Cornish Tin

Alternative Title: tinstone Cassiterite,

Alternative Title: tinstone


Cassiterite, also called tinstone, heavy, metallic, hard tin dioxide (SnO2) that is the major ore of tin. It is colourless when pure, but brown or black when iron impurities are present. Commercially important quantities occur in placer deposits, but cassiterite also occurs in granite and pegmatites. Early in the 15th century, the cassiterite veins in Saxony and Bohemia were mined for tin; peak production occurred there in the 17th century. In the 18th and much of the 19th centuries, the very large vein deposits of Cornwall were the major source of tin. Today most of the world’s cassiterite is mined in Malaysia, Indonesia, Bolivia, Nigeria, Myanmar (Burma), Thailand, and parts of China; other countries produce smaller amounts.

Fernworthy Forest, Dartmoor, Devon 


Location and ownership of woodlands 

This case study deals with the Forestry Commission’s Fernworthy Forest block on Dartmoor, some six miles south-west of Moretonhampstead. The total area of Fernworthy Forest is some 575ha (~1400 acres) of which ~150ha (~375 acres) has been designated for demonstration implementation of alternative silvicultural systems. The area of most relevance for ATC demonstration purposes is centred at SX 656835. 

These woodlands are owned and managed by the Forestry Commission, in consultation with South West Water who manage the neighbouring Fernworthy Reservoir. The vast majority of the site consists of twentieth century spruce plantations onto open upland moorland. Ferworthy Forest lies within the Dartmoor National Park and the South Dartmoor SSSI site, in a highly-sensitive landscape. 

Significance/ reasons for selection as case-study example 

This site has been selected as a case-study within this project for two main reasons:- 

1. It is one of the rather few examples where there is well-developed application of alternative silvicultural systems to perpetuation of upland Sitka spruce (adoption scenario 6). It can be compared with the Cwm Berwyn, Cefn Llwyd and Clocaenog cases. In an isolated plantation block within the sensitive Dartmoor landscape, adoption of ATC offers one approach to increasing public acceptance as a recreational resource, alongside timber production and watershed protection. 

2. The site is one of the Forestry Commission network of alternative silviculture demonstration sites and hence is fairly well recorded in terms of inventory and past silvicultural operations applied. Stands range from well-developed ATC with a complex structure, to young stands receiving a first ATC-directed thinning. This makes it a valuable ATC demonstration example for high yield Sitka spruce. 

Owner objectives for management (including adoption of ATC systems) 

The Forestry Commission in England manages its estates for a combination of economic timber production, conservation and recreational amenity objectives. The balance between these objective sets varies with the type of forest and its location. At Fernworthy Forest priorities have been economic timber production, catchment/ freshwater protection and recreational amenity. ATC is employed on a site specific basis by FC in support of management objectives. Alternative silvicultural systems are being adopted within this forest for demonstration purposes, and due to perception that landscape factors made perpetuation of forest cover a key priority and that existing spruce stands were regenerating. ATC should have significant economic benefits in terms of reduced restocking costs, environmental benefits by limiting the scope for siltation from clearfell operations and recreational amenity benefits in terms of maintaining a permanently forested landscape for the visitor experience.  
Biophysical characteristics of the site 

The areas of Fernworthy Forest of principle interest for ATC demonstration lie on the lower slopes surrounding the southern end of Fernworthy Reservoir and range in elevation from 350-400m asl, with north-easterly aspect. Other areas reach 500m asl. 

The climate of the site is fairly warm and wet [ESC AT5 ~1260 dd, MD ~75 mm, annual rainfall ~1840 mm] with a rather exposed wind regime for ATC [DAMS = 17]. The solid geology is of intrusive Dartmoor granite. Soils are primarily of the peaty podzolic type, in some cases with a substantial accumulation of peat. Hence these soils would typically have ESC SMR of Moist and ESC SNR of Very Poor. 

Terrain is moderate across most of the forest, with only 20% by area posing issues for conventional harvesting and forwarding machinery. The site has relatively good road access for silvicultural management and timber extraction over a network of internal tracks and rides, giving egress onto a nearby minor public road. However subsequent timber transport in the East Dartmoor locality is sensitive, with the busy visitor season to be avoided. There is public access thoughout the forest with basic visitor facilities. 

Stand history and current composition 

Fernworthy Forest is dominated by pure Sitka spruce crops established between 1920 and 1980 (with some younger stands being the second rotation on the site). These are high yielding crops with YC 14-24, average 16 for the forest as a whole but likely to be 18-24 for the more sheltered productive areas now under ATC transformation. The forest is notable for the development of large-diameter Sitka spruce with tree sizes in excess of 3m3 in the mature overstorey. There are also small areas of large-diameter Douglas fir, some western hemlock which regenerates strongly onto clearfelled sites and a limited amount of Japanese larch. Lower parts of the forest are already developing considerable structural diversity as a result of early advance regeneration. 

Silvicultural treatments applied to date and intended future silviculture 

A proportion of the older, well-thinned p1920’s and p1930’s spruce stands had “self converted” by advance regeneration prior to the formal ATC trial being established. The main silvicultural approach adopted since 2004 at Fernworthy Forest has been transformation thinning. While some of the older stands had received motor-manual intermediate first thinnings and brashing prior to establishment of the ATC demonstration project, younger stands had not. Thinning is now carried out using standard forestry harvester and forwarder equipment sets, although as the proportion of larger trees >0.7m3 increases, motor-manual initial felling and lower-stem crosscutting is required. Permanent racks are installed through the younger crops at 15m spacing, from which the intervening matrix can be intermediate first thinned by harvester reach without ground pressure within the growing area. Subsequent thinning strategy adopts a frame-tree selection/ crown thinning method by contrast to the standard intermediate or low thinning typically used in clearfell-restock forestry. Two different experimental stand treatments are applied depending on the desired final stand structure (a) simple two-storied shelterwood and (b) complex irregular. It has 
been found to be necessary to pre-mark frame trees prior to mechanised thinning as harvester cabs did not allow adequate visibility for feller-select crown thinning. Later thinning operations may require much greater dependence on motor-manual working. 

Considerable experience has been gained in avoiding damage to dense natural regeneration when thinning the over-storey in the older stands - this depends on effective directional felling when motor-manual techniques are used, coupled with carefell take-down control and lift-out to racks when mechanised harvester are used. Skidding has been considered inappropriate due to the greater risks of regeneration damage. Due to rapid growth rates, some natural regeneration in mature stands now requires respacing, which will be carried out with brush-cutters when 6ft in height. 

Evaluation of current silvicultural status in terms of ATC adoption/ regeneration 

Although formal conversion to alternative silvicultural systems only began at Fernworthy Forest in 2004, the profuse level of advance spruce regeneration and the rapid growth rates achieved in the forest mean that substantial areas have already reached developmental category 2 (progressive/ mature transformation) while others are at developmental category 3 (early-stage transformation). The most advanced areas have begun to develop some complexity and irregularity in their structure, while other areas are essentially uniform two-storeyed spruce shelterwoods. Continuation of ATC silvicultural transformation at Fernworthy Forest appears to be secure, as it is proving successful and forms an established part of the FC national ATC network. 

Commentary on inventory and monitoring protocols/ demonstration potential 

This site forms part of the Forestry Commission ATC demonstration site network and hence has an existing regime of enumeration for inventory and research purposes, using the protocols set out in FCIN45. The site therefore has considerable and ongoing ATC demonstration value and potential. The site is potentially suitable for both organised and self-guided learning visits, but, for the latter option, there would need to be a significant investment in interpretation materials (probably portable). 

Commentary on economic and operational implications of ATC adoption 

Economic and operational aspects of ATC adoption at Fernworthy Forest have been assessed and reported as a case-study within FR IPIN 13/06. The large size of some spruce trees has posed a challenge both in terms of the need for motor-manual felling and subsequent outsize marketing. Careful brash management to protect forwarding and extraction routes is required in case of thinning operations generating less brash. 

Other relevant field examples recorded within the project 

As an example of the application of ATC working to near-pure upland Sitka spruce, experiences at Fernworthy Forest can be compared with the Welsh examples at Cwm Berwyn and Cefn Llwyd Forests (Case Study 11), Clocaenog Forest (previous report) and the upland Scottish work at Kilmichael and Penninghame Forests (Case Study 12). Work at Fernworthy has been successful in large part, but for a number of reasons has not been as prominently reported as that at Clocaenog and Cefn Llwyd.

SS 90 SWCADBURY8/38Church of St Michael and All Angels5.4.66GVI

SS 90 SW CADBURY 8/38 Church of St Michael and All Angels 5.4.66 GV I Parish church. C12 font ; tower possibly C13 (q.v. Bickleigh): circa early C16 north aisle ; restoration of circa 1840 ; further restoration of 1857 by William White. Volcanic trap rubble with freestone (mostly Bathstone) dressings ; asbestos slate roofs ; C19 crested ridge tiles to nave and chancel. Plan of nave, chancel, west tower, 4-bay north arcade (1 bay to the chancel), south porch. The development of the church is not clear but it may have been a nave and chancel church with west tower in the C13, extended by a 4-bay aisle in the circa early C16. The porch is also early C16 origin. In 1843 the east and tower windows were described as "New" as were the altar and communion rails. The chancel roof may also date from the same phase. In 1857 William White rebuilt the south wall, replaced the north side windows and replaced the nave roof. The chancel has an east gable coped with Ham Hill and crowned with a cross, a 3-light circa 1840 Perpendicular east window with a hoodmould. The two south windows are both William White : one cinquefoil-headed light to the east and a 2-light Decorated style window to the west. Between them is a characteristically William White feature; a narrow priests' door inserted in a wide buttress with set-offs. The doorway is chamfered and stopped with a pointed segmental arch with a 2 plank door with strap hinges. To the east of the porch the nave has a William White window with 3 flush trefoil-headed lights, similar 2-light window to the west of the porch. The north aisle has coped north and south gables crowned with crosses and 3-light 1840 north and south windows, the east window with a hoodmould. The north side windows are 1857 by William White as is the C19 buttress with set- offs. The windows are asymmetrically-placed ; two 3-light windows with trefoil- headed lights and a similar 1-light window to the west. 3 stage unbuttresed, battlemented west tower without pinnacles or string courses. The tower is slightly battered with a large projecting rectangular north stair turret with slit windows. The tower has similarities to Bickleigh (q.v.) although the battlementing has been rebuilt. The west face has a volcanic trap shallow-moulded doorway with a pointed segmental arch, cushion stops and a C19 plank and cover strip door with strap hinges. 3-light circa 1840 Perpendicular west window with a hoodmould; 2-light belfry opening, the lintel a C19 replacement giving trefoil-headed lights, the original probably being cinquefoil-headed, the form of the belfry opening on the north face. The belfry openings on the east and south faces are granite with 2 segmental arched lights. The south face has a cinquefoil-headed opening at bellringers' stage. The porch has a coped gable, crowned with a cross and flush buttresses with set-offs; double-chamfered 2-centred doorway in volcanic trap, the inner order dying into the walls. The interior of the porch has timber-topped benches and a circa early C16 2- bay arch braced roof with moulded purlins and a collar purlin, the southernmost truss is a C19 replacement. Moulded 2-centred inner doorway in volcanic trap with cushion stops, door probably C20 but incorporating an earlier lock box. Interior Plastered walls; timber chancel arch formed by the abutment of the nave and chancel roofs ; plain tower arch with panelled soffit. Black and red C19 tiled dado. The 4-bay arcade has been painted but is probably Beerstone with shallow-moulded Tudor arches, piers with corner shafts and good, varied carved capitals. The aisle roof is probably early C16, a keeled unceiled waggon with the principal ribs moulded. The chancel roof, possibly circa 1840, is of similar design but with a carved wallplate and carved bosses. William White's 3-bay nave roof is arch braced with a collar purlin and collars between the common rafters which have diagonal boarding behind them. The easternmost truss, which forms the chancel arch, is carried on painted wooden posts on corbels. Numerous fittings of interest. The reredos is said to be 1890 (Church Guide, n.d.) but looks earlier : perhaps it is 1840 with later marble embellishments. It extends the width of the east end with gabled commandment boards to left and right and a central nodding ogee flanked by blind arcading. Polychromatic marble to the niches includes a corbel to support an altar cross. Stone credence table supported on a marble demi-angel. The floor tiling includes memorials to members of the Coleridge family and is probably 1857 ; timber Gothic communion rail of 1840. The altar, in situ in 1843 (Davidson), is made up of fine minutely-traceried panels, probably C16 and unlikely to be of English craftsmanship. The choir has some interesting stalls made up of a mixture of medieval and C19 bench ends; 1 bench end is especially interesting, shouldered with a crocketted head and carved with intersecting tracery very similar to the notable set at Atherington is North Devon. Unusual C17 lectern originally from Ottery St Mary (Cresswell) with strapwork decoration and a turned stem. Stone drum pulpit, possibly circa 1840, decorated with blind arches. Unusual, probably C12 volcanic trap font with a square bowl, scallopped underneath on a round stem with decoration on the plinth. The stem and plinth are C19. The font cover, circa 1840, clearly not designed for the present font, has an ogival profile and is carved with blind tracery. The benches in the nave are utilitarian C19 with rectangular ends. The east end of the south aisle is a family pew screened off by a low early C19 Gothic screen. A number of interest monuments. In the floor at the east end of the south aisle 3 ledger stones of the early C17 including a particularly fine one commemorating George Fursdon, died 1643, which includes armorial bearings in relief and a verse "Bee dumbe thou influence of officious verse/Fursdon esquier lyes veild within this herse/Twoold bee to rude an insolence to his shrine/too cloathe transcendent merit with a line"/. Early C19 grey and white marble wall monument on the north wall of the chancel to George Fursdon, died 1837, signed E. Gaffin, Regent St. London. Late C18 grey and white marble obelisk wall monument in the aisle to Charles Hale, died 1795, with a long inscription on a white marble sarcophagus. Also in the aisle a white marble wall monument to Elizabeth Lyon, died 1789, signed Kendall, Exon : an obelisk with a draped urn. Several other C19 wall monuments. Important late C15 stained glass in the east window of the north aisle, moved from the east window. A central figure of Christ showing his wounds was clearly originally part of a 7 sacraments design by the Doddiscombsleigh atelier of glass painters and is the largest single surviving figure from the workshop outside Exeter Cathedral. The flanking lights are probably by the Hardman company who provided 2 windows in the north aisle and 1 in the south aisle. Westernmost window in the south aisle by Clayton and Bell with a memorial date of 1877. Chancel windows by Beer of Exeter. A chest in the vestry (curtained off at the west end of the aisle) is said to be 1606 (Cresswell) and retains some painted decoration. A fine Church with notable glass and a good restoration by William White.

Castle Drogo near here is sometimes called the last castle built in England, and its position overlooking the steep wooded slopes of the River Teign is very suggestive of a medieval defensive site. This National Trust property only dates from the last century but it is impressive w and so too is the much smaller burial chamber at Spinster's Rock, a couple ol miles away, which is more than 3000 years older than Castle Drogo. This is an area where careful study of the Ordnance Survey map will reveal much ol interest, including Chagford Bridge, Gidleigh Castle and the standing stones and stone rows on Chagford Common.

St. Sexwulf.

44    SOME SAINTS OF STAFFORDSHIRE.
First and foremost, it was obligatory that many hours, both by day and night, should be spent in prayer. Again, every man trained to the priesthood was compelled to practice some kind of manual labour. This was a duty imposed on the priest while supervising his village flock, and on the bishops whilst governing a diocese more than one third the size of England. Some of the clergy, following the example of St. Paul, followed the more humble crafts; others, more cultivated, enriched their altars with chalices and patens wrought in precious metals, and added to their libraries manuscripts embellished with exquisitely finished illuminations. St. Dunstan, for example, worked in all the metals and was, moreover, a maker of church bells and organs. St. Wilfrid wrote the four Gospels in letters of gold on a purple ground, and presented them to the church at Ripon. In the days of Sexwulf, “ the dignity of labour ” was something more than a political catchword.
He spent much time in teaching and almsgiving, and more still, of course, in the administration of the diocese. Furthermore, he was an exalted member of the judiciary. To travellers of all nations and to the ecclesiastic with a grievance he was by law directed to consider himself “ a kinsman and a protector,” a phrase which exactly epitomises the revolution that Christianity had wrought in the national conscience. It was no empty phrase. When Rochester was destroyed by the Danes, the bishop of that place sought refuge with Sexwulf who at once found him a church at Hereford. He took, as I have said, an active part in the administration of the law, and diligently attended the chief courts of justice in his diocese, more especially the half-yearly shire-motes, where, by virtue of his office, he presided over the bench of ealdor-men. Here his superior education enabled him to instruct the ignorant, and his episcopal authority helped to control the passionate and prejudiced; more important still, it checked the besetting tendency of litigants to appeal to the pagan practices of their forefathers.

The British Medical Association



GP writing a prescription
who are the bma

Two leading health unions are calling on the home secretary to make the NHS exempt from a new charge which will be payable on overseas doctors and nurses.
The British Medical Association and the Royal College of Nursing say the Immigration Skills Charge, coming into effect in April, threatens NHS budgets.
It will mean the NHS must pay £1,000 per year for any worker coming to the UK from outside the European Union.
The government has said it is committed to building home-grown skills.
Nurses remain on an official list of occupations of which the UK has a shortage.

Recruitment drive

The unions have written to Home Secretary Amber Rudd, saying they are "deeply concerned" about the effects of the new charge.
They fear current staffing problems could be made worse when the Immigration Skills Charge begins.
In the letter, seen by the BBC, the unions say the government has suggested funds raised from the charge would be reinvested back into the UK health system. But the unions say they have been given "no guarantees".
The £1,000 charge for workers on Tier 2 visas, payable upfront, will add a significant amount to the bill for any hospital planning an overseas recruitment drive.
An example given on the BMA website says that if a hospital wanted to employ a doctor on a Tier 2 visa for five years, the hospital trust would need to pay £5,000 upfront when applying to UK Visas and Immigration for a certificate of sponsorship.


An NHS doctor

The unions say diverting funding away from frontline budgets "cannot be appropriate" and they want health and social care staff to be exempt from the charge.
The charge is aimed at cutting down on the number of businesses taking on migrant workers and incentivising the training of British people to fill those jobs.
However, the unions have said the NHS will continue to be reliant on doctors from the EU and overseas because of the length of time it takes to train a senior doctor.
They added that there were limited places at UK medical schools and on nursing degree courses to build the workforce that the government wants.
But the government insists the charge would help to encourage investment in training.
There is a reduced rate of £364 per worker for "small and charitable" sponsors.
It will also not apply to those in PhD-level jobs and international students switching from student visas to working visas.
The unions said it would be "unfair" to penalise employers for recruiting people on Tier 2 visas when checks are already in place to make sure jobs are offered to UK and EU nationals first.

ogham inscriptions,

Transcribed ogham inscriptions, which lack a letter for /p/, show Primitive Irish to be similar in morphology and inflections to Gaulish, Latin, Classical Greek and Sanskrit. Many of the characteristics of modern (and medieval) Irish, such as initial mutations, distinct "broad" and "slender" consonants and consonant clusters, are not yet apparent.
More than 300 ogham inscriptions are known in Ireland, including 121 in County Kerry and 81 in County Cork, and more than 75 found outside Ireland in western Britain and the Isle of Man, including more than 40 in Wales, where Irish colonists settled in the 3rd century, and about 30 in Scotland, although some of these are in Pictish. Many of the British inscriptions are bilingual in Irish and Latin, but none show any sign of the influence of Christianity or Christian epigraphic tradition, suggesting they date before 391, when Christianity became the official religion of the Roman Empire; only about a dozen of the Irish inscriptions show any such sign.
The majority of ogham inscriptions are memorials, consisting of the name of the deceased in the genitive case, followed by MAQI, MAQQI, "of the son" (Modern Irish mic), and the name of his father, or AVI, AVVI, "of the grandson", (Modern Irish uí) and the name of his grandfather: for example DALAGNI MAQI DALI, "[the stone] of Dalagnos son of Dalos". Sometimes the phrase MAQQI MUCOI, "of the son of the tribe", is used to show tribal affiliation. Some inscriptions appear to be border markers.[
Old Irish, written from the 6th century on, has most of the distinctive characteristics of Irish, including "broad" and "slender" consonants, initial mutations, loss of inflectional endings, and consonant clusters created by the loss of unstressed syllables, along with a number of significant vowel and consonant changes including the presence of the letter p.
As an example, a 5th-century king of Leinster, whose name is recorded in Old Irish king-lists and annals as Mac Caírthinn Uí Enechglaiss, is memorialised on an ogham stone near where he died. This gives the late Primitive Irish version of his name (in the genitive case), as MAQI CAIRATINI AVI INEQUAGLAS.[4] Similarly, the Corcu Duibne, a people of County Kerry known from Old Irish sources, are memorialised on a number of stones in their territory as DOVINIAS.[5] Old Irish filed, "poet (gen.)", appears in ogham as VELITAS.[6] In each case the development of Primitive to Old Irish shows the loss of unstressed syllables and certain consonant changes.

These changes, traced by historical linguistics, are not unusual in the development of languages but appear to have taken place unusually quickly in Irish. According to one theory given by John T. Koch,[4] these changes coincide with the conversion to Christianity and the introduction of Latin learning. All languages have various registers or levels of formality, the most formal of which, usually that of learning and religion, changes slowly while the most informal registers change much more quickly, but in most cases are prevented from developing into mutually unintelligible dialects by the existence of the more formal register. Koch argues that in pre-Christian Ireland the most formal register of the language would have been that used by the learned and religious class, the druids, for their ceremonies and teaching. After the conversion to Christianity the druids lost their influence, and formal Primitive Irish was replaced by the then Upper Class Irish of the nobility and Latin, the language of the new learned class, the Christian monks. The vernacular forms of Irish, i.e. the ordinary Irish spoken by the upper classes (formerly 'hidden' by the conservative influence of the formal register) came to the surface, giving the impression of having changed rapidly; a new written standard, Old Irish, established itself.
