 sor^liuni in Kansas, Untilagosorghi, wliicli attacks the individual j-rains, 

 and Uatilago reiliana, which converts the whole head into a larj>"e black 

 mass, UaiUago sorf/M (Passerini in Tliiini. TTerb. myc. oec. n., (>,'}) has 

 been reported in this countrj' from Washington, I). C; Madison, Wis- 

 consin; Xew York; Lincoln, Nebraska; and Manhattan and Sterling', 

 Ivaiisas, on ]dants orown from foreign seed. 



i'stihu/o reiliana (Kiilni in Eabenhorst, Fungi europ.nei exsiccati, 

 <'ent., 20, No. 1988) was found in 1800 at Manhattan and Sterling, 

 Ivansas and in New Jersey, on plants from foreign seed. In a pre- 

 liminary test in a greenhouse at the station with the seed of Red Lib- 

 ciian, Kangoon, Early Amber, White Kaffir Corn, and a variety from 

 ('alcutta the j^lants in nine of the fifteen pots in which infected seed 

 was planted, produced smutted heads ( Usiilago soryM in seven cases and 

 V. niliana in two cases). \ lield experiment with infected seed, and 

 with potassium sulphide, chloride of iron, and hot water as fungicides 

 to prevent the smut, is also reported in notes and tables. The untreated 

 ]>lats gave from 1 to 3.3 per cent of snnitted heads and there was no 

 snuit where either potassium sulphide or hot water was used. " The 

 artificial infection of the seed does not seem to be successful." 



Experiments with corn smut, W. A. Kellerman, Ph. D. (pp. 

 101-10,")). — Attempts in the greenhouse and in the lield to infect corn 

 l)y adding a quantity of the spores of corn smut {JJstUaf/o ze(e-mays) to 

 the seed were unsuccessful. Spraying corn ]ilantswitli Bordeaux mix- 

 ture, chloride of iron, or potassium sulphide did not prevent the devel- 

 opment of corn smut. Details are given in notes and tables.

Feeding experiments with milch cows, C. A. Goessmann, Ph. 

 D. (i>i>. 4-lG). — These experiments were designed to compare the etiects 

 of like amounts of cotton-seed meal, old-process linseed meal, and 

 gluten meal on the cost of food and the (piantity and (juality of milk

 3 itounds of wheat bran, and coarse foods consisting of rowen hay, corn 

 stover or hay, and a mixed silage made of efjual parts by weight 

 of green fodder corn and green soja beans. The rations fed each
