A hundred stones are placed, in a straight line, a yard distant from each other. How many yards must a person walk, who undertakes to pick them up, and place them in a basket stationed one yard from the first stone?
Click to Flip
In solving this question it is clear that to pick up the first stone and put it into the basket, the person must walk two yards, one in going for the stone and another in returning with it; that for the second stone he must walk four yards, and so on increasing by two as far as the hundredth, when he must walk two hundred yards, so that the sum total will be the product of 202 multiplied by 50, or 10,100 yards. If any one does not see why we multiply 202 by 50 in getting the answer, we refer him to his arithmetic.

Difficult riddles

Two schoolgirls were traveling from the city to a dacha (summer cottage) on an electric train.
"I notice," one of the girls said "that the dacha trains coming in the opposite direction pass us every 5 minutes. What do you think-how many dacha trains arrive in the city in an hour, given equal speeds in both directions?"
"Twelve, of course," the other girl answered, "because 60 divided by 5 equals 12."
The first girl did not agree. What do you think?
Click to Flip
If the girls had been on a standing train, the first girl's calculations would have been correct, but their train was moving. It took 5 minutes to meet a second train, but then it took the second train 5 more minutes to reach where the girls met the first train. So the time between trains is 10 minutes, not 5, and only 6 trains per hour arrive in the city.

�Tis found in our troubles, �tis mixed with our pleasures,
�Tis laid up above with our heavenly treasures;
�Tis whispered in heaven, and �tis muttered in hell,
And it findeth a place in each sybilline spell;
In Paradise nestled, �mid Eden�s fair flowers,
It has sported with Eve in rose-perfumed bowers;
�Tis muttered in curses, yet breathed in our prayers;
From the path of our duty it tempts us in snares.
Deep, deep in our hearts you will find it engraved;
Though in misery sunk, yet from sin it is saved.
�Tis found in the stream that flows on to the ocean;
Though in bustle forever, �tis ne�er in commotion.
�Tis wafted afar o�er the land in each breath;
In the grave �tis decaying�you'll find it in death.
It is floating away on the broad stream of time,
Yet it findeth a place in eternity�s clime.
In the legends of nations it holdeth a place;
There�s no charm without it to the beautiful face.
In thunder you'll hear it, if closely you listen;
In moonbeam and sunbeam forever �twill glisten.
In the dew-drop it sparkles; �tis found in the forest;
It whispers in peace when our need is the sorest.
