She did at last extort from her father an acknowledgment that the horses were engaged. Jane was therefore obliged to go on horseback, and her mother attended her to the door with many cheerful prognostics of a bad day. Her hopes were answered; Jane had not been gone long before it rained hard. Her sisters were uneasy for her, but her mother was delighted. The rain continued the whole evening without intermission; Jane certainly could not come back.
"This was a lucky idea of mine, indeed!" said Mrs. Bennet more than once, as if the credit of making it rain were all her own. Till the next morning, however, she was not aware of all the felicity of her contrivance. Breakfast was scarcely over when a servant from Netherfield brought the following note for Elizabeth:
"MY DEAREST LIZZY,--
"I find myself very unwell this morning, which, I suppose, is to be imputed to my getting wet through yesterday. My kind friends will not hear of my returning till I am better. They insist also on my seeing Mr. Jones--therefore do not be alarmed if you should hear of his having been to me--and, excepting a sore throat and headache, there is not much the matter with me.--Yours, etc."
"Well, my dear," said Mr. Bennet, when Elizabeth had read the note aloud, "if your daughter should have a dangerous fit of illness--if she should die, it would be a comfort to know that it was all in pursuit of Mr. Bingley, and under your orders."
"Oh! I am not afraid of her dying. People do not die of little trifling colds. She will be taken good care of. As long as she stays there, it is all very well. I would go and see her if I could have the carriage."
