proached directly that matter which my growing
liking for him was turning into strong desire.

"Drake," I asked. "Where are you going?"

"With you," he laughed. "I'm foot loose and fancy free. And I think you
ought to have somebody with you to help watch that cook. He might get
away."

The idea seemed to appall him.

"Fine!" I exclaimed heartily, and thrust out my hand to him. "I'm
thinking of striking over the range soon to the Manasarowar Lakes.
There's a curious flora I'd like to study."

"Anywhere you say suits me," he answered.

We clasped hands on our partnership and soon we were on our way to the
valley's western gate; our united caravans stringing along behind us.
Mile after mile we trudged through the blue poppies, discussing the
enigmas of the twilight and of the night.

In the light of day their breath of vague terror was dissipated.
There was no place for mystery nor dread under this floor of brilliant
sunshine. The smiling sapphire floor rolled ever on before us.

Whispering little playful breezes flew down the slopes to gossip for a

"I know," he said. "Of course I understand all that--superimposed layers
of warmer air that might have bent the ray; vortices in the higher
levels that might have produced just that effect of the captured aurora.
I admit it's all possible. I'll even admit it's all probable, but damn
me, Doc, if I BELIEVE it! I had too clearly the feeling of a CONSCIOUS
force, a something that KNEW exactly what it was doing--and had a REASON
for it."

It was mid-afternoon.

The spell of the valley upon us, we had gone leisurely. The western
mount was close, the mouth of the gorge through which we must pass,
now plain before us. It did not seem as though we could reach it before
dusk, and Drake and I were reconciled to spending another night in the
peaceful vale. Plodding along, deep in thought, I was startled by his
