Benton Group

Fig. 2. Columnar section for the Wattenberg area of the Denver Basin. The primary source rocks are the shales and limestones of the Dakota Group, Benton Group, and Niobrara Formation. The most important hydrocarbon reservoirs are the Dakota J Sandstone and the Hygiene and Terry sandstones of the Middle Pierre Shale. The Lyons Sandstone, Codell Sandstone of the Benton Group, and limestone of the Niobrara Formation also produce hydrocarbons...

The Siphonaptera is another group where a volatile sex pheromone is yet to be demonstrated, although a contact sex pheromone has been demonstrated in preliminary experiments (Ralph Charlton, personal communication). The source and nature of this contact pheromone is yet to be deciphered. Fleas have been speculated to use a certain wavelength of light, C02, and visual and thermal stimuli for host localization, as traps that present these kinds of stimuli seem to be effective in trapping fleas (Benton and Lee, 1965 Osbrink and Rust, 1985 Dryden and Broce, 1993). 

Bentonite is a montmorillonite-containing clay, named after its source, Fort Benton, Mont. It is among the group of clays commonly referred to as bleaching earths which require activation by an acidic treatment process. Fuller s earth, another montmorillonite-containing clay, is not treated by any activation process before use hence its description as a raw bleaching earth . These and other adsorbent clays may be employed in the inventive process.

I viewed a reproduction at Mary s City of David, Benton Harbor, MI, in July 2012. The original clipping was donated with other group archives to Mary s City of David collection at Hamilton College, Clinton, New York, which I also visited in July 2012 as part of a Mellon Foundation-funded Central New York Humanities Corridor Visiting Scholar grant.
