131   HISTORIC GROWTH OF MAN.

ONE HOUR EACH DAY.

135

On page 129 is given a watch dial with the normal division and mode of counting. Here we begin counting at what has been called six o'clock in the morning, or sunrise at the vernal equinox. Here is where the astronomers begin to count for the whole year. Starting from this point the hour hand describes the upper half of the dial during the day-time and the lower half during the night-time. It follows the apparent course of the sun for the twenty-four hours. At noon it points upward, at midnight it points downward. At noon is six o'clock; we have been up at work six hours The numbering corresponds to the practical work of life. The numbers from twelve to twenty-four belong to the night-time. A twenty-four hour dial does away with the awkward necessity of writing A. M. or P. M. after any hour, in order to know whether it is an hour of the day or

of the night time.

The dial is divided into periods of six hours by dark-shaded points, and periods of three hours by half-shaded ones, It thus becomes easy to tell the hour by the mere position of the hand, without reading the figures. It is more legible than the older form of dials.

SYSTEMATIC CULTURE is the most

vital and central part of education. Tfiis, too, has been the most neglected or overlooked in the schools of the past. The school should organize th ~ intellectual, the social and the industrial life of the child.
