There was no mistake about the “wooden tombstone,” but that this was the cause of old Kate’s rheumatism one might take the liberty to doubt.

Kate was a staunch believer in ghosts, goblins, fairies, kelpies, brownies, spunkies, and all the rest of the supernatural family; and I have something to relate in connection with this, though it is not altogether to the credit of my hero, Archie.

Old Kate and young Peter were frequent visitors to the room in the tower, for the tea Archie made, and the fires he kept on, were both most excellent in their way.

“Boys will be boys,” and Archie was a little inclined to practical joking. It made him laugh, so he said, and laughing made one fat.

It happened that, one dark winter’s evening, old Kate was invited up into the tower, and Branson with Peter came also. Archie volunteered a song, and Branson played many a fine old air on his fiddle, so that the first part of the evening passed away pleasantly and even merrily enough. Old Kate drank cup after cup of tea as she sat in that weird old chair, and, by-and-by, Archie, the naughty boy that he was, led the conversation round to ghosts. The ancient dame was in her element now; she launched forth into story after story, and each was more hair-stirring than its predecessor.

Elsie and Archie occupied their favourite place on a bear’s skin in front of the low fire; and while Kate still droned on, and Branson listened with eyes and mouth wide open, the boy might have been noticed to stoop down, and whisper something in his sister’s ear.

Almost immediately after a rattling of chains could be heard in one of the turrets. Both Kate and Branson started, and the former could not be prevailed upon to resume her story till Archie lit a candle and walked all round the room, drawing back the turret curtains to show no one was there.

Once again old Kate began, and once again chains were heard to rattle, and a still more awesome sound followed—a long, low, deep-bass groan, while at the same time, strange to say, the candle in Archie’s hand burnt blue. To add to the fearsomeness of the situation, while the chain continued to rattle, and the groaning now and then, there was a very appreciable odour of sulphur in the apartment. This was the climax. Old Kate screamed, and the big keeper, Branson, fell on his knees in terror. Even Elsie, though she had an inkling of what was to happen, began to feel afraid.

“There now, granny,” cried Archie, having carried the joke far enough, “here is the groaning ghost.” As he spoke he produced a pair of kitchen bellows, with a musical reed in the pipe, which he proceeded to sound in old Kate’s very face, looking a very mischievous imp while he did so.

“Oh,” said old Kate, “what a scare the laddie has given me. But the chain?”
