yellowish, though as it is the Ii ght of
 our day. it is for us truly white, only
 yellowish by comparison with such light
 as we get at night and in small quan-
 ties from Sirius, Vega, and Alta r,
 and their fellows. But the light
 actually emitted by the glowing mass
 of our sun is not only not yellowish, it
 is violet. It has been shown by Prof. Langley that if the atmosphere of the snn could be stripped of, he would
 shine as violet sun,-though of course
 Tn very few minutes our eyes would
 become accustomed to the change, and
 he would appear white as before. Then
 if his atmosphere came back suddenly,
 he would appear for a few minutes
 brilliantly red, because our eyes would
 have become accustomed 10 regard the
 violet light as white, but after that we
 should see him as we see him now.
 It is when with, telescopic eye we
 turn from the single suns to those
 which travel in pairs, or in sets of three,
 four. or more. that we find the strong
 est and most beautiful colors, the great
 est variety of tint, and also combina-
 tions of colors charmingly contrasted.
 We find, perhaps, splendid white star
 with a small companion of a deep red
 color, or purple, or vermillion, or dark
 blue. A large yellow star may have
 small companion colored purple, or
 blue, or ruby red. A brilliant orange
 star will be seen with small violet or
 blue or emerald-green companion;
 red star may have beside it green or
 blue companion. e
 Yet it must not be suppos ed that all
 double stars show contrasts of this kind. Among them we find pairs of the same color. or of colors not differing more than as white differs from pale yellow,
 or red from ruddy' orange. or golden yellow from orange yellow. Moreover, in many cases both stars of ra'r are of 'he same or very nearly the same
 brig gness, as we'll as of the same or very nearly the same color. With a telescope of fair strength the colored pairs numbered l, 2, 3 and 1 may be easily seen. The two numbered 3 and 4 require a better telescope and more practice in looking at these objects than the first two. A better telescope stlll is required to see the pair numbered ,; and to see (which is the same as ? as a triple star-that is, to see the small green star with fairly good telescope, divided into two very small stars, one yellow, the other blue-requires very good telescope indeed.
 There are few pleasanter ways of using a telescope, espec ally one of fairly good power than in turning it on double stars. Lists of the most inter- esting of these objects are given in works on astronomy, and a very lit tie practice will enable the young observer to recognize these stars in their several consultations, and turning the telescope on them, to note their dis tance apart, their colors, and their ap- pearance generally. It has been found that the cOlors of the double stars are due to the vaporous atmospheres which surround these orbs! In other words, their cOlors may be compared to those seen in railway signaling, where the light itself is white, but appears colored because of the action of colored glass; only in the case of the double stars there are not red, green or blue glasses. but colored vapors.
 But how can we'P pass from the consid- eration of these beautiful colored suns: without allowing our minds little play of fancy? It Is reasonable to be- lieve that other suns than ours have, like ours, their attendant worlds, that every one, think, must consider there are worlds travelling around the beauti- ful orange sun Alb:reo,. and others travelling around. it's blue companion sun. To both sets of worlds, Albireo and its companion must alike be suns According to the position of one of these worlds at any time, the orange or the blue sun may be the chief light-bringer or in some cases.both may for a while supply equal quantities of light. But now consider what'strange effects must result from the crcumstance that there will generally be two sorts of day.
 From sunrise to sunset of the orange sun there is day which, were that the only sun, would simply be such day as we have, for onl y whiteness would be From sunrise to sunset of the blue sun there is day, too. If both suns chance to rise and set at about the same time, their combined light gives a splend d white day; yet even this must 1iffer from our day very remarkably, for instead of single set of shadows such as we have, there would be three 1;stinct kinds of shadow-namely CD, where no light falls from the orange sun, or blue shadow> (2) where no light ialls from the blue sun, or orange shadow; and (3) where no light falls rom either, or shadow such as we have. The combination of these several tints n landscapes, clouds, forests, features of animals Gncltlling any races akin to nan) and so forth, and the ever-varying. j play of color, must be very strange and very beautiful.
 But consider, also, the strange effects lat least to our minds, accustomed only O one sort of day) which must result 1 when the orange day and the blue day ,egin and end at different times. For quarter of a day of our ime-we may imagine-the orange sun. 'ules; then the blue sun rises, tints' change, var;egated shading replaces or iinary shadows, and tn lasts for an- other quarter of day of our time; then he orange sun sets, and the blue sun, jules supreme; lastly the blue sun sets; md, for short time-that is, till the orange sun rises-there is night, though still there must be much twilight, and wilight tints of singularly varied and fartng hues. As flor the gloFies of ;unset and sunrise, who can imagine heir complicated beauty?
 All this may seem fanciful, for indeed we not only do not know, we can never
