Which makes a winding pattern here?

FEODOR. That is
The Volga.

TSAR. Very good! Here's the sweet fruit
Of learning. One can view as from the clouds
Our whole dominion at a glance; its frontiers,
Its towns, its rivers. Learn, my son; 'tis science
Which gives to us an abstract of the events
Of our swift-flowing life. Some day, perchance
Soon, all the lands which thou so cunningly
Today hast drawn on paper, all will come
Under thy hand. Learn, therefore; and more smoothly,
More clearly wilt thou take, my son, upon thee
The cares of state.

(SEMYON Godunov enters.)

But there comes Godunov
Bringing reports to me. (To KSENIA.) Go to thy chamber
Dearest; farewe1l, my child; God comfort thee.

(Exeunt KSENIA and NURSE.)

What news hast thou for me, Semyon Nikitich?

SEMYON G. Today at dawn the butler of Prince Shuisky
And Pushkin's servant brought me information.
