walls grew vast masses of those delicate light-giving fungous rootlets, the glow of which was so strong that I had no difficulty in reading the writing on my tablets; in fact, I stood there for several minutes making entries by the light of these bunches of glowing rootlets.
Then the thought flashed through my mind,—
“Which way shall I turn, to the right or to the left?”
Bulger comprehended the cause of my vacillation and made haste to come to my rescue. After sniffing the air, first in one direction and then in the other, he chose the right hand, and I followed without a thought of questioning his wisdom.
