What is "buttermen"

Usage examples of "buttermen".

In like sort, since the number of buttermen have so much increased, and since they travel in such wise that they come to men's houses for their butter faster than they can make it, it is almost incredible to see how the price of butter is augmented: whereas when the owners were enforced to bring it to the market towns, and fewer of these butter buyers were stirring, our butter was scarcely worth eighteen pence the gallon that now is worth three shillings fourpence and perhaps five shillings.
