A Gravel Pit; this is not shown on the 2nd edition OS mapping, so was probably out of use by 1895.

Denton Turnpike, on the Newcastle to Carlisle Road (SMR 3945). This is not shown on the 2nd edition OS mapping, so was out of use by 1895.

A Coal Shaft, marked as Old on the 1st edition OS mapping, so was out of use by 1858.

Lime Kilns marked on the 1st edition OS mapping. The number of which is unclear - but it appears to be a battery rather than individual kilns. They are not shown on the 2nd edition OS mapping, so possibly out of use by 1895.

Coke Ovens. This is not shown on the 2nd edition OS mapping, so was probably out of use by 1895.

Lemington Staiths. Lemington was the highest point on the Tyne suitable for staiths and was therefore an important point in the coal transport network. There were staiths here by 1640 and the main 18th century wagonways may still be traced here. Fragmentary timber structures still visible are probably part of the Wylam staiths which were the last to remain in use.

Lemington Glass Works. The works were opened in 1787 by the Northumberland Glass Company. Initially flat glass was produced from 4 large glass cones. In 1906 the site was purchased from the Duke of Northumberland by GEC, who expanded the works and fitted it out for production of light bulbs and tubes. Eventually all but one of the cones was demolished. The remaining one, which stands 120ft high is one of only four such survivals in the country. It was cleaned and repointed in 1993. Local legend has it that the cone was made from 1 million bricks {1}. At one time Spencers took over part of the glassworks site with the intention of developing a steel works, but the project never got off the ground and in 1880 everything was transferred to their main works at Newburn. The glassworks site was leased from the Duke of Northumberland by a group of local businessmen under the name of the Northumberland Glass Company in 1787. This company owned the glassworks until 1837 when three of the glass houses were demolished, leaving the huge cone which is still in existence. From 1833 to 1845 the works were operated by Joseph Lamb and Company but after this date there seems to have been a depression in the glass trade for many years and full scale operations were not carried out until about 1898 when the famous glassmaking firm of George Sowerby and Sons took over and trade picked up, with the result that by 1906 the works were again a prosperous concern {2}.

Lemington Quarry. This is marked as Old on the 2nd edition OS mapping, so was out of use by 1895.

A Flint Mill, in Jesmond Dene, known as Deep Dene or Eliot's High Flint Mill. Little remains of the original mill. Its tailrace discharged to the burn. Site now occupied by Deep Dene House (Fisherman's Lodge restaurant), which was Andrew Noble's first house in the Dene, built in 1861. Noble lived here until 1871 when he moved to Jesmond Dene House. The house later became refreshment rooms for park visitors. Deep Dene House was severely damaged by fire in Oct 2016.

Heaton High Pit. The 2nd edition OS mapping shows the pit covered by trees, so probably out of use by 1895. The tree-planted mound (known as The Spinney) is believed to have been planted to commemorate those killed in the Heaton Colliery disaster of 3rd May 1815. A plaque was later set up by the National Union of Mine-Workers Northumberland area in November 1966. However, tree planting was common on disused mine sites and it is argued that this site has no significance to the disaster at all. (See HER 4149 for more information about the disaster).
