 great range in temperature, large amount of sunshine, low 

 humidity, deficiency of clouds and a lack of rainfall. 



Unusually low temperatures occurred on the 4th, (5th and 

 17th ; light frosts being reported in some low lands. High 

 temperatures were experienced from the 10th to 15th and 

 from the 22d to 29th ; the last period was the hottest spell 

 of weather felt in Massachusetts for several years. At Prov-

 heat on these days was intense.

 largest ever recorded for any month during the seven years 

 of observation. Very little rain fell in any section of the
