During the first part of the month the weather was cold 

 and stormy, and on the night of the 4th the thermometer 

 fell to 8° below the freezing point, so that many plant 

 which the fine weather of the preceding month had brought 

 forward, were either killed or much injured by it. Nearly 

 all the flowers of the Glycine sinensis were killed although 

 the plant was covered with a screen of thin canvas. On 

 the 7 th there was much lightning, and on the 12th some 

 thunder with a heavy shower of hail. The nights of the 

 21st and 23rd, and the morning of the 24th were very 

 boisterous and stormy.
