Show DAY OF FORTY-EIGHT HOURS Fact About Measurement of Time With Which Some May Not Be Thoroughly Familiar. Dr. Willis R Johnson, In his work i on "Mathematical Geography," shows that "portions of three days may exist ex-ist at the same time between 11 :30 o'clock a. m. and 12:30 o'clock p. m., London time. When it is Monday noon j at Irndon Tuesday has begun at Cap 1 Deshuef, but Monday morning has not yet dawned at Attu island. Nearly , half an hour of Sunday still remains : there." What Is known as the "International "In-ternational Date Line" divides the days from one another this being situated sit-uated on the one hundred and eightieth eighti-eth meridian. This runs due north and south, but there are two slight' changes which have been made in it, , ' for the sake of convenience. While a day at any particular place. Is 24 hours long, each day lasts on earth at least 48 hours, Any given day, say Christmas, is first counted, as that day Just west of the date line. The people just west of the date line, who first hailed Christmas have enjoyed en-joyed 12 hours of it when It reaches England; 18 hours of it when It reaches central United States, and 24 hours of It, or a whole day, when it begins in western Alaska, just east of the date line. Christmas, then, has existed 24 hours on the globe, but having just begun in western Alaska, It will tarry 24 hours longer among mankind. Owing, however, to the Irregularity Ir-regularity of the date line, days last more than 49 hours ; in fact, 49 hours, 12 minutes. |
