clearly enlarged basal cells which later in the year, when the water is lower, will 

 form in the bed deep carpets of luxuriant green. Thick tufts of Hygrohypnum 

 ochraceum are mingled with the latter species and, in deep ravines, the dark 

 strands of Eurynchium rusciforme harmonize well with the forest shade, with ends 

 swaying in the swish of clear, cool waters, where Fontinalis delights to dwell. 



However, these are but glimpses of the world of feather mosses and the best 

 advice we know is to grasp the key to field and woods and hasten away, no matter 

 what the season, leaving dark care behind, to seek forest and streamside, to taste 

 the refreshment of sweet waters in the fulness of the truest pleasure it is given 

 man to enjoy; where you may study the genus Hypnum, in the best way of all: 

 at first hand, close to Nature's heart.

A PRELIMINARY RFPORT, WITH NOTES, ON THF LICHENS FOUND 

 NEAR THE CINCHONA BOTANICAL STATION, 

 JAMAICA, BRITISH WEST INDIES 



Charles C. Plitt 



During June and July of 1919, it was my good fortune to spend a vacation 

 at the Government Laboratory, on the summit of Cinchona Hill, on the island of 

 Jamaica. This Hill has an altitude of 5000 feet, the laboratory and gardens, and 

 residence, occupy its summit.^ In our party were Professor Duncan S. Johnson 

 of The Johns Hopkins University, through whose efforts the trip was arranged 

 and made a success, Mr. William Seifriz, Mr. Louis Pessin, and the writer, mem- 

 bers of the Botanical Seminar of the University. The four of us were comfortably 

 housed at the residence, "Belle Vue Cottage," said to be the highest dwelling of 

 any pretensions in the West Indies.^ Not far away were our servants' quarters; 

 to the rear of us, and at higher elevation were the laboratories; around us and 

 covering many acres were the gardens with their numerous trees, shrubs, and 

 herbs, grown here for experimental purposes. Among them were Casuarina, 

 Grevillea, Callitris, Callistemon, gigantic Eucalyptus trees of several species, 

 Cordyline, Gordonia, and dozens of other plants of interest to the botanist. 



As I am interested in the Lichens, it was to them that I turned my attention. 

 Scarcely a day passed that I did not go out to collect specimens. It was not long 

 before my table was simply packed with material in various stages of preparation, 

 some dry, and ready to be sent home, some almost so, some just collected. As 

 soon as collected, I tried as far as possible to assort my material, and, if I could 

 decide upon its generic name, this was appended. I thus soon had piles of Clado- 

 nia, of Sticta, of Usnea, of Leptogium, of Graphis, of Lecanora, of Parmelia, of
