CHARACTEES OP GALL ORGANISMS FROM OTHER SOURCES. 153 



(3) Copious reduction: Newest daisy, old daisy, new rose, hop, 

 arbutus, alfalfa, Flats poplar, turnip. 



All the organisms about which we felt any etiological certainty fell 

 into class 2 or class 3. 



Table X. — Showing behavior a of crown-gall organisms in river icater containing other 



stated ingredients, at room temperature. 



a Explanation of figures indicating growth: = No growth; 2=slight; 3 = fairly good; 4 = good; 5=heavy. 



b Possibly no use of glycocoll by any of the strains. 



c No increase in an additional 69 days. 



d Turbid; cloudy on shaking. 



e Forty-four days. 



/ Forty- four days, another tube more copiously inoculated. 



g No growth later. 



A Plug wet.

Tubes were now tested for indol. Those marked with a star (*) gave distinct indol reaction without 

 heating; those with a dagger (t). on heating. The otliers were negative. (See Table IX, p. 147.) The 

 indol reactions were not as deep red as in case of Bacillus coli.
