(Astronomical calculations, tables, etc., made expressly for THE TRIBUNE ALMANAC by Berlin H. Wright, Penn Yan, N. Y.) There will be five eclipses this year-two of the moon and three of the sun. I. A total eclipse of the moon March 10, visible in North and South America, Europe and Western Asia. (See table below.) On March 22, 1913, this eclipse returns again, and will be seen on the west coast of America and in Asia. II. A partial eclipse of the sun March 26, of 4 digits, not visible in the United States; visible in Arctic America and N. E. of Hudson's Bay, Greenland, England, and the Northern Pacific Ocean. This eclipse returns again April 6, 1913, and will then be seen in British America and Alaska. III. A partial eclipse of the sun August 20, of 3 1-5 digits, invisible in North or South America; visible in N. W. Asia and N. E. Europe. It returns again August 31, 13, but smaller, and will be seen in Greenland and the eastern part of British AmerIV. A total eclipse of the moon September 3 and 4, visible in North and South merica, Western Europe and Africa. (See table below.) This eclipse returns again eptember 15, 1913, and will be seen on the western coast of America (the moon setting while eclipsed), also in Asia. V. A partial eclipse of the sun September 18, of nearly 9 digits; visible in the South Pacific Ocean and Northern Australia. It returns again September 29, 1913, Jarger, and will be seen in the South Pacific Ocean and in New-Zealand. TO FIND THE TIME OF GREATEST ELONGATION OF POLARIS. By adding the numbers in the annexed table for any given latitude to the time of meridian passage of Polaris (the Pole Star), given in another table, the time of its greatest western elongation is found. If the same number be subtracted instead of added, we get the time of greatest eastern elongation. At the time of either elongation the magnetic Constant bearing may be taken with for the compass, using that Elonga elongation which occurs at tion. night. The eastern elongations occur at night from April 1 to October 11, and (the western elongations occur at night all the rest of the year. Correct local time is to be used, and bearings taken on the star promptly on time; but an error of 5:54:20 half a minute or even a H. M. S 5:54:10 EMBER DAYS. First Sunday in Lent. September 14.
