JETHOU. 
EPARATED from the south-western extremity of Herm by a 
narrow channel only a few hundred yards wide—the navigable 
passage called La Percée—the small island of Jethou, or, to 
write it phonetically, Jetto, rises like a miniature mountain, flanked 
on each side at nearly equal distances by two symmetrical rocky 
islets called respectively Crevichon and Fauconniére. Away to the 
southward for two or three miles the sea is sprinkled with rocks of 
various shapes and sizes, so that the whole group as seen from 
Herin, or from a boat at sea, is exceedingly picturesque. 
Jethou itself is a round hummock of granite, conical in shape, 
but almost flat on the summit, which is a small plateau of cultivated 
land. The island is hardly more than halfa mile across at its widest 
part, and is said to measure a mile and a quarter around the base: 
it rises abruptly, so that everywhere the sides are steep and pre- 
cipitous, except towards the north, where the land slopes more 
gradually down to a rough pebbly beach. At this end of the island 
there is a small cluster of trees, some of them, especially Spanish 
chestnuts and sycamores, of considerable size, and of finer growth 
than would be looked for in such an exposed situation. In this 
comparatively sheltered corner are to be found the only three 
habitations,—two cottages and a larger house, the residence of an 
English gentleman who rents the island, and from whom permission 
to visit it must be obtained. ‘There are about fifty acres of arable 
land, and the soil is good, yielding fair crops of corn, potatoes, &c. 
The predominant rock is syenite, sometimes in a state of dis- 
integration, elsewhere solid and compact, often heaped up in 
tabular masses, which bear a striking resemblance to the so-called 
Druids’ Altars. Rivulets and pools are entirely absent: low-lying 
commons and sandy shores are also wanting: and in these respects 
Jethou differs from the sister-island of Herm, which otherwise it 
closely resembles. 
When Professor C. C. Babington visited the Channel Islands in 
the year 1838, he devoted a day to Jethou (July 21st), and gathered 
the 113 flowering plants and 2 ferns which he afterwards recorded in 
his Flora Sarnica. On the 25th of June, 1890, during an excursion 
made to Jethou by the members of the Guernsey Society of Natural 
Science, I catalogued 135 flowering plants and seven ferns, of which 
fifty-six species were not noted in the Alora Sarnica. These were
