fungicide is not given but it consists mainly of potassium sulfid. 
Other important ingredients are, according to Jensen, also 
added. He manufactures the ingredients and they are doubtless 
of purity superior to those usually kept in drug stores, and 
probably not too expensive, considering the quality. 
The method of application is wholly different from that 
employed by myself and Mr. Swingle. 1 can, after trial, highly 
recommend it. A solution is made by dissolving 2 ibs. in 125 
liters of water. This is intended for 1000 tbs. of seed. It is 
poured on the seed grain by means of an ordinary watering can, 
the mass at the same time being shoveled over and over ona tight 
floor, so that the solution may come in contact with every grain. 
The stirring of the heap of grain is repeated twice daily, the 
sowing to be done four or five days after the treatment. The 
heating will not be detrimental if the mass of grain is not more 
than six or eight inches deep. The initial stages of germination, 
which will be entered upon, are claimed to be of decided 
advantage. 
My own experiments with this fungicide, though not yet 
completed, show that it is remarkably efficient and that it justifies 
the claims made for it by the originator.
