But this assumption that each heavenly body moves in its path at a uniform rate was soon seen to be contrary to fact. A reference to the almanac will show at once that the Sun's movement is not uniform. Thus for the year 1910-11 the solstices and equinoxes fell as given on the next page: {23} _Epoch Time Interval_ Winter Solstice 1910 Dec. 22 d. 5 h. 12 m. P.M. 89 d. 0 h. 42 m. Spring Equinox 1911 Mar. 21 " 5 " 54 " P.M. 92 " 19 " 41 " Summer Solstice 191l June 22 " 1 " 35 " P.M. 93 " 14 " 43 " Autumn Equinox 1911 Sept. 24 " 4 " 18 " A.M. 89 " 18 " 36 " Winter Solstice 1911 Dec. 22 " 10 " 54 " P.M. so that the winter half of the year is shorter than the summer half; the Sun moves more quickly over the half of its orbit which is south of the equator than over the half which is north of it. The motion of the Moon is more irregular still, as we can see by taking out from the almanac the times of new and full moon: _New Moon Interval to Full Moon_ Dec. 1910 1 d. 9 h. 10.7 m. P.M. 14 d. 13 h. 54.4 m.
