Again it should be borne in mind that the Pope was a churchman and wished to abide by the decision of that council in celebrating the festival of Easter, so he drops the ten days and restores the vernal equinox to the 21st of March, its date at the meeting of the Council of Nice in 325, the date by which Easter day was determined. He not only made the correction, but he so reformed the calendar that the solar and the civil year are now made to coincide very nearly. Had he dropped the thirteen days, the vernal equinox would have been restored to the 24th of March, its date in the time of Caesar, and the 24th would still be its date. But the Council of Nice decided that the 21st should be the date by which Easter day should be determined. Hence the reason for dropping the ten days instead of the thirteen is evident; and it is also evident that the Pope acted understandingly when he made the correction in 1582. ERRATA. On 51st page, ninth line from the bottom of the page, instead of 1453 / 43 = 63+, should be 1453 / 4 = 363+. On 76th page, twelfth line from the top of the page, 356 should be 365. THE COLUMBUS CELEBRATION. THE WELLSBORO MAN WHO BROUGHT ABOUT THE CHANGE IN THE DATE. _State Superintendent D. J. Waller, in the School Journal._ Who brought about the change in the date? It was down in the books as October 12th. The Committee of the National Educational Association issued circulars to the country to observe that day. Congress solemnly resolved that that day should be celebrated throughout the land. The Commissioners of the World's Fair fixed upon October 12, as dedication-day, and sent out invitations to the exercises. Suddenly there was a change. Heralded by no newspaper discussion, preceded by no exhaustive treatise, without any authoritative decree, a change was made to October 21. The following facts are indisputable. An aged retired minister in the Methodist Episcopal Church, living in Wellsboro, Tioga County, Pa., author of a little book entitled "Our Calendar," Rev. George Nichols Packer, saw the error. He possessed the confidence of Judge Henry W. Williams, of the Supreme Court of Pennsylvania. After laying the facts before him, he secured through him the approval by the several Justices composing that body, of an effort to change to the proper date, October 21st. Equipped with this approval, he secured the endorsement of his project by Governor Pattison and some of the heads of the Executive departments at Harrisburg. He then went to Washington, gained an audience with the President, laid the subject before the member of Congress from his district, and went before the Congressional Committee.
