from 1851-55 and from 18(38-91. The next lowest mean 

 was 69.8^ in 1884. The highest July mean at that station 

 was 77.6° in 1876. At Fitchburg,. where there is a series 

 of observations beginning in 1857, the years 1860, 1865 and 

 1884 only show a July mean lower than the present, the 

 lowest being 6Q.i^° in 1860, just one degree lower than in 

 1891. The highest mean at that station was 74.4° in 1870. 

 The records at the Weather Service office in Boston show- 

 lower July means in 1881, 1884 and 1888, the lowest being 

 in 1884 and also just one degree lower than in 1891. The 

 warmest July at Boston, in the twenty-one years of obser- 

 vations, was in 1872, when the mean for the month was 74.7°. 

 At Thompsop, Conn., where observations for nearly half a 

 century have been made, and with a thermometer that has 

 hung in nearly the same position during all that time, the 

 mean was the lowest, with one exception, ever recorded. 

 That was in 1859, when the mean was 64 9°, less than one- 

 half degree lower than in 1891. 



The precipitation was generally heaviest and the number 

 of rainy days greatest in the Connecticut valley, while the 

 least precipitation fell over that section between the Connecti- 

 cut valley and the coast region. Thunder-storms were not 

 frequent or unusually severe. Hail fell at Cheshire on the 

 20th, during the progress of a thunder-storm, doing some 

 damage to tobacco. At Spring6eld, on the 25th, during a 

 heavy thunder-storm 0.85 inches of rain fell in fifteen minutes. 

 It was accompanied by high winds along the south-central 

 part of the State. At Dudley, there were three distinct 

 thunder-storms during the afternoon of that date. The sea 

 breeze was frequent and Avell marked along the coast.
