Figure 8.9 Carbon isotope composition of human bone collagen from the lower Illinois Valley, North America. The increase from <513C = —22%0 to —10%o at c. AD 1000 marks the arrival of maize agriculture at the end of the Late Woodland period (van der Merwe 1982). Reproduced by permission of American Scientist.

Fig. 9.9 Changes in 813C of human bone collagen in the lower Illinois valley prior to AD 800. The data indicate a shift from a C3 to a C4 based diet between AD 1000 and 1200 (Van der Merve, A. Proc. Br. Acad 11, 247 (1992))...

We are grateful to Dr. David Weisleder of this laboratory for obtaining the NMR spectral data and to Dr. J. M. Kingsolver of the USDA Systematic Entomology Laboratory for confirming the identity of our beetle species. The field experiments were conducted at the Illinois Valley Sand Field Experiment Station of the University of Illinois we are grateful to Mr. Stan Sipp for his cooperation there.

Illinois River Valley. A number of advantages of such a multi-proxy approach are clearly evident. Most notably, all of the carbon proxies, i.e. collagen, cholesterol and apatite, show parallel trends lending greater confidence to interpretations than would exist if only a single proxy was used.

In the bituminous coals of the US Illinois and Appalachian basins, arsenic primarily occurs in pyrite. The arsenian pyrite probably originated from subsurface fluids that existed about 270 million years ago during the formation of the Ouachita and Appalachian mountains (Goldhaber, Lee and Hatch, 2003). The arsenic-bearing fluids in the midcontinent Illinois Basin were primarily brines derived from surrounding sedimentary basins that were also responsible for the formation of the Mississippi Valley lead-zinc deposits. In contrast, the fluids that were responsible for the arsenian pyrites in the Appalachians (especially in the coals of the Warrior Basin of Alabama) were metamorphic and not as saline as those in the midcontinent (Goldhaber, Lee and Hatch, 2003). 

These cocoa substitutes are of two kinds. First, they consist of otherwise unprocessed bulking agents with added flavor and color. The bulking agents employed are soybean flour, modified food starches, dextrins, or mixtures thereof. They are definitely offered as extenders none of the manufacturers recommend that they be used as a total replacement for cocoa. Manufacturers include Cargill, Inc., Minneapolis, Minnesota (Cocoa-Max), McCormick Company, Inc., Hunt Valley, Maryland, (McCormick Cocoa Extenders), and National Starch Chemical Corp., Bridgewater, New Jersey (N-Liven Cocoa). A.E. Staley Mfg. Co., Decatur, Illinois, entered the field but quickly dropped out. 

Basinal Brines as a Source of Sulfur in High-Sulfur Coals. Sulfide minerals, such as pyrite and sphalerite, in coal seams may be deposited from basinal hydrothermal fluids. The occurrence of epigenetic sphalerite in Illinois Basin coals has been described by Hatch et al. (119) and Cobb (120). Whelan et al. (121) studied the isotopic composition of pyrite and sphalerite in coal beds from the Illinois Basin and the Forest City Basin, and suggested that some of the coals were affected by Mississippi Valley-type hydrothermal solutions. 

While there are some real problems to be solved which involve residues, insect resistance to insecticides is the really big problem. Curiously, the opponents of pesticides fail to measure it in its full dimensions. Resistance of insects to insecticides is a truly growing problem. As long ago as 1908 the repeated use of lime-sulfur sprays in orchards in Clarkson Valley, Washington, selected out a resistant strain of the San Jose scale, which spread and reached southern Illinois orchards in 1920. Then there followed three species of scale insects...
