These are questions I that I've often wondered about, since when I was growing up we learned in school about measuring the perimeter and the area of a piece of land, and were given figures for how large an acre was (4840 square yards, or 0.4 something hectares, whatever the heck those are, too.) But we were never taken outside and shown by measuring or even pacing off just how large an acre was in human terms.
Recently some homes on some old side roads went up for sale, and I would see signs that said "9 acre lot", "4.5 acre lot" or even "home plus 30 acres for sale". But without stopping and looking around, those are just numbers with no meaning.
Well, leave it to good old PBS to educate me once again.

I have been seeing the listings for the show Michael Wood's Story of England and finally was able to watch an episode last night.
It turns out that an acre of land is the amount of area that can be ploughed by a man with a team of two horses and a single bladed plough in one day. And that at one time all of the fields around a town were held in common, and the fields would be divided into long narrow strips of land of one acre each. And each family was given several strips of land to farm but not all in the same field, so that the best to the poorest farming land was equally divided amongst all. The strips were probably about 22 yards wide by 220 yards long, which is exactly one acre.
Later today I plan to pace off 22 yards across my street, and have a go at counting off 220 paces along the length of the street. Then I will know just how big an acre is, and get an idea of why it would take a full day to plough that much land.
I also learned a new word last night. In the show some property in the town was given to someone to live upon, comprising a house and just over 3 virgates of land. It turns out that a virgate is 30 acres. So the guy got about 100 acres of land along with his house, I figure.
I really should donate a few bucks to my local PBS station, even if I am a foreigner. I learn so much from their broadcasts, and this stuff sticks with me far longer than any of the crap I see on the commercial channels.
