those specimens which are the property of Columbia University, 
by painting a small red “C” on each one. Such specimens as 
belong to the Garden, or which may hereafter come into the 
possession of the Garden, are to be designated in a similar man- 
ner by a yellow « B.” 
Two collections have been added to the Museum since last 
June: the first a collection of Devonian plants from the Pocono 
Mountain, Pennsylvania, by Dr. Britton, the second representing 
the Pleistocene flora of Maryland, by Dr. Hollick. These col- 
lections have not as yet been critically examined or reported upon. 
The collection contains not less than 8,000 specimens, and 
illustrates the succession of plant life on the earth from the most 
remote era at which plants are known to have existed to the 
present time. Its installation at the Garden will give to the 
public an insight into the wonderfully interesting problems in- 
volved in the study of plant evolution, through the remains of 
species long extinct, entombed in the strata of the earth’s crust, 
the function of these plants in the formation of coal, and the rela- 
tions of living species to their ancestors. It has been shown by 
experience that research along these lines is more readily prose- 
cuted in conjunction with botany than with geology. A pre- 
cedent for the presence of a paleobotanical collection at a botan- 
ical garden is found at the famous Jardin des Plantes at Paris, 
where the fossil plants brought together by the noted French 
savant Brogniart are deposited and displayed, although with much 
inferior accommodations than we are able to afford the Newberry 
ction.

REPORT OF DR. J. K. SMALL AND MR. G. V. NASH 
UPON A TRIP TO FLORIDA. 
Dr. N. L. Britton, Director-in-Chtef - 
Sir; We submit herewith a report of our recent collecting 
trip to southern Florida, made for the purpose of securing living 
plants and seeds for the conservatories, and such museum and 
herbarium material as could be incidentally obtained.
