Extract from Schoolcraft’s narrative of the expedition un- 
der Gov. Cass in 1820, 
“ The junction of this river [Fox,] with Green Bay, affords 
one of the most favorable positions for witnessing a phenom- 
enon, which has attracted the attention of travellers from 
of presenting an outline of those facts, which have been 
observed by oth ing i i iti 
“In the year 1689, the Baron La Hontan, on reaching 
Green Bay, remarks, that where the Fox river is discharged 
into the Bay, he observed the water of the lake swell three 
feet high, in the space of twenty-four hours, and decrease as 
much in the same length of time. He also noticed a con- 
trariety, and conflict of currents in the narrow strait which 
connects Lakes Huron and Michigan which” he says, “ are 
so strong, that they sometimes suck in the fishing nets, al- 
though they are two or three leagues off. In some seasons, 
it so falls out, that the currents run three days eastward—two 
days to the west—one to the south—and four to the noth- 
ward; sometimes more and sometimes less. The cause of 
this diversity of currents could never be fathomed, for in a 
calm, they will run in the space of one day, to all points of 
the compass, witliout any limitation of time, so that. the de- 
cision of this matter must be left to the disciples.of Coper- 
nicus. 
“In 1721, Charlevoix remarks similar appearances, but 
treats the subject with unusual brevity, evidently, from the 
difficulties which occurred to him, in giving any satisfactory 
explanation. He supposes Lakes Huron and Michi to 
be alternately discharged into each other through the strait
