Next, we caused an accurate description of Greenback Bob to be sent to all the gates and different districts, with orders for an instant report of the fact should he be seen, and that once seen he must be constantly shadowed.

Before we left the place we had arranged with Lausch to put a man of our own choosing into the pavilion, whose business it would be to keep constant watch over his people. For while he was ready to vouch for their honesty, we were not; rather, we were not willing to let any possibility of a clue escape us. A second man was placed where he could cultivate these people, and as much as possible outside of business hours. Not that we expected much from this, for we had seen no slightest sign of dishonesty among these people, who seemed to shun all society and to have no acquaintances outside their own pavilion.

After considering long, we decided not to bring the name of Delbras into the case, or to attempt to set any watch upon him in the regular way. To 'locate' Delbras should be our own especial work, and to freshen our memories we reviewed the information furnished our chief by the French commissaire.

So far as was known there was no picture of him extant, and the French report described him about as follows:

'Nationality, French; age, probably about thirty to thirty-three years; height, six feet, or nearly; weight, one hundred and seventy-five pounds, approximate; figure good; square shoulders, military air; features, regular; thin lipped; chin sharply pointed; wears at times heavy beard, at others moustache and goatee; eyes dark, called black; hair same, heavy, and sometimes worn quite long; hands well kept, with long slender fingers; speaks English perfectly, accomplished, etc.; a small triangular scar upon temple close to roots of hair. Known to have been in Paris and London in early winter, and to have crossed to New York about January 1st. Returned to Paris some time in March, and crossed last to New York in early May by steamer Normandie.'

'Well,' had been Dave's comment as we reperused this summary of M. Delbras, 'he may disguise himself in many ways, but he can't change his height very much, nor the colour of his eyes, nor his "regular features"'—Dave's features were not strictly regular, and it was a weakness of his always to resent this descriptive phrase—'nor his slim fingers, nor the scar on his temple close to the roots of the hair.'

We had spent a long morning in the rooms of the Secret Service Bureau, and as we were about to take leave, with but a step between us and the outer door, it was hastily opened and a guard entered, followed by two people whom I recognised as Farmer and Mrs. Camp. With a backward step and a quick glance at Dave, I turned and deliberately seated myself.

The only occupants of the outer office at the moment of their entry were the officer in command, who had just accompanied us from the inner office, and the subordinate who was in charge of this outer office, where complaints were received and first hearings granted.

I had drawn back quickly, but the eye of Mrs. Camp was still keen, though she looked a trifle subdued.

'The good land!' she ejaculated, catching at her husband's arm. 'Here's one of 'em now, Camp! They've caught him, anyhow!'
