Probable Weather for Apeil, 1865.— The forecast for last month was 

 especially deflective in promising " settled and fine weather," from the 16th to the 

 end, as it was about the 16th that the strong gales from the east, and very severe 

 frost, commenced, lasting to the 24th, when the wind went back to the west, and 

 rain followed. Next month, fine and settled for the first ten days, thence to the 15th 

 or 18th, frequent changes, with gales, driving rains, and occasional frosts. From 18th 

 to 25th, cold and dry, barometer high, wind easterly ; 26th to the end, genial, sunny 

 and settled.
