and clay moraines extending from northeast to southwest. 

 This area includes the highest land in the county, one hill 

 exceeding and several approaching iioo feet in altitude. Most 

 of the area is high and rolling. 



The old beach, marking the limits of the Lake Plain District, 

 runs northeast from Ypsilanti to the county line above Cherry 

 Hill, and southwest through Stony Creek to a point on the 

 county line about eight miles west of Milan. 



The native upland forests of the Interlobate Moraine Dis- 

 trict were composed chiefly of red, yellow, and white oak, 

 with some smooth-bark hickory and sugar maple and a few 

 shag-bark hickories. Here were also large areas of creeping 

 jvmiper and a few small patches of ground hemlock (yew). 

 On the flood-plains of the rivers and lakes were quite exten- 

 sive swampy forests of soft maple, black ash, and white elm. 

 Swamp oak and whitewood grew commonly in the drier situa- 

 tions toward the edge of the swamp conditions. The red-bud 

 and red cedar were characteristic of the river banks. White 

 pine probably never grew in the county, although a few trees 

 occur on the south bank of the Huron River near Hamburg, 

 a few miles north of the county line. 



Tamarack bogs, some of large size, are abundant in the 

 Interlobate Moraine District and occur commonly also in the 

 Clay Morainic District, but are practically wanting in the 

 Lake Plain District. 



The Clay Morainic District was originally dominated by 

 forests of oak and hickorv'. Several kinds of oaks, white ash, 

 and several species of hickories, with shagbark most charac- 

 teristic, were most abundant. Mixed with these w^ere elm, 

 beech, sugar maple, black walnut, and butternut. On the 

 higher ground many stands of quaking aspen were found. 

 The forest was quite dense and little underbrush normally
