These are early american stools used that were made of scrap wood and used for children and milking cows. We find them often in the area and are great to have around the house. Attached is a photo of a green milking stool we have at our home.

こちらは木片でつくられた、牛の搾乳の時や子供用として使用された、アメリカ開拓時代のスツールです。この辺でよく見かけるもので、家の周りに置いておくのにちょうどよいものです。
