Log Marks Activity - Lesson Plan
Loggers cut Michigan's white pine during the winter. Men and teams could work easily
among the trees when the swampy forest ground was frozen. They piled the logs on the banks
of rivers to wait for the spring thaw. When the rivers were swollen with water from the
melting snows, the loggers floated the logs to the sawmills. The logs of many lumber
companies floated together to the sawmill.
Owners used a heavy marking hammer to mark each end of their logs with a special
design, a "log mark." The log mark let everyone know who owned the log. The log
mark was first used near Muskegon in 1842. Each owner registered his mark with the county
government. Log piracy was one of the earliest types of "industrial" crime in
Michigan. Log thieves sometimes waited for the spring log drives and pulled choice logs
from the river. They cut off the log ends and remarked the logs with their own mark.
- Students will be able to explain the purpose of the log mark during 19th-century log
- Students will be able to tell how log marks were applied to logs.
- Students will be able to describe the various parts of the designs of log marks.
- Students will design a personal "log mark."
Michigan Social Studies Curriculum Content Standards
This lesson presents an opportunity to address, in part, these standards:
- 3.1.2. CIVIC PERSPECTIVE: Describe consequences of not having rules.
- 2.3.4. GEOGRAPHIC PERSPECTIVE: Describe major kinds of economic activity and explain the
factors influencing their location.
Michigan log marks (copy for each student or drawn on poster or
chalkboard); pencil and paper; optional: 1/4" craft cork and wood blocks or potatoes
cut in half; knife to cut own log mark design for stamping; stamp pad or tempera paint.
Ask students to examine the different log marks used by Michigan lumbering companies.
Discuss the different designs used: words, initials, symbols, figures, and combinations of
these. Discuss ways in which log marks in Michigan and cattle brands of the west were
similar. How were brands applied to cattle? How were marking hammers used to emboss log
marks in the cut ends of logs? Compare and contrast log piracy and cattle rustling.
Ask students to draw their own personal "log mark" using pencil and paper. Is
there a special design related to their name, personal characteristics, or favorite things
that would have a special meaning to them?
Optional: Have students transfer the "log mark" design to 1/4" craft
cork and cut out. Glue the craft cork to a wooden block. Permit students to stamp the
design on their papers using an ink pad. Or, have all students stamp their designs on one
large piece of Kraft paper to make a classroom poster. Each design may also be cut into
the cut side of a potato, then stamped using tempera paint. Supervise any use of knives
Questions for Discussion or Research
- Why did lumbermen mark their logs?
- What different designs do you see in the log marks?
- What meanings might the designs have had to the lumbermen who owned them?
- Why should the log buyers purchase logs from the honest lumber company rather than from
the log thief, even though the thief might sell the stolen logs for less money?
- Why might we still find ends of logs with log marks from the 19th century in or along
Michigan rivers? (They were cut off and left there by log thieves.)
At the Museum
- Look for the log marking hammers. What symbol is on the end of each?
- Find the log mark display. What might some of the designs have symbolized?
- Watch the 13-minute program in the "Lumber Baron's Theater" about
Michigan's lumbering era to learn more about how shanty boys lived.

Some Michigan Log Marks
Other Lumbering Activities
How Large Were the Logs?
The white pine trees found by the first loggers in Michigan were hundreds of years old,
tall and straight. Most trees grew 80-120 feet tall with a diameter of three to four feet.
But loggers reported finding some trees as tall as 150 to 200 feet. The diameter of the
trunk of these trees was five to seven feet.
Cut Kraft paper (tape several pieces together if necessary) to represent the cut end of
a five foot or wider diameter white pine log. Draw circles on it to represent the tree
rings. Tape the "log end" on the wall with one end at floor level. Have students
stand next to the log and mark their height on it.
Discuss the length of time needed to grow trees of the size of Michigan's original
white pines. Learn ways today's loggers are trying to cultivate renewable forests for
long-term use and enjoyment.
Rivers and Watersheds
Give each student a map of Michigan and/or project a map on the classroom screen. Trace
and highlight the following rivers and watershed areas:
Menominee/Brule/Paint/Michigamme/Sturgeon/Little Cedar Rivers
Pere Marquette River
Thunder Bay River
Muskegon/Little Muskegon Rivers
Betsie River Basin
Grand/Rogue/Flat/Maple/Looking Glass/Red Cedar/Thornapple Rivers
Discuss the settlement of towns and cities along one or more of the rivers. How does
the river help you understand the settlement pattern? Find out which towns had sawmills.
