The tulip-growing world, however, was thrown by it into a state of most active commotion.Some fanciers caught at the idea without believing it practicable, but such is the power of imagination among florists, that although considering the undertaking as certain to fail, all their thoughts were engrossed by that great black tulip, which was looked upon to be as chimerical as the black swan of Horace or the white raven of French tradition.
Van Baerle was one of the tulip-growers who were struck with the idea; Boxtel thought of it in the light of a speculation.Van Baerle, as soon as the idea had once taken root in his clear and ingenious mind, began slowly the necessary planting and cross-breeding to reduce the tulips which he had grown already from red to brown, and from brown to dark brown.
By the next year he had obtained flowers of a perfect nut-brown, and Boxtel espied them in the border, whereas he had himself as yet only succeeded in producing the light brown.
It might perhaps be interesting to explain to the gentle reader the beautiful chain of theories which go to prove that the tulip borrows its colors from the elements; perhaps we should give him pleasure if we were to maintain and establish that nothing is impossible for a florist who avails himself with judgment and discretion and patience of the sun's heat; the clear water, the juices of the earth, and the cool breezes.But this is not a treatise upon tulips in general; it is the story of one particular tulip which we have undertaken to write, and to that we limit ourselves, however alluring the subject which is so closely allied to ours.
Boxtel, once more worsted by the superiority of his hated rival, was now completely disgusted with tulip-growing, and, being driven half mad, devoted himself entirely to observation.
The house of his rival was quite open to view; a garden exposed to the sun; cabinets with glass walls, shelves, cupboards, boxes, and ticketed pigeon-holes, which could easily be surveyed by the telescope.Boxtel allowed his bulbs to rot in the pits, his seedlings to dry up in their cases, and his tulips to wither in the borders and henceforward occupied himself with nothing else but the doings at Van Baerle's.He breathed through the stalks of Van Baerle's tulips, quenched his thirst with the water he sprinkled upon them, and feasted on the fine soft earth which his neighbour scattered upon his cherished bulbs.
But the most curious part of the operations was not performed in the garden.
It might be one o'clock in the morning when Van Baerle went up to his laboratory, into the glazed cabinet whither Boxtel's telescope had such an easy access; and here, as soon as the lamp illuminated the walls and windows, Boxtel saw the inventive genius of his rival at work.
He beheld him sifting his seeds, and soaking them in liquids which were destined to modify or to deepen their colours.He knew what Cornelius meant when heating certain grains, then moistening them, then combining them with others by a sort of grafting, -- a minute and marvellously delicate manipulation, -- and when he shut up in darkness those which were expected to furnish the black colour, exposed to the sun or to the lamp those which were to produce red, and placed between the endless reflections of two water-mirrors those intended for white, the pure representation of the limpid element.
This innocent magic, the fruit at the same time of child-like musings and of manly genius -- this patient untiring labour, of which Boxtel knew himself to be incapable -- made him, gnawed as he was with envy, centre all his life, all his thoughts, and all his hopes in his telescope.
For, strange to say, the love and interest of horticulture had not deadened in Isaac his fierce envy and thirst of revenge.Sometimes, whilst covering Van Baerle with his telescope, he deluded himself into a belief that he was levelling a never-failing musket at him; and then he would seek with his finger for the trigger to fire the shot which was to have killed his neighbour.But it is time that we should connect with this epoch of the operations of the one, and the espionage of the other, the visit which Cornelius de Witt came to pay to his native town.
