an extinct form of elephant, stands in one of the great halls, and a few
live creatures still inhabit the gloomy depths. A cave-rat as large as a
rabbit was caught, which, although it had very bright eyes, was quite
blind when taken from the cave; but after a month's experience of
daylight it gradually began to make use of its eyes. Various kinds of
eyeless fish and crabs live in the dark waters, and a live frog was seen
wearing an unhappy expression of countenance.
The slow rate at which stalagmites grow has been tested in this cavern
by a lantern which was dropped in 1812 and found cemented to the floor
in 1843, since which its upward progress has been carefully watched. The
Mammoth Cave contains immense quantities of nitre. During the great
American Civil War, most of that used was found here, and as gunpowder
contains two-thirds of nitre to all its other ingredients, these caverns
were of great value to the nation. The Mammoth Cave is now private
property, belonging to Dr. John Crogan, who gave ten thousand dollars
for it.

Beyond the meadow lay a field of wheat, tall and yellow, although not
yet quite ripe for the sickle. Stooping until my hands almost touched
the ground, I ran as fast as possible under the shelter of the friendly
hedge, until, reaching the cornfield, I scrambled through another hedge,
and lay down on my face amidst the wheat.
But still it was impossible to feel in the slightest degree safe, the
road being only a few yards distant, while I distinctly heard the sound
of approaching wheels. If it had not been for the bend in the lane, I
should scarcely have been able to delay capture many minutes, and even
as it was, I lay quaking while I wondered whether Mr. Turton would be
able to see me from the road.
The cab passed my hiding-place, however, so that I began to hope it
might not be going to stop, until on the point of rising, I heard the
horse pulled up, heard the door opened, and recognised Mr. Turton's
voice as he told Augustus to alight.
'The boy must be hiding somewhere hereabouts,' he exclaimed.
'He might easily have got into that wood,' said Augustus, and I
regretted that in my haste I had not taken to the wood on the other side
of the road.
While Augustus and his father must have gone to inspe
