Because of the "unbelievable" preservation of the specimen found in Illinois, a club moss cone over two hundred million years old, located in Carboniferous rock in Grundy County, scientists may have a new test for the hypothesis that the world's underground stores of petroleum derive from plant life, Darrah said...
...important discoveries were reported by the Department of Biology during the summer. On the Illinois prairies William C. Darrah, instructor in Biology, discovered "the most perfect plant fossil over found," and in the trackless forests of the Pico del Yaque Mountains in the Dominican Republic. Dr. Phillip J. Darlington, assistant curator of insects in the Museum of Comparative Zoology, found many new species of insects, worms, and reptiles, hitherto unknown to science...
Main approach to the problem of utilization of solar energy has been study of green plants, which in their own simple and mysterious way utilize the energy of sunlight to convert carbon dioxide and water into food. Chief agent in this process of photosynthesis is chlorophyll, the green coloring-matter in leaves, which acts as a catalyst, speeding up the transformation, but undergoing no conversion itself. Since chlorophyll is not effective as a catalyst when extracted from the plant, chemists have been unable to study its action. It is composed of two separate pigments, blue-green chlorophyll A and yellow...
...Queen's Ware" for George Ill's Charlotte), was respected for improving turnpike roads, founding schools and chapels, was hated for espousing the cause of the upstart American colonies. Bit by bit the Wedgwoods disposed of their land, until a bare five-acre plot on which the plant still stands was jostled by other potteries, mines, factories.

Thus the Electric Power Board of Chattanooga offered to buy the Chattanooga property of Mr. Willkie's Tennessee Electric Power Co., threatened to build its own plant unless he agreed. Last week, in a long letter to the board, Mr. Willkie deftly left the matter hanging, wound up with a pious hope: that the New Deal's "free gift of 45% of the cost of Chattanooga's proposed power system will not be used...
