Kirkwood chuckled to recall how, all unwittingly, he had been the means of diverting from her chosen course that acute and resourceful lady; then again turned his attention to the tables.

A third check had been placed against the train for Amsterdam scheduled to leave Antwerp at 6:32 p. m. Momentarily his heart misgave him, when he saw this, in fear lest Calendar and Dorothy should have gone on from Antwerp the previous evening; but then he rallied, discovering that the boat-train from Flushing did not arrive at Antwerp till after ten at night; and there was no later train thence for Amsterdam. Were the latter truly their purposed destination, they would have stayed overnight and be leaving that very evening on the 6:32. On the other hand, why should they wait for the latest train, rather than proceed by the first available in the morning? Why but because Calendar and Mulready were to wait for Stryker to join them on the Alethea?

Very well, then; if the wind held and Stryker knew his business, there would be another passenger on that train, in addition to the Calendar party.

Making mental note of the fact that the boat-train for Flushing and London was scheduled to leave Antwerp daily at 8:21 p. m., Kirkwood rustled the leaves to find out whether or not other tours had been planned, found evidences of none, and carefully restored the guide to the locker, lest inadvertently the captain should pick it up and see what Kirkwood had seen.

An hour later he went on deck. The skies had blown clear and the brigantine was well in land-bound waters and still footing a rattling pace. The river-banks had narrowed until, beyond the dikes to right and left, the country-side stretched wide and flat, a plain of living green embroidered with winding roads and quaint Old-World hamlets whose red roofs shone like dull fire between the dark green foliage of dwarfed firs.

Down with the Scheldt's gray shimmering flood were drifting little companies of barges, sturdy and snug both fore and aft, tough tanned sails burning in the afternoon sunlight. A long string of canal-boats, potted plants flowering saucily in their neatly curtained windows, proprietors expansively smoking on deck, in the bosoms of their very large families, was being mothered up-stream by two funny, clucking tugs. Behind the brigantine a travel-worn Atlantic liner was scolding itself hoarse about the right of way. Outward bound, empty cattle boats, rough and rusty, were swaggering down to the sea, with the careless, independent thumbs-in-armholes air of so many navvies off the job.

And then lifting suddenly above the level far-off sky-line, there appeared a very miracle of beauty; the delicate tracery of the great Cathedral's spire of frozen lace, glowing like a thing of spun gold, set against the sapphire velvet of the horizon.

Antwerp was in sight.

A troublesome care stirring in his mind, Kirkwood looked round the deck; but Stryker was very busy, entirely too preoccupied with the handling of his ship to be interrupted with impunity. Besides, there was plenty of time.

More slowly now, the wind falling, the brigantine crept up the river, her crew alert with sheets and halyards as the devious windings of the stream rendered it necessary to trim the canvas at varying angles to catch the wind.
