Among the more spectacular accomplishments of this depart- ment may be mentioned the photographing from the air of various varieties of cloud formations. The accompanying illustrations are from photographs made by the writer while acting as observer in a JN-4 (H-S) airplane in one of his trips from Los Angeles to San Diego and as meteorological officer on one of his free flights in spher- ical balloons. As a result of the writer's balloon flights during the Spring and Summer of 1919, it was possible for him to inaugurate daily publica- tion in the Los Angeles weather map of the Weather Bureau and in the local newspapers, tables showing the varying wind direction and velocity at different levels in the air. The United States Army Bal- loon School at Ross Field, Arcadia, generously cooperated in this work by telephoning "wind-aloft" data every morning. These data were used to construct flying charts in that reliable advice could be given aviators and balloonists so that they might take advantage of favoring winds in their air trips. Meteorology is the oldest yet the newest science and its practical application to everyday phases of life, through the medium of one of the largest chambers of commerce in the world, will give it a notable impetus towards practicalizing that Balloon View of the Debris Cone of the Santa Anita Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Southern California Academy of Sciences.
