Fig. 86.— Our boat on the Nushagak River, off Kakwak. Approximately 

 600 miles of the Nushagak and affluent rivers were covered in this boat, 

 which also carried our gasoline, provisions, empty boxes, specimens, and 

 tools. 



Fig. 87.— Nushagak River, June 5. Deep snow on north bank, 30 miles 

 above Dillingham. In places the snow and ice were still up to 10 feet in 

 thickness. The frozen ground in these regions constitutes a great obstacle 

 to excavation.
