In the logging industry the log end contains “end marks”. This refers to the markings made at the ends of the logs to determine their ownership. The tool used to create these markings is called the stamp hammer. This way to identify the owner of logs was used in Michigan as early as 1842 to ensure logs went to the correct mill and the correct log owner received the profits. Every log owner had their own authorized marking and it was illegal to either change or destroy this marking. Unmarked logs were considered “prizes” and could be divided among the different owners in a region. This log end is an example of a log that was illegally stolen, had its end sawn off, and was then re-marked with a different stamp.
Investigate: Historic Grand River Artifacts (September 2018) During the Investigate program, students will take the role of Museum curators and use close observation and critical thinking to discover the origin, meaning, and importance of real objects from the Museum’s Collection. Students will learn how to handle and study primary sources and will be pushed to consider how singular objects or groups of objects can tell meaningful stories about our place.
Learners will be able to analyze primary sources (artifacts and photographs) and make inferences about the story or significance of the sources.
Learners will be able to describe how the Grand River impacted the lives of people who lived in Grand Rapids between 1850 and 1910.
