Thomas Templeman, aeronautical instrument expert at the Bureau of Standards, is shown inside of the steel cell, the interior of which is designed to duplicate conditions in the upper atmosphere. The changes of atmospheric conditions can be regulated by the "pilot" and the cylinder is also used to test instruments used in altitude flights

Some forms of animal and plant life probably exist on Mars, is the conclusion of Dr. W. W. Campbell, president of the University of California and a director of Lick Observatory shown at the telescope. He is regarded as one of the world's foremost astronomers. Dr. Campbell bases his conclusions on the fact that studies of the ruby planet, now but 42,000,000 miles distant, show that there are indications of vegetation there. The fact that the surface of Mars takes on a dark hue in spring and a lighter color in the fall, comparable to seasonal changes on earth, indicates to Dr. Campbell that there is a strong possibility of plant and animal life there. Two factors necessary for the existence of life, he explains, are the presence of water vapor and oxygen.
Almost conclusive evidence of the presence of these two vapors is seen in the findings of Dr. W. H. Wright of Licks observatory, who has made many investigations of the Martian atmosphere.
