Gifford Pinchot

Gifford Pinchot first met John Muir in 1896, while on a trip through the West to study possible sites for new forest preserves. Pinchot was much impressed by Muir, twenty-seven years his senior, and recalled the meeting fifty years later in his autobiography. He described Muir as “cordial, and a most fascinating talker, I took to him at once.” Muir, in his writings of this period, was explicitly complimentary of Pinchot’s efforts at sustainable forestry. At the Grand Canyon, Muir and Pinchot struck off on their own and “spent an unforgettable day on the rim of the prodigious chasm, letting it soak in.” They came across a tarantula and Muir wouldn’t let Pinchot kill it: “He said it had as much right there as we did.” Within a year, however, Muir had complained bitterly and publicly about Pinchot’s decision to allow grazing in the national forest reserves. This rift between the Moralist (Muir) and the Aggregator (Pinchot) shaped the two wings of the environmental movement, and its original configuration owes much to attitudes developed in the early life and work of each man. Muir entered the University of Wisconsin in 1861, the year the Civil War broke out. Although he was almost twenty-three, his last formal schooling had been interrupted at the age of eleven, when his family emigrated from Scotland. His father, Daniel, a religious zealot, had no use for any book but the Bible. The elder Muir, who joined ever more extreme sects in search of one sufficiently pure and exacting, chose eighty acres of virgin land and put his eldest son John to work clearing it. Days were spent cutting trees and grubbing out roots, and nights were given over to memorizing Scripture. Daniel Muir planted only corn and wheat for cash crops, and the farmland was worn out in only eight years. Choosing a new and larger plot, the family moved and repeated the process. Again, the hardest work fell to John as his father spent all of his time studying the Bible and preaching to anyone who would listen.

The High Voltage Electron Microscope Laboratory at the University of Wisconsin has been in operation a little over one year. I would like to give a progress report about our experience with this new technique. The achievement of good resolution with thick specimens has been mainly exploited so far. A cold stage which will allow us to look at frozen specimens and a hydration stage are now being installed in our microscope. This will soon make it possible to study undehydrated specimens, a particularly exciting application of the high voltage microscope.Some of the problems studied at the Madison facility are: Structure of kinetoplast and flagella in trypanosomes (J. Paulin, U. of Georgia); growth cones of nerve fibers (R. Hannah, U. of Georgia Medical School); spiny dendrites in cerebellum of mouse (Scott and Guillery, Anatomy, U. of Wis.); spindle of baker's yeast (Joan Peterson, Madison) spindle of Haemanthus (A. Bajer, U. of Oregon, Eugene) chromosome structure (Hans Ris, U. of Wisconsin, Madison). Dr. Paulin and Dr. Hanna are reporting their work separately at this meeting and I shall therefore not discuss it here.

Ustilago hordei and Ustilago violacea are yeast-like basidiomycete pathogens ofHordeum vulgare and Silene alba respectively. The mating type system in both species of Ustilago is bipolar, with alleles, A,a, (U.hordei) and a1, a2 (U.violacea) at a single locus. Haploid sporidia maintain the asexual phase by budding, while the sexual phase is initiated by conjugation tube formation between the mating types during budding and conjugation.For observation of budding, sporidia were prepared by culturing the four types on YEG (yeast extract glucose) broth for 24 hours. After centrifugation at 5000g cells were either left unmated or mated in a1/a2,A/a combinations. The sporidia were then mixed 1:1 with 4% agar and the resulting 1mm cubes fixed in 8% gluteraldehyde and post fixed in osmium tetroxide. After dehydration and embedding cubes were thin sectioned with a LKB ultratome and photographed in a Zeiss 9s transmission electron microscope or in an AE1 electron microscope of MK11 1MEV at the High Voltage Electron Microscopy Center of the University of Wisconsin-Madison.
