“Buried treasure!” he echoed, and he burst out laughing. “Sounds well, at any rate. I’m always open to receive a bit of treasure from any source.”

“Well, we want you to help us to dig. It is believed to be over at Threave.”

“What! the old ruin we went to the other day?” Sammy exclaimed. “Better buy a new pair of oars, old chap, if you don’t want the whole crowd of us shipwrecked.”

The suggestion was a good one; and, although the weather was so much against it, Sammy presently went forth, purchased a pair of heavy second-hand oars, and stowed them away in the bottom of a light wagonette which we had hired at the hotel to take us to Kelton later in the day.

Sammy was just as excited as we were, and entered as keenly into the spirit of the thing. Like Fred, he never did anything by halves. He was a man with muscles like iron, and possessed the courage of a lion, as proved by the many tight corners he had been in during the Indian frontier wars of the past fifteen years or so. As a shot, Sammy Waldron was only equalled by his host, Fred Fenwicke; but, while the latter’s form showed best among the grouse, Sammy was pre-eminently a hunter of big game, who sent presents of bears and tigers to his friends, instead of pheasants and grouse.

The morning wore on. A long council of war was held, but the rain did not abate.

Not indeed until we sat down to luncheon at twelve did the weather clear, and with it our spirits rose again. At half-past one the clouds broke and the sun came forth fitfully. Then all four of us, eager to investigate, and not knowing what difficulties were before us, mounted into the wagonette and drove out along the winding road to Kelton Mains.

On descending, a surprise awaited us, for when we asked for the tools sent there from Grierson’s the farmer told us that three gentlemen, one a deformed man, had arrived there the day before, claimed the picks and spades, and had crossed to the island and been occupied in digging until it was dark.

The trio of investigators might still be on the island for aught we knew.

This was certainly disconcerting, and we walked through the fields to the water’s edge full of expectancy. We, however, found the old boat moored in its usual place, which showed that the party had returned to shore. Therefore we embarked, eager to take observations and follow the directions laid down, even if we were not that day able to make investigation.
