Mill The Moynihan family operated a water mill fed by a sluice from the Durrus River, starting at the Creamery and continuing to the Mill. It had extensive use during the Second World War. Moynihan was the headmaster in the school. In the 19th century there was also a scutch mill listed in Griffiths Valuations. Markets and fairs In 1912, butter markets operated on Wednesdays and Fridays near the present creamery. The main market was in Bantry with fair day the first Friday each month. The pig fair was held on a Thursday. In the early 20th century, Bantry celebrated the fourth largest fair in Ireland. The railway ran as many as eight carriages to carry cattle and pigs to Cork. The annual horse fair was Ballibui in August in Dunmanway. When the marts started, especially Bandon and Skibbereen (started by Cork Co-Operative Marts in 1958) it sounded the death knell of the cattle fair. Durrus Fair held near Creamery and was revived in 1937 after 20 years. Dairy and creamery By the mid-18th century, the dairy trade in the area sent butter to the Cork market, but the round trip by horse-drawn cart from Skibbereen could take eight days. In the 1730s, Cork merchants came to Bantry every summer, primarily in connection with the pilchard trade, but also to export butter. In addition, farmers and car men faced the hazards of highwaymen. Many did not use carts. This was evidenced by Sir John Carr in 1805, who wrote "peasants with horses carrying barrels of butter to Cork secured as usual with ropes of hay" and Sir Richard Colt Hoare in 1806, who said "numerous troops of pack horses conveying casks of salt butter from the interior to Cork". Patrick and Andrew Gallwey of Bantry wrote in 1737 that the small cows in the district would have produced from half to two-thirds of a hundredweight of butter per annum. In the post-famine era, with consolidation of holdings and the collapse of grain prices with the passing of the Corn Laws, dairying assumed greater importance. The merchants would receive butter in amounts of 20 or and salt and make it up to , the measure of a firkin, they would pay the same as applied in the Cork Butter Market. The railway reduced the time to take butter to
