742 TABLE 842A.— ECLIPSES OF THE SUN 



The diagram, figure 31, prepared by the U. S. Naval Observatory, shows the paths of total 

 and total-annular eclipses in the United States during the twentieth century. The following 

 data for total United States solar eclipses between 1950 and 2000 are taken from the complete 

 table of eclipses from A.D. 1900-A.D. 2000, given by D. H. Menzel. 202
