62.--THE CLUB CLOCK.

One of the big clocks in the Cogitators' Club was found the other night

to have stopped just when, as will be seen in the illustration, the

second hand was exactly midway between the other two hands. One of the

members proposed to some of his friends that they should tell him the

exact time when (if the clock had not stopped) the second hand would

next again have been midway between the minute hand and the hour hand.

Can you find the correct time that it would happen?
