The Rival And in fact the poor young people were in great need of protection.
They had never been so near the destruction of their hopes as at this moment, when they thought themselves certain of their fulfilment.
The reader cannot but have recognized in Jacob our old friend, or rather enemy, Isaac Boxtel, and has guessed, no doubt, that this worthy had followed from the Buytenhof to Loewestein the object of his love and the object of his hatred, -- the black tulip and Cornelius van Baerle.
What no one but a tulip-fancier, and an envious tulip-fancier, could have discovered, -- the existence of the bulbs and the endeavours of the prisoner, -- jealousy had enabled Boxtel, if not to discover, at least to guess.
We have seen him, more successful under the name of Jacob than under that of Isaac, gain the friendship of Gryphus, which for several months he cultivated by means of the best Genievre ever distilled from the Texel to Antwerp, and he lulled the suspicion of the jealous turnkey by holding out to him the flattering prospect of his designing to marry Rosa.
Besides thus offering a bait to the ambition of the father, he managed, at the same time, to interest his zeal as a jailer, picturing to him in the blackest colours the learned prisoner whom Gryphus had in his keeping, and who, as the sham Jacob had it, was in league with Satan, to the detriment of his Highness the Prince of Orange.
At first he had also made some way with Rosa; not, indeed, in her affections, but inasmuch as, by talking to her of marriage and of love, he had evaded all the suspicions which he might otherwise have excited.
We have seen how his imprudence in following Rosa into the garden had unmasked him in the eyes of the young damsel, and how the instinctive fears of Cornelius had put the two lovers on their guard against him.
The reader will remember that the first cause of uneasiness was given to the prisoner by the rage of Jacob when Gryphus crushed the first bulb.In that moment Boxtel's exasperation was the more fierce, as, though suspecting that Cornelius possessed a second bulb, he by no means felt sure of it.
From that moment he began to dodge the steps of Rosa, not only following her to the garden, but also to the lobbies.
Only as this time he followed her in the night, and bare-footed, he was neither seen nor heard except once, when Rosa thought she saw something like a shadow on the staircase.
Her discovery, however, was made too late, as Boxtel had heard from the mouth of the prisoner himself that a second bulb existed.
Taken in by the stratagem of Rosa, who had feigned to put it in the ground, and entertaining no doubt that this little farce had been played in order to force him to betray himself, he redoubled his precaution, and employed every means suggested by his crafty nature to watch the others without being watched himself.
He saw Rosa conveying a large flower-pot of white earthenware from her father's kitchen to her bedroom.He saw Rosa washing in pails of water her pretty little hands, begrimed as they were with the mould which she had handled, to give her tulip the best soil possible.
And at last he hired, just opposite Rosa's window, a little attic, distant enough not to allow him to be recognized with the naked eye, but sufficiently near to enable him, with the help of his telescope, to watch everything that was going on at the Loewestein in Rosa's room, just as at Dort he had watched the dry-room of Cornelius.
He had not been installed more than three days in his attic before all his doubts were removed.
From morning to sunset the flower-pot was in the window, and, like those charming female figures of Mieris and Metzys, Rosa appeared at that window as in a frame, formed by the first budding sprays of the wild vine and the honeysuckle encircling her window.
Rosa watched the flower-pot with an interest which betrayed to Boxtel the real value of the object enclosed in it.
This object could not be anything else but the second bulb, that is to say, the quintessence of all the hopes of the prisoner.
When the nights threatened to be too cold, Rosa took in the flower-pot.
Well, it was then quite evident she was following the instructions of Cornelius, who was afraid of the bulb being killed by frost.
When the sun became too hot, Rosa likewise took in the pot from eleven in the morning until two in the afternoon.
Another proof: Cornelius was afraid lest the soil should become too dry.
But when the first leaves peeped out of the earth Boxtel was fully convinced; and his telescope left him no longer in any uncertainty before they had grown one inch in height.
Cornelius possessed two bulbs, and the second was intrusted to the love and care of Rosa.
For it may well be imagined that the tender secret of the two lovers had not escaped the prying curiosity of Boxtel.
The question, therefore, was how to wrest the second bulb from the care of Rosa.
Certainly this was no easy task.
Rosa watched over her tulip as a mother over her child, or a dove over her eggs.
Rosa never left her room during the day, and, more than that, strange to say, she never left it in the evening.
For seven days Boxtel in vain watched Rosa; she was always at her post.
This happened during those seven days which made Cornelius so unhappy, depriving him at the same time of all news of Rosa and of his tulip.
Would the coolness between Rosa and Cornelius last for ever?
This would have made the theft much more difficult than Mynheer Isaac had at first expected.
