WHAT WE LOOK LIKE FROM THE MOON

Seen from the moon, which gravitates around 01 at the mean distance of 240,000 mtlei| the earth appears four times greater In diameter and thirteen timei wider In surface, and, consequently, more luminous than oo'r latellite doei to as. Immovable In the black depths ef celestial space, she leara with majesty, seeming to reign over bnmao destinies, and shows phases analogous to those exhibited m the moon, bat m Inverse order. When the son covers with his rays the terrestrial hemisphere that faces the moon, the latter Is new, aod the fall earth Is shining In the sky, while at the moment of the fall moon it Is the non-illuminated half of oar globe that is turned toward this neighboring world ; the earth is then nesr. To] the first lunar quarter corresponds the last terrestrial quarter, and to the first quarter of the earth the last quarter of the > moon. The lanar day, the period during whioh our satellite successively presents every portion of her snrfaoe to the solar raya, and consequently makes one revolution upop her axis, equals twenty-nine days twelve boors, and forty-f oar minutes. During this long diurnal period the earth offeri Us first quarter at sunset and it last at sunrise. So the ''eartblight" contributes muoh more to the illumination of the lunar nights than the moonlight does to the illuminating of onrnights, and theselenites have tru'y more reasons for believing that the earth exists for the sole purpose of dissipating the darkness of their nights than we have for considering the moon as created to be the torph of terrestrial nights. Our planet Is afterward visible, amid the stars, and despite the sub's presence, under the form of a large orescent, which gradua'ly diminishes m width until it entirely disappears at the moment of the new earth, The daily rotation of the earth upon its axis fprma a very attractive spectacle. Varied spots mark our continents and seas, over which move vast bands of clouds. Two white caps cover the poles. The oceans have a bluish green color and appear darker than the land The contour of the disc, more luminous than the inner part, Is slightly reddish under the influence of stmospheric refraction. Europe and Africa, Asia and the India fiea, the F cific, the two Amerloai, and the Atlantic di file In tim every twenty-four hour*. The earth thus forms a marvellous oaleatlal dock that may be consulted by bnt a glance at the heavens, and to which the succfuion of the terrestrial phases adds another base for the measurement of time. Seen from the centre of the visible hemisphere of the moon, the earth hovers always In the cenltb. In measure as an advance is made toward the edges of the disc, oar globe appears to descend progressively, and, from the drcamfereoee of the lanar hemisphere, it Is observed to oso'llfte at the horizon. In the oourse of the long lunar night of 3J54 boors, which forms half of the diurnal period and succeeds daylight, the earth soars majestically In the heavens, undergoing her phases from the first to the last quarter, and at midnight ihtnes with Intense light fourteen times stronger than that of the full moon. With so strong a light do we illuminate that psrt of our satellite which is dark at the epoch that it becomes visible from here, owing to the reflection of the • terrestrial rays from Its surfsoe Thfs reHeotlon of a reflection is styled ashen light. , The earth, an enormous globe of ever > varied espeat, stwpendpd at a fixed point i of space, therefore presents to the yeleplte* • charming spectacle; The Inhabitant* of the Invisible hemisphere of the moon, where oar globe Is unknown, h»ya to take a long voyage In order, from tha lunar face tnrned towards us, to contemplate that magnificent star wbloh we call tb# as rtb, and whioh op there must bear names that express** »J! the admiration « Ibtl ibi iQiptif i,
