WEATHER IN CRANBERRY CULTURE

a general weather situation favoring convergence of warm moist air over southern 

 New England, and a definite thrust of cold air from the north; these conditions 

 obtaining when diurnal heating produces strong local convection to combine 

 with the favoring general conditions to produce powerful convection into cold air 

 aloft.

The following are the more important hailstorms recorded as occurring in the 

 history of the Massachusetts cranberry industry: 



1. July 17, 1889. This was a widespread storm in eastern Massachusetts, 

 hail falling in large quantity in many localities both north and south of Boston. 

 It was the severest hailstorm in the history of Lynn; nothing equal to it had been 

 seen in Milton in forty years; and at Nahant the largest hailstones were 2J^ inches 

 in diameter. The storm came a little before 2 o'clock in the afternoon and lasted 

 about 20 minutes. Cranberry bogs were hurt quite generally throughout Ply- 

 mouth County (except in Plymouth) but mostly in Carver and Wareham, with 

 an estimated reduction in the crop prospect of 20,000 to 26,000 barrels. The 

 storm was destructive as far east as Sandwich where some of the hailstones weighed 

 3 to 4 ounces. 



2. June 22, 1904. It was estimated that the hail reduced the cranberry crop 

 prospect by from 50,000 to 75,000 barrels, and probably had an adverse effect 

 on the 1905 crop also. The vines were so badly damaged on one bog in Wareham 

 that it had to be replanted. Hail fell in Middleboro, Plympton, and Hanson and 

 formed a deposit 6 inches deep in Pembroke. It skipped Carver. It was severe 

 in Sandwich, Sagamore, Bourne, Buzzard's Bay, Wareham, and the western 

 edge of Plymouth, accumulating to a depth of 4 inches at White Island. Ice 

 remained on the ground the next morning at both Pembroke and White Island.
