Thank you. > I am puzzled by only one thing: Why was the sun rising above a house SOUTH > of yours? Shouldn't that be EAST? > Sorry for not being clear enough. My lot is not in a perfect East-West Direction. In this seasonthe sun rises further to the South which means in the first hours of the day its light is blocked by a house that is next to mine, in the South direction (in fact, more Southeast). See the most crude diagram bellow. N +--------------------+ W | | | sd MH| +--------------------+ | NH | | | +--------------------+ s S sd is the place where I am drawing the compass rose with cardinal lines; MH is my house and NH is my neighbor's house. s is the sun. Things are so disposed that after a certain date (some time in September), if I am in my backyard (particularly at sd) I'll see the sun rising from behind his house. > Your English is excellent.

I noticed I had madethat mistake when I arrived home and started doing some calculation for the other sides of the square column. When I opened Albert E. Waugh's "Sundials - Their Theory and Construction" on chapter 10 (Vertical Declining Dials) I detected my mistake... Too late.
