"Not even the Governor himself could parade unless he were Indian" (pages 302-03). Flagstaff is a busy intellectual center-the home of Arizona State College, the distinguished Museum of Northern Arizona, an important Naval observatory, and Lowell Observatory. The astronomers flourish under the same conditions-an altitude of 7,246 feet, dust- and pollen-free air-that attract sufferers from pulmonary disease to Flagstaff. Lowell Observatory is famous for its "firsts," nota bly for determining the temperatures of Venus, Mars, Jupiter, and Saturn, and for discoveries that led to the theory of the expanding universe (page 325). But the most dramatic of the observatory's efforts was the prediction of the existence of Pluto and its subsequent discovery. In 1902, Percival Lowell, found er of the observatory, reasoned there should be another planet beyond Neptune. Astronomers worked for years to complete the mathematical proof, and in 1930 Pluto was caught on the photographic plates by astronomer Clyde Tombaugh. Lowell did not live to see it.
