collection of tree ferns is, I think, unique in its completeness. 
Plants of the rarer species were collected from various localities, 
and young stages were taken whenever possible as well as 
noticeable variants and forms; so that the results will be summed 
up in an addition of between 4,000 and 5,000 sheets to the col- 
lection. The Cuban ferns, collected jointly with Professor Earle, 
will include at least 600 sheets more. 
The lower cryptogams, particularly the hepatics, will doubtless 
be found to be extensively duplicated, the same species appear- 
ing from several localities; the hepatic collection, however, will 
be found to be fairly representative of the regions visited, at least 
for the more conspicuous forms. Closer collecting will add many 
of the smaller bark-loving species of Frudlania and Lejeunea. 
Not the least important of the results of the expedition was a 
possible solution of the problem of a suitable location for a tropi- 
cal laboratory which has long been under consideration by Ameri- 
can botanists. At the time of the visit of the committee ap- 
pointed some years ago to investigate the subject the plant at 
Cinchona was occupied by the government botanist and was 
consequently out of the question. Now, the exigiences of the 
agricultural development of the island are such as necessitates 
the location of the experimental farm at a lower altitude and the 
buildings at Cinchona are deserted. A one-story six-room house, 
three or four low buildings suitable for laboratory work, with two 
greenhouses of sufficient capacity to conduct experimental work 
under glass could be had of the Jamaica Government at a nom- 
inal rent. Cinchona is nearly a mile above the sea with a delight- 
ful climate (the extremes of temperature for the past twenty years 
being 45° F. and 709° F.), a delightful outlook, and as closely 
accessible to virgin forest as could be obtained. Within three 
miles nearly on a level is Morce’s Gap whose tropical conditions I 
have described above ; close to Morce’s Gap you make this ascent 
to John Crow Peak (6,000 ft.), through a forest of tropical luxuri- 
ance. Below is Mabess River (3,000 ft.) with similar but lower- 
level vegetation. At about the same distance from Cinchona 
(three miles) is New Haven Gap (5,500 ft.) with a similar but 
higher-altitude flora. Still higher altitudes are accessible at Port-
