The figure shows vessels occupied, the formation of small bacterial cavities, and a well-developed incipient root (R), the growth of which has been stimulated by the pres- ence of the bacteria at a distance. Several much more rudimentary roots are depicted in the upper portion of the fig- ure (Rr). At the left, above the lower cavity, the bacteria fill the intercellular spaces around a few cells (X). The bast fibers are not distinct in the section itself, which was stained with special reference to the bacteria. There are no bac- teria immediately under or in the budding root (R). Slide 111 (2.
