The Weather. 



Spring opened very favorably for the farmer, and the 

 warm, dry weather of the first half of May enabled him to get 

 his planting done in good shape. Rain set in the morning 

 of the twentieth, and it has fallen more or less nearly every 

 day since. Slight frosts occurred on the nights of the 

 20th, 27th, 2<Sth and 29th, but scarcely any damage was 

 done. Through the kindness of the director of the Hatch 

 Experiment Station of the Massachusetts Agricultural Col- 

 lege, we are enabled to print the summary of the Meteoro- 

 logical Observatory at Amherst for the month of May.
