ALLISON — NOVA SCOTIAN METEOEOLOGY. 



the 25th. Here the direction was N. and N.NE. with thunder, 

 lightning, and over 2.5 inches of rain in 22 hours. 



Taking up the wind average forces of the months we find 

 January a trifle above the year's normal. February still a little 

 higher. March getting up to the maximum of 11.35. April falls 

 off very much, and May remains much the same as its predecessor. 

 But June shews a mean still less. July and August are far the 

 most quiet months, the former giving an average of only 4.86, the 

 latter the minimum of 4.69. September returns to near the' 

 mean of June. October increases a little more, while November 

 approaches very near to March. In these two months the general 

 force of wind is much the greatest. December has an average 

 about equal to January. 



Our Peninsular position, equal Barometric distribution, and level 

 surface of country, divert many violent gales from this Province, 

 and we cannot be too thankful that, as one of the most quiet spots 

 of North America, we thus enjoy the most favourable facilities for 

 the production of the land crops peculiar to the Latitude, and safety 

 on our sea coast, compared with other shores of the Atlantic. Even 

 iin a station so far inland as Toronto the mean velocity is very much 

 the same as our own. 30 miles an hour is the minimum of a gale, 

 and in 1876 there were 20 gales; in 1875, 19; in 1874, 18; in 

 1873, 17; in 1872, 26, and in 1871, 26; of these 126 gales, 103 

 took place between October and March, inclusive. It is very rare 

 to reach 30 miles per hour in May, June, July, or August, though 

 the two heaviest gales, as recorded above, occurred in this latter 

 month. In total precipitation both the rain and the water 

 obtained from snow when melted, are included. The dry snow is 

 first measured on a platform, and has been found to give on an 

 average one-tenth of its depth in water. Thus one inch of level 

 dry snow gives .100 of water over the same superficial area. Occa- 

 sional the equivalent of 1 inch of snow varies from .090 to .110 

 of water, but one-tenth is quite near enough for an average. In 

 Great Britain 1 inch of snow rarely measures over .090 of water, 

 as the flakes generally lie much more loosely, and occupy more 

 space than here.
