Friday Flora and Fauna

Well bloggers.  Seeing as this is the first post in a new thread, I thought I’d start with the topic of communication.  Blogging , obviously, is a form of communication or display.  A way of sort of putting yourself out there and waiting to see if you’ll attract some or any attention.  Let’s leave the psychology of why humans do it aside and look at the natural world for a minute, where in most cases it’s a necessity.

Blogging in the natural world takes the form of the senses – colour, smell and sound.  In most cases it’s either one or the other and in some cases all three.  Of course when I say blogging, I’m referring to the passive expression of the animal or, in many cases, the plant, carried out in order to attract a mate or to outline a territory.

Many readers will be familiar with the antics of the bowerbirds of Australia and New Guinea where the male builds a bower, meticulously placing items in its display in order to attract a female.  Now here’s an interesting fact from the Wikipedia entry on bowerbirds…

In a striking example of what is known as the “transfer effect,” bowerbird species that build the most elaborate bowers are dull in color and show little variation between male and female, whereas in bowerbird species with less elaborate bowers the males have bright plumage. Presumably, evolution has “transferred” the reproductive benefits of bright male plumage (common among polygamous birds) to elaborate bowers, allowing males to display their fitness by means other than physical characteristics that would appear to attract predation.

The only reason I mention this is it may be applied in some way to the practice of assigning oneself an avatar on the web.  In short, if it’s not a photo of the person themselves, and even if it is, in some disguised form, just what does it say about that blogger?

Now this time of the year in Ireland is fairly quiet in terms of flora and fauna.  The trees have (all but a few hardies) lost their leaves and most mammals will have gone to ground or are preparing to go into hibernation.  But there a few around that still display the best in natural blogging, e.g. the Goldfinch, a common resident in Ireland but with plumage more like a tropical species.  In fact these birds were once in decline due to capture for the birdcage trade in the 19th century, until protection laws were passed in the 1930s, but more on that next week.

Eyre Square leather

AUTHOR: Billy Quinn

Introduction

Forty four worked leather pieces were retrieved from the Market House excavation (for more on the excavation see here) during the course of the Eyre Square Re-enhancement Project between the 3rd and the 18th of November 2004. Most of the fragments were retrieved from a rectangular sondage (approx 8m x 2m) excavated across the centre of the site representing successive metalled surfaces and dump deposits pre-dating the eighteenth century building. The majority of the pieces would appear to come from post-medieval contexts consisting largely of footwear fragments and off cuts.

Historical Context

The shoe styles found share similar characteristics with comparative urban excavations in Cork and Waterford and more locally from Barrack lane, Galway. The most common shoe type of the medieval period was the turnshoe, made as the name suggests by stitching a wet and inside out leather upper to a sole and then turning it rightside out so that the sewing is protected. The upper would then be wrapped around the foot and secured by either a strap, latched or using a thong. This simple template evolved through time for utilitarian purposes or simply as fashion dictated. Heels were initially made by sewing stiffeners inside the shoe to prevent wearing.

From the sixteenth century onwards heels developed into a series of separate “lifts” (“built heel”) stacked and pinned or sewed together. Similarly the upper changed from a simple wraparound piece to an overshoe consisting of a ‘vamp’ or toe covering, quarters covering the inner and outer sides of the foot, the tongue, a piece of leather to the front placed between two sides of a tied opening and the back strap. Another common shoe feature was a welt (sometimes called rand) or strip of leather stitched along the lasting margin between the upper and the sole to protect the seam and make the shoe watertight. Common shoes of the second half of the eighteenth century were the heavy brogue and the knee length boot. The native brogue (after the Irish bróga, meaning shoe) was a low heeled, heavy shoe of un-tanned leather with laces along the instep and no tongue with small perforations on the toe puff and quarters. This hardwearing footwear was practically designed for country men as a shoe that would drain water and dry quickly due to the lack of a tongue, and not get stuck in the mud because of their laces above the ankle. Knee length boots were an English introduction and were more expensive and associated with the landed gentry, given the restrictive laws for horse ownership during the penal law era.

Concerning leather as a raw material, cow hide was a generally used in the manufacture of most shoe soles, welts and binds – it being the strongest and most resilient of the available skins. For the uppers, calf, goat or sheep skin were the preferred choices for reasons of flexibility and comfort.

The Eyre Square Assemblage

Other than a few unidentified scraps, the bulk of the leather retrieved from the Eyre Square excavation was related to shoe making. A study of the fragments dated the majority of the finds to a period spanning the late sixteenth to eighteenth century. This determination was based on the complexity of the soles, the regularity of the stitching and the presence of stacked heels with lifts. This broad date stretching from the Nine Years War, through the Confederate Wars, and both the Cromwellian and Williamite campaigns up to the development of the Market House in the late eighteenth century is substantiated by both pottery and clay pipe fragments found in association.

Given this time frame, and despite a lack of uppers, It can be assumed that the majority of the shoes were of the welted type, dumped when beyond repair outside the city walls in a local mire, known as as’ the pool’. This pool is depicted on the 1651 Galway pictorial map and now lies under the road surface to the north of the existing traffic island surviving as a rich organic, peaty layer containing frequent sea shells and fragments of animal bone.

All the leather retrieved from this layer was reasonably well preserved due to the compactness and anaerobic nature of the peat. However, on recovery the pieces were fragmentary and prone to decay, making handling difficult. Following excavation the finds were bagged and kept wet and with some of the surrounding material before being sent for conservation. In the laboratory the entire assemblage was cleaned in water then impregnated with a 20% v/v aqueous PEG 400 solution before being freeze dried and further treated with industrial methelyated spirit.

Generally the shoe fragments displayed a degree of sophistication indicating professional fabrication. This contrasts with the earlier turnshoe types that a relative amateur could make. The welted shoe would have required a shoemakers specialist equipment including lasts, awls, shears, knives, stitch pricks, stitching sticks, templates and of course the raw material leather and cord.

From a study of leather fragments found at other urban excavations, particularly from Cork and borne out at Eyre Square, there is a proportionate disparity between finds of soles to uppers. As previously mentioned soles are generally harder wearing due to their laminated manufacture and preference for cow hide.

Most of the Eyre Square sole fragments indicate a degree of wear and tear, however there was little evidence of patching or repair. This suggests that the soles were dumped when worn out and that the shoe uppers were possibly re-used and re-cycled by local cobblers. That cobbling took place at a local level is attested too by the retrieved off cuts. None of the Eyre square shoe soles were found intact – all were broken at the waist or in two or more parts. Four of the better preserved soles, find no’s. 04E1561:27:57, 04E1561:105:209 and  04E1561:22:127:1 & 2 consisted of single thread pieces with a variety of stitching styles. Find No. 04E1561:27:57 was distinctive as having a toe stiffener glued under the sole (see image 3). Both find no’s 04E1561:22:127:1 & 2 were relatively small with very thin sole waists suggesting a ladies or child’s shoe. Specimen no. 04E1561:27:63 was a larger shoe that originally had three laminated soles. Another well preserved piece was 04E1561:112:11 – this complete waist and thread piece was finely stitched along its edge and would have been separately attached to a toe and seat piece (see image 1).

None of the upper fragments were intact enough to inform a discussion on the styles of the assemblage. There was no evidence for laceholes or decorative work. Of the larger pieces recovered one, 04E1561:131:12 a roughly squared piece, had two distinctive lengthwise creases in the shape of an instep. This piece may have been a sock liner reinforcing the sole and quarters and underpinning the vamp. Find no 04E1561:131:13:2 consisted of a double laminated possible quarter with holes along the top edge for a draw string. This is evident from the gathered appearance of the edge.

The Eyre square leather assemblage represents finds typical of the post medieval period, a period when shoemakers defined their profession as artisans rather than simply leather workers. Shoemakers from the 16th century onwards evolved their wears from manufacturing simple turnshoes to more sophisticated designs such as the welted shoe, brogue and knee length boot mirroring styles seen throughout Britain.

It is not possible to determine on the basis of the finds whether or not the shoes were of local manufacture or were imported from outside Galway County. That shoemaking thrived as a local industry is however in no doubt. Twenty six percent of a random list of 120 voting eligible professionals on the Galway Freemans roll of 1832 listed their occupation as either shoe or brogue makers.

Shoe puns welcome….. More small finds from Eyre Square coming soon…..

Friday Flora & Fauna

Announcing ‘Friday Flora and Fauna’…

From tomorrow, we’ll be posting a regular, topical flora and fauna column from Moore Group staff. We’ll follow the seasons and report on topical issues to do with the Irish environment and Irish Biodiversity. We’ll try and keep it regular to Fridays, but work pressures might affect the consistency occasionally!

Also later today, once we’re finishing editing it, there’ll be more from the specialist reports from the Eyre Square Enhancement Project excavations… mostly shoes today!

More Hot Rock technology

Following on from the innovative use of abandoned mine shafts in Holland to produce geo-thermally heated domestic hot water here’s some recent news of Google’s major investment in a potentially groundbreaking (pardon the deliberate, if poor, pun) method of using the natural heating power of the planet to provide massive amounts of hot water, on tap, so to speak.

Google, through it’s philanthropic arm, Google.org, has announced a multi-million dollar investment in a break-through energy technology called EGS (Enhanced Geothermal Systems). The traditional approach to large-scale geothermal relies on finding naturally occurring pockets of steam and hot water. The EGS system replicates these conditions by fracturing rock, circulating water through the system and using the resulting steam to drive a conventional turbine.

EGS could be the ‘killer app’ of the energy world. It has the potential to deliver vast quantities of power 24/7 and be captured nearly anywhere on the planet. And it would be a perfect complement to intermittent sources like solar and wind,

according to Dan Reicher, Director of Climate and Energy Initiatives for Google.org.

There is a very interesting Google Earth overlay here: http://www.google.org/egs/ showing the extent of the US Geo-thermal resource. And here, an MIT-led panel backs ‘Heat-Mining’ as a key source of energy for the US..

We’ve determined that heat mining can be economical in the short term, based on a global analysis of existing geothermal systems, an assessment of the total U.S. resource and continuing improvements in deep-drilling and reservoir stimulation technology,

said panel head Jefferson W. Tester, the H. P. Meissner Professor of Chemical Engineering at MIT.

Google’s ‘Renewable energy Cheaper than Coal’ initiative (RE<C), which is the driving force behind this investment in EGS, has some other interesting projects on the go, including plug-in vehicles and a 1.6 megawatt solar installation. More info here.

And more on the plug-in motors here, if you like that sort of thing:

The West of Ireland would be an ideal location for a geo-thermal array of this type because contrary to our wild, wet, cold and windy reputation, the west coast is actually one of the warmer parts of our island and it seems that the sunny South-east is a bit chilly under the surface!

Courtesy of the RIA website and a presentation given by Dr. Burkhard Sanner of the European GeoThermal Energy Council in Brussels to the ‘Where will Ireland get it’s Energy’ conference in Novenber 2007, we can see the heat flow densities throughout Ireland here.

It would also seem that we have the technology to make it happen, West of Ireland grown, as it happens, in Sligo based company, LotusWorks, and another West of Ireland based company involved in geothermal energy, this time in Iceland, Moore Group’s neighbours ABB.

Earlier this year a consultation process was initiated by Minister Eamonn Ryan on the options for geothermal energy generation so hopefully we will see some movement on this issue soon.
