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.
