In 1922 black ch:,ff was reported from Oklahoma, northwestern Arkansas, isconsin, lov/a, I^orth Dakota (Cass and Pierce Counties infested, although others ght have been and not reported ^ V/eniger), eastern oouth Dakota (no data on dis- tribution west of (Missouri) River - Ivans), and southern Kansas. The disfeaseuwas".v;idespread in Oklahoma, extending south'.vestward from the north-central part, where it was worst, according to Stratton, and causing severe osses in some fields- Gtratton believes that the v.^et spring may have been re- sponsible for the large amount of black chaff in the state. Of interest in this connection is MelcHers' statement (July I5) that black chaff was found in southern Kansas v/here most of the rainfall of the state occurred. Dates when the disease v/as first recorded are; June 3» ^-alters, Oklahoma; June, Fayetteville, Arkansas, and Brookings, South Dakota; July iG, Rugby, North Dakota.
