KANSAS CITY REVIEW OF SCIENCE. 



minimum temperature on the 9th being 47 °. From this time, the 7th, to the 20, there 

 have several slight showers, the most abundant being that of the 20th. On the 16th 

 the temperature rose to 82°. The prevailing winds have been northwest and 

 north. The total, rainfall, 0.435 inches, is even less than that recorded last month ; 

 but this record closes with a rain storm in progress, which may betoken the be- 

 ginning of our spring rains. This is nearly a month earlier than they began last 

 year, and the wheat which had begun to suffer will be greatly benefited thereby. 

 The first dog-tooth violets (erythroiiiiim albiduiri) were seen here April 9th. Elms 

 and maples began to blossom about the same time, and cottonwoods a few days 

 later ; redbuds did not begin to open till the 20th. There was a slight snow 

 squall on the 12th, and the night following the temperature sank to 16°. The 

 wind has continued mostly from the north and northwest, and the highest velocity 

 recorded was 58 miles per hour on April ist. 



The following summary by decades represents the averages as determined 

 from our tri-daily observations : 



Highest barometer, 29.27 on the 26th of March. 



Lowest barometer, 28.50 on the 7th of April. 



Highest temperature, 83° F. on the 17th of April.
