In the illustration
we have a sketch of Sir Edwyn
de Tudor going to rescue his lady-love, the fair Isabella, who was held
a captive by a neighbouring wicked baron. Sir Edwyn calculated that if
he rode fifteen miles an hour he would arrive at the castle an hour too
soon, while if he rode ten miles an hour he would get there just an
hour too late.
Now, it was of the
first importance that he should
arrive at the exact time appointed, in order that the rescue that he
had planned should be a success, and the time of the tryst was five
o'clock, when the captive lady would be taking her afternoon
puzzle is to discover exactly how far Sir Edwyn de Tudor had to ride.
