To draw the Hoops of a Churn or Barrel in Perspective.

This problem is nothing more
than another example of the third

b cl, which will give the two sides of the churn, and then
begin with the middle hoop ef, which, being immedi-
ately on the horizontal line, will appear perfectly straight;
next draw the hoop g h, which, being a little above the
horizontal line, will appear like a very narrow ellipsis,
whilst the top hoop, being still higher, will be still broader
as the eye sees more under it. In the same manner
draw the other hoops of the churn, which being lower
than the horizontal line, will grow broader and broader
as they get lower down, the eye seeing more over them.
When the object is extremely large, and the student is
afraid that he cannot draw them sufficiently true with
the hand, he may draw them in perspective by enclosing
each hoop in a square as described in problem third.

problem, and is to be done by
imagining the churn or barrel to
be transparent. In the annexed
example, fig. 7, let A B be the
base line and C D the horizontal

line. First draw the two lines a c, a
