48 ANNUAL REPORT, 
New Auburn, in Sibley county, the timber line is on the east of the 
direct line. Near the former village, about four miles north, 
some large patches of timber, containing large oaks on tof 
the main road, and the line seems to swell several miles to the w west, 
but at Arlington the timber is entirely on the east of the town. Be- 
tween New Auburn and Glencoe the timber line runs about a mile 
east of the main road, and about three miles east of Glencoe. It is 
found again at four miles north of Glencoe. Thence it continues 
west and northwest to Darwin on the St. Paul and Pacific Railroad. 
North of that its exact location has not been traced. It seems to 
run still northwestwardly, and to include the region of small lakes in 
Pope, Douglas and Otter Tail counties and the region known as the 
Leaf Mountains, in the wooded portion. North of the St. Paul and 
Pacific Railroad, the Big Woods widen out rapidly, both to the east 
and west, merging into the general forest of the northern part of the 
State. The term is strictly, and originally, only applicable to the 
spur that includes the Lower Minnesota valley, extending nearly to 
the Iowa line. The writer has crossed this spur in a number of di- 
rections. In passing from Far.cington in Dakota county to Shako- 
pee in Scott county the following species of trees and shrubs were 
seen. For ten or twelve miles after entering the woods very few 
large trees were seen, the oak shrubs being the largest, and almost 
the only treelike vegetation. About half way to the Minnesota river 
the maple and large elms, bass and ironwood appear.
