Figure 7. --Movements of bottles released from Sheboygan to Sheboygan Reef, June 26 

 and 27, and from Sheboygan Reef to Racine, June 27, 1931. 



Waukegan to St. Joseph 



Of the 30 bottles (table 8) released along 

 the transect on June 30, 1931, 24 (80 percent) 

 were recovered (fig. 8). Eight were collected 

 along the southern shore in Indiana, two moved 

 southwest, seven northwest, two southeast, 

 and five northeast. 



The nine bottles from the western part were 

 discovered from near Highland Park, Illinois, 

 to Sheboygan, Wisconsin. Their travel ranged 

 from 7-95 miles, an average of 48.0, in 5-57 



days, an average of 42.1. The eight bottles 

 recovered toward the south landed in 41-57 

 days, an average of 47.5, and reached the 

 shores at distances of 33-50 miles, an average 

 of 40.9. The seven recoveries along the eastern 

 shore extended from 6 miles south of St. 

 Joseph, Michigan, to Big Sable Light, 8 miles 

 north of Ludington, Michigan. Six of these 

 bottles traveled 32-68 miles, an average of 

 48.8, and were recovered in 29-60 days, an 

 average of 51.8; the seventh one was found 

 130 miles distant and was discovered on the 

 94th day.
