Jack often managed to get off some such yarn when the necessity arose for keeping the talkative Perk from “spilling the beans,” as the latter himself would have explained it—Perk was a rather simple minded fellow, taken in all, but a faithful and sincere chum, a ready worker, and as brave as they make them, even if a bit incautious, often to recklessness in his actions.

It seemed as though there were more people dining that evening in the particular little restaurant than ever before: but Joe had upturned two chairs at their favorite corner table, toward which Jack led the way; so they were assured of comfort, even though late-comers were standing, awaiting their turn.

Both of them always made it a point never to dress in any fashion such as would be apt to give away the fact of their being airmen, or as having some connection with the following of aviators. This was done from a broad policy, founded on the fact that undoubtedly rumors of their calling might long ere this have posted criminal circles; and Jack for one had no fancy about having gunmen dogging his steps, with murder in their hearts, because of the fact that this pair of “birds” had been chiefly instrumental in sending some pal, or brother, to the “big house” for a long stay, or it might be to the chair to atone for his crimes.

Jack always sat so he could look in careless fashion around the room. His manner was that of a social fellow, taking an inventory of the diners, as though wondering if he could single out some crony. There was nothing of the “eagle eye that could look into a man’s very soul, and read his hidden thoughts,” as usually connected with the mystery story, or stage detective—not about Jack, or for that matter Perk either—so far as outward appearances went they were only a couple of goodnatured young men, smiling and agreeable, enjoying their meal, and chatting about the latest stirring events of the day in the field of sports, possibly also interested in political matters, as would be natural.

Perk always declared he felt as though he had put on a mask, when thus debarred from “talking shop,” with curious ears so close by; but he realized the necessity for such extreme caution, when they were always pitted against the desperadoes of the underworld in their daily work.

“Somethin’ o’ a mob here tonight, partner?” suggested Perk, after they had been served by Joe, the waiter, and taken the edge off their appetites; both having settled on the same aromatic dish, which Perk was savagely attacking.

“Looks that way, Perk; if this keeps on we’ll have to find another place to feed, when we strike San Diego again; since neither of us is partial to crowds. Remember the old frontiersman who complained that the neighborhood was getting too thickly settled for him and his folks, because a new family had started to build a log cabin less than seven miles away? People look at what makes a crowd with different viewpoints, we have to remember; what is flesh to one is just poison to another man.”

“Huh! never heard tell o’ that idear ’fore,” confessed the interested Perk; “but it rings like there might be somethin’ in the same. See anybody yeou happens to know ’round here partner?”

“Not one that I would be apt to speak to,” Jack told him; “of course we see some of them each night; but they’ve paid no attention to us, for which we’re only too glad; doesn’t pay to pick up chance acquaintances at haphazard, when you happen to be engaged in a certain type of business. If you reckon you’ve attended to that vacuum downstairs we might as well be moving out, and give some of the standup people a chance at this table.”

“Let’s get goin’ then,” agreed Perk, pushing back his chair; which action caused several groups of impatient waiting persons to start toward the spot, so as to preempt the vacant table.
