 accompany, the first explorers. The man who wishes to 

 do the best scientific work in the wilderness must not try 

 to combine incompatible types of work nor to cover too 

 much ground in too short a time. 



There is no better example of the kind of zoologist 

 who does first-class field-work in the wilderness than John 

 D. Haseman, who spent from 1907 to 1910 in painstak-

 tent of South American territory hitherto only partially 

 known or quite unexplored. Haseman's primary object 

 was to study the characteristics and distribution of South 

 American fishes, but as a matter of fact he studied at first 

 hand many other more or less kindred subjects, as may 

 be seen in his remarks on the Indians and in his excellent 

 pamphlet on "Some Factors of Geographical Distribution 

 in South America." 



Haseman made his long journey with a very slender 

 equipment, his extraordinarily successful field-work being 

 due to his bodily health and vigor and his resourcefulness, 

 self-reliance, and resolution. His writings are rendered 

 valuable by his accuracy and common sense. The need 

 of the former of these two attributes will be appreciated 

 by whoever has studied the really scandalous fictions 

 which have been published as genuine by some modern 

 "explorers" and adventurers in South America ;* and the

 investigate the formal and official charges made by Colonel Rondon, 

 an officer and gentleman of the highest repute, against Mr. Savage 

 Landor. Colonel Rondon, in an official report to the Brazilian 

 Government, has written a scathing review of Mr. Landor. He 

 states that Mr. Savage Landor did not perform» and did not even 

 attempt to perform, the work he had contracted to do in explora-
