the St. Joseph, to form the Maumee, at Fort Wayne, Indiana, 
presents the same peculiar features as the St. Joseph. All 
its tributaries are from the south and west; north and east 
of it the drainage is from it, and its right bank is formed by 
a continuation of the same ridge. 
This ridge then runs one hundred and twenty miles across 
the drainage system of the region, and is cut by a water 
course in that distance at but one point, and that the lowest 
in the valley. That it does not consist of rock in situ may be 
affirmed from the fact that it crosses the outcrops of beds of 
the Waverly, Huron, Hamilton, Corniferous and Waterlime 
groups. That it is a terminal glacial moraine, is the only 
explanation I can offer of its existence. 
Some other facts appear to support this view. 
Lower down, the Maumee receives another pair of tribu- 
taries, the Auglaize river and Bean creek. They, too, are 
determined by a ridge, and present, somewhat less perfectly, 
all the peculiarities of the first pair. Explaining this ridge 
in the same manner, we have here two parallel, concentric, 
crescent-shaped, terminal moraines presenting their convexi- 
ties toward the south west. 
Let us now seein what relation these stand to the glacial 
strie. On the islands and mainland in the vicinity of 
Sandusky City, these striz bear ten or fifteen degrees south 
of West; about Toledo, thirty-five degrees; near Defiance, 
Ohio, due south west; and in the vicinity of Lima and Van 
Wert, Ohio, from fifteen to thirty-five degrees west of south. 
We have it thus recorded, that the ice moved west through 
the west end of Lake Erie, and then curved in the Maumee 
valley toward the south, a motion entirely in harmony with 
the position of the moraines, so that I think we may fairly 
conclude that, as the great ice-sheet retreated, its border was 
lobed in conformity to the topography of its bed, that one of 
these lobes occupied the Maumee valley, and that when this 
margin delayed or reversed its retrograde motion, it marked 
its outline, at two stages at least, by forming terminal 
moraines. .
