weeks' visit to Decatur county were made within a radius of 5 

 miles from this locality. The Brownsport mentioned in his 

 report is Brownsport Landing, on the Tennessee River, about 5 

 miles southeast of Dixon Spring, and 3 miles north of Vice 

 Landing. The furnace at this landing was erected in 1839-40. 

 The furnace west of Vice Landing, at present known as Browns- 

 port Furnace, was not put up until 1849, two years after Roemer's 

 visit. The mound glade mentioned in his report as occurring 

 about I mile west of Brownsport Landing can no longer be 

 identified. Several mound glades are known within a mile and 

 a half of the old Brownsport Landing. A mound glade is any 

 conical hill capped by the whitish clays and soft limestones of 

 the Brownsport bed. These whitish calcareous clays, for some 

 reason, form soils which are very unfavorable to the growth of 

 most plants. A scanty growth of grass, a considerable number 

 of cedars, and a few stunted oaks, too low to be called trees, 

 usually occupy a comparatively small part of the exposures, 

 leaving most of the hillside open. These open spaces on the 

 hill sides are known as glades. Owing to the white clays, these 

 glades are visible for long distances and are often conspicuous 

 landmarks. At the base they are often edged with red, owing 

 to the presence of the Dixon bed. One of these mound glades 

 occurs about a quarter of a mile north of the home of Noah 

 Butler, on the road from Vice to Perry ville, 2)^, miles north of 

 Vice. Another, not exposing the Dixon bed, occurs about half 

 a mile farther west. Here the Brownsport bed has a thickness 

 of at least 93 feet. Fortunately the identification of the mound 

 glade of Roemer is a matter of little importance, since the species 

 cited from this locality occur at numerous localities elsewhere. 

 Several glades occur on the road leading eastward from Dixon 

 Spring to the river, and numerous glades occur south and south- 

 west of the spring, within the radius of a mile. Glades are also 

 found between Dixon Spring and Perryville, but most of the 

 exposures near the road belong to the Glenkirk and Dixon beds. 

 All of the species described by Roemer were obtained in the 

 glades and therefore belong to the Brownsport horizon.
