Aesop's Fables (1884)
30. The Milkmaid and her Pot of Milk.
A Maid was carrying her pail of milk to the farm-house, when she fell a-musing. "The money for which this milk will be sold will buy at least three hundred eggs. The eggs, allowing for all mishaps, will produce two hundred and fifty chickens. The chickens will become ready for market when poultry will fetch the highest price; so that by the end of the year I shall have money enough to buy a new gown. In this dress I will go to the Christmas junketings, when all the young fellows will propose to me, but I will toss my head, and refuse them every one." At this moment she tossed her head in unison with her thoughts, when down fell the Milk-pot to the ground, and broke into a hundred pieces, and all her fine schemes perished in a moment.
Count not your chickens before they are hatched.
