erately steep slope up to the hills on the east side. Toward the 
west is a fairly level valley extending in for half a mile or so when 
it suddenly rises to a high grassy plateau used for pasturing stock, 
and locally called the “ Savanna.” This gap is dominated on each 
side by a high mountain, the one on the western side being very 
steep and having an altitude of 1010 feet. The chief town of the 
island, Ashton, is situated at its base. The principal house of the 
island, the home of former owners, is a large brick structure on a 
hill at the southeastern extremity of the island, about two miles 
from Ashton. Near it is a collection of about a hundred wattle- 
and-daub houses, comprising the village of Clifton. The rough 
land about the base of the hills is put under cotton and corn, and 
the Hat land under pigeon peas and sweet potatoes. The population 
is estimated at a little over 2000.

Just east of Union Island lies the small island of Prune. This 
key is mainly hat and swampy, but has two steep hills, one in the 
northeast, and the other in the southwest corner. The vegetation 
is mainly tail scrub and stunted trees, with numerous mangroves, 
especially in the northern part. This island is remarkable as being 
the only place where Dendroica ruficapilla occurs in abundance in 
the Lesser Antilles, south of Dominica. 
Near the town of Ashton is Frigate Pock, a tall rocky hill rising 
abruptly from the sea. 
The island of Carriacou, the largest and most important of the 
Grenadines, lies about eight miles south of Union Island, and 
twenty miles north of Grenada. It has an area of about 13 square 
miles. In the center of the island is a ridge, running from north to 
south, of fairly uniform height, with two peaks of considerable ele¬ 
vation, High North (980 feet), and Chapeau Carre (960 feet) at its 
southern end. A number of spurs run out from this ridge to the 
sea on either side, between which are remarkably level valleys 
extending in for some distance from the coast, and then rising 
rather abruptly to the central ridge. In many of these valleys, 
notably at Harvey Vale on the southern shore, near the town of 
Hillsboro’ on the west, and at Lauriston halfway between, there are 
extensive swamps. On the ridges and on many of the hillsides 
there is a large amount of scrubby growth and stunted trees; but 
on the gentler slopes and in the valleys the land is mostly taken up 
with the cultivation of “Marie Galante” cotton and Indian corn, as
