The sergeant withdrew, and Downy touched Chris on the shoulder.

‘It’s a bad business, miss,’ he said.  ’You made a plucky fight, but this was inevitable.  Will you tell me where he was hidden?’

Chris arose and stood with her back to the wall and answered him in a firm voice.  She understood the futility of further evasion.

‘He hid in the tank,’ she said.  ’It has a false bottom, and you get in from below.’

The detective expressed incredulity in a long breath.

‘Well, that fairly beats me,’ he said.  ‘When did he fix the tank?’

’I do not know.  I had no idea it was done until the night of the arrest of Rogers.’

At this moment Casey and Keel entered.

‘Stand by the man, Casey,’ said the detective.  ‘Keel, follow me.’

Downy went straight to the tank and, creeping under it, struck a match and examined the floor above on which it rested.  Two of the boards had been moved aside, and in the bottom of the tank there was an opening about eighteen inches in diameter with a sheet of iron to cover it, in such a way as to deceive any but the most careful seeker.  The detective ordered Keel to bring a candle, and when it was forth coming he drew himself up into the tank and struck a light.  An ejaculation of delight broke from his lips, for there at his hand lay a skin bag covered with red-and-white hair, and by its side shone a magnificent nugget shaped like a man’s boot.  This the detective recognised as the nugget described by Dick Haddon.  There were also a pickle bottle containing much rough gold, and two or three small parcels.

The compartment in which Downy sat was just high enough to allow of a man sitting upright in it, and large enough to enable him to lie in a crescent position with out discomfort.  A pipe from the roof was connected with the tap, so that water could be drawn from the tank as usual.  The job had been carefully done, and had evidently cost Shine much labour.  The searcher had designed the compartment as a hiding-place for his treasure, the quantity of which convinced Downy that his depredations at the mine (in conjunction with Rogers, probably) had been of long standing.  The parcels contained sovereigns and there were small bags of silver and copper—­a miser’s hoard.  The detective dropped the bag, the nugget, and all the other articles of value out of the tank, and with the assistance of Keel carried them into the kitchen.  He examined the material in the hide bag, and found it to be washdirt showing coarse gold freely.  The nugget was a magnificent one, containing, as the detective guessed, about five hundred ounces of gold, and worth probably close upon two thousand pounds.  Nothing nearly so fine had ever before been discovered in the Silver Stream gutters, although they had always been rich in nuggets.

When Mrs. Hardy returned home an hour later, Harry had just come in from work.  The shareholders in the Native Youth were so anxious to cut the stone that they were putting in long shifts.  There were traces of tears about Mrs. Hardy’s eyes, and her expression of deep sorrow alarmed her son.
