20 PROCEEDINGS OF THE AMERICAN ACADEMY 



June 9-15, During the first three days of this period, the morning 

 weather maps show that an area of high pressure came from the 

 northwest, and crossed New England; as its centre lay off our coast, 

 an area of low pressure stood in Colorado. From the 11th to the 

 15th, this low pressure centre moved along the usual east-northeast 

 path, and ran down the northern slope of the St. Lawrence valley ; 

 during the latter part of its passage, there were three scattered reports 

 of distant lightning in the evening of the 14th after a warm day 

 (mean max. 84°). On the 15th, the day opened with low pressure 

 centres in Newfoundland and Lake Superior, and high pressure off 

 the Carolinas ; it was probably within the circuit of the Western 

 area of low pressure that two local storms occurred, one in Maine in 

 the afternoon, the other in Connecticut in the evening of this day. 

 They brought us only three reports, in spite of the rather high temper- 

 ature, and the not great distance of the low pressure area. 



June 16. Several small showers occurred in southern New Eng- 

 land while the second of the above-mentioned low pressure areas 

 hesitated in the Gulf of St. Lawrence on the hot afternoon and even- 

 ing of the 16th (mean max. 88°). The most interesting of these 

 was a well-developed storm of small size that was felt a little after 

 14*' over the northern part of Rhode Island, and moved eastward 

 to Cape Cod Bay. It was unfortunate in selecting a district poorly 

 represented by our volunteers, and thus lost the opportunity of being 

 carefully portrayed. It arose in northeastern Connecticut, and moved 

 eastward across northern Rhode Island and southeastern Massachu- 

 setts at a rate of about 35 miles an hour. The clouds were heavy, 

 but the rain-fall was generally moderate ; the temperature fell from 

 90° or 95°, as it had been shortly after noon, to 80° or 75°, and rose 

 again a little after the storm moved past ; the wind showed a distinct 

 control by the storm, as a brief gust of moderate strength was felt at 

 most of the stations jnst before or during the rain, the direction of its 

 blowing being in all cases away from the centre of the rain area. On 

 reaching Taunton, the rain had become very light ; and no report of 

 the storm came from Plymouth or Provincetown. Jewett City, 

 Conn., Crompton, R. I., Fall River and East Freetown, Mass., saw 

 the storm passing to the north ; and Medfield and Pembroke, Mass., 

 reported it to the south, about the time another storm was passino- 

 to the north. This second storm formed not far north of the first 

 one, at a little later hour, and passed over Blue Hill on its way to 

 the south shore of the Bay. The rain was reported heavy only on 

 Blue Hill, where the wind was strong for a time during the shower.
