when this is full the liquid escapes into the smaller
tubes, and as these are open below, it flows out, of course, on to the
food. Let us imagine this to be sugar. The saliva meets the sugar, and
the syrup which is of course formed is then drawn up along the same
channel as that by which the saliva came down. New surfaces for the
saliva to work upon are constantly exposed by means of some fifty or
sixty exceedingly tiny 'teeth,' which, by the aid of the microscope,
will be found at the opening of the mouth, just where the tube-bearing
flaps join it. The two rod-shaped, hairy organs at the base of the
'tongue,' in the illustration, are organs of touch, and not part of the
'tongue' proper.

THE ELEPHANT AND THE CROCODILE.

A Fable.

An Elephant and a Crocodile were once standing beside a river. They were
disputing as to which was the better animal.

'Look at my strength,' said the Elephant. 'I can tear up a tree, roots
and all, with my trunk.'

'Ah! but quantity is not quality, and your skin is not nearly so tough
as mine,' replied the Crocodile, 'for neither spear, arrow, nor sword
can pierce it.'

Just as they were coming to blows, a Lion happened to pass.

'Heyday, sirs!' said His Majesty, going up to them, 'let me know the
cause of your quarrel.'

'Will you kindly tell us which is the better animal?' cried both at
once.

'Certainly,' said the Lion. 'Do you see that soldier's steel helmet on
yonder wall?' pointing at the same time across the river.

'Yes!' replied the beasts.

'Well, then,' continued the Lion, 'go and fetch it, and bring it to me,
and I shall be able then to decide between you.'

Upon hearing this, off they started. The Crocodile, being used to the
water, reached the opposite bank of the river first, and was not long in
standing beside the wall.

Here he waited till the Elephant came up. The latter, seeing at a glance
how matters stood, extended his long trunk, and reached the helmet quite
easily.

They then made their way together back again across the river. The
Elephant, anxious to keep up with the Crocodile in the water, forgot
that he was carrying the helmet on his back, and a sudden lurch caused
the prize to slip off and sink to the bottom. The Crocodile noticed the
accident, so down he dived, and brought it up in his capacious mouth.
They then returned, and the Crocodile laid the helmet at the Lion's
feet. His Majesty took up the helmet, a
