It was early on the fifteenth day that I heard a curious, familiar
sequence of sounds in the kitchen, and, listening, identified it as
the snuffing and scratching of a dog.  Going into the kitchen, I saw a
dog's nose peering in through a break among the ruddy fronds.  This
greatly surprised me.  At the scent of me he barked shortly.

I thought if I could induce him to come into the place quietly I
should be able, perhaps, to kill and eat him; and in any case, it
would be advisable to kill him, lest his actions attracted the
attention of the Martians.
