Threats, and the application of a string twisted round the thumb, and tightened until the blood spurted from beneath the nails--rough modes of questioning which had not yet died out--soon elicited from the captives the place where the arch-conspirator had been staying while he laid the train for the explosion; but, as was expected, a search showed that the bird had flown, without leaving a trace behind him.

Then, as there was nothing more to do until morning, and two score of horsemen had been sent off in different directions, and the officers most acquainted with the haunts of the bad characters were set quietly at work to search for some clue that might help to find the hiding place of Maria, the magistrates took their leave with many expressions of regret and commiseration with the merchant, and with confession of a consciousness of deep fault that they had not taken to heart his warnings.

Long ere this the bodies of the score of rioters who had fallen on the stairs, hall, and passages had been removed; and leaving the afflicted merchant for awhile to his thoughts, Rupert retired to his room, telling Hugh and Joe to follow him. He explained to them exactly the steps which had been taken, and his opinion as to the true state of things; and bade them think the matter over in every light, and to come to him at daybreak, and let him know if any plan for the conduct of the search had occurred to them.

The result of the night's thoughts and of the morning's deliberations was conveyed to Mynheer van Duyk by Rupert.

"The first thing to be done is to offer a large reward, sir, for any news which may lead to the discovery of your daughter. This may or may not bring us in some information. The next thing is to have an eye kept on every boat by the quay which may have a cabin or half-deck capable of concealing a person wrapped up and bound. Also, that a watch should be set upon any fishing boat anchored in the river, or moored against the banks, for miles round. It is very possible that she was carried on board, and that there she may be kept, close to us, for days, or even weeks, until the hotness of the search is over, and they can pass up or down the river without being stopped and overhauled."

"We will have every boat at the quay searched at once; and boat parties shall be sent off to examine every craft at anchor or moored in the river."

"I think, sir, that it behoves us to act with care," Rupert said; "for knowing the desperate nature of this villain, I think it probable that he would wreak his hate upon your daughter, and do some terrible crime when he found that he was discovered, for he knows that his life is already forfeit. When we find out where she is confined, to my mind the serious difficulty only commences, for it is absolutely necessary that the arrest be so prompt and sudden, that he shall not have time even to level a pistol at her."

Van Duyk acknowledged the justice of Rupert's reasoning.

"Hugh has suggested that it is likely that he has in his pay the same boatmen whom he employed last year to murder us. As a first step, let one of your clerks go down with an officer to the quay, and inquire what boats left here yesterday or in the night. Hugh will put on a rough fisherman's suit, and with his hat well down over his brows, will stroll along by the water, to see if he recognizes the face of any of the men."

At eight o'clock in the morning there was a meeting of the council of the town, to determine upon the measures to be taken to discover the authors of this disgraceful outbreak, and to take steps for the recovery of the daughter of the leading citizen of the town. Criers had already gone round to offer rewards for information; and a proclamation was now issued by the magistrates, calling upon every citizen to do his best to aid in the search. A committee was appointed, to investigate all information which might be brought in.
