The experiments reported herein seemed to show that low temperatures hinder the intake of water.....Salix with very abundant young leaves shows a greater and quicker response to a cold solution. Large numbers of cultures were used for each experiment and those plants compared whose water contents were closest at the beginning of the experiment.

The article presented here is the only one known where Edith Purer co-authored an article with another scientist. Delzie Demaree, the co-author had an interesting and colorful life as a botanist and naturalist. Her name is listed first and his name second is an interesting situation considering it was a male-biased society. Her last name comes after his in the alphabet, which supports a conclusion that she was the senior author and he assisted her. She must have traveled to Stanford University to conduct the research. I have learned that her co-author, Delzie Demaree, did his PhD work at Stanford University. He completed his PhD in 1932 and Edith Purer completed her PhD only one year later in 1933. They were both recent PhD's at the time the research paper was published in 1935.

Delzie Demaree lived from 1889 to 1987, and Edith Purer was born in 1895, so he was six years older than her. According to some preliminary biographical research on Delzie Demaree, he had an interesting life as a botanist. He apparently refused to buy a car. Instead, he would board a bus and ask the driver to let him off in the middle of nowhere. Then he'd hike into the woods, collect fro the day, and hike back to the road to await the next bus. Demaree began work on the flora of Arkansas in the 1920s, then went to Stanford University, but returned in to complete a catalogue of Arkansas plants in 1943. He self-published his results in a scientific journal that he established, called Taxodium, and ciruclated among friends. He most likely gave a copy to Edith Purer. It is known that around 1930, Demaree explored for plants in Baja California. There is a photo of him sitting in a chair with his plant collecting press and gun, while dressed in a suit, tie, and jeans.

The article written by Edith Purer and Delzie Demaree is only two pages. The text is nearly confined to one page with an experimental table occupying nearly the entire second page. It is the shortest article known by Edith Purer, but it is an abstract-like scientific paper that appears to have been presented at an annual conference in Indianopolis for the Indiana Academy of Sciences, so this may explain the brevity of the writing.

It is speculated that Edith Purer would have traveled to Indianopolis, Indiana in late fall, 1934 to present the research findings at the annual meeting of the Indiana Academy of Science. She may also have visited Indiana Dunes State Park in spring, 1934. Did she travel there with Delzie Demaree together? Did she travel by train? Further research is needed to discover if these travels did occur.
