Nay, it is not strained; I can judge of the breaking strength of a bow.

Whether or no I can judge of the flight of an arrow you will learn hereafter.

But that this one flew fast and far cannot be doubted since--did you watchers note it ?--its speed made it shine like fire.

This is caused by the rubbing of the air when aught travels through it very quickly.

This night you have seen a meteor glow in the same fashion, only because the air fretted it in its passage.
In the East, whence I come, we produce fire just so.
