Then the Voice answered her-- "Yes--if you come alone!" These words sounded so close to her ear that she felt sure the speaker must be standing beside her.
"I will come!" she said, impulsively--"Somehow--some way!--no matter how difficult or dangerous! I will come!" As she spoke she was conscious of a curious vibration round her, as though some other thing than the ceaseless, silent throbbing of the air-ship's mechanism had disturbed the atmosphere.
"Wait!" said the Voice--"You say this without thought.

You do not realise the meaning of your words.

For--if you come, you must stay!" A thrill ran through her blood.
"I must stay!" she echoed--"Why ?" "Because you have learned the Life-Secret,"-- answered the Voice--"And, as you have learned it, so must you live.

I will tell you more if you care to hear--" An inrush of energy came to her as she listened--she felt that the unseen speaker acknowledged the power which she herself knew she possessed.
"With all my soul I care to hear!" she said--"But where do you speak from?
And who are you that speak ?" "I speak from the central Watch-Tower,"-- the Voice replied--"The City is guarded from that point--and from there we can send messages all over the world in every known language.

Sometimes they are understood--more often they are ignored,--but we, who have lived since before the coming of Christ, have no concern with such as do not or will not hear.
