Fifteen years had passed away; the old professor of osteology had passed away with them; and in the large house on the Domplein lived a baron, with half a dozen noisy, happy, healthy children,—­young fraulas and jonkheers,—­who scampered up and down the marble passages, and fell headlong down the steep, narrow, unlighted stairways, to the imminent danger of dislocating their aristocratic little necks.  There was a new race of neat maids, clad in the same neat livery of lilac and black, who scoured and cleaned, just as Koosje and Dortje had done in the old professor’s day.  You might, indeed, have heard the selfsame names resounding through the echoing rooms:  “Koos-je!  Dort-je!”

But the Koosje and Dortje were not the same.  What had become of Dortje I cannot say; but on the left-hand side of the busy, bustling, picturesque Oude Gracht there was a handsome shop filled with all manner of cakes, sweeties, confections, and liquors—­from absinthe to Benedictine, or arrack to chartreuse.  In that shop was a handsome, prosperous, middle-aged woman, well dressed and well mannered, no longer Professor van Dijck’s Koosje, but the Jevrouw van Kampen.

Yes; Koosje had come to be a prosperous tradeswoman of good position, respected by all.  But she was Koosje van Kampen still; the romance which had come to so disastrous and abrupt an end had sufficed for her life.  Many an offer had been made to her, it is true; but she had always declared that she had had enough of lovers—­she had found out their real value.

I must tell you that at the time of Jan’s infidelity, after the first flush of rage was over, Koosje disdained to show any sign of grief or regret.  She was very proud, this Netherland servant-maid, far too proud to let those by whom she was surrounded imagine she was wearing the willow for the faithless Jan; and when Dortje, on the day of the wedding, remarked that for her part she had always considered Koosje remarkably cool on the subject of matrimony, Koosje with a careless out-turning of her hands, palms uppermost, answered that she was right.

Very soon after their marriage Jan and his young wife left Utrecht for Arnheim, where Jan had promise of higher wages; and thus they passed, as Koosje thought, completely out of her life.

“I don’t wish to hear anything more about them, if—­you—­please,” she said, severely and emphatically, to Dortje.

But not so.  In time the professor died, leaving Koosje the large legacy with which she set up the handsome shop in the Oude Gracht; and several years passed on.

It happened one day that Koosje was sitting in her shop sewing.  In the large inner room a party of ladies and officers were eating cakes and drinking chocolates and liquors with a good deal of fun and laughter, when the door opened timidly, thereby letting in a gust of bitter wind, and a woman crept fearfully in, followed by two small, crying children.
