Arboretum Landscape Teaching Aid Series: A Fence Long Gone Marked A Boundary (3.19498)
Date: 1940 – 1960Creator: Watts, May Theilgaard
Type: Drawing
Description:Primarily textual teaching aid depicting Arboretum landscape. This material shows how a fence once marked a boundary through a forest.
Header: A fence (long gone) marked a boundary through a forest (long gone)
Text and illustrations from top to bottom:
- [Depicted in stylized scroll] The Record:
- 1. A long row of trees: red oaks, white oaks, and ironwood [an illustration of a row of trees]
- 2. the soil profile on both sides of this row [arrow pointing right to illustration of a cross-section of soil]
- Interpreting the record:
- 1) Because red oaks and ironwoods belong in rich (mesophytic) woods, and
- 2) because a thin layer of black soil on top of clay is typical of forests in this area (but not of prairies) and
- 3) because there would have been forest-margin trees, like hawthorn, if this fence had edged a forest - We read the record as above [arrow extending upward to header]
