Other observers left the dam at 9:00 a.m. m anothe_-° boat, arriving 

 at Ellsworth cannery, 33 miles beljw Bonneville, a-c noon. Floats were 

 seen along the route for the first 1£ miles below Bonneville and although 

 observations were continued at Ellsworth cannery until E :00 po^..., no floats 

 were seen. Therefore, more than 16 hours were required for the floats to 

 travel the 33 miles from Bonneville to the cannery. 



At 2:11 p.m., the observers otationed at Cape Horn started back 

 upstream and examined those sections of the Washington shore where dead 

 fish had previously been found. .Th«iy fo-and 18 red-top arid II white-top 

 floats beached on the Washington shore between Cape Horn and Butler's
