MR. ROLLO H. BECK 



M'ide experience and much practical knowledge, coupled with a boundless enthusiasm 

 for the work, have made Mr. Beck one of the most successful bird collectors in a region 

 where such collecting is accomplished only with the greatest difficulty and even danger. 

 Through his efforts on the Brewster-Sanford Expedition to South America, there is now 

 deposited in the American Museum the most complete representation of Tubinares in the 

 world
