lakelets instead of swamps. In Hartford Township, which borders Water- 

 vliet on the east, there are till plains, sand plains, and island-like billowy- 

 belts over about two-thirds of the township, but the two tiers of sections in 

 the east contain an elevated part of the moraine. Lawrence Township, 

 which lies east of Hartford, has a prominent part of the moraine occupying 

 nearly the whole of its surface, there being but two notable exceptions, the 

 valley of the Pawpaw River, which passes from east to west through the 

 northern part of the township, and the overwash apron which borders 

 the moraine in the east part of the township. The overwash apron swings 

 around the moraine across Hamilton Township, which lies south of Law- 

 rence, and thus in the north part of T. 4 S., as well as in T. 3 S., the 

 morainic border has for several miles a nearly east to west trend. Contin- 

 uing its course in T. 4 S., we find the morainic border turning southwest 

 near Keeler Center and entering Cass County from the southwest corner of 

 Keeler Township, cutting off a section or more of this county in its extreme 

 northwest corner, then entering the eastern part of Pipestone Township, 

 Berrien County. 



Passing westward through T. 4 S., the moraine becomes prominent in 

 western Keeler, Bainbridge, and eastern Benton townships. It divides in 

 the southern part of Bainbridge township at Pipestone Lake, and from this 

 point south, in Pipestone Township, incloses a low belt along the Pipestone 

 River in which flowing wells have been obtained. The eastern limb passes 

 southwest through the southeastern part of Pipestone Township, and the 

 western limb passes southwest across the northwest corner of Pipestone 

 Township into Sodus Township and occupies the eastern portion of this 

 township to the St. Joseph River. 



From Benton Township southward nearly to the Indiana line the west- 

 ern or inner border is more sharply defined than it is north of this township. 

 It rises abruptly 100 feet or more above the swamps or till plains which lie 

 along the foot of the range of sandy hills which form its front. For a few 

 miles in southern Berrien County, Michigan, this border is not abrupt, but 

 upon passing into Laporte County, Indiana, it again becomes abrupt and 

 continues so across Laporte and Porter counties. Along the eastern or outer 

 border in Berrien County lakes are numerous. They are usually in deep 

 depressions 50 feet or more below bordering portions of the moraine. There 

 are also lakes on the gravel plain outside the moraine, occupying basins
