in office 2007 I cannot see how to draw a horizontal line in a letter.

I think you want, in Word 2007:

Home | Paragraph Group | Second Row at far right: This is the Borders
and Shading Icon.

(What shows, and the screen tip, is the last selection you've made.)

If you click the drop-down arrow at the right of the icon, you'll see a
menu. "Horizontal Line" is towards the bottom.

You could use a bottom border instead of the graphic "horizontal line",
if that better suits your needs.
