I’ve just done the first charcoal burn of the year. Turned out not bad. Half the load was pre-sold and it was a good outturn 13 hefty 5 kg bags and 20 handy 2.5kg bags, or, technically, big and little bags.
One of the trickiest parts of making charcoal in a steel kiln is judging when to shut it all down by sealing out the air. Too early and the charcoal can be smoky when burning as all the tar hasn’t been burnt away and more brown ends are produced. Too late and you’ve burnt some of the charcoal away into the air. One way to judge the state of the burn is to look at the smoke.
This smoke is dirty-coloured. At the start of the burn the smoke is just about white as the wood’s moisture is driven off as steam. Then towards the end the smoke gets dirty as the built up tar burns and evaporates away. This is the sort of smoke you don’t want to inhale. Next comes the critical point. The smoke starts to clear a bit.
However, if it is left too long at this stage and the smoke turns blue, then you’re loosing money as the charcoal production starts to go up the chimneys! Notice ruined Bolton Priory in the background? What a place to work!
The final sign to heed is what is happening at the base of the air intakes.
The tar can be seen burning a pink colour here and it’s about time to shut down.
Theo and I delivered part of the bagged up out turn to Howgill Lodge caravan site and on the way we pass The Laund Oak. This is a veteran tree that used to mark the boundary between the forests of Barden and Knaresborough. You can see it’s a veteran from the hollow trunk, the massive girth and the dead limbs. There is still life in it though, its buds have not burst in this photo but there will be a modest display of oak leaves shortly.
Interesting word Laund; it means a clearing in a forest where deer can graze, and the legal definition in England is an area where deer were raised, principally for hunting by the king and his cronies, and occasionally poached by us peasants on pain of severe consequences at the hands of the verderers, who enforced the king’s law in the forests.
“…yet even from the wide tracts of forest, there was something more substantial to be gained than the pleasures of the chase. They were under the charge of bailiffs, who (in each bailiwick, as it was called) had their staff of foresters, verderers regarders, agistors, and woodwards, who collected and annually accounted for the profits of waifs, agistments, pannage … for the pasturage of hogs on the acorns, etc., … hollies, and perhaps other trees, for we have the word preserved in Anglo-Saxon, hirst, a wood), the croppiugs of which formed a principal article of winter fodder for cattle as well as sheep, and was valuable, as appears from an entry in Henry Younge’s, the forester of Barden’s book, a.d , 1437 : ‘ of husset sold to the amount of IV. iiis. viiid.’ (at least fifty pounds of our money), also of bark croppings, turbery (peat turf), and bee-stock. For in the old economy of the forest, wild bee-stocks were always an object of attention, and in France, as well as in England, officers called Bigres or Bigri (a byke was a bee’s nest in Chaitcer’s day), perhaps from Apigeri (bee-keepers) were appointed specially for pursuing the bees and securing their wax and honey. And it is to be remembered that those rugged districts, now stripped of their woods, are spoken of in the Compotus of Bolton as far from destitute of timber. The manor and chase of Barden comprised three thousand two hundred and fifty-two acres. The forest of Skipton. which comprised an area of six miles by four, or fifteen thousand three hundred and sixty acres, seems to have been enclosed from very early times with a pale, a practice indeed, introduced by the Norman Lord. Here the mast bearing and bacciferous trees, particularly the Arbutus, were planted ; and herein were nourished the stag, the wild boar, the fallow deer, the roe, and the oryx (or the wild bull), which, indeed, during the winter were fed with beans, even as the few remaining deer above Bolton are fed still. There was many a ‘ toft and croft ‘ also, as they were called (i.e., a homestead with a space of clear ground around it), where sheep browsed among the brushwood and glades. And so the forest furnished support for those who dwelt in it, either by fair means or foul.“ Edmund Bogg.

It’s a bit quieter in the forest today, and there seem to be about as many wooden deer produced as live ones. Here are two people, Jo and Andy, who came on a woodland course this week.
