BOULDER COUNTY. 
(Area, 768 square miles; estimated forest area, 275 square miles. ) 
This county is situated in the north-central part of the State. It is 
bordered on-the west by the main Rocky Mountain range, and is well 
watered by streams tributary to the South Platte River. The western 
half is mountainous and timbered; about one-third of the timber is 
good, and one-fourth burned over, with a young growth following. The 
principal arborescent species are, Yellow and White Pine, Spruce, and | 
Fir. The timber is scattered over nearly all of the mountainous por- 
tions of the county, while along the foot of the range it is quite dense. 
After forest fires, the second growth usually consists of wild Maple, 
Alder, and shrubs. 
The eastern third of the county is rolling and valley-land, most of 
which is suitable for farming purposes. : 
CHAFFEE COUNTY. 
(Area, 900 square miles; estimated forest area, 500 square miles. ) 
This county, which occupies a central position in the State, is almost 
surrounded by mountainranges. It contains a large proportion of farm- 
ing and grazing land, and is aco watered by the Arkansas River 
and its tributaries. 
About two-thirds of the county is timbered. Near the summits of the 
mountains is Spruce, below them Yellow Pine, and in the foot-hills and 
mesas Pifion and Scrub Pine; aleng the streams are Willow—(Black or 
Narrow-leafed), Cotton-wood, and Aspen. The timber land is mainly sit- 
uated along the eastern slope of the Continental Divide, which forms 
the western boundary of the county, and in the range of hills between 
the South Park and the Arkansas River. The timber in the more open 
valleys of the river is largely Pifion, great quantities of which have been 
cut and converted into charcoal for the use of the smelters of Leadvilie, 
Pueblo, and Denver. There are a number of saw-mills, and a great 
many railway cross-ties are being cut. This consumes the best. part of 
the timber. 
CLEAR CREEK COUNTY. 
(Area, 450 square miles; estimated forest area, 200 square miles. ) 
This is pre-eminently a mountainous county. The main snowy range, 
with an altitude of 14,000 feet and more, extends along the entire western 
boundary. It sends off lofty spurs, many of the peaks rising far above 
the timber line, and these, in parallel ranges, traverse the county from
