Field Survey, Bog House Farm, Mickleby
As the saying goes, practice makes perfect, and the results of our survey this month are very much improved. It does sometimes depend on actual field conditions, and as they seem to be favourable in this location, we will probably extend our survey area next month (weather permitting). If you would like to join us please email admin@jetcoast.co.uk or Tel 01947 844100
Flagstones were uncovered in this field during field drainage excavations, and on old maps, this section of the A174 is known as High Street. A pre C14th spindle whorl was also found close by.
The survey data map could reveal the presence of a range of buildings.

Group Members have recently undertaken surveys in a field between Ellerby and Runswick and at High Farm Hinderwell.
The 2006 Google image showed an interesting anomaly which gave us another opportunity to practice our field surveying skills, using the resistance meter.
This is an active geophysical technique which detects features in terms of resistance to the passage of an electric current. Most dry soils and rocks are insulators but, when moist, electric currents can flow through the movement of dissolved ions. Hence electrical resistivity surveying actually maps archaeology in terms of an associated variation in ground moisture.
To record the resistivity, a weak alternating current is injected into the ground through a pair of metal electrodes and the surface voltages are detected between a second pair. The presence of anomalous resistivity modifies the current flow (dotted lines) and the pattern of potential (solid lines). The instrument thus senses a maximum (or minimum) resistance which is centred over the feature.
Through good instrument designs, resistivity surveying is a rapid technique, although the need for soil contact and cables makes this a slower method than undertaking magnetometery surveys.
However, one benefit is that the user can control the sensing depth by changing the electrode spacing on the moving frame.
Measurements are taken at regular intervals on a grid. Both parallel and zig-zag traverse schemes can be used. Only about 0.5ha (1.2 acres) can be surveyed per day by one team, and the technique is physically demanding (as we all discovered!).
Measurements are collected by a data logger on the machine, downloaded onto a computer and processed to create a map of the readings.
We are new to mastering the art of field surveying, and the map results were not too clear. We will need to return to carry out a second survey next year.

Mills in Hinderwell Parish
Two group members recently attended a two day WEA Special Day School on Mills and their Development. The course covered topics such as the nature of grain and how man overcame the problem of extracting its nutritional components, the start of arable farming, the development of querns, harnessing water power and development of water mills, overcoming the problems associated with windmills, the role of the millwright, and the impact of the roller mill. The second day was spent visiting Bilsdale Mill where a complete restoration is planned, and the working Tocketts Mill at Guisborough.

| Dalehouse Water Mill Two millstones were powered by water carried across a wooden aqueduct (race) from Newton and Roxby becks. Used as a flour mill and for grinding meal. Ceased working in 1927. |

Foreshore Walk, Staithes
As part of this term's project on Oceans, Seton School pupils, accompanied by John Buglass, Kevin Cale and group members, enjoyed an informative walk along the foreshore at Staithes in search of relics relating to the fishing and ironstone industries, and as well as looking at marine life, fossils and the geology of the cliffs.
| Fossils from millions of years ago |
| Man-made feature - a Hully - used for storing live bait for the next day's fishing |
| Pupils stand in the post holes of the old Staithes Dock, to show it's length and direction |
| Exploring an old ironstone mining location |

Heritage Walk, Roxby - 5th July 2011
This was the fourth heritage walk round villages in the Mulgrave Ward. Previously the group has visited Mickleby, Hinderwell and Dalehouse. It is proving to be a very popular and well attended activity, which also encourages different people to get involved.
Nineteen people attended in Roxby, which included Clive Welford who has lived in the village all his life. He passed on his extensive historical knowledge and anecdotal stories about the village.
| Outside St.Nicholas' Church |
| All that remains of Roxby Manor |
| Turton Cottages - workshops and cottages built especially for the estate's blacksmith, carpenter and stonemason |
