218 IOWA STUDIES IN NATURAL HISTORY 
Laboratory at St. Johns was especially helpful. He furnished 
books and maps, offered free access to unpublished notes on the 
geology of the island, and not only served as guide but fur- 
nished conveyance to remote parts, thereby saving valuable time. 
In the field and in drives over the island, he contributed many 
interesting facts about the geology and natural history of the 
places visited that would otherwise have escaped attention. His 
home was the geologist’s headquarters while working in the 
neighborhood of St. Johns and his and Mrs. Collens’ unbounded 
hospitality is one of the pleasant recollections of the expedition. 
With rare good fortune an interview of a few hours was had 
with Sir Francis Watts, who came ashore at St. Johns while 
en route from New York to Barbados. Sir Francis formerly 
lived for many years in Antigua and he is remarkably well ac- 
qguainted with the geological and other natural features of the 
island. In spite of the regrettably brief conference, many very 
important facts and stimulating suggestions were learned which 
proved truly helpful in understanding some of the problems en- 
countered,—a few of which unfortunately were only hastily 
studied during our brief stay. Writers on the geology of An- 
tigua have differed more or less radically among themselves on 
several interesting points, due in many cases no doubt to a neces- 
sarily hasty examination of the field; but the keen observations 
of Sir Francis, extending over a long period of years, are well 
founded, and his conclusions are in conformity with the funda- 
mental geological history not only of Antigua, but of the whole 
Antillean province as well. 
A set of the land snails of Antigua and also a number of the 
much-eoveted Helicona of Barbuda were generously presented 
by Mr. W. R. Forrest of St. Johns. Mr. Forrest is well in- 
formed on the natural history of Antigua and has been a eol- 
lector and keen student there for many years. He freely 
offered many valuable suggestions about collecting grounds and 
exposures of interest to the geologist. A trip with him to the 
northwest part of the island proved very profitable. Mr. For- 
rest is a most pleasant and courteous gentleman and we regret 
that our acquaintance was necessarily so brief. 
Mr. Oliver Nugent of St. Johns kindly loaned some interest- 
ing papers dealing with the geology of Antigua. His grand- .
