Abstract
A stratigraphical and statistical study was made of the microfossils in the marginal mat of a bog lake located near the Limnological Laboratories of the Wisconsin Geological and Natural History Survey at Trout Lake, Wisconsin. The fossils indicate that the regional flora was dominated, early in its history by a gymnosperm element, but was gradually replaced by angiosperms. The use of microfossils in determining the vertical distribution of limnic sediments in bog deposits was found to be an accurate method. The fossils used in this connection were sponge spicules and internal leaf trichomes of water lilies.
