lows through disease resistance. Wis. Agr. Exp. Sta. Res. 
Bull. 38. 1915. 
(This contains an account of this disease, caused by Fusarium 
conglutinans , with a general statement of the relation of tempera¬

ture to its occurrence. Ann. Mo. Bot. Gard. 3:25-84. 
1916. 
(This gives in detail experimental evidence for the conclusion 
that this disease is limited by low soil temperatures, about 17° C., 
based on field and laboratory investigations of which the first part 
was made at Wisconsin, the last at the Missouri Botanical Garden.)

power of Fusarium lini. Phytopath. 7: 356-360. 1917. 
(Experimental evidence that flax wilt, caused by Fusarium lini ,

ture, Bureau of Plant Industry, the authors undertook an in¬

of tobacco root rot caused by Thielavia basicola. They studied the
