Elm tree and the history of land development in Obihiro. ハルニレの木と帯広開拓の歴史
A 200 years old elm tree near the Inada water pump station, and a big elm tree with many combined tree trunks near Kikanko river. Monuments of pioneers from Sakauchi village, Gifu prefecture, settled in Kawanishi village, and an another monument in the campus of OUAVM, praising the pioneer land owner who offered his land to Obihiro Agricultural High School and OUAVM. How are they related each other?
When the elm tree near the Inada water pump station started to grow, no people from the main island of Japan lived in this place. Later, people settled in this place cut the trees around this tree. Therefore, this tree could spread its branches and twigs widely from its very thick trunk with around 3 m diameter.
On the other hand, when I saw the elm tree near the Kikanko river, I wondered why this tree has so many combined trunks. A curator of the Obihiro Centennial Museum, Mr. Ikeda, taught me that this tree should have been cut once. After being cut, many new stems grew again from the stump and grew big again. Many trunks from the stump were combined together and formed the present tree.
When this elm tree was cut once? It should have been the age when people settled in Kawanishi village around 120 years ago. In 1897 (Meiji 29), people from the Sakauchi village in Gifu prefecture, central Japan, settled in this place. One or two years ahead, Mr. Nakamura from Fukui prefecture, central Japan, also settled in this place, and started clearing the forest and cultivating the land. The land cultivated by the family of Mr. Nakamura was later-on donated to Obihiro Agricultural High School and the Obihiro University of Agriculture and Veterinary Medicine.

Views from Tokachi Hills Garden and Morinoyama. 十勝ヒルズと帯広の森「もりの山」からの眺め。
My friend during my student age visited me after 37 years absence since the occasion of my wedding ceremony with my wife. I brought him to some places in Obihiro where we can enjoy the nice view.
Outing to Fukuhara-Sansou lodge with red maple leaves and Mt. Haku-un-san. 紅葉の福原山荘と白雲山の散策。
On October 5, I went out to see red maple leaves in the garden of Fukuhara-Sanso lodge in the mountain foot area of Shikaribetsu. It is a private garden, and open to public only in this season until October 21.
After visiting the garden of Fukuhara-Sanso lodge, I proceeded to Shikaribetsu lake and Mt. Haku-un-san. As it was already after 3 o'clock when I arrived at the starting point of Mt. Haku-un-san, I could not climb to the summit of the mountain. I walked around 2 hours in the mountain and came back. It was a very comfortable walk, because the weather was fine and not hot.
Autumn colors in the Green Park of Obihiro. 帯広グリーンパークの紅葉。
I visited the green park of Obihiro by bicycle to enjoy the colored leaves. Compared with last year, the autumn color is delayed and not so brilliant maybe damaged by the strong typhoons which attacked Japan repeatedly.
Red maple leaves and the lawn of the green park.
Yellow and red leaves of katsura and maple trees.
Maple trees and forest in the park.
Art stone carvings along the walking path and mushrooms found along the way.
Today, we had a very fine day here in Tokachi. People in Tokachi, Hokkaido, are proud of such fine day calling "Tokachi-bare". I went to the river-side forest of Kikanko river to pick mushrooms, cleaned my crops in the garden, then visited three view spots in the suburbs of Obihiro city, Iwanai Senkyou (hidden valley in Iwanai), Shichiku garden, and Manabe garden.

Scenes of roadside trees and park trees in autumn color are shown. I also walked along the western bank of Satsunai river. I was interested to see the seed bags of Metaplexis japonica, which contain wooly hair and seeds inside. When I visited here last year, all seed bags were already hatched and the wooly hair and seeds have blown off by winds. This time, the seed bags were still colored green. I also found the Japanese native wild hop.

This afternoon (October 19), I climbed a small mountain named “Mt. Kunimi-yama” to the north of Obihiro city. It belongs to national forest and managed as a forest for nature observation and education by the national forest management bureau in the west Tokachi area. I climbed this mountain 27 years ago with my family (my wife and three kids) joining the bus tour organized by the forest management bureau. Since then I have not climbed this mountain. It was very fine today, and I could enjoy an exercise in a refreshing air and a beautiful forest with yellow and red colored leaves. It is only 30 minutes drive from my house, and the climbing is easy as the height of the mountain is only 128 m and the climbing routes are managed in very good condition.

上：A view of Shirakawa-gou, from the observatory, where I visited in the excursion of IHSS18 meeting on 14 September. Shirakawa-gou in Gifu prefecture is famous for the traditional old thatched houses of the villagers. Each house is a triangle shaped, three storied very high building. Villagers raised silk worm in the higher stories, and produced the ingredient for gun powder by fermenting the soil in the basement. Shirakawa-gou had been an isolated village deep in high mountains. It had been one of the hidden villages in Japan. These years, however, millions of peaple visit there thanks to the construction of a highway, though only a thousands of people are living there.

This statue of large shovel stands near the entrance of the Kroeller Mueller open air museum in the Netherlands. Construction of this statue was a hard work. After one year of the settlement, this statue fell down. The artist improved the underground structure of this statue and painted it blue from silver, then settled it again. What does this large shovel mean? Maybe it is because Van Gogh drew often shovels in his pictures. This museum owns many works of Van Gogh.

Manabe Garden is at the peak of autumn color. 紅葉のピークを迎えた真鍋庭園。
10月20日の午後は、紅葉のピークを迎えた真鍋庭園に行きました。運動不足対策もかねて、往復ともに歩いて行きました。行きは機関庫川沿いの道を、帰りには札内川の堤防上の道を通って帰ってきました。
In the afternoon of October 20, I visited the Manabe garden, where the autumn colored leaves are at their maximum peak. I walked the path along the Kikanko river to the garden and came home through the path on the bank of Satsunai river.
The way to the Manabe garden. Ripe red seeds of Japanese spindle tree, swamp ash trees along Kikanko river (two photos) and three trees (maple, elm, and swamp ash) near the athletic ground of Obihiro Kita high school.

今日は帯広市図書館の帰りにグリーンパークの紅葉を見てきました。帯広市の紅葉の名所のひとつだけあってさすがに見事でした。グリーンパークの長辺は400m以上あるので、駐車場から紅葉並木の端まで往復すると1 kmくらい歩いたことになります。
この公園には400 m の長さを誇る木のベンチがあり、これが作られた1981年時点では世界一長いベンチでした。その記録は1987年に破られましたが、それでも日本で３番目に長いベンチだそうです。
Today, I visited the Green Park of Obihiro on the way home from the Obihiro library. Here also, the red color of the maple tree is at its maximum now. Green Park is a very wide park, and the length from the end to end is larger than 400 m. Therefore, I walked 1 km for the round way from the parking place to the end of the maple alley.
There is a 400 m long wooden bench in this park, and it was the longest bench in the world when it was constructed in 1981. Now it is the third longest bench in Japan.
The census of Hokkaido squirrels in the forest of Obihiro. 帯広の森でエゾリス生息数の調査。
10月27日は6:30 から帯広の森でのエゾリス生息数の調査に１年ぶりに参加しました。１年前も小雨でしたが、今朝も雨でした。雨でもエゾリスは現れるとのことで、調査は続けているそうです。藪こぎをしながらの調査なので大変でした。約2kmを２時間くらいかけて歩き、エゾリスは６匹みつかりました。
After a one year blank since October 28 of last year, I joined the census activity of Hokkaido squirrels in the forest of Obihiro. It was a rainy day, but squirrels appeared. We could find 6 squirrels along the around 2 km walk in the bush and forest.
Next day, I visited Obihiro river near the area where I conducted the census of squirrels. I used to come here for fishing when my kids were the age of elementary school.

Final stage of colored maples in the Manabe Garden. 終盤を迎えた真鍋庭園の紅葉。
10月28日の午後は真鍋庭園に行きました。紅葉もそろそろ終盤かと思いますが、朝晩の冷え込みのせいか紅葉は一層鮮やかになっていました。
In the afternoon of October 28, I visited the Manabe garden. The autumn colored leaves are approaching their final stage. However, they looked very brilliant due to the cold temperature in the morning.
Big elm tree near the Manabe garden. Leaves have turned yellow and fallen. Trunks and branches could be seen through the leaves. Fields along the Satsunai river have been plowed, preparing for the crops in next year.

I prepared a soil monolith using the soil samples collected from the soil profile in the Junior Course field in May - June, 2018. The change in color and the degree of weathering in different soil layers can be represented easily.
Visit to Japanese crane sanctuary in Tsurui village and the Kushiro wetland visitor center at Onnenai, Kushiro. 鶴居ー伊藤丹頂サンクチュアリーと釧路湿原温根内ビジターセンターの訪問
11月2日午後に釧路市で所用があり、前日から鶴居村のホテルに泊まり、午前中は鶴居・伊藤丹頂サンクチュアリーと釧路湿原温根内ビジターセンターを訪問しました。
As I had some appointment in the afternoon of November 2, I stayed in a hotel in Tsurui village on November 1. In the morning of November 2, I visited the Japanese crane sanctuary in Tsurui village and the Kushiro wetland visitor center at Onnenai, Kushiro.
Japanese crane sanctuary in Tsurui village. When I arrived here, I could find three cranes, male, female and their child bird. They were eating the dent corn fed by the staff of the center. After a while, another family flied into the same site. The newly arrived family cried loudly, then the family which was there from the beginning left the site. The staff of the center told me that the male bird which came later is an older and stronger bird. A crowd of Japanese crane also flied over the site, but they did not land on the site, noticing the family of strong male bird was already there.
Kushiro wetland visitor center at Onnenai, Kushiro. I walked along the wooden path in the wetland, in total 3 km long.
There had been here a narrow type rail road connecting Shin-Fuji in Kushiro city and Naka-Setsuri in Tsurui village since 1928 to 1968.
Sunrise seen from the cape Tohfutsu in Kiritappu. 霧多布湯沸岬から見た日の出。
11月2日午後の釧路市での所用のあとは霧多布に移動し、霧多布岬にある「えとぴりか村」という民宿に泊まりました。翌朝は早く起きて湯沸岬からの日の出を見に行き、朝食後は湯沸下海岸に行き、拾い昆布漁の漁師さんの仕事を見ました。チェックアウト後はラッコの家族が見られるかもしれないとのことで再び湯沸岬に行きましたが、あいにくラッコは見つかりませんでした。
After my appointment in Kushiro, I moved to Kiritappu to stay in a private B and B lodging "Etopirika-mura". On November 3, I woke up early and went to
the cape Tohfutsu to see the sunrise before breakfast. After the breakfast, I walked down to the beach to see the fishermen harvesting the sea tangle which were washed ashore. After checking out the lodging, I visited the cape Tohfutsu again, as I might be able to see a family of sea otter in the sea, but I could not find them.

Views of mountains in Tokachi from Mt. Kunimiyma and "Morinoyama" in the forest of Obihiro. 国見山と帯広の森"もりの山"からの十勝の山の眺め。
帯広へ帰った翌日、国見山と「もりの山」に散策に行きました。この日も快晴で十勝の山々がよく見えました。山々の頂きは既に雪で白くなっていました。
実は２週間前に行った時、入口のゲート付近に「11月4日に国見山の自然観察会(詳しい名称は忘れました)をやります。定員は20名です。」というポスターが掲示してあったので、飛び入りでも入れてもらえるかもしれないと思い行ってみました。集合時刻15分前の８時15分に駐車場に着いたらまだ誰もおらず、３０分になっても誰も来ません。しばらくして年配の方が来られたので聞いてみたら、たしかにそのお知らせの紙は以前貼ってありましたねとのことで、私の勘違いではなかったようです。
そこで、その方と一緒に登ることにしました。もともと観察会には運が良ければ入れてもらおうくらいの気持ちでしたので、それで構いませんでした。初めて会った私より７歳年上の方といろいろお話ししながら登れて良かったです。 今回は前回には通らなかった国見山の外周を１周するコースを歩きました。外国の森コースを登り、展望台コースを降りてきました。外国の森コースは道がぬかるんでいて歩きにくかったです。これは、同行の方のお話によると、登山道を整備するために重機で道を削ったためだそうです。人手不足と予算不足で安易な整備をしたための失敗のようです。
On the next day after I returned from my trip, I visited Mt. Kunimiyama in the suburbs of Obihiro and "Morinoyama" in the forest of Obihiro. It was also very fine and I could enjoy the nice view of the mountains in Tokachi. Summits of the mountains were already white with snow.

Scenes of late autumn along my walking path. 散歩道周辺の晩秋の景色。
11月9日、天気がだんだん悪くなっていくようなので、朝のうちに散歩に出かけました。もみじはほとんどの木が葉を落としてしまいましたが、まだ街路樹や公園の木の中には赤い葉の残っているものもありました。森の中の道も落ち葉が積もっていました。
On November 9, just before it rained, I made my routine walk along the stream of Kikanko river and in the forest of agricultural high school. Though most of maple trees have fallen down their leaves, some trees still remained their red leaves. The path in the forest was also covered with oak leaves.

Triangulation points and survey level points around my house. わが家周辺の三角点と水準点。
10年ほど前にもやったことがありますが、再び三角点・水準点探しをやってみました。緑ヶ丘公園に行ったのも三角点探しの一環です。三角点は地形図上に三角の記号で、水準点は四角の記号で表してあります。水準点の方がたくさんあります。あらかじめ地形図で確認しておいたのですが、三角点は予定のものが全てみつかりましたが、水準点はみつかりませんでした。宅地化などで失われたものもあるのか、私の探しかたが不足しているのかもしれません。いずれも木立の中とか、あまり目につかないところにひっそりと佇んでいます。

First snow and walk along Urikai river. 初雪と売買川沿いの散歩。
帯広はじめ全道で11月22日には雪が降りました。一昨日も少し降りましたが、今日は雪らしい雪でした。去年と比べるとほぼ１ヶ月遅れで、別に早く雪が降ってほしかったわけではありませんが、いつ降るのだろうと気になっていました。最近はいろいろと災害でも気象でも例外的なことが続きますが、この遅雪も関係があるのでしょうか？雪が降らない間に私は三角点探し、散歩、庭園散策などを楽しませてもらいましたが、雪が降ったあとも務めて散歩などの運動は続けたいと思います。
機関庫川と売買川沿いの散歩。朝晩白鳥の鳴き声が聞こえるので、売買川にももう白鳥が来ているかもしれないと思い、散歩がてら行ってみましたが、まだいませんでした。しかし、散歩の帰り道で、鳴きながら飛んでいく白鳥の群れを見ることができました。
On November 22, snow fell allover in Hokkaido including Obihiro. Though it also snowed the day before yesterday, it snowed more. The first snow was very late this year, and almost one month later compared with last year in Obihiro. Though I was not waiting for the snow, I felt strange that it did not snow until such late date. Recently, irregular weather and natural calamities are continuously occurring. The late first snow may also have something to do with such tendency. I could enjoy going out looking for the triangulation points, walking in parks and forests before it snowed. However, even after becoming the snow season, I would like to continue my walking.
In my place, we can hear the voice of swans mornings and evenings these days. I thought that they are already in Urikai river as I saw them there last year. This afternoon, I walked to Urikai river and walked along the river bank. Swans were not there yet, but I could see swans flying in the sky crying to each other on my way home.
Harvest of white radish and carrot from my garden, and the walk in the afternoon. 大根・人参の収穫と午後の散歩。
いよいよしばれてきたので、庭に残してあった大根と人参を収穫しました。もっと小さいかと思っていましたが、まあまあの大きさに育っていました。午後には散歩に出かけました。いつも通る機関庫川沿いと農業高校の学校林の端の道でした。森の中は風も弱められ、足元もすべらず歩きやすいです。
As it has become very cold in the morning, I harvested the white radish and carrot in my garden. In the afternoon, I made a routine walk.
Walk along the western bank of Satsunai river to Manabe garden. 札内川西側堤防を通って、真鍋庭園まで散歩。
今日（11月24日）は札内川の堤防を通って真鍋庭園まで行ってきました。堤防ではガガイモの実がほとんど全てはじけて綿毛を飛ばしていました。真鍋庭園では一昨日の雪が残っていて雪景色を楽しむことができました。
In the afternoon of November 24, I went to Manabe garden passing through the western bank of Satsunai river. Seed bags of Metaplexis japonica have already opened and wooly haired seeds have appeared. Snow remained in Manabe garden, and I could enjoy the snowy scene of the garden.

札内川と十勝幌尻岳。今日（11月26日）は非常勤講師とミニバレーと散歩（サイクリング）をしたらもう日が暮れてしまいました。三角点探しも兼ねていたのですが、見つからず、家に帰って地図を確認したら水準点でした。水準点には黄色の標識はありません。
View of Satsunai river and Mt. Tokachi-Poroshiri in the evening. One day is very short these days. This morning, I had a lecture as a part-time lecturer in the college, at lunch break enjoyed playing mini-volley ball, and after coming back home, went out again to ride a bicycle along the eastern bank of Satsunai river. I intended also to find another triangulation point, but I could not find it. It was my mistake, the point I expected was not a triangulation point but a bench mark, which does not have a yellow indicator.

Searching another triangulation points, and finding the flock of swans in the field. 三角点探しと畑の白鳥の群れ。
11月28日は散歩のコースを変えてみたところ、畑で休んでいる白鳥の群れを見ることができました。最初の目的はまだ見ていない三角点を確認することだったのですが、思わぬおまけがついて良かったです。
11月29日の午後も畑の白鳥を見に行ってきました。最後はキツネが現れたため、皆飛び立って行きました。16時少し前だったので、ちょうど飛び立つ準備をしていたところでしたが。
For the walking in this afternoon of November 28, I took a new route to search another triangulation point. On the way, I could find flocks of swans resting in the field. It was very lucky.
In the afternoon of November 29, I went again to the upland field where I visited yesterday to see the flock of swans. The place swans stayed was a little apart from the yesterday' s site. I stayed there from around 15:00 to 16:00. Finally, a fox appeared and approached the swans. The scared swans flied back to their sleeping place.

Observation of the soil profiles in the forest of agricultural high school on a lower terrace. 農業高校低位段丘林土壌断面の観察。
12月2日の午前中、スコップと土壌調査道具を持って農業高校の森に行ってきました。昨日気付いた土壌断面をよく観察させて頂くためです。農業高校の方が穴を掘った理由はわかりませんが、土壌断面の観察に適した深さと幅に掘ってありました。ただし土壌断面の表面はガチガチに凍っていたので、スコップで削ってから観察しました。多分農業高校の職員の方による今年の作業はもう終わっていると思われたので、観察するだけなら許してもらえるだろうと思いました。断面は下半分が沖積層（4C, 5C層）で、その上に沖積の腐植層（4AC層）が乗っていました。断面上部は約9,000年前に降灰した樽前d火山灰から始まる火山灰層（3B, 3BC層）で、樽前dの腐植層（2A層）、約3,000年前に降灰した薄い樽前c火山灰層（1AC 層）、樽前cの腐植層（1A層）の順に堆積していました。農耕地でない土壌断面はめったに見ることができないので、大変有難い機会でした。土色や土性などは凍っていて観察できないので、土壌サンプルも少しずつ削って持ち帰りました。
In the morning of December 2, I went to the forest of Obihiro Agricultural High school to observe the soil profiles, carrying a shovel and the tools for soil survey. The pit was probably made by the staffs of the high school. Their work might have finished already, but the pit was left unburied. I thought that it will be allowed only to observe the profiles. The lower half of the profile was alluvial origin (5C and 4C layer), because the profile was located on the lower terrace. Around 5 cm thick humus layer (4AC) mixed with gravels covered the alluvial layer. The upper half was volcanic ash origin, starting from Ta-d volcanic ash (3B, 3BC, ca 9,000 YBP), overlain by its humus accumulated layer (2A), thin Ta-c volcanic ash layer (1AC, ca 3,000 YBP), and its humus accumulated layer (1A). I also brought some soil samples because it was difficult to check soil color and texture in the field. I was very lucky because we can rarely observe the undisturbed soil profiles. Before I went there, my wife said to me, "The pit must be a trap to hunt you". Yes, I was successfully trapped.
Soil profile 1 and 2.
Soil profile 3. Thin Tarumae-c volcanic ash layer can be observed at 35-38 cm depth.
Walk along the Urikai river to the west of OUAVM field. 畜大農場西側の売買川沿いを散歩。
12月6日の夕方から7日にかけて帯広ではたくさんの雪が降るというので、12月6日の午後は売買川の堤防沿いを散歩しました。畜大の一番南の圃場から畜大北交差点のローソン付近までずっと堤防の上を歩きました。草が枯れていたので歩きやすかったです。まず最初に白鳥の群れを見ました。ちょうどその時、スラリー散布車が来て、白鳥のいる畑にスラリーをまき始めました。白鳥は場所を移動していましたが、飛び去りはしませんでした。でも白鳥にとっては迷惑なことだったことと思います。売買川堤防沿いの河畔林の中に、形が牛に似ているので気になっていた石がありましたが、今日近寄ってみたら、こわれた牛の像でした。頭の部分も同様にこわれて近くに転がっていました。中は中空で、張り子のように外側をセメントで固めたものでした。かなり古いもののようです。誰が作って、どうして壊されてここに置かれたのか知りたくなりました。その他、散歩しているといろいろと面白いものが見つかりました。
According to the weather forecast, we will have a heavy snow from the evening of December 6 to December 7. Therefore, I went out for walking in the afternoon of December 6. I walked along the bank of Urikai river from the southernmost field of OUAVM to the crossing to the north of the university. First, I visited the field where swans were resting. While I was watching them, slurry applying vehicle came and applied the digested slurry in the field. Swans did not escape but just moved a little. However, they must have been troubled because the slurry smells bad and their feeding field became dirty. I walked further along the river bank, and found many interesting things, cracked wood trunk, rotted disposed tire, ruined statue of a cow, fallen tree infected by fungi, and etcetera. I enjoyed also the view of quiet river flow and splashing dams.

12月6日の夜から7日にかけて天気予報通りこの冬初めての本格的な雪となりました。午前中に一度家の周りを除雪し、16時から17時にかけてもう一度除雪しました。午前中除雪したあとにさらに20cm ほど積もっていました。過去にも12月7日は大雪がよく降っているようです。
From the night of December 6 to 7, we had a heavy snow in Obihiro. I had to remove the snow around my house two times a day in the morning and in the evening on December 7. Total depth of the fallen snow was around 30 cm. Also in the past, we had very often heavy snows on December 7.

Walk along the Urikai river after the heavy snow. 大雪後の売買川河畔を散歩。
12月6日の午後は畜大の一番南の圃場に行ってみましたが、白鳥はもういませんでした。さらに売買川沿いの河畔林も歩いてみました。野生動物の足跡はたくさんついていましたが、人の足跡はありませんでした。
In the afternoon of December 11, I walked to the southernmost field of OUAVM. I could not find swans any more there. I walked further to the riverside forest of Urikai river. There were many footprints of wild animals, but no footprints of human. Next visitor will find my footprints.

The view around my walking path has changed after the snow. Today I walked along the path in the forest of Obihiro Agricultural High School after two weeks or so. I could walk through the forest without wearing the snowshoes. In the latter half of the path, I could find only the footprints of foxes. After coming out from the forest I could see the beautiful evening view of the row of white birch and Kikanko river.
I have also added some more photos of my favorite trees taken during my walk in the following days.
Joined the wild birds survey of a volunteers group "Ezorisu_no_kai". エゾリスの会の鳥類調査に参加。
12月23日はエゾリスの会の鳥類調査に参加しました。帯広の森の中の既定のルートを歩いて、出会った鳥を記録するものです。私は百年記念館の学芸員さんのグループに入れてもらいました。学芸員さんは鳥の声を聞くだけで何の鳥かわかります。私が気づいた鳥の数の10倍くらいは見つけておられました。調査で大学の研究室の卒業生さんに再会しました。ハシブトガラ、シジュウカラ、ゴジュウカラ、ヒガラ、エナガ、キバシリ、キクイタダキ、アカゲラ、ヒヨドリ 、ハシブトガラスなどを観察することができました。
On December 23, I joined the wild bird survey activity held by a volunteer's group "Ezorisu no Kai (Hokkaido squirrel lover's group?)". I could also luckily meet the lady who graduated my laboratory 8 years ago.
Walking along Urikai river, Kikanko river and Satsunai river. 売買川、機関庫川、札内川沿いの散歩。
売買川堤防まで散歩。今年は雪が少ないので、真冬には普通歩いていけないところまで足を伸ばすことができます。１月５日には農業高校、畜大キャンパスを通って売買川の堤防を歩き、帰りは往路と違う道を通って帰ってきました。売買川の堰がしっかり凍っていました。その後の散歩の様子もこの項目に続けて載せることにしました。
Afternoon walk to Urikai river on January. Due to the very little snow in this year, I could walk to the place which is hardly accessible in normal years. The dam on Urikai river was frozen already. The views seen during my walk in the following days are also uploaded here.

Evening views from Seiryu town where I live (January 7). Photos taken during my evening walk are uploaded here. This morning, I had a lecture of soil science for the junior course students as a part time lecturer. After the lecture, I read the reports of students, and then joined a mini-volleyball game in the lunch break. I think, having a lecture once a week is very ideal for me, because I have enough time for preparing and reviewing the lecture.
Views along the bank of Kikanko river (January 7). 夕刻の散歩。今日は１時間目に非常勤講師（別科土壌作物栄養学）としての授業があり、ささやかな仕事始めとなりました。授業後１時間半ほど学生さんたちが提出したレポートを読み、昼休みにミニバレーをしてから帰ってきました。１週間に１度の授業というのは理想的です。
Elm trees (January 8). In the afternoon of January 8, I walked along Kikanko river to visit "Harunire" park where the symbolic elm tree of Obihiro city is growing. Then, I came home passing through the eastern bank of Satsunai river.

Satsunai river near the bridge of express highway (January 9). In the afternoon of January 9, I walked to the post office of Kawanishi town around 3 km far from my house, then came back walking along the bank of Satsunai river. On the way, I walked down to the river shore and watched the flow of the river. It was quiet and beautiful. The time to the post office was around 40 minutes and from the post office was around 1 hour. By car, it takes only 10 minutes from my house. When I become old enough, I will abandon driving, then it will become very difficult to go to post office.

Road on Satsunai river bank and elm trees (January 9). 川西郵便局に用事があったので散歩がてら歩いて行き、帰りは札内川の堤防を歩いてきました。行きが40分、帰りが１時間くらいかかりました。帰り道は川岸まで降りて川の流れを見ていたりしたので時間がかかりました。車で行けば10分以内のところですが、年をとって車を運転できなくなったら、歩くことも困難なので困るだろうなと思います。

This afternoon, I walked from the southern end of the university field to north along the bank of Urikai river. The river was totally frozen in this part. The evening glow on my way home was also beautiful (January 14). 今日は売買川沿いを畜大の圃場の南の端から北に向けて歩きました。歩き始めの部分では売買川は全面が凍っていました。堰の凍り具合も２週間ほど前に見た時よりもさらに進んでいました。帰り道は夕焼けが美しかったです。
