Many couples approaching sixty and planning retirement might buy a 

 camper and think about a little serious fishing. Bill and Jan Street 

 bought two Travelalls, hired Doug Lay, a young mammalogist, and 

 took off to scour the mountains, deserts, and river valleys of Iran for 

 wildlife specimens to enrich Field Museum's collections. They started 

 by hunting red sheep two miles high in the Elburz Mountains and 

 went on from there. During the next six months, they traveled nearly 

 15,000 miles and collected nearly 3,500 mammals, from bears to bats. 

 They also collected hundreds of birds, reptiles, amphibians, and fish, 

 complete with thousands of fleas, ticks, and mites — all equally valu- 

 able for study. Thanks to their efforts, Field Museum now houses one 

 of the world's finest collections of Iranian fauna. 



But as history moved on, the Streets found that they had also 

 captured a last view of an ancient culture on the brink of change. Their 

 notes and photographs illuminate the vast political eruption that fol- 

 lowed. This, and the lengthening roll of research papers based on 

 their collections, gives lasting value to the Iranian adventures of three 

 Americans who learned the scientific expedition business by doing it.
