42 THE AMERICAN NATURALIST. 
although several species belong to the island. Of the hetero- 
sporous ferns the only one met with was Marsilia polycarpa. 
Several species of Selaginella and Lycopodium were com- 
mon, and Psilotum triquetrum was encountered once, but is 
evidently rare. 
The liverworts are comparatively scarce at the lower levels, 
but amazingly abundant and varied in the higher altitudes, 
where the ferns also reach their maximum development. 
Algze were less abundant than had been expected, and lack 
of time did not permit a careful study of this group. Owing 
to the very slight tide — only about one foot — very little col- 
lecting can be done from the shore, and we were not provided 
with apparatus for collecting in deep water. The most interest- 
ing forms noted were the marine Siphonez, Caulerpa, Halimeda, 
and others. Probably this group is well represented and would 
repay careful study. Fungialso were less abundant than might 
have been anticipated. 
In considering the localities best fitted for the establishment 
of a laboratory, there is little question that the eastern part of 
the island offers much the best conditions, as here there is the 
maximum rainfall with the resulting luxuriant vegetation. Port 
Antonio, lying on the coast and being very accessible, as well 
as offering excellent living accommodations, is in many respects 
a favorable locality, but is rather too far from the higher alti- 
tudes and virgin forest. Bath is nearer to the latter and is 
fairly easy of access, but is seven miles inland. 
The writer cannot close this sketch without acknowledging 
the many kindnesses shown us on our trip by every one with 
whom we came in contact. Through the courtesy of the 
director of the island railways, Mr. McKinnon, we were pro- — 
vided with passes over all the lines, and were also offered 
other help which lack of time prevented our accepting. The 
governor of Jamaica, Sir Henry Blake, and the authorities of 
the Institute of Jamaica also showed great interest in our 
plans and helped us in many ways. It is to Mr. W. Fawcett, 
however, that we are especially indebted, and to whom much : 
of the success of our trip is due. a
