Some old riddles

Riddle 1:
Little trotty hetty coat
in a long petticoat
and a red nose
the longer she stands
the shorter she grows.

RIDDLE 2:
The land was white
the seed was black
it'll take a good scholar
to riddle me that.

RIDDLE 3
Riddle me! riddle me! What is that:
Over your head and under your hat?

RIDDLE 4

George walked for thirty minutes in the pouring rain without getting a single hair on his head wet. He didn't have a hat or an umbrella and his coat had no hood. How did he do that?

I'm going to count this as my Sunday puzzle/riddle, so we'll be back on schedule on Monday when I post the answer to these four.
