Chalk-carts, like mice, and dead leaves, and most other matters in the universe are very curious and odd things in the eyes of wise and reasonable people.
The White Cliffs of Dover
I couldn’t find a definition of ‘chalk-carts’
anywhere although it’s obvious Kingsley was referring to the carts that carried chalk from the area where it was cut. From what I’ve read (here
, for example) it appears the carts were part of a horse-drawn industrial tramway,
something that was introduced at the beginning of the nineteenth century. This chapter was fascinating once I understood the gist of what Kingsley was getting at, which wasn’t obvious to me until after I’d done some digging around.
Come, let us find out something about the chalk before we talk about the caves. The chalk is here, and the caves are not; and “Learn from the thing that lies nearest you” is as good a rule as “Do the duty which lies nearest you.”
Chalk, limestone and marble are all forms of calcium carbonate. Chalk and limestone are formed in marine environments while marble is metamorphosed limestone.
This page explains the difference between limestone & marble.
Marl – a mixture of clay and calcium carbonate.
Many of these (chalk) pits are located near farms and settlements where one principal use of the chalk was for the production of lime which was used to ‘fertilise’ or ‘lighten’ heavier clay soils and also to improve drainage and make it more easy to cultivate.
The South Downs area of England is a series of chalk hills in the Hampshire, East Sussex, West Sussex counties. The chalk landscape acts like a giant sponge, and stores water. A huge underground reservoir provides fresh drinking water for over 1 million people living in the area.
– Kingsley didn’t use this phrase probably because it wasn’t in use until the late nineteenth century, but it refers to a limestone region where most or all of the drainage is by underground channels and where erosion has produced fissures, sinkholes, underground streams, and caverns. Some photos and more information here.
I’ve travelled across the Nullarbor Plain a few
times but it was only when I was reading though Madame How & Lady Why
that I discovered that it is the world’s largest limestone karst.

– one of the most famous chalk streams
of Hampshire in England which attracts anglers from all over the world.
Page 126 – invisible chalk in the water causes it to be ‘hard.’ A written narration from 10 year old Moozle:
“Chalk is many different things. Limestone is a harder form of chalk, and marble is chalk heated up. There is lots of chalk in England, the White cliffs of Dover are made of chalk, and lots of other things are made of chalk, not just in England, but in some other countries. The chalk runs out of caves made by the water in little streams, and thus deposits it in the rivers. If you drink water out of one of these rivers, it’ll taste kind of hard. That’s the chalk in the river that’s making it taste hard.”

Cave fomations (Speleothems) – some good photos here of Jenolan Caves in NSW.
How Stalactites & Stalagmites form – stalaCtites (form on the Ceiling) and stalaGmites (form on the Ground)
We\’ve done this experiment a few times with varying degrees of success: Make stalactites & stalagmites.

Another name for the Guacharo bird is the oilbird – Kingsley mentions that ‘The Indians kill and eat them for their fat.’

Wonderful gallery of photos of these birds here.

I think you need a medal for not only putting all of this together, but taking the time to post and share it with the rest of us. I can't give you the medal, but you have my unending gratitude. Between littles, a barfing epidemic in our house, and lack of sleep this just made my day!! Each of these posts have been invaluable to our Y4. Thank you.
Haha! I think I need a medal because I had to cull about half of what I originally had. There were so many interesting rabbit trails it got beyond me! I hope your family is getting back to good health. I used to plod along ok most of the time but sickness was one of those things that really knocked me off the rails.
Fascinating information Carol… I love geology and I can imagine that it must be difficult to cull so many interesting facts!M
I hated what little Geology I did in school so now I'm making up for my deficit & have discovered how interesting it really is.
This is such an amazing resource! Thank you for sharing it. We got behind with MHLW at the end of Y4 and missed doing this chapter, so we are going to start with it for Y5.
You're welcome. Good to know that it's useful 🙂
Just discovered this with my Year 5, and you revived MHLW for us! Thank you!!!
Great! Every now & again I check to see if the links still work. If you find one that doesn’t, let me know & I’ll fix it.
What an amazing resource! Thank you for all your hard work!
My pleasure. Thanks for taking the time to say so. 🙂
