dúnadan: Hallo everyone. Welcome to Dorset! It is a rather chilly afternoon and I am standing in the driveway of what I thought was Farmer Bill's house. Well, I know that it is because I have made this walk many times over the last couple of years. However, I have been greeted today by a rather unusual sight: A line of fortifications that seem to surround the farmhouse! The fortifications consists of logs with sharpened ends facing the house. In the corners there are two sentry towers. And... oh, there is a surprise, there are red squirrel sentries manning both!
farmer bill: Ahoy there, dúnadan!
dúnadan: Farmer Bill! He is calling me from his bedroom window! Hallo Farmer Bill!
farmer bill: If you see that dirty red squirrel, tell him if he wants to drink from my personal supply of cider, he has to pay like everyone else!
inq. cow: (coming from round the corner) Moooh! Hallo dúnadan!
dúnadan: Hallo, Gerrie. What is going on here?
inq. cow: Well, as you can see, the Little Red Baron has laid seige to Farmer Bill's house. He didn't have enough nuts to pay for the cider so he is hoping to starve Farmer Bill into submission. I feel rather guilty about it.
dúnadan: You do? Surely you never put Tecumseh up to this.
inq. cow: No, but earlier this week, and, I should add, in all innocence, I explained to him how armies used to lay siege to cities. He had asked me what a military investment was and I didn't know, so, I did what I usually do - find out - and reported back to him.
dúadan: I see! So, what do we have here, then?
inq. cow: These fortifications that are pointing towards Farmer Bill's house are called a circumvallation. That comes from the Latin circumvallare which means 'to surround with a siege work', or, more specifically, rampart. I am afraid to say that Tecumseh was less interested in that side of things.
dúnadan: I have to say that it is a very impressive construction. Why, the logs are over twenty feet high!
inq. cow: Tecumseh Squirrel and his Legion can be very resourceful! Now, here is a door. Let's go through it. Thankfully, Tecumseh hasn't had time to dig a ditch and I never told him about booby traps!
dúnadan: But what is the point of a door in a circumvallation!
inq. cow: Mrs Farmer Bill insisted on it so that she wasn't impeded when she wanted to go shopping!
dúnadan: Riiight. Well, we are walking through the door now and--- oh--- more fortifications.
circumvallationinq. cow: Yes, but look, these ones are pointing at us. You see, once I realised why Tecumseh Squirrel was so interested in learning about investments, I thought I better even things up by telling Farmer Bill what I had learnt about
contravallations.
dúnadan: These fortifications look just the same as the circumvallation except they are pointing outwards.
inq. cow: That's right! And for that reason they are called a 'contravallation'. Farmer Bill built it with Farmer Will and Gill. It helps defend the house but, of course, makes smuggling goods in more difficult. Here is the door...
dúnadan: So, we are now walking through the contravallation door. There is a gap of a few feet between the fortification and the house. The front door is open. I can hear speaking inside. Squeeks. It sounds like
(the front door is opened) squirrels!
inq. cow: Hullo! Two drunk farmers and a lot of drunk legionary squirrels!
little boots squirrel: Hello Gerrie!
Hic! Thish ish great cshider!
farmer will: Arhhh... these li'l chaps be great drinkers! We were talkin' 'bout pirates!
inq. cow: Dúnadan, when I joined you, Tecumseh was inspecting his circumvallation round the other side of the house. Moo! And Farmer Bill has barracaded himself into his bedroom...
(the kitchen door opens)
mrs farmer bill: Good morning Geraldine. Hallo Dúnadan.
dúnadan: Mrs Farmer Bill! It looks like the siege has been compramised by the infantry!
mrs farmer bill: Oh, yes. Well, let that dratted husband of mine and the warlike squirrel carry on their nonsense. I saw no need for everyone to have to get wet in the rain and cold in the night, so I said they could come in and have a free glass or two of
my cider!
dúnadan: What will happen when Farmer Bill and Tecumseh find out about this fraternising and your role in it?!
mrs farmer bill: They will have ME to deal with!
inq. cow: I foresee that this siege will end peaceably except for a clipped ear for any recalcitrant farmer and squirrel!
dúnadan: Indeed, shall we let these good folk and squirrels enjoy their drink and go outside?

Yee-hah!
dúnadan: We are now walking across the forecourt of the farmhouse, towards the barn from where I can hear music. What is going on?
inq. cow: Practice for tonight's hoedown!
dúnadan: I am straining to look through this rather high up window... I can see Ruddy Faced Helen the Farmhand. Is she doing a kind of Irish dance?
inq. cow: Silly. That fancy footwork is a hoedown.
dúnadan: Lot's of people are joining in, now!
inq, cow: The idea of a hoedown is that one person at a time takes centre stage to dance to a rapid piece of music - 2/4 time. Each person who follows tries to outdance the one who went before!
dúnadan: Don't tell me you taught Ruddy Faced Helen how to dance!
inq. cow: Of course not, but my mummy and daddy helped her out - although they do, of course, prefer the waltz. But mainly it was Bertie Pig. The hoedown is a private passion of the Pig family.
dúnadan: Yes, I see him now. Crikey, he is fast!
inq. cow: Do you know what the connection between the hoedown and rock and roll music is?
dúnadan: I can't imagine.
inq. cow: Both were started by black people but became popular with whites or, white people, later on! Isn't that interesting?!
dúnadan: What do you think it means?
inq. cow: Before answering that question, I should like to know about the socio-economic position of the people from where the music originated as it may be that it shows how culture can be influenced by the way people live.
dúnadan: Oooh, Helen just saw me and blew me a kiss! How nice. Right, we are almost out of time, Gerrie; what else has been making you inquisitive this week?

Geological Spiral Map
inq. cow: Epochs.
dúnadan: A particular period of time.
inq. cow: That's right. I have found, however, that epoch also has a geological and astronomical meaning. In regards the former, it is the division of a Period. In regards the latter, mooooh!, it is a particular phase in the development of the universe.
dúnadan: Can you give me an example of the geological meaning?
inq. cow: A pleasure! Today, we are living in the Holocene Epoch. Together with its predesessor, the Pleistocence Epoch, it forms the Quaternary Period. However, this may not be true for very much longer as some scientists have proposed that the rise of human beings constitutes a whole new epoch which they call the Anthropocene. In my field it is the Bovinopocene Period!
dúnadan: Ha ha! When did the Quaternary Period and Holocene Epochs start?
inq. cow: The Quaternary Period started 1.8 million years ago. That is quite some lives of cows and men back! The Holocene Epoch began only 11,500 years back. If you believe in the reality of the Anthropocene Epoch, it began 8,000 years ago with the advent of farming.
dúnadan: Gosh, all these numbers make me rather dizzy! I must sit down. Gerrie, it has been a pleasure as always speaking to you. I look forward to doing so again next week. Let's hope Tecumseh Squirrel's siege has ended peacefully by then!
