The Ventura Effect
I've built many stone and brick Rumford fireplaces. They give off a lot more heat than most other masonry fireplace designs. Rumford’s genius was his intuitive understanding of fluid dynamics. By rounding the breast to “remove those local hindrances which forcibly prevent the smoke from following its natural tendency to go up the chimney…” and narrowing the channel to the throat, he essentially created a venturi, a nozzle, like an inverted carburetor, that shot the smoke and air much better up the chimney.
A Venturi, named after an Italian inventor, is a system for speeding flow of the fluid, by constricting it in a cone shape tube. In the restriction the fluid must increase its velocity reducing its pressure and producing a partial vacuum. As the fluid leave the constriction, its pressure increase back to the ambient or pipe level.
‘Ventura’ California where this year’s Stone Foundation Stone Symposium took place. This is the third time the symposium has been held in Ventura and like the others it was great smokin’ success.
Lectures, demonstrations, games, competitions, great food, plenty of ‘fluids’ and a impressive flow of stone aficionados. Well done. Tomas, Mimi and Paul & Laurie , Dougy B and all the stone tribe.

Walls and Sheep
Sunday, October 21, 2018
Yesterday was the first day of the two day pilot program offering a dry stone walling “experience” by the city of Kawartha Lakes. My students and I investigated some of the lesser seen walls on the Laidlaw and Mackenzie properties.
In the fall the we get a better view of the beautiful dry stone work, as there is less foliage covering the walls. This wall is at least 150 years old and runs for about a thousand feet towards the lake. There is a similar one on the other side of the lane. The trees have all grown up since the walls were built. They will eventually destroy the walls, but such is life. Life and living things eventually prevail.

Stones are at their best when they are ‘mobilized’. They can stay well-connected, yet need not be tightly regimented, that is, not forced to be locked together in an order that makes the whole thing totally immovable and uninteresting.
Fabrications boasting of manufactured adherents that last a lifetime all too often are lifeless and ugly.
By contrast, mobilized stones (not bolted or glued or stuck together with cement but placed skillfully and correctly) by themselves, are ones arranged so as to mesh together beautifully.
The stones will remain that way a long time, nestled in a state of connectivity. They all keep within their orbit, in constant structural conformity. They yield because they are placed together employing only the basic restraints of gravity and friction, thus allowing for a constant flow of invisible interactions. The wall is a kinetic work , never losing balance or uniformity.
The whole thing is stone mobile, dancing in an almost motionless embrace. A dry laid installation is not a ‘stalled’ one, not brittle or frozen. That which is made up of unfettered stones becomes a thing of beauty - a fluid sculpture held in place by the subtle forces of nature. Stones held together this way will always be something to behold.
The whole thing becomes a ‘moving’ experience.

A hard decision
A rock 'is' like a hard decision, or rather,
a hard decision is 'like' a rock.
They are both hard.
The only difference is the rock is not complicated.
The only difference is the rock is not complicated.
It is the simplification of hardness.
The rock takes it from an abstract concept to the purely physical embodiment of hardness, as a solvable attribute. After all, a rock even though hard, is in the end solvable . Ultimately when placed or shaped or broken or ground up or acted upon by various chemical forces becomes a solution, (in some cases a kind of mineral solvent, if you will)
The problem is how to assimilate the rock-likeness analogy to the 'hard' decision.
The assumption is that there is a better answer, a truer answer, a more noble answer, one that you can live with at least. In the case of needing to make a hard decision there is the idea that there exists an opportunity not to get 'it' wrong, or rather, there is a correct choice that will set things up better, for not just you, but for the general populace .
Setting a rock in the right place, even though it's a big one and a heavy rock and obviously a hard one, is good practice for making hard decisions.
It will likely be long lasting. It will likely be obvious that it looks good or bad after you've done it. In most respects the risk will somehow be have been worth taking.
A hard decision maybe involves a heck of a lot of fact finding and complicated logistics and perhaps even moral considerations.
But here again it still has to do with hardness and determining the problem’s/rock’s weight.
In the end all rocks ‘wait’ to be moved. Their weight and hardness is a given. If we choose not to make the move, it is not a hard decision. If we choose to move it incorrectly, we will likely find out. (and then decide to fix it ) But if we don't choose, we will never know, and to avoid choices may be even harder in the end than handling rocks all day OR making hard decisions.

Ruins from an imaginary past.
There are many castles in your imagination.
If you look among old stone ruins you may discover something very hopeful and yes, strangely enchanting.
You will always find new inspiration.
When you explore ‘new’ ruins you may even start to remember places you’ve never been before.
There are many castles in your imagination. Start building them.

Staying warm in the bleachers
We walled ourselves by the fire at the end of the second day of last weekend’s workshop at Sara’s Garden. Our team built a dry stone ‘bleachers feature’. Large slabs supported by courses of stone provided seating that rose up and around a large lava stone pot. Rather than a fire pit we made a kind of ‘mini flame stadium’. Glow team go.Glow team go !

Last weekend I revisited Sara’s Garden and took this photo of the ‘Irish Ditch’ wall that we built several years ago at the dry stone workshop I was asked to teach. The sedum has grown in beautifully. The herringstones appear to have almost melted into each other and have somehow taken on more purplish tones.
Maybe trying to come up with a variation of the wall shaping the stones to look like actual letters might be introducing a bit of a read herring.

Why on earth?
At times like this, maybe sitting a rock bench, or surrounded by some natural rock formation, or maybe just standing in a circle of carefully fitted stones, I find myself wondering what on earth are we doing here.
I ask myself ‘Why on earth are we here? How on earth, l wonder, are we supposed to figure anything out? And where on earth are we supposed find the answers?’
Perhaps the one important clue comes contained in the actual formation of these questions. It is on this ‘earth’, where we actually all are, that we come asking. All of us!
As a mysterious collection of dust particles ‘it’ (the earth) is ‘what’ we all are ‘of’ too. And in the computer complex world of silicon chips, made from quartz found in the sand (found everywhere on earth) it seems we are discovering new amazing ways also to probe the frontiers of how and perhaps why we are the way we are.
The earth is the answer. Rocks of earth - made of a myriad of earth’s minerals - stones of all earthly sizes and shapes provide the bedrock foundation of knowing.
The wonderful arrangements our earth takes, in the form of rocks and mountains and canyons, cliffs, islands, the endless shorelines of sand and pebbles , all these earthy things may seem abstract and incomprehensible, but the intuitive ‘knowing’ that comes to all of us with merely spending time in their presence, is undeniable.

Shades of the Lake District
The Amherst Island Festival wall, built last weekend in Canada, is modelled after walls John Scott and I saw in the Lake District on a trip back in 2011. Rows of round 'beck stones' (river rock) are laid in double or triple courses with rows of flatter slate bringing the wall to flat at each new interval of height.
At Amherst, local surface granite fieldstone and flattish limestone was used. The final look is both not only tidy and stunning to look at it is also very structural.
