New Jersey 



L June 14, 1875. Cranberry prospect apparently reduced fully a fifth. 

 Possible cause, vulcanism (eruption of Vatna Jokull, cited above). 



2. May 12-13, 1878. Frost took nearly half of the cranberry crop prospect. 

 See above. 



3. October 5, 1881. Frost took a third of the entire crop, or two thirds of 

 the berries remaining unpicked when it came. Sunspots abundant. 



4. May and June, 1884. See above. 



5. September 14-15, 1895. Cranberry crop reduced fully a half. Sunspots 

 abundant. 



6. The first two nights in October, 1899. These frosts took probably a third 

 of the cranberry crop. Sunspots few. 



7. May 28-29, 1902. Cranberry prospect reduced more than half. Possible 

 cause, vulcanism (eruption of Pelee, cited above). Sunspots few. 



8. September 21-22 and 22-23, 1904. The frost took about a quarter of the 

 crop. Possible causes, sunspot abundance and vulcanism (see above). 



9. May 20-21, 1905. Nearly a quarter of the crop was lost. Sunspots abun- 

 dant. 



10. September 10-11 and 11-12, 1917. Lowest bog temperature reported 

 22° F. Estimated cranberry loss 25 per cent. Sunspots abundant. 



11. May 27-28, 1927. Lowest bog temperature reported 18° F. Crop pros- 

 pect reduced half. Sunspots abundant. 



12. May 30-31 and May 31-June 1, 1938. Lowest bog temperature reported 

 25° F. Cranberry prospect reduced a quarter. Sunspots very abundant. 



Wisconsin 



1. August 21-22, 1875. Probably half the crop destroyed. This frost prob- 

 ably affected the 1876 crop also. Possible cause, vulcanism (eruption of Vatna 

 Jokull, cited above). 



2. Spring of 1884, probably mostly on May 29. Cranberry prospect reduced 

 fully 80 per cent. See above. 



3. Frosts in August and September and probably on or about June 1, 1889, 

 largely reduced the cranberry crop. The previous calendar year, 1888, was one 

 of the coldest in the northeastern United States in the last seventy years. It was 

 followed by a very remarkable frost in the Middle West and in the South Atlantic 

 and East Gulf States (Alabama and Georgia) on June 1, 1889. A coastal dis- 

 turbance or cloudiness may have saved the eastern cranberry-growing districts 

 from this. The weather sequence here paralleled that of the great frost of June 

 1918, after the cold of 1917. 



4. Frosts in May and especially on August 23-24, 1891, took well over half 

 the crop. Possible cause, vulcanism (eruption of Bogoslof, cited above). This 

 frost reduced the 1892 crop also. 



5. Last four nights of August and first night of September, 1893. Over half 

 the crop destroyed. Sunspots very abundant. 



6. August 20-21, 1895. Frost took at least half the crop. Sunspots abundant. 

 This frost probably aiifected the 1896 crop also. 



7. June 29-30, 1900. Nearly half of the cranberry prospect destroyed. Sun- 

 spots few. 



8. June 10-11 and 11-12, 1903. Cranberry prospect reduced half. Possible 

 cause, vulcanism (eruptions of Pelee, Santa Maria, and Colima, cited above). 

 Sunspots few. 



9. August 7-8, 1904. Lowest bog temperature reported 26° F. Frost took 

 40 per cent of the crop. Possible causes, sunspot abundance and vulcanism 

 (eruptions of Pelee, Santa Maria, and Colima). This frost reduced the 1905 

 crop also (see p. 37). 



10. August 31-September 1 and September 1-2, 1909. Lowest bog tempera- 

 ture reported 15° F. Half the crop taken. Sunspots rather few. 



11. June 7-8, 8-9, and 9-10, 1913. Lowest bog temperature reported 24° F. 

 Cranberry prospect reduced materially. Possible cause, vulcanism (eruption of 

 Katmai, Alaska, June 1912). Sunspots few. 



12. July 18-19, 1929. Lowest bog temperature reported 24° F. Fully a 

 quarter of the cranberry prospect taken. Sunspots abundant.
