obtained the extremely rare Antcrosora Fawcetti for which as for 
many of the rarities obtained at various points we were indebted 
to the keen trained eyes of our guide to the Blue Mountain 
region, David E. Watt, who oversees the government garden at 
Cinchona. Raised in the vicinity, a rover in the forest from boy- 
hood and familiar with it, for many years an employee at Cin- 
chona, Watt proved a most valuable assistant to us during our 
two sojourns at Cinchona. Continuing our journey the next 
night was spent at Silver Hill Gap and the following day in ex- 
ploring the almost inaccessible ravines of Doll Wood, where 
many varieties were found, among them Camptodiuin pedatum 
(Desv.) Fee which grows in abundance under the spray of 
waterfalls. The tough thick leaves often become thickly en- 
crusted with a calcareous deposit from the constant spray. 
study of the Piperaceae and collecting material for embryological 
study. We explored anew the regions accessible from that cen- 
ter and made a second and more extended visit to Blue Mountain 
Peak. On this second trip we encountered a most peculiar con- 
dition which, to judge from the usual character of the mountain 
vegetation, cannot be of ordinary occurrence. On the morning 
after our stay —a clear morning which afforded us a most mag- 
nificent view of the country to the north and east of the mountain 
which we had missed on our former visit — the atmosphere was 
intensely dry, so much so that the mosses, ferns and lichens with 
which the trees and rocks are heavily draped were so absolutely 
desiccated that they crumbled to dust as you took hold of them 
and the dust produced by grasping the trees in climbing up or 
down the steep inclines caused excessive irritation of the mucous 
membrane of the throat, affecting all in the party alike. 
The fern flora of the mountain summit is very interesting ; 
Asplenium Harristi, A. Fawcettis,a Dryopteris which has been er- 
roneously referred to D. filiv-mas and a Filix allied to F. fragilis 
which may be the long lost Cystopteris Jamaitciensis Desv. were
