This is, however, my own experience.  I am told others have observed the phenomenon before.

When we were boys at school we used, among other things, to discuss ghosts.  Most of my fellow students asserted that they did not believe in ghosts, but I was one of those who not only believed in their existence but also in their power to do harm to human beings if they liked.  Of course, I was in the minority.  As a matter of fact I knew that all those who said that they did not believe in ghosts told a lie.  They believed in ghosts as much as I did, only they had not the courage to admit their weakness and differ boldly from the sceptics.  Among the lot of unbelievers was one Ram Lal, a student of the Fifth Standard, who swore that he did not believe in ghosts and further that he would do anything to convince us that they did not exist.

It was, therefore, at my suggestion that he decided to go one moon-light night and hammer down a wooden peg into the soft sandy soil of the Hindoo Burning Ghat, it being well known that the ghosts generally put in a visible appearance at a burning ghat on a moon-light night. (A burning ghat is the place where dead bodies of Hindoos are cremated).

It was the warm month of April and the river had shrunk into the size of a nullah or drain.  The real pukka ghat (the bathing place, built of bricks and lime) was about 200 yards from the water of the main stream, with a stretch of sand between.

The ghats are only used in the morning when people come to bathe, and in the evening they are all deserted.  After a game of football on the school grounds we sometimes used to come and sit on the pukka ghat for an hour and return home after nightfall.

Now, it was the 23rd of April and a bright moon-light night, every one of us (there were about a dozen) had told the people at home that there was a function at the school and he might be late.  On this night, it was arranged that the ghost test should take place.

The boy who had challenged the ghost, Ram Lal, was to join us at the pukka ghat at 8 P.M.; and then while we waited there he would walk across the sand and drive the peg into the ground at the place where a dead body had been cremated that very morning.  We were to supply the peg and the hammer. (I had to pay the school gardener two annas for the loan of a peg and a hammer).

Well, we procured the peg and the hammer and proceeded to the pukka ghat.  If the gardener had known what we required the peg and the hammer for, I am sure he would not have lent these to us.

Though I was a firm believer in ghosts yet I did not expect that Ram Lal would be caught.  What I hoped for was that he would not turn up at the trysting place.  But to my disappointment Ram Lal did turn up and at the appointed hour too.  He came boasting as usual, took the peg and the hammer and started across the sand saying that he would break the head of any ghost who might venture within the reach of the hammerhead.  Well, he went along and we waited for his return at the pukka ghat.  It was a glorious night, the whole expanse of sand was shining in the bright moon-light.
