Cobblestone
From Free net encyclopedia
Cobblestones are stones used in the pavement of early streets. Smooth stones were usually taken from riverbeds and cobbled (roughly assembled) together with mortar. While this removed the mud and dust from dirt roads, it was also quite loud with carriage wheels and horse hooves.

However, cobblestones are often retained in historic areas, even for streets with vehicular traffic.
Greenfield Potatoes is a local term for cobblestones in Arroyo Seco, California. They are 3-4 inch cobblestones that resemble potatoes in size and appearance and which absorb heat during the day and radiate their heat after sunset. They also promote excellent drainage.
