ing to note that the per cent of smut was greatest on the latest sow¬ 
ings as the experiments of Brefehl would lead us to expect. The wheat 
was soaked in the fungicides or subjected to their vapors in case of 
chloroform, etc. 
The experiments which proved most successful were as follows: 
No. 13. Hot water 131-132° F., 15 minutes. Smutted grains skimmed off. 
No. 15. Hot water 132-l.sl° F., 15 minutes. Smutted grains not skimmed off. 
No. 21. Copper sulphate, 8 per cent., 24 hours; not limed. 
No. 23. Copper sulphate, 8 per cent., 24 hours ; limed. 
No. 25. Copper sulphate, 5 per cent., 21 hours ; not limed. 
No. 27. Bordeaux mixture, 36 hours. 
No. 29. Bordeaux mixture, half strength, 36 hours. 
No. 45. Arsenic, saturated aqueous solution, 24 hours. 
No. 57. Copper sulphate. £ per cent, solution, 24 hours. 
No. 87. Potassium bichromate, 5 per cent, solution, 20 hours.

The authors recommend the Jensen or hot-water method as the best 
on the whole. This treatment did not destroy quite all the smut, but 
it killed none of the wheat grains, and gave the largest yield except 
No. 87, which was only a small plot. Full directions are given for mak¬ 
ing this treatment. 
The bulletin shows evidence of unusual care in preparation and a 
visit to the station during the progress of the experiment led me to be¬ 
lieve that particular attention was given to all the details of the experi¬ 
ment, which is one involving a very great amount of painstaking labor. 
The graphic illustrations deserve special commendation.—E rwin F.

NEW SPECIES OF UREDINE/E AND USTILAGINE^. 
By J. B. Ellis and B. M. Everhart. 
Schrceteria annulata, n. s. In ovaries of Andropogon annulatus 
from India (Herb, of S. M. Tracy). Mass of spores brownish black, pul¬ 
verulent. Spores in twos or occasionally in threes, flattened on the line 
of contact, hyaline and 12-15// diameter at first, becoming brown and 
separating into two distinct spores 7-10// diameter. Epispore smooth or 
nearly so.
