Which is among the various reasons why it was without protest that, with "the Captain's" telephoned consent on the ground that I was now virtually on the force, I took up my residence in Corozal police station. 'T is a peaceful little building of the usual Zone type on a breezy knoll across the railroad, with a spreading tree and a little well-tended flower plot before it, and the broad world stretching away in all directions behind. Here lived Policeman T---- and B----. "First-class policemen" perhaps I should take care to specify, for in Zone parlance the unqualified noun implies African ancestry. But it seems easier to use an adjective of color when necessary. Among their regular duties was that of weighing down the rocking-chairs on the airy front veranda, whence each nook and cranny of Corozal was in sight, and of strolling across to greet the train-guard of the seven daily passengers; though the irregular ones that might burst upon them at any moment were not unlikely to resemble a Moro expedition in the Philippines. B---- and I shared the big main room; for T----, being the haughty station commander, occupied the parlor suite beside the office. That was all, except the black Trinidadian boy who sat on the wooden shelf that was his bed behind a huge padlocked door and gazed dreamily out through the bars--when he was not carrying a bundle to the train for his wardens or engaged in the janitor duties that kept Corozal station so spick and span. Oh! To be sure there were also a couple of negro policemen in the smaller room behind the thin wooden partition of our own, but negro policemen scarcely count in Zone Police reckonings. "By Heck! They must use a lot o' mules t' haul aout all thet dirt," observed an Arkansas farmer to his nephew, home from the Zone on vacation. He would have thought so indeed could he have spent a day at Corozal and watched the unbroken deafening procession of dirt-trains scream by on their way to the Pacific,--straining Moguls dragging a furlong of "Lidgerwood flats," swaying "Oliver dumps" with their side chains clanking, a succession as incessant of "empties" grinding back again into the midst of the fray. On the tail of every train lounged an American conductor, dressed more like a miner, though his "front" and "hind" negro brakemen were as apt to be in silk ties and patent-leathers. To say nothing of the train-loads that go Atlanticward and to jungle "dumps" and to many an unnoticed "fill." Then when he had thus watched the day through it would have been of interest to go and chat with some of the "Old Timers" who live here beside the track and who have seen, or at least heard, this same endless stream of rock and earth race by six days a week, fifty-two weeks a year for six years, as constant and heavily-laden to-day as in the beginning. He might discover, as not all his fellow-countrymen have as yet, that the little surgical operation on Mother Earth we are engaged in is no mule job.
