Excerpt from Report of the Secretary of the Smithsonian Institution and Financial Report of the Executive Committee of the Board of Regents, for the Year Ended June 30, 1936 Astrophysical 0bservatory. - Measurements of the solar constant of radiation have been continued on every possible day at the three Smithsonian stations at Table Mountain, Calif, Montezuma, Chile, and Mount St. Katherine, Egypt. The irregularity of the results at Table Mountain led to the development of a criterion for distinguish ing unfavorable sky conditions, which will provide a new increase in the accuracy of measurement of the solar variability. Two papers published by Dr. Abbot appear to prove that the short-interval changes of solar radiation are Of major influence on the weather for the ensuing 2 weeks or more. TO test the use of this relationship in weather forecasting, seven additional Observing stations are required. An amendment to the Urgent Deficiency Act providing the necessary funds was passed by the Senate, but was rejected in conference with the Ho'use. Preliminary studies were begun of the possibility of automatic determination of solar variability from sounding balloons. Division of Radiation and Organisms - The Division's investiga tions comprised the following: Continuation of work on the depend ence of carbon dioxide assimilation in wheat upon the wave length of radiation; experiments on the effects of ultraviolet rays on algae; experiments on the effects of light of different wave lengths on growth of tomatoes; development of an extremely sensitive and quick-acting spectroscopic method for measuring carbon dioxide con centration; study of the dependence of photosynthesis in wheat on time factors; and the development of a highly sensitive thermo couple Of great ruggedness.
