'Horticultural?'

'—'Tyculchural place lighted; an' the guard said he feared they wouldn't find it, an' went on, tellin' them they'd better hurry out; an' then he went back the way they'd come, crost the bridge an' all, an' every little way they'd light a match, an' course I got so close I heard her say, "It must 'a' been when I fell down." I thought somebody got a fall when they run from the bridge down into the bushes.'

'Well, did you find where they went?'

'Drat the luck! No! I'd follered them out Midway, and was jest a little ways behind, when a couple o' guards stopped me, and afore I'd got out of their grip the two of 'em was out of sight.'

I was not surprised to hear this. I was quite convinced that the gang had in some manner secured a safe and secret lurking-place in the Plaisance. Still, somehow, I had hoped for something more from Billy's report, and felt somewhat disappointed. But I had yet to learn its true value.

During my absence there had come a message from the bureau asking our presence there. It was the Lausch robbery that 'required our presence,' so the message read, and Dave had returned an answer promising our presence at the earliest moment of leisure.

We did not feel so deeply interested in the Lausch robbery then as in some other matters, but when we had dismissed our boy shadower we went at once to the bureau.

There was considerable excitement at the office, and with good reason. Some of Monsieur Lausch's jewels had been returned, and in a most novel manner.

Early in the morning a guard had appeared with the treasure in his hand, and a singular story upon his lips.

Last night, he had said, while crossing the north-east end of the Wooded Island, at quite a late hour, he had encountered a man and woman searching for a lost purse. They were quite certain it had been lost on the island, and he being then on duty and 'unable to delay,' told them that he would search for it next day, and passed on. Early in the morning he had entered upon the search at the place where he had met the two, and, finding no trace of the lost purse, had turned his search into a stroll about the island. He was quite familiar with the place, having done guard duty there, and going close to the water's edge, at a point where a favourite view was to be had, he observed that one of the skiffs that were moored here and there about the island was gone. Going closer, he saw that it had been roughly torn from its moorings, and the soft soil showed that several people had left traces of their presence. It was in stooping closer, to look at these footprints, that he had noticed a bit of string trailing across the grass just beyond; and taking hold of this, he found a weight upon it, which proved to be a little chamois-skin bag containing some uncut gems. He had at once reported this find to his superior officer, being an honest guard, and was ordered to come with it to the bureau.
