Mr Watkins was apparently unaware of his approach. A friendly conversation with Lady Hammerpond's butler had just terminated, and that individual, surrounded by the three pet dogs which it was his duty to take for an airing after dinner had been served, was receding in the distance. Mr Watkins was mixing colour with an air of great industry. Sant, approaching more nearly, was surprised to see the colour in question was as harsh and brilliant an emerald green as it is possible to imagine. Having cultivated an extreme sensibility to colour from his earliest years, he drew the air in sharply between his teeth at the very first glimpse of this brew. Mr Watkins turned round. He looked annoyed. "What on earth are you going to do with that _beastly_ green?" said Sant. Mr Watkins realised that his zeal to appear busy in the eyes of the butler had evidently betrayed him into some technical error. He looked at Sant and hesitated. "Pardon my rudeness," said Sant; "but really, that green is altogether too amazing. It came as a shock. What _do_ you mean to do with it?" Mr Watkins was collecting his resources. Nothing could save the situation but decision. "If you come here interrupting my work," he said, "I'm a-goin' to paint your face with it." Sant retired, for he was a humourist and a peaceful man. Going down the hill he met Porson and Wainwright. "Either that man is a genius or he is a dangerous lunatic," said he. "Just go up and look at his green." And he continued his way, his countenance brightened by a pleasant anticipation of a cheerful affray round an easel in the gloaming, and the shedding of much green paint. But to Porson and Wainwright Mr Watkins was less aggressive, and explained that the green was intended to be the first coating of his picture. It was, he admitted in response to a remark, an absolutely new method, invented by himself. But subsequently he became more reticent; he explained he was not going to tell every passer-by the secret of his own particular style, and added some scathing remarks upon the meanness of people "hanging about" to pick up such tricks of the masters as they could, which immediately relieved him of their company. Twilight deepened, first one then another star appeared. The rooks amid the tall trees to the left of the house had long since lapsed into slumbrous silence, the house itself lost all the details of its architecture and became a dark grey outline, and then the windows of the salon shone out brilliantly, the conservatory was lighted up, and here and there a bedroom window burnt yellow. Had anyone approached the easel in the park it would have been found deserted. One brief uncivil word in brilliant green sullied the purity of its canvas. Mr Watkins was busy in the shrubbery with his assistant, who had discreetly joined him from the carriage-drive.
