In the photo below, we see Eloise Butler crossing the rustic bridge at the north end of the Mallard Pool. The year is 1932. She has physically weakened due in part to neuritis and from burns received in 1929 when a heating pad caught fire while she was sleeping. The development of this pool was long on gestation and short on actual building. She had dreamed for many years of creating a large sunlit aquatic pool for special plants and the site was to be at what was the north end of the Garden in her days, (North of the current back fence) where the wetland drainage and a stream from a spring join and drain towards an existing pond. At some early time Eloise placed an earthen dam where the water from the meadows and wetlands in the south part of the Garden could accumulate, forming a small open pool. In 1917 Eloise had it replaced by a dam of concrete. That pool was too shady, hence her desire for another, but she could not move the idea of a large pool to reality until 1932 when the pool was quickly constructed by an unemployed man she hired and another was employed to build a rustic bridge of tamarack poles to span the small stream the flowed into the pool. When a mallard was soon seen in it, it became the “mallard pool.” Eloise had planned extensive plantings around the pool and these were completed by Martha Crone in 1933.

By late 1939 curator Martha Crone was no longer tending that area of the Garden and it gradually returned to a wild state. By 1944 the area was officially abandoned. (details in Mallard Pool article) The concrete dam still fulfilled its function however, creating a small pool in the Garden and at some point a small bridge was placed across the water channel leading to that pool, in what is now the north end of the Garden wetland. That bridge was an old wood dock.
In the 1st photo below, we see the 1990s version of a rustic cedar bridge that replaced the old wood dock, as it looked on April 16, 2008. This bridge was installed in the winter of 1989/90. Not as elegant as the bridge of Tamarack poles that Eloise had on the Mallard Pool, but it did the job. The pool was dredged in 1992, a liner put in, a new rock dam put in place of the concrete dam, and the back fence was re-aligned and moved northward (away from the dam) to its current position along side the paved path. The pool is under consideration for restoration again today, as the progress of time and changes in the environment have worked their ways on the area. In the time of Eloise Butler there was more water draining from the wetland as springs were still active in the Garden. This pool in the the current Garden wetland has taken on the name of "mallard pool", but should not be mistaken as for the original. It is though, not inappropriate - as mallards do use it as the photo shows.
In the next photo we see the same area in May 2018, but further back, by the dam area, looking toward the position of the bridge.

Below: The pool area in the Garden may be entitled to take on the old "Mallard Pool" name as these Mallards find it of interest. They were found scouting out the pool area on April 29, 2008.
As a tribute to Cary George, the Friends of the Wildflower Garden raised funds to restore critical footpath structures in the Garden’s wetland habitat. These trail segments, including the wooden bridge next to "Mallard Pool" and the three wooden walkways south on Lady’s Slipper Lane, were popular among visitors and were very much in need of replacement. It was true for Cary, as it was for Eloise Butler, that the wetland is the heart of the Garden. We believe that this project in honor of the fourth Gardener to be a testimonial to his service as well as to the Founder and her vision.
These trail segments were redesigned and a boardwalk installed in July 2015 for safety and accessibility. Materials and workmanship of high quality will provide decades of use in this beautiful part of the Garden, where Cary worked so diligently to replant and nurture Eloise's Tamarack grove.
