This is a serious business, Doctor.
gpt
It is, indeed!
human
We have not even an instrument, some glass that we might take the lens out of, and use like a burning glass.
gpt
No, and it is a great pity, for the sun's rays are quite strong enough just now to light our tinder.
human
Well, said Hatteras,
gpt
Yes! replied Clawbonny, speaking to himself, absorbed in his own reflections.
human
Yes, that might do at a pinch! Why not? We might try.
gpt
What are you dreaming about?
human
An idea has just occurred to me.
gpt
An idea come into your head, Doctor, exclaimed Johnson;
human
Will it succeed? that's the question.
gpt
What's your project?
human
We want a lens; well, let us make one.
gpt
How?
human
With a piece of ice.
gpt
What? Do you think that would do?
human
Why not? All that is needed is to collect the sun's rays into one common focus, and ice will serve that purpose as well as the finest crystal.
gpt
Is it possible?
human
Yes, only I should like fresh water ice, it is harder and more transparent than the other.
gpt
There it is to your hand, if I am not much mistaken,
human
I fancy that is fresh water, from the dark look of it, and the green tinge.
gpt
You are right. Bring your hatchet, Johnson.
