THE VALPARAISO MORAINIC SYSTEM. 351 



that near Gobies, rising nearly 150 feet above the Pawpaw River swamps, 

 4 to 6 miles west of the village of Pawpaw, and having a breadth from the 

 swamp on the north to an overwash apron on the south of only 1£ to 2 

 miles. 



Waverly Township is much of it comparatively level and swampy, but 

 the topography of the northwestern part is morainic. This belt connects 

 on the north with the morainic belt which passes through western Bloom- 

 ingdale and eastern Columbia townships. 



In northeastern Arlington Township, which adjoins Waverly on the 

 west, is a swamp, which comprises about one-third of the township. It is 

 bordered on the north and east by the billowy belt in Columbia, Blooming- 

 ton, and Waverly townships, and on the southeast by an elevated billowy 

 tract in Arlington Township, which constitutes the most prominent portion 

 of the moraine in this tier of townships. This prominent morainic belt 

 extends southwest through southeastern Bangor Township to the Pawpaw 

 River, near Hartford. Its south border lies along the river for a distance 

 of nearly 10 miles from the east line of Arlington Township to the village 

 of Hartford. The river is also bordered on the south by a similar promi- 

 nent belt, which is described in connection with the next tier of townships. 



Bangor Township, which lies west of Arlington, has a series of swamps, 

 till plains, and island-like billowy tracts, the swamps and till plains together 

 occupying more than half of the surface. 



The moraine in this tier of townships, therefore, has a width of about 

 18 miles, and is highest in the middle portion, while in the tier of townships 

 on the north it is nearly as wide, but its most prominent part is the eastern 

 border. The curve in the outer border of the moraine makes the prominent 

 morainic belt south of Waverly Township the correlative of the morainic 

 belt near Gobies, in T. 1 S., and this belt is more prominent than the middle 

 portion in Arlington Township. The rule, therefore, still holds good — if 

 we overlook the break north of Pawpaw — that the eastern or outer border 

 is the highest part of the moraine, and this rule continues to apply as far 

 south as the Indiana line. 



In T. 3 S., at the western border of the morainic belt in Watervliet 

 Township, there is immediately east of the till ridge which cuts across its 

 northwest corner a series of till plains interspersed with island-like billowy 

 tracts and dotted with lakelets, differing from Bangor Township in having
