It was evening. Madame de Groot was bending over the stove, cooking her husband's frugal supper. Elsje went in search of the children, to put such of them to bed as were not already there.
Her favourite out of all the little ones was Cornelia, a lovely little girl of nine years, wonderfully like her father, and perfectly devoted to him. She and her brother Hugo were often to be found in the room in which he studied and wrote from morning to night, only varying his sedentary pursuits by the spinning of a huge top that had been made for him by friends in Gorcum, that he might not suffer too greatly from lack of accustomed exercise.
Elsje stole softly into the room, so as not to disturb her master, and glanced round the bare place again and again. Where could the children be? She had looked everywhere else in their limited quarters; there was no other room except this one that had not been searched through and through. She would not disturb her master by a question, and continued softly moving and looking about, till the sound of a suppressed child's laugh, close beside her, made her almost jump; for there was nothing to be seen, save—ah! yes; she saw it all now—there was the great empty chest that had brought the last load of books from Gorcum. She raised the lid, and a simultaneous shriek of laughter arose from two pairs of rosy child-lips. There were little Cornelia and Hugo, curled up like dormice in the chest, peeping at Elsje, with eyes brimming with laughter.
She carried them off, laughing herself, and asking them how they managed to breathe with the heavy lid closed fast down.
"Oh, there is a long crack just under the top of the lid, it doesn't show from outside; but we could see light, and your shadow came right over us, and then Hugo laughed, and you heard. We sat there a long time this afternoon and told ghost stories. It was such fun!"
Elsje put the children to bed, and went thither shortly herself, but all the night long she was dreaming, dreaming, dreaming. She saw the chest with the two children inside; and then she saw it again, and instead of two small figures there was one large one—a tall man's figure crushed together in the chest, and when he turned his face towards her it was the face of her master!
The girl was up and about with the dawn; and her mistress coming to help her, she told her in whispers of the incident of the previous night and of her dream, and the two women stood staring at each other, with white faces and glowing eyes, as the idea slowly formulated itself and took shape.
"It might be done! It might be done!" whispered Madame de Groot at last; "if he could get in, it might perchance be done. Oh! if heaven should open us such a way as that!"
That day passed like a dream to all. They waited till dark; till all the children were sound asleep, and no one from without would trouble them again, before they even dared to make the experiment. Grotius was a tall man, as has been said, though he was slender in his proportions. At another time he would have pronounced it impossible that he should so fold himself up as to get inside that chest, and let the lid be fastened down upon him. But when a man sees life-long captivity before him on the one side, and the hope of escape and freedom on the other, he can sometimes achieve the impossible. And, at last, after many efforts, the thing was done; the lid was closed, and the man found that he could breathe and endure the pressure even for a considerable period.
Day by day, or, rather, night by night, he made these trials till his limbs in some sort grew accustomed to the strange constriction, and he was able to bear the cramped posture for a more prolonged time. Madame de Groot, upon her next journey into Gorcum, spoke jestingly with a friend as to how her husband would be received were he to turn-up some day, and Madame Daatselaer answered, in the same jesting spirit, that he would have a warm and hearty welcome; for the Daatselaers were old and tried friends, though only of the rank of merchants. They owned a large warehouse of great repute, and their dwelling-house was at the rear of the shop, where ribbons and other merchandise were vended to all comers.
