low from this that the earth re- vOived upon its axis at that time. To rthat 1t was necessary for 1t to do % in order that 1t might be lighted and warmed on all sides.
 Before the glacial period began 1 the solar system was young. and 1t was not nearly as great then as It is now. Size, and high orbital velo- 1 city are signs of age in solar sys;, tems. When solar systems arc great and contain orbital velocities of one hundred or more miles per second. their ages are measured by periods of time too great to be named.
 Before the glacial period began. and when the solar system was young and the earth was still young CT, the sun revolved about another great sun 50 that the planets of the solar system received light and warmth on all sides whether they revoIved upon their axies oftener than they made an orbital revolution about the sun or not. This story in itself is a long story and space will not permit going into details at the | present time.
 | The moon was the nucleus of q rather large comet that came near ! enough to the earth so that the mutual gravitational force was strong enough to hold them together i It is well known to astronomers that body like the earth could capture and hold l body like the moon. that ! might come near it. if the velocity and distance happened to be right. | When the moon was first cap- , tured by the earth it revolved much nearer the cayth than now and its i velocity was much greater than i now, When these satellites are first ! captured they lose a great deal or ! their velocity by ipparting their en- rgy 10 the system to cause It to re- , yolve. as I am about to explain; but i after thts they are slowly accelerated in their orbital yeloci,ies, as the secular acceIeration of the moon i plainly shows.
 VI ,d bv the earth it's revolution about the earth caused the resisting celes- tal medium near the earth 10 revolve, and this re- volving medium acting upon the upper atmosphere of the earth caused the whole earth to re. rolye. very slowly at first, but very rapidly before many years had pass ' cd.
 ! No heavenly body revolves upon it's axis oftener than it revolves al out a primary unless it has one or more satellites revolving about it, because it is the revolution of the satellite, or satellites. about the body that caused the aerial revolution. Unless a body is revolving very rapidly. the newly captured satellite { always makes an orbital revolution in less time than the primary makes an aXial revolution. Mars revolves upon it's axis once in about twenty four hours: but the small inner sat 1 elite makes more than three orb1tal i reNOlutlOl1S Tn lnlS tlIle. u 'S pld III that as time is measured in these things. this Is new satellite. The inner ring of Saurn makes an orbitaI revolution in less time than Saturn makes an axial revolution; therefore this ring is a recent acqui- sition.
 Mars has two moons while the earth has only one. The moons Of
 Mars are only six or seven miles ln
 diameter, while our own moon has
 a diameter of more than two thou
 sand miles. This is why the equn.
 torial surface velocity of the earth
 resulting from axial rotation. is SC
 much greater than that of Mars
 Jupiter and Saturn are between
 seventy-three and eighty-eight thou
 sand miles in diameter: and vel
 Jupiter makes an axial revolution in
 little less than ten hours, while
 Saturn requires a little more thar
 two hours for one revolution. Thi:
 is because these planets have cap
 turad eight or ten rather large sat | ,4llitaa
