648 EXPLOEATION AND COLLECTIONS. 



specimens were probably deposited in the herbarium of the University of 

 Pennsylvania, Philadelphia. 



1866. Henrik J. Krebs, who spent most of his life on St. Thomas, made a 

 short trip to New Providence in 1866. The plant collections made by him 

 on the island are deposited in the herbarium of the Botanical Museum 

 at Copenhagen. 



1867-8. Sir Rawson Wm. Rawson collected to some extent on New Providence, 

 and probably other islands, during his two years incumbency as Governor 

 of the Bahamas. His collections were sent to the British Museum. Dupli- 

 cates are to be found in herb. Kew and in Berlin. 



1874. Dr. Edward Palmer, well known as a collector upon the North American 

 mainland, visited Nassau in May, 1874. The algae collected by him were 

 studied and enumerated by Prof. D. C. Eaton [see Bibliography]. 



1875-1919. Lewis J. K. Brace began his collections in the Bahamas in 

 1875. He worked principally on New Providence until 1880, but also 

 secured material on Fortune Island or Long Cay, and Andros. His work 

 resulted in about 525 numbers, of which his personal series is now in the 

 herbarium of the New York Botanical Garden and duplicate sets in the 

 herbarium at Kew and that of the Field Museum. He began field work 

 for the survey resulting in this Flora in September, 1904 (see Britton & 

 Brace), and later in the same year was commissioned by the New York 

 Botanical Garden to make an exploration of the Abaco Islands, where he 

 collected as follows: Green Turtle Cay (1475-1515), Allen's Cay (1526-54), 

 Spanish Cay (1555-62), Man-o'-War Cay (1563-89), Pigeon Cay (1662- 

 73), Elbow Cay (1688-1712), and on the island of Abaco at Butler Cay 

 (1516-25), Marsh Harbor (1590-1661, 1713-53, 1787-1846), Great Cistern 

 (1674-87, 1754-86), Cherokee Sound (1847-9, 1898-1980, 1999, 2080-84, 

 2086), Eight Mile Bay (1850-97), opposite Cherokee Settlement (1981-98, 

 2064-79), Old Kerr's Point (2000-2036), and California road (2037-63), 

 a total of 611 numbers. Following this expedition he continued work on 

 New Providence in localities from which, from time to time, it became 

 necessary to have more material of previously secured species. 



In June, 1905, a commission was given him by both the New York 

 Botanical Garden and the Field Museum to continue on Great Bahama, the 

 work already undertaken there. (See Britton & Millspaugh.) On this 

 exploration he collected at Eight Mile Bocks (3633-5, 3671-3738), Dead- 

 man's Eeef (3631-2), and the western extremity of the island (3484-3630, 

 3636-37). He also collected on Garden Cay (3658-70), and visited (during 

 his sailings to and from Great Bahama) North Bimini (3461-75, 3479-83), 

 South Bimini (3476-8), North Cat Cay (3739-54), and Andros Island 

 (3755-6), and after returning to New Providence collected Nos. 3893-3918. 

 He was later commissioned by the New York Botanical Garden and the 

 Field Museum to make three further explorations. From these he has 

 returned over 1,800 numbers as follows: Bum Cay (3919-3993); Fortune 

 Island (3994-4179); Acklin's Island (4260-4471); Crooked Island (4533- 

 4776); and Andros (4876-5377 and 6657-7139). In the Andros work he
