The Starry Skies m November
By PROFESSOR BARTON. of the University of PennsyIvani

In August the milky way eNteHu .h . across the sky through the zenith in nearly north and ssuth direction. Since that time it has seemed to turn about he zenith as or a pi~ot the south end moving toward the west until now 1t lies in a direction which is nearly east and west This motion continues until February. when the direction is again north and south. After this time the milky way leaves the zenith and lies near the horizon until August The great square in Pegasus lies high in the sky south of the zenith and Cassiopeia north Of the zenith. Cygnus, the north ern cross. now stands in it's natural up- right position in the west. Orion, the prince of winter consultations, is now on the eastern horizon, as shown on the map.
 The only eclipse of the sun visible in the United States this year occurs on November 10. No part of any other eclipse of the sun will be visible in the United States until 1923. This is a par tial eclipse. The moon being in the light of the sun, casts a great conical shadow. When this shadow strikes the earth those within the shadow have a total eclipse and those near the shadow who receive some but not all of the light of the sun have a partial eclipse. If~any part of the earth is in the shadow the eclipse is called total. In this case the moon is north of the sun when they pass so much that the shadow cone does not touch the earth at all so that no one has q total eclipse, but the shadow comes close enough to bring a part of the earth in the region from which Of iorbf ic rl1t Off people see a partial eclipse of the sun The point of the earth which comes nearest to the center of the shadow and thus has the largest partial eclipse is point on the Atlantic ocean. There about three-quarters of the suns diam- eter will be concealed. At Orono Maine 0H of the diameter is hidden, which is about the largest amount for any place in the United States. Figure shows the parts of the earth which will see the eclipse Within those parts inclosed in the loops the sun is near rising Cleft loop or near setting fright loop), while the eclipse is in progress, hence the whole eclipse is not seen from these places.
 The time at which an eclipse of the sun begins or ends and the magnitude and appearance of the eclipse is differ ent at each place SO that it is not pos. sible to, give picture of conditions
 
 done in an eclipse of the moon. Figure shows the parts of the United States from which the eclipse can be seen. It will be seen that some of the states in the west and south will not see the eclipse at all. On this map lines are drawn marked 10, 20 90 and 40. These represent the places where this percent age of the suns diameter is covered by the moon Other lines marked S.30 $40, etc, show the places where the middle of the eclipse occur at the given central standard time. If the place uses eastern standard time an hour should be added; if mountain standard time an hour should be subtracted. The time and magnitude of the eclipse at places not on the lines can be estimated from the distance of the places from the two lines between which they lie. In all cases it is the northern part of the sun which is hidden.
 The eclipse is naturally more inter- esting in those places in which the eclipse is largest. This occurs in the middle and New England states. Phil adelphia lies on the line which shows that 90 per cent of the suns diameter will be hidden and Figure 8 shows that the maximum eclipse occurs at S.55 cen- tral or g 55 eastern standard time.
 Figure shows the appearance of the sun at eight times, from the flrst contact which occurs at S.5S until the last contact at 1117. These drawings represent the conditions approximate ly for places at a considerable Gis- tance from Philadelphia such as New York or Baltimore.
 The eclipse may be watched through smoked or colored glass for the sun may be made to shine through a small hole and it's image viewed on a white background, such as {. piece of paper, olaeed behind the ho's

 JnAs as t:." ese@ses ovtI ,he sun and eclipse s1 ',s snonu a SO passes over stars a4.a eS sp.s theIH S.cults them, as astron5me1 c&n it. EaIly on the morning of November ? he -.aoon passes over the bright star cpica As appears at 5:12 a. m. and reappears at 6:35. This would be very interesting occultation by reason of the brightness of the star occulted if it~occurred at a more convenient time and if the star were not so close to the horizon when occulted.
 sOn November 16 the star Beta Capri- semi is occulted. AS seen from Wash eNBton it disappears at 4:s7 a. m.. and SSAppears at 5:5S D. m. The star is well up in the sky when the occultation oc- CUTS. Daylight will interfere with the view of the disappearance. The star is of 3.2 magnitude. Opera glasses or telescope will be needed for satisfac- ,
