All at once, Cornelius van Baerle, who, after all his learned pursuits, had been seized with the tulipomania, made some changes in his house at Dort, which, as we have stated, was next door to that of Boxtel. He raised a certain building in his court-yard by a story, which shutting out the sun, took half a degree of warmth from Boxtel’s garden, and, on the other hand, added half a degree of cold in winter; not to mention that it cut the wind, and disturbed all the horticultural calculations and arrangements of his neighbour. After all, this mishap appeared to Boxtel of no great consequence. Van Baerle was but a painter, a sort of fool who tried to reproduce and disfigure on canvas the wonders of nature. The painter, he thought, had raised his studio by a story to get better light, and thus far he had only been in the right. Mynheer van Baerle was a painter, as Mynheer Boxtel was a tulip-grower; he wanted somewhat more sun for his paintings, and he took half a degree from his neighbour’s tulips. The law was for Van Baerle, and Boxtel had to abide by it. Besides, Isaac had made the discovery that too much sun was injurious to tulips, and that this flower grew quicker, and had a better colouring, with the temperate warmth of morning, than with the powerful heat of the midday sun. He therefore felt almost grateful to Cornelius van Baerle for having given him a screen gratis. Maybe this was not quite in accordance with the true state of things in general, and of Isaac Boxtel’s feelings in particular. It is certainly astonishing what rich comfort great minds, in the midst of momentous catastrophes, will derive from the consolations of philosophy. But alas! What was the agony of the unfortunate Boxtel on seeing the windows of the new story set out with bulbs and seedlings of tulips for the border, and tulips in pots; in short, with everything pertaining to the pursuits of a tulip-monomaniac! There were bundles of labels, cupboards, and drawers with compartments, and wire guards for the cupboards, to allow free access to the air whilst keeping out slugs, mice, dormice, and rats, all of them very curious fanciers of tulips at two thousand francs a bulb. Boxtel was quite amazed when he saw all this apparatus, but he was not as yet aware of the full extent of his misfortune. Van Baerle was known to be fond of everything that pleases the eye. He studied Nature in all her aspects for the benefit of his paintings, which were as minutely finished as those of Gerard Dow, his master, and of Mieris, his friend. Was it not possible, that, having to paint the interior of a tulip-grower’s, he had collected in his new studio all the accessories of decoration?
