From Scientific American Supplement, December 12, 1891:
"The wild duck is a shy bird, apt to spread his wings and change his quarters when a noble sportsman is seen approaching his habitation with a fowling piece. You have heard of the ass who put on a lion's skin, and wandered out into the wilderness and brayed. I have elaborated a device of equal ingenuity and more convincing realism. It is my habit during the duck-shooting season to put on the skin of a Blondin donkey and so roam among the sedges bordering on the lakes where wild ducks most do congregate. I have cut a hole in the face to see through, and other holes in the legs to put my hands through."
