my eyes caught the startling words;—"Unless you are sure you are a man of physical appearance far above the average do not fill out this application."

I was suddenly aware of a sinking feeling in the pit of my stomach; the blank all but slipped from my nerveless fingers. Then all at once there came back to me the words of some chance acquaintance of some far-off time and place, words which were the only memory that remained to me of the speaker, except that he had lived long and gathered much experience, "Bluff, my boy, is what carries a man through the world. Act as if you're sure you are and can and you'll generally make the other fellow think so." I sat down at a desk and filled out the application in my most self-confident flourish.

"Go to Culebra to-morrow," said the Inspector, as I bade the room good-day and stepped forth with my most military stride and bearing, "and report back here Friday morning."

I descended to the world below, not by the long perspective of stairs that leads down and across the gully to the heart of Ancon, but by a short-cut that took me quickly into a foreign land. The graveled highway at the foot of the hill I might not have guessed was an international boundary had I not chanced to notice the instant change from the trim, screened Zone buildings, each in its green lawn, to the featureless architecture of a city where grass is all but unknown; for the formalities of crossing this frontier are the same as those of crossing any village street. It was my first entrance into the land of the panamenos, technically known on the Zone as "Spigoties," and familiarly, with a tinge of despite, as "Spigs"; because the first Americans to arrive in the land found a few natives and cabmen who claimed to "Speaga dee Eng-leesh."

To Americans direct from the States Panama city ranks still as rather a miserable dawdling village. But that is due chiefly to lack of perspective. Against the background of Central America it seemed almost a great, certainly a flourishing, city. Even to-day there are many who complain of its unpleasant odors; to those who have lived in other tropical cities its scent is like the perfumes of Araby; and none but those can in any degree realize what "Tio Sam" has done for the place.

Toward sunset I passed through a gateway with scores of fellow-countrymen, all as composedly at home as in the heart of their native land. Across the platform stood a train distinctively American in every feature, a bilious-yellow train divided by the baggage car into two sections, of which the five second-class coaches behind the engine, with their wooden benches, were densely packed in every available space with workmen and laborer's wives, from Spaniards to ebony negroes, with the average color decidedly dark. In the first-class cars at the Panama end were Americans, all but exclusively white Americans, with only here and there a "Spigoty" with his long greased hair, his finger rings, and his effeminate gestures, and even a negro or two. For though Uncle Sam may permit individual states to do so, he may not himself openly abjure before the world his assertion as to the equality of all men by enacting "Jim Crow" laws.

We were soon off. Settled back in the ample seat of the first real train I had boarded in months, with the roar of its length over the smooth and solid road-bed, the deep-voiced, masculine whistle instead of the painful, puerile screech that had recently assailed my ear, I all but forgot I was in a foreign land. The fact was recalled by the passing of the train-guard,—an erect and self-possessed young American in "Texas" hat, khaki uniform, and leather leggings, striding along the aisle with a jerking, half-arrogant swing of the shoulders. So, perhaps, might I too soon be parading across the Isthmus! It was not, to be sure, exactly the role I had planned to play on the Zone. I had come rather with the hope of shouldering a shovel and descending into the canal with other workmen, that I might some day solemnly raise my right hand and boast, "I helped dig IT." But that was in the callow days before I had arrived and learned the awful gulf that separates the sacred white American from the rest of the Canal Zone world. Besides, had I not always wanted to be a policeman and twirl a club and stalk with heavy, law-compelling tread ever since I had first stared speechless upon one of those noble beings on my first trip out into the world twenty-one years before?

It was not without effort that I rose in time next morning to continue on the 6:37 from Corozal across another bit of the Zone. Exactly thus should one first see the Great Work, piece-meal, slowly; unless he will go home with it all in an undigested lump. The train rolled across a stretch of almost uninhabited country, with a vast plain of broken rock on the right, plunged unexpectedly through a short tunnel, and stopped at a station perched on the edge of a ridge above a small Zone town backed by some vast structure, above which here and there a huge crane loomed against the sky of dawn. Another mile and the collectors were announcing as brazenly as if they challenged the few "Spigs" on board to correct them, "Peter M'Gill! Peter M'Gill!" We were already moving on again before I had guessed that by this noise they designated none other than the famous Pedro Miguel. The sun rose suddenly as we swung sharply to the left and rumbled across a girderless bridge. Barely had I time to discover that we were crossing the great canal itself and to catch a brief glimpse of the jagged gulf in either direction, before the train had left it behind, as if the sight of the world-famous channel were not worth a pause, and was roaring on through a hilly country of perpetual summer. A peculiarly shaped reservoir sped past on the left, twice or thrice more the green horizon rose and fell, and at 7:30 we drew up at the base of Culebra, the Zone capital.

On the screened veranda of a somewhat sooty and dismal building high up near the summit of the town, another and I were pacing anxiously back and forth when, well on in the morning, an abrupt and rather gloomy-faced American dashed into the building and one of the rooms thereof, snapping over his shoulder as he disappeared, "One of you!" The other had precedence. Then soon from behind the wooden shutters came a growl of "Next!" and two moments later I was standing in the reputed costume of Adam on the scales within. At about ten-second intervals a monosyllable fell from the lips of the morose American as he delved into my personal make-up from crown to toe with all the instrumental circumspection known to his secret-discovering profession. Then with a gruff "Dress!" he sat down at a table to scratch a few fantastic marks on the blank I had brought, and hand it to me as I caught up my last garment and turned to the door. But, alas—tight sealed! and all the day, though carrying the information in my pocket, I must live in complete ignorance of whether I had been found lacking an eye or a lung. For sooner would one have asked his future of the scowling Parques than venture to invoke a hint thereof from that furrow-browed being from the Land of Bruskness.

Meanwhile, as if it had been thus planned to give me such opportunity, I stood at the very vortex of canal interest and fame, with nearly an entire day before the evening train should carry me back to Corozal. I descended to the "observation platform." Here at last at my very feet was the famous "cut" known to the world by the name of Culebra; a mighty channel a furlong wide plunging sheer through "Snake Mountain," that rocky range of scrub-wooded hills; severing the continental divide. At first view the scene was bewildering. Only gradually did the eye gather details out of the mass. Before and beyond were pounding rock drills, belching locomotives, there arose the rattle and bump of long trains of flat-cars on many tracks, the crash of falling boulders, the snort of the straining steam-shovels heaping the cars high with earth and rock, everywhere were groups of little men, some working leisurely, some
