The further I turn it this way to the right, the more the R.Force overcomes the attractive force of the earth or any other planet that we may visit.

Turn it back, and gravitation asserts itself.

If I put this arrow-head on the wheel opposite zero the weight of the _Astronef_ is about a hundred and fifty tons, and of course she would go down like a stone, and a very big one at that.

At ten she weighs nothing; that is to say the R.Force exactly counteracts gravitation.

At eleven she begins to rise.
