The Scott & Daisy Pits were adjoining coal workings on the banks of the River Blyth, around half a mile between St Marys Church and West Hartford Hall. It was sunk and opened around 1867, as advertisements were rolled out to newspapers for the "new works at Hartford Colliery". It was operated by the Cramlington Coal Co., beforehand owned by the Lambs from the outset, who were better known at this stage for their glass enterprise in Lemington.

It was faced with difficulty in the first decade. In 1877, 120 of the men alongside some of the boys led the colliery idle, and drew up the ponies in the January. The slump in the coal trade meant work was far more scant given the sheer scale of coal mining in the area, and many had to rely on the small bursary fund from the Miners Association. The same occurred at Seghill, Dudley and the Shankhouse Colliery. After this however it was one of the most successful.

Our first view of the pit comes in the 1890s. Over the couple decades prior a small village developed alongside the pit, consisting of a double row, a post office row and two small single rows featuring a smithy. It was connected to the Cramlington Colliery Railway with an extension from Shankhouse, allowing further shipment to the staiths on the Tyne. It was also one of the most distinctive in the region, with a buttressed structure housing the shaft like a giant warehouse or hangar.

By the turn of the century around 700 people worked at the Scott & Daisy pit, with 550 of those underground. The Scott worked the High & Low Main, the Plessey Seam, the Stone Coal seam and the Yard seam while the Daisy worked the Five Quarter, High, Plessey, Yard, Stone Coal and the Low Main. All coal was suitable traded for steam and fireclay use for brick making. It reached its peak in the 20s, with just under 1000 working there.

The pit village also grew significantly much to the appearance it is now. By the mid 20th century it featured a Methodist church, a Roman Catholic iteration, hotel, two institutes, a primary school and a recreation ground. Some of these features still exist.

The colliery closed in 1961. There's little indicator of the pit today.
