THE SCHOOL-TEACHER “CAUGHT.”

Two of our Public Schools were engaged playing a football match one

afternoon. The head master of one of them had generously given the

boys a half-holiday; but the gentleman who held the same capacity in

the other school, not being an ardent admirer of Australia’s national

game, refused to do so. When school assembled in the afternoon, a

boy volunteered to ask the master for the desired holiday. When the

question was put, he firmly answered, “No, no!” whereupon the bright

youth called out: “Hurrah! we have our holiday; two negatives make an

affirmative.” The teacher was so pleased at the boy’s sharpness that

he dismissed the school right away.

195. A man arrives at the railway station nearest to his home 1½

hours before the time at which he had ordered his carriage to meet

him. He sets out at once to walk at the rate of four miles an hour,

and, meeting his carriage when it had travelled eight miles, reaches

home exactly one hour earlier than he had originally expected. How

far was his house from the station, and at what rate was his carriage

driven?

“OFF THE TRACK.”

196. A man starts to walk from a town, A, to a town B, a distance by

road of 16 miles, at the rate of 4 miles an hour. There is a point

C on the road, at which the road to B leads away to the right, and

another road at right-angles to this latter goes to the left, “to no

place in particular.” The unwary traveller gets on to this left hand

road, and is walking for 2¼ hours since he left A, before he finds

out his mistake, and he resolves not to go back to the junction,

which is five miles away, but makes straight across the bush to B,

and strikes it exactly. How long did it take to go from A to B?
