attack are those resulting from drought with succeeding low 
temperature. 
The fact that the germ breaks down cellulose slowly explains 
the manner of its progress from one cell to another, 
Experiments have shown that the germ in a medium of low 
per cent. acid grows nearly or quite as well as in one of alkaline 
nature, so that the acid element of the beet root does not offer 
material resistance to the germ. 
The germ converts cane sugar to glucose in the process of 
producing gas. The amount of gas produced is not constant, 
but the reasons for this irregularity have not been determined. 
The germ grows well with any form of sugar and especially 
well in media containing cane sugar. This fact makes it seem 
probable that the germ is especially at home on those media 
which contain sugar in some form, although it will keep alive om 
media without sugar, and after cultivation for a time on such 
media will adapt itself to the conditions presented. 
ANOTHER ORGANISM SEPARATED FROM THE SUGAR BEET. 
The colorless gelatinous form separated from the beet root 
in connection with the disease germ was at first thought to be 
an undescribed germ or rather the product of a germ, for only @ 
few bacterial bodies could be detected under the microscop® 
even when comparatively large masses of the substance Wer 3 
placed in the field. The organism appeared as small bacilli of : 
micrococci, ek 
The mass resembles the form of Leuconostoc so common! 
the vicinity of sugar refineries. Under the microscope, however, 
no streptococci were found, which characterizes Lene 
under the microscope. The gelatinous substance is pegs 
water and alcohol; in the latter it turns to a milk-white ee 
stance before it dissolves. The substance increased Tap a 
bulk when grown on sterilized beet. The mass did not dry ° 
for months after the substratum had become dry and hard. 
The substance grew well on 10 per cent. cane sugar pa 
The growth was slow at first, but after a week or tw? 1g
