Sorghum Smut in Adams County. — A small field of Sorghum 
near Mineral Springs Station, Adams County, Ohio, was observed 
last November to be badly infected with the grain smut of Sorghum, 
known to botanists as ustilago sorghi, or perhaps more correctly 
designated (according to G. P. Clinton) as Cintractia sorghi-vulgaris. 
A careful inspection of the harvested stalks, still piled in the field, 
showed that fully twenty per cent, of the panicles or heads were 
infected. When there is infection by this smut, usually every grain 
in the panicle is smutted according to repeated observations in 
various localities. The field in question was very thickly planted to 
sorghum, the crop evidently being intended for stock feed. The 
only other locality reported in Ohio for this smut, so far as at present 
recalled, is Columbus, where however it has occurred only upon 
artificial infection. Broom corn also was here successfully infected. 
Sorghum is often cultivated, but not in large quantities in Ohio; a 
large acreage of broom corn is however annually planted. Request 
is hereby made for reports in case this smut is noticed in other 
localities in our State. The Head-smut of Sorghum, Ustilago 
reiliana, should also be reported if observed. 
Notes on some Rusts.— M. A. Carleton, of the United States 
Department of Agriculture, has published some observations and 
experiments on a few rusts that are of special interest, and may well
