The route, too, was a new one. From Gorgona the train returned crab-wise through Matachin and across the sand dyke that still holds the Chagres out of the "cut," and halted at Gamboa cabin. Day was dying as we rumbled on across the iron bridge above the river and away into the fresh jungle night along the rock-ballasted "relocation." The stillness of this less inhabited half of the Zone settled down inside the car and out, the evening air of summer caressing almost roughly through the open windows. The train continued its steady way almost uninterruptedly, for though new villages were springing up to take the place of the old sinking into desuetude and the flood along with the abandoned line, there were but two where once were eight. We paused at the new Frijoles and the box-car town of Monte Lirio and, skirting on a higher level with a wide detour on the flanks of thick jungled and forested hills what is some day to be Gatun Lake, drew up at 7:30 at Gatun.

I wandered and inquired for some time in a black night—for the moon was on the graveyard shift that week—before I found Gatun police station on the nose of a breezy knoll. But for "Davie," the desk-man, who it turned out was also to be my room-mate, and a few wistful-eyed negroes in the steel-barred room in the center of the building, the station was deserted. "Circus," said the desk-man briefly. When I mentioned the matter of weapons he merely repeated the word with the further information that only the station commander could issue them.

There was nothing to do therefore but to ramble out armed with a lead pencil into a virtually unknown town riotous with liquor and negroes and the combination of Saturday night, circus time, and the aftermath of pay-day, and to strut back and forth in a way to suggest that I was a perambulating arsenal. But though I wandered a long two hours into every hole and corner where trouble might have its breeding-place, nothing but noise took place in my sight and hearing. I turned disgustedly away toward the tents pitched in a grassy valley between the two Gatuns. At least there was a faint hope that the equestrienne might assault the ring-master.

I approached the tent flap with a slightly quickening pulse. World-wide and centuries old as is the experience, personally I was about to "spring my badge" for the first time. Suppose the doortender should refuse to honor it and force me to impress upon him the importance of the Z. P.—without a gun? Outwardly nonchalant I strolled in between the two ropes. Proprietor Shipp looked up from counting his winnings and opened his mouth to shout "ticket!" I flung back my coat, and with a nod and a half-wink of wisdom he fell back again to computing his lawful gains.

By the way, are not you who read curious to know, even as I for long years wondered, where a detective wears his badge? Know then that long and profound investigation among the Z. P. seems to prove conclusively that as a general and all but invariable rule he wears it pinned to the lining of his coat, or under his lapel, or on the band of his trousers, or on the breast of his shirt, or in his hip pocket, or up his sleeve, or at home on the piano, or riding around at the end of a string in the baby's nursery; though as in the case of all rules this one too has its exceptions.

Entertainments come rarely to Gatun. The one-ringed circus was packed with every grade of society from gaping Spanish laborers to haughty wives of dirt-train conductors, among whom it was not hard to distinguish in a far corner the uniformed sergeant in command of Gatun and the long lean corporal tied in a bow-line knot at the alleged wit of the versatile but solitary clown who changed his tongue every other moment from English to Spanish. But the end was already near; excitement was rising to the finale of the performance, a wrestling match between a circus man and "Andy" of Pedro Miguel locks. By the time I had found a leaning-place it was on—and the circus man of course was conquered, amid the gleeful howling of "rough-necks," who collected considerable sums of money and went off shouting into the black night, in quest of a place where it might be spent quickly. It would be strange indeed if among all the thousands of men in the prime of life who are digging the canal at least one could not be found who could subjugate any champion a wandering circus could carry among its properties. I took up again the random tramping in the dark unknown night; till it was two o'clock of a Sunday morning when at last I dropped my report-card in the train-guard box and climbed upstairs to the cot opposite "Davie," sleeping the silent, untroubled sleep of a babe.

I was barely settled in Gatun when the train-guard handed me one of those frequent typewritten orders calling for the arrest of some straggler or deserter from the marine camp of the Tenth Infantry. That very morning I had seen "the boss" of census days off on his vacation to the States—from which he might not return—and here I was coldly and peremptorily called upon to go forth and arrest and deliver to Camp Elliott on its hill "Mac," the pride of the census, with a promise of $25 reward for the trouble. "Mac" desert? It was to laugh. But naturally after six weeks of unceasing repetition of that pink set of questions "Mac's" throat was a bit dry and he could scarcely be expected to return at once to the humdrum life of camp without spending a bit of that $5 a day in slaking a tropical thirst. Indeed I question whether any but the prudish will loudly blame "Mac" even because he spent it a bit too freely and brought up in Empire dispensary. Word of his presence there soon drifted down to the wily plain-clothes man of Empire district. But it was a hot noonday, the dispensary lies somewhat up hill, and the uniformless officer of the Zone metropolis is rather thickly built. Wherefore, stowing away this private bit of information under his hat, he told himself with a yawn, "Oh, I'll drag him in later in the day," and drifted down to a wide-open door on Railroad Avenue to spend a bit of the $25 reward in off-setting the heat. Meanwhile "Mac," feeling somewhat recovered from his financial extravagance, came sauntering out of the dispensary and, seeing his curly-headed friend strolling a beat not far away, naturally cried out, "Hello, Eck!" And what could Eck say, being a reputable Zone policeman, but:

"Why, hello, Mac! How they framin' up? Consider yourself pinched."

Which was lucky for "Mac." For Eck had once worn a marine hat over his own right eye and, he knew from melancholy experience that the $25 was no government generosity, but "Mac's" own involuntary contribution to his finding and delivery; so managed to slip most of it back into "Mac's" hands.

Long, long after, more than six weeks after in fact, I chanced to be in Bas Obispo with a half-hour to spare, and climbed to the flowered and many-roaded camp on its far-viewing hilltop that falls sheer away on the east into the canal. In one of the airy barracks I found Renson, cards in hand, clear-skinned and "fit" now, thanks to the regular life of this adult nursery, though his lost youth was gone for good. And "Mac"? Yes, I saw "Mac" too—or at least the back of his head and shoulders through the screen of the guard-house where Renson pointed him out to me as he was being locked up again after a day of shoveling sand.
