in a series of re- 
ports in the Annals and Transactions of the New York Academy 
of Sciences, while the smaller collections represent almost every 
section of the world and every geological horizon.
