Together we eagerly approached it, first, however, returning to the spot where we had fixed the whereabouts of the main altar, and counting the paces towards it. I counted them as one hundred and twenty-nine, while Walter made them one hundred and thirty-two.

The pond was big, full of dark water, and weedless, showing it to be of considerable depth. It had escaped our notice on entering the abbey grounds, and we both saw that although it was now bounded on one side by the high, black-tarred fence of a cottage garden, and at the end by some red-brick farm outbuildings and hayricks, it had nevertheless once been of considerable dimensions—unquestionably the fish pond of the monks from which they caught their Friday fare.

Once it had undoubtedly been well kept and cared for, but today the cattle grazing on that weedy ground drank from it, for round the mud showed prints of hoofs.

“This is it, no doubt,” exclaimed Wyman, again referring to the record. “You see it says ‘the pond was deep and dried not in summer, being fed by several springs.’ This one is of fresh water, while the other is stagnant. If the treasure has not already been found, it is most likely sunk deep in the mud here.”

We both gazed upon the unruffled surface of the water glittering beneath the sun, wondering in which part had been the centre of the original pond. At present it was not more than twenty feet across and perhaps fifty feet long. Its previous dimensions had, of course, been much greater, for it must have extended nearly the whole length of the abbey if, as seemed so probable, the depression on the east side of the field had been in connection with it.

Of course, we had at once seen that the abbey and monastic buildings had originally spread over all the fields southward, eastward, and northward; but we had here sufficient evidence of the existence of the ponds, the hiding-place of the treasure.

A flock of rooks were lazily circling around the tower, and as we stood there in silence at the edge of the pond the deep-toned abbey bell rang out the hour.

“I cannot see how we can search here without its being known,” Wyman remarked at last. “How are we to pump out this pond and dig out the mud secretly? Why, the whole village would be here in half an hour if we attempted it.”

“I am quite of your opinion,” I answered. “And I would point out further that until we are aware of where the centre of the pond was it is no use searching at all. My idea is that the spot where the treasure lies is not beneath the water at all, but in another place, midway between here and the other pond—a place that has since been filled up with the débris when the abbey was destroyed. As you see, the ground has practically been levelled, yet at one time nearly the whole of this field was a deep pond. Recollect that there were sometimes as many as seven hundred monks here; therefore they required good-sized fish ponds. No; I feel confident that if we ever do discover the treasure we shall find it somewhere about the centre of this field.”

“Which means that we’ve a lot of excavation to do, and that we must disclose our secret to the whole countryside—even if we were successful in obtaining permission from the lord of the manor, the Ecclesiastical Commissioners, or whoever owns the land.”
