Late soivn Clover*. 



T 



AN 1804, the war having deranged the usual course of 

 agriculture in Saxony, a fanner, Mr. Thaer, was unable to 

 sow his oats and clover before July. The first mowing of 

 the clover was a very slight crop ; but the second was as fine 

 and thick as possible. Mr. Thaer has since repeated the 

 experiment, and he has found, that clover, when sown 

 later than ordinary, grows more abundantly, and of better 

 quality; and that, provided it be sown before the middle of 

 August, it will certainly succeed.

 of the first thunderstorm, the lightning was conducted 

 down the rod, and split the rock into several pieces, without 

 displacing it.
