Disturbances originating iu the Catskill and adjacent mountains 

 usually move across or down the lower Hudson valley, which is 

 therefo're a region of great storm frequency; and similarly the 

 stoirms of the eastern Adirondacks often pass to the St. Lawrence 

 valley. The whole of the interior of the Adirondack region, with 

 its high mountains and numerous streams and lakes, also appears 

 very favorable for the development of thundersttoirms, although a 

 suflQcient number of observations are still lacking. 



Snowfall.

 whole, and only the most general facts relating to the subject 

 can be given here. 



The following measurements of the total depth of snow falling 

 each month during the three past winters are derived from the 

 repoTt of the New York Meteorological Bureau.
