earlier in the season. Castleton Garden is a most delightful 
plantation, containing a fine collection of palms accumulated 
largely by the late George S. Jenman, who was superintendent 
from 1873 to 1879. It was during this period that he made a 
special study of the Jamaica ferns and accumulated the Jamaica 
section of his magnificent fern collection recently secured by the 
Garden. Several days were spent in the vicinity of Castleton 
about the Ugly, Ginger, and Wag Water rivers in order to ex- 
plore particularly the region studied most thoroughly by Jen- 
man. In this way we were enabled to understand more clearly 
Mr. Jenman’s statements regarding the frequency and distribu- 
tion of certain species in his account of the ferns of Jamaica 
since we could thus study the distribution problem from his 
standpoint as well as from our own. For the same reason we 
planned a trip from Castleton to Cinchona extending over a week 
to include other regions studied by him and explore some newer 
territory. We spent four days at Tweedside, for the shelter of 
which we are indebted to the kindness of the owner, Mr. W. B. 
Hannon, of May Penn, and explored the hill region of that now 
overgrown plantation. How far ferns become weeds in that 
region may be seen from the fact that the paths neglected a 
few years only had grown up to various species of Dicranopteris 
(olim Gleichenia) to such an extent as to be impassable except as 
they were beaten down by our guides throwing themselves bod- © 
ily upon them, after which we walked sometimes a fourth of a 
mile or more on the bed of ferns thus made and one to five feet 
above the path on a substratum more unstable than a spring bed. 
Tweedside is adjacent to ‘‘Second Breakfast Spring" 
also one of Mr. Jenman’s favorite resorts. Continuing our itin- 
erary, Moody’s Gap and the lower slopes of Mount Moses were 
explored, and we camped in the road house belonging to the 
commissioner of public works at Hardware Gap on the carriage 
. road from Buff Bay to Kingston. This region would be well 
worth more extensive exploration than we could give it ; mosses, 
hepatics and lichens were in the greatest profusion on the moist 
banks and on the trees and tree ferns. This is the most favor- 
able tree fern region accessible by carriages. In this vicinity we
