VOYAGE. 



The Lamport and Holt Steamship line have inaugurated a regular 

 service between New York and Brazil of one vessel every two weeks. 

 The steamship Vandyek on which our expedition sailed for Brazil left 

 New York October 4, 1913, arrived at the first stop, the Island of Barba- 

 does, October 10th, and reached Bahia. the second stop, October 18th. 

 During the stop of the Vandyek at Bahia our party visited Cabnlla, a 

 suburb of Bahia, in order to visit a famous orange grove at that place 

 and determine the exact time of ripeninsr of navel fruits in this district. 

 "We found that the navel trees in Bahia have different habits of produc- 

 ing ripe fruits; one kind developing ripe fruits mainly in November, 

 December and January, the spring and summer crop commonly called 

 the December crop ; another type bearing ripe fruits mainly in June, 

 July and August, the winter crop ; and still another type producing 

 ripe oranges at more or less regular intervals during the entire year.
