Last spring (1913) the Sycamore blight (Gnomonia veneta (Sacc. & Speg.) Kleb.) was very prevalent and destructive in the vicinity of Ames. All the large trees along Squaw Creek looked as though the young foliage and growth had been killed by frost except a few tufts in the extreme tops of the trees. Young trees several years planted suffered somewhat, but none to the extent that the large trees did. About one-half of these young trees showed some traces of the disease. During August the effects of its ravages were noted in eastern Nebraska and at Lamoni, Decatur County, Iowa. Doctor Pammel also reported it as destructive in Madison County, and in Decatur County at Leon.
