She was able to remember without fail which color represented, for example, the wrist or the ankle measurement, because this fat and slightly grey and ignorant peasant woman had a better sense of recollection than any of the caste of learned and educated men. These colored ribbons were then carefully sewn together so that they made a long string with which Katerina was taking her measurements. In this way, a practical yardstick of Nelidowa's proportions was procured. How often she had tried in vain! First she had gone around to the households of other Grandees, and after a friendly chat with the Major Domo or with the head housekeeper, she had looked the serf girls over, because it was always possible to buy a certain girl if no special reasons kept her in the household such as the master liking her best as a bed companion. But not even among the ladies' maids and linen girls, who were supposed to be of the finest kind, could she find any who came near her measurements. Then she had gone to the serf markets, which were held from time to time to make exchanges of serfs in the different houses of the aristocracy. After that, she had visited what one would call dealers, certain persons who had once been major domos and were liberated for one reason or another, and who made a scanty commission buying and selling serfs, mostly young, good looking girls who were traded to the many whorehouses which at that time began to flourish in Moscow, a fashion lately imported from Paris. In this way, Katerina had been hunting the whole winter, and while she found here and there a girl who came near the requirements, she had been told to bring a girl who would fit exactly. But how to get her? All this was on Katerina's mind on that April afternoon (it must have been, approximately, in the year 1728) while she was on her way to a private dealer in the poor quarters of the north of Moscow.
