Long Island Sound. 1937-1961. with the exception of 1('0(), setting during all these years extended into September. In four of these years setting continued almost until the end of September and. on one occasion, actually occurred on ( )ctober 1. Taking the ten poorest years, ranking from H>th to 25th, only in one year, 1945, did setting extend beyond the first week in September. However, in that unusual case setting began and ended on September 11. In some poor years, as in 194(>, setting ended mi July _'.\ while during another poor year, 1950. it ended on August 7. 'I bus. in general, during the years of heavy setting, starfish continued to set later in the season than during the years of light setting. I b-av\ sets tend to be of long duration, while poor sets tend to be short. Dur- ing the nine years of heavy sets the setting period ranged from 58 to 91 days. averaging about 74 days i'he length of the period during the ten poorest years. however, ranged from 1 to o/ s and averaged only about 40 days. \ setting which reached a maximum, or peak, early in the season may end early or fairly late, while a setting that reached a maximum late tends to end late in the season.
