The inner surface of the bowl is flanged to take 3 sets of special cards for use at different periods of the year. A semi-circular brass bar supports the bowl and sphere and has degrees of latitudes engraved on it. It can be moved and set to any latitude in its range. The rays of the sun when focused sharply on the card bum a trace on the card gradually. The length of the burn indicates the duration of sunshine. which is read off the hour marks printed on the cards.
