This is a shot of my foot in the mud and rice straw for the walls of the outbuilding. My feet are still stained with the color of the mud. The kids loved it, totally covered in mud. We mixed in enough water to make the mud the stiffness of bread dough.

splitting bamboo
This is a medium length pole. For the long ones we had to stand on top of the cab of the truck. Sometimes I wished I had a hardhat. Really trusted my partner
split bamboo
This photo is a shot of the pile of bamboo we split. It took most of the day to finish this lot. We had to haul some of the unsplit pieces we had cut out of the woods. Then we got to work on this around 10am. Finished around 4pm with a 1-hour lunch break. Once you get it down it's not so bad. This may or may not be enough for the who place.

Yet more rain, rotten for farmers
Yet more rain today. This has gone on for weeks. The rainy season, which is usually over by now, has dragged on into the summer that is usually sunny and hot. That is bad news for the farmers. Soy beans look like bean sprouts. They've been planted up north, but they aren't growing leaves.
On a more personal note, I need to put up some mud walls, but can't get out with all the rain. If we put them up in this weather they'd never dry and succomb to gravity.

How to Make a "Doma" or Tamped Earth Floor
If you are looking for a cheap way to make a hard floor in a foyer, in a shed, or barn, you may want to consider a tamped earth floor, or what is called "tataki" or "douma" in Japanese. Japanese buildings have all historically been tamped earth or wooden flooring. Some temples have earth floors over huge areas. Kitchens and storage building floors were often made of the material that is cool in the summer and warm in the winter. Recently home builders have been returning the material for its aesthetic appeal, as well as the cost. The floors last for decades with moderately heavy use, are easy to repair if they crack, and can be made smooth or textured and decorated. They are inexpensive, because the materials are available nearly anywhere, and you can do all of the work. Finally, in the end the floors return to their natural condition, dirt.
First you need to consider how large an area you want to cover. If your foyer is three meters square, and you want a floor that is fifteen centimeters thick, then you will have to have about one and a half cubic meters of compacted earth and lime in the end product. I recommend at least fifteen centimeters of thickness for a strong floor. The thing is though that once this is packed down, it is about 1/3 the height of the original materials untamped. That means that you will need to start with about three times the amount of sand and lime to compact for your floor with the desired dimensions. In other words, you will need a little more than three cubic meters of sand and a one cubic meter of lime for your three meter square floor.
After you have calculated the amount of the simple materials you will need, you need to prepare the area that will serve as the base for the floor. The beauty of an earth floor is that you can easily put it right on top of what ever base you have, dirt or concrete. (You cannot make this on top of a wooden floor, because it will crack as the wood floor bends during tamping and after it dries.) If you are making a floor on a dirt base, then you need to also decide whether you want to have hard edges. For example, if you are making it so that your door will close, you need to make a frame that will define the dimensions of the floor so your door will shut. You can do that easily with a stout board cut to fit the width and desired height. If you are making a ramp into a storage facility where you may be rolling in your wheeled lawn tools, then you will need to dig a shallow ditch of about 10 centimeters in depth and the same in width, with the ramp ending at the middle of the ditch.
Mixing the earth mixture is easy enough if you are covering a rather small area, but if you are dealing with a large shed or indoor area, a backhoe may be useful for mixing. Mix the lime and dry river sand together, mixing it thoroughly. Do this right before you are ready to spread and tamp it, because the lime will start to react to any moisture immediately. You can then start mixing in water. You will need enough that the mixture is something like beach sand after the waves have retreated, damp, but water does not drip out when held in your hand. Start shoveling it onto the area to cover and start tamping it.
A tamper can take many forms. In Japan, a wooden mallet was used to tamp smaller areas, and a pine log with four long handles, like shovel handles, for two people to lift and drop was used for larger areas. Pine was used for its weight, but also for its auspicious characteristics in Japanese folklore. For those who are less interested in details or who have an area that is too much to be dealt with by hand, a gas powered tamper will work just as well. As the mixture is compacted, more should be added on top and tamped until it reaches the desired depth. What ever you do, you will have to use all of the mixture that you made that day. It will harden as a pile as the lime reacts with the water, and will not keep.
Once you have beaten it to the desired area and depth, you should decide how you want to finish it. If you want a rough finish, that is fine. The tamping should have left marks, and those may work. You may want to add different designs by stamping in a rope to make letters. Some people work in marbles, pretty rocks, or ceramic tiles. Or you may want to make it smooth. If you want a smooth finish, you will need to rub it with a mason's float or trowel. First sprinkle the area you can work on immediately with a little water from a brush. Try a small area first and work your way up. Then with the float, give a small area a beating, and start to rub it with the float. It works best if you lift the leading edge just slightly as you smooth the area back and forth and round and round. The fine, wetter particles will come to the top, and the coarser particles will be worked into the center of the floor. The fine particles with eventually make a smooth surface. If there are areas that are lower than others, fill it it with some of the left over mixture, and beat it into place with the float or trowel.
The floor will dry from the inside out, meaning that the outside will feel wetter when you touch it that it really is on the inside, but you shouldn't let it dry too fast. You will have to avoid walking on it for some time. If you can give it a month, that would be best. If you live in a dry area, cover the floor with a grass mat and sprinkle it with water daily, just so keep it from drying so fast that it gets flaky or crumbly. If you live in a damp climate, like Japan, you will need to keep areas under a roof damp, and areas outside from washing away if there is, for example, a water drain coming off of the roof. After about a month you can use it normally.
As the years pass your tamped earth floor may develop cracks or wear out in spots. Just mix up a little soil, lime and water and pound it down, let it dry, and it will be good as new. If you sprinkle it with water from time to time, it will thank you, too, especially in dry indoor areas. Some people in some areas of the world put oil on their dirt floors. You may want to try that, too, but choose a non-petroleum oil with a smell that you can live with, especially if it will be in your living area.
Earthen floors have been used all over the world for millennia in all kinds of spaces. There are different details in the mixtures. Some places even mix ox blood into their mixture, but what they all have in common is that they use naturally occurring materials to make low maintenance floors that live and breath with you and the rest of your space. They are easy to make, even the kids can be involved in the process. (Keep them away from the lime!) They are beautiful and soulful to live with.

split bamboo and mix mud
Spent the day splitting bamboo and mixing mud for the mud walls. This is what you split bamboo with. You can probably guess how you use it.

Yet more rain.
More rain today, but had to go into work. Doesn't look like I'm going to get to the fields today. Tomorrow is a bamboo hauling day.

Heavy steady rain today
Heavy steady rain this morning. Won't go out to the fields today. Reading about saving tomato seeds in 2009 Farmer's Almanac. Think it may be prudent to start saving seeds. GM0's and "terminator genes" pose a threat to farmers like me and to plant life specifically.

Bamboo for Lattice Work in Mud Walls
Went out to cut bamboo for the walls that we are going to put in the outbuilding. We needed about 80 pieces from between 5 to 2 meters long. The bamboo we cut was on some property next to the home of the carpenter that his helping us build the building, and we got their permission to cut some. We tried to thin out the grove rather than cut everything in one patch. A person should be able to walk through a healthy bamboo stand with an open umbrella, and so with that in mind we cut the plants that were weak and too close to other healthy plants. We loaded it onto the truck, and drove it home, but it was quite a challenge. We took three loads back, and the leaf springs on the truck were flat.
I thought we would see more beasties. As it turned out we only saw one very big hornet. It was large enough that the beating of its wings blew dried out bamboo leaves as it passed close to the ground. Major insect.
Putting in A Beaten Earth Floor
We are in the process of building our out-building. Yesterday we put in our beaten earth floor. Here is how one is made the Japanese way. I guess that some places use ox blood in it. We did nothing that extraordinary.
We have an area about 50 square meters for which we wanted a floor to store our small tractor, other farm implements, and harvest through the winter. We have chosen to build as close to a traditional Japanese "kura" as our time and effort will allow. That means that instead of a tile roof with dirt underneath as an insulator, we are using galvanized metal with a foam insulator underneath. And instead of two layers of bamboo lattice in the walls, we will use one layer of lattice, making the walls about half as thick as the 40cm walls on the real deal. Yesterday we put in the beaten earth floor, it was quite a workout, but made considerably easier to do with experienced help and modern equipment.
We started by digging a 30cm wide and about 10cm deep ditch 30cm from the where the wall will start. The ditch will serve as a deep spot to keep the floor from slipping outward. There is also a ramp area in front of the door that will be kept relatively dry with the overhang on the front of the building, for which we dug a deeper ditch, about 30cm deep. We put a wooden frame around the building, just within the ditch. Then we started mixing earth and plaster. We used about three quarters alluvial sand to one quarter plaster with a small backhoe. We mixed a total of about 5 metric tons of earth, and started from the outside, shoveling in the sand and beating it down with hardwood mallets. They were short handled, and the business end was long and rounded. The entire mallet was about 50cm long, and the striking surface was about 30cm of that. We were working on building up about 15cm of beaten flooring, which required about three layers of earth. My guess is that loose earth compresses to about 1/3 of its original depth after beating. The outside floor required hand tamping, because it was laid around the beams of the building and inside the wooden frame. We used two gasoline powered tampers to compress the larger areas inside. The outside floor was nicely polished with a mason's trowel. One of the masons there to help us with the project kindly showed me the method for flattening and smoothing the surface. You must beat it to smooth out the bumps, and then sort of massage it with the trowel. This works the larger particles of sand in and brings the finer particles out, which smooths the floor.
We started working on the floor at around 8 in the morning and finished cleaning up and loading the equipment back on the trucks at around 6. Several of our friends came to help, and were happy to have had the experience. They are also working on developing their homesteads, and one family that came to help is in the process of building their own home with wood working studio and extra sleeping areas to come. I'm sure we will use our hard-earned experience with their projects, too.
It was hard work, and I am sore today from swinging those mallets, but we enjoyed the work and companionship, and now we have an earthen floor that will return to the earth, hopefully long after I have.

Chikens thriving
After a bit of a rough start, the chickens are thriving. First we had the incident with the older birds pecking the younger ones. We segregated the little ones into an old doghouse. They are well, and then one of the cats got through two layers of fence to grab one of the birds, injuring the chicken slightly. We brought both little ones in and warmed them up in a box with a light attached, and they are now happy and health. We have added another layer of protection to the sides, especially to keep the cats at bay. They are still interested, but can't get at the birds.
Now we are enjoying watching their growth. The little ones are getting their combs, and the older ones are getting wattles.

Students want to diet
My students, most of whom are first-year women, often comment that they need or want to diet in order to lose weight. I tell them to eat well. I don't just mean vast quantities, nor do I mean just expensive food. I mean eat good food that is good for you.
They are poor college students. All the better my dears. They don't have much money, so they need to spend it on good food. By that I mean chemical free, locally grown, high quality grains, vegetables, fruits, and meats if they're into them. Let me take meat for example. We are close to some of the highest quality beef grown in the country, Matsuzaka beef. It is beautiful and a meat eating experience like no other (if you're into meat), but it is expensive as blazes. No student could afford very much or very often. That would be the way to go. If they limit themselves to quality food, they will get less in grams, but more in satisfaction and health. Brown rice costs more than white (for reasons I can't explain), and chemical free is even more costly. Chemical free fruits and vegies are hard to find, but available at a higher cost. Everything will be less affordable when buying quality, but will satisfy and less is more when you want to lose weight in a healthy way.
If they eat this way, they can also be healthier than if they go for quantity rather than quality. When the buy for quantity, they get large loaves of white bread or white rice, lots of sugar and chemical additives, as well as more salt than they need. I hear students say that they had instant noodles for breakfast. They will crash long before lunch, they will binge eat large quantities of crap, and then then they will feel bad. Why bother? Have some brown rice in your rice cooker and a kettle the stove for a cup of quality instant soup (not the variety that they sell at supermarkets), and a cucumber, and there is a breakfast that will stay with you until lunch.
Since many of my students are women, so they want to eat sweets (a phenomenon that I was not aware of in the US) often in the form of cake. I tell them not to bother with hormone tainted cream cakes and white sugar when confections made with tofu cream and raw sugar are available at a few good cafes around the area. Granted, they won't be filling up on cake at the prices that quality sweets cost, but they will enjoy themselves and get something good for themselves in the process.
Don't know how many students take my advice, but if they are happy with themselves and healthier, we'll all benefit.

Sinus infections and allergies
An acquaintance is suffering from allergies and sinus infections, and I wanted to scream at them to change their eating habits. It happens to millions every year, and it used to happen to me. The weather changes; the flowers bloom and their heads swell to twice their normal dimensions. It would happen to me, too. To the extent that I am sure that sooner or later, I would have died either in the spring or the fall due, at least in part, to my conflicted breathing situation. The ironic part is that those are my favorite seasons, and I had come to dread them.
If you are suffering now from some kind of seasonal health issues, you don't have to. Of course see a physician for sinus infections. They are nasty. And then do this.

- Stop taking milk, yoghurt, ice-cream and other dairy products
- Switch from white bread to wholemeal and also begin to take brown rice, wholemeal noodles and other wholemeal products
- Eliminate red meat
- Eliminate white sugar and products containing sugar
- Eat lots more vegetables and fruits
- Eat less quantity overall all the time
- Eat better quality food

Ageing Japan's fertility rate up but population falls | Reuters
Japan's fertility rate up by 0.03 points, below the estimated 2.07 needed to keep the population at current levels. There were 51,300 more deaths than births.
Can't help but think this is a trend that the whole world should be reflecting, lowering human impact on an already over-burdened earth. Current economic dependencies on ever-increasing levels of consumption of cheap junk have to change to quality, long-lasting necessities.
There's lots of gloom and doom reportage here, like the phrase, "The low birth rate threatens to squeeze the economy by shrinking the labour force, which could weigh in on its GDP and leave fewer workers to support a growing number of pensioners." The paradigm here is that we need more and more workers churning out more and more crap to support old people. Why not fewer, more highly skilled workers turning out quality goods, and earning more to support pensioners. Either one is equally imaginable, but the former is just easier to accomplish. Business as usual laziness will accomplish that.

chicken coop door from outside
This is a shot of the front door that will lead to the fenced-in outdoor area where the chickens can move around outside. All of this will need to be weather proofed and painted nicely. My son has promised to do the art work.
chicken coop door from inside
This is a shot of the door from the inside. I may need to reinforce the top of the door later.
chicken coop side
I used this wire mesh on the sides to keep the birds cooler on hot summer nights. In the winter I'll cover those over with an opaque plastic sheet. You can also see the plastic roof that I put on the top.
