There isn't very much known about this unique illustrator. Perhaps the search engines will add some links in the future. He was also a painter but for me, these are much more interesting than his easel paintings. Ask Art is a link to about eight paintings. Click on the following images to enlarge them.

I Googled the only Frederick van Beuren, Jr. and found this link.
"Through all the greenest, most delicious mysteries of the Schwarzwald." from the same article.
Harper's Monthly Magazine on the other hand, chose to run Stone's work in two colors, or black-and-white, and assigned him a lot of night scenes with and without animal life. This is from an article in the issue of September 1910 entitled simply "Night." The caption for the illustration reads, "The Fields are bathed in Moonlight. " I do not have the name of the writer.
"The Night Gloom of the Waters," from the same article.
"There is plenty of testimony that foxes do eat wild grapes." This illustration and the one which follows are from "The Harvest of the Wild Places," by Walter Prichard Eaton in the November 1914 issue of Harper's Monthly Magazine.
