 By estimating the area thai one could 

 see over the earth, he would he sur- 

 prised that no less than fifteen to 

 twenty millions of shooting- stars reach 

 the earth every twenty-four hours. 



At times more than the average 

 number of shooting stars may be seen, 



showers oi '33 and '66 was that millions 

 of small lx>dirs arc grouped together, 

 moving in an orhit like a planet or a 

 comet about the sun as the center of 

 up 'lion. Each year in November the 

 earth in its journey about the sun goes 

 through the track of the meteors, hut 

 only once in thirty-three years are the 

 meteors encountered in sufficient

Though not so numerous as in these 

 two years, there is each year in August 

 quite a number of meteors, and during 

 the first half of the month, there can 

 readily be counted between ten and 

 twenty every hour. The reason for the 



numbers to give the fine display ot a 

 shower. In other words, it takes them 

 thirty-three years to revolve about the 

 sun. 



The cause of the August shower is 

 si miliar to that of the November 

 shower, but with an important differ-

 shower are not so much bunched as
