Antillean Stream to the Florida Strait from regions to the eastward 

 and southward. 



But in the winter months, when the North-east Trade blows freshest 

 and is often very northerly, these islands are also the recipient of 

 drift from the northward and eastward, probably mostly material 

 that would otherwise have passed to the eastward of the Turks 

 Group, but is thrown back on the beaches by the strong " northers " 

 that are not infrequent in this season. During the winter bottle- 

 drift may even arrive at these islands from the vicinity of Bermuda. 

 Dr. Schott (p. 13) in this connection observes that the N.W. direction 

 of the drift in the seas between the Bahamian and Bermudian Islands 

 is not always illustrated by the bottle -drift, and he gives a case where 

 a bottle thrown over early in February about 150 miles S.S.W. of 

 the Bermudas was recovered on the Turks Group forty-nine days 

 later, the distance covered being 542 miles. 



I will first give the data concerning bottles stranded on the islands 

 forming the south-eastern extremity of the Bahamas, namely, the 

 Turks and Caicos Islands and the two Inaguas. They are mainly 

 supplied in the American charts and in Dr. Schott's paper; but a 

 few are taken from the Nautical Magazine for 1852. The following 

 is a grouping of the materials according to their starting-places. 



Sources of bottle-drift found on the south-eastern islands of the 



Bahamas, 



A. Vicinity of the Azores within a radius of 400 



miles 



B. Off the south-west coast of Ireland, 260 



miles distant 



C. Off the coast of Portugal, near Lisbon, 50 



miles from land 



D. In the vicinity of Madeira and the Canary 



Islands within a radius of 160 miles . 



E. About 120 miles off Cape Blanco and half- 



way between the Canary and Cape Verde 

 Islands 



F. In the vicinity of the Cape Verde Islands 



within a radius of 250 miles to the north, 

 south, and west 



G. In mid-ocean, 1000 to 1500 miles E.-E.S.E. 



of the Turks Islands 



H. Between 100 and 350 miles N.-E.N.E. of 



the Turks Islands between December and 

 March 



I. Between Bermuda and the Bahamas during 



January and February 



J. Off Cape Hatteras
