January 20. Mr. H.'s man says, that he 

 caught this day, in a lane near Hackwood-

 fly, fell from the trees with their wings 

 frozen together by the sleet, that froze as

 dozen so disabled. White. 



MIST, CALLED LONDON SMOKE. 



This is a blue mist which has somewhat 

 the smell of coal-smoke, and as it always 

 comes to us with a N. E. wind, is sup- 

 posed to come from London. It has a 

 strong smell, and is supposed to occasion 

 blights. When such mists appear they are 

 usually followed by dry weather.
