It will be seen that on January 12, 1909, practically all the buds 

 were killed except on the most hardy varieties by a temperature 

 of -11 F. In fact fewer peaches were borne at Columbia foUowinp; 

 the winter of 1908-09 than following the winter of 1904-05 when 

 the temperature ffll (o -25 F. on l'\'bruar\' 13. A temperature of 

 -12 F. on February 2, 1905, killed only a very small percentaRc of 

 the buds of such tender varieties as Yellow St. John. It ma\' be 

 said too that a temperature of -15 V. on January 7, 1912, kilUil 

 practically every peach bud at Koshkonong, Missouri. B\ referring
