In the centre of the vessel was the machinery, occupying altogether a space of about thirty feet by twenty.

The larger portion of this area was, of course, taken up by the generator, above which was the receptacle of the apergy.

From this descended right through the floor a conducting bar in an antapergic sheath, so divided that without separating it from the upper portion the lower might revolve in any direction through an angle of twenty minutes (20').

This, of course, was intended to direct the stream of the repulsive force against the Sun.

The angle might have been extended to thirty minutes, but that I deemed it inexpedient to rely upon a force, directed against the outer portions of the Sun's disc, believing that these are occupied by matter of density so small that it might afford no sufficient base, so to speak, for the repulsive action.
