At a certain time in our lives we consider every place as the possible site(地点) for a house. I have thus searched the country within a dozen miles of where I live. In imagination Ihave bought all the farms, one after another, and I knew their prices.

The nearest thing that I came to actual ownership was when I bought the Hollowell place. But before the owner completed the sale with me, his wife changed her mind and wished to keep it, and he offered me additional dollars to return the farm to him. However, I let him keep the additional dollars and sold him the farm for just what I had given for it.

The real attractions of the Hollowell farm to me were its position, being about two miles from the village, half a mile from the nearest neighbor, bounded(相邻) on one side by the river, and separated from the highway by a wide field. The poor condition of the house and fences showed that it hadn’t been used for some time. I remembered from my earliest trip up the river that the house used to be hidden behind a forest area, and I was in a hurry to buy it before the owner finished getting out some rocks, cutting down the apple trees, and clearing away some young trees which had grown up in the fields. I wanted to buy it before he made any more of his improvements. But it turned out as I have said.

I was not really troubled by the loss. I had always had a garden,but I don’t think I was ready for a large farm. I believe that as long as possible it is better to live free and uncommitted(不受约束的). It makes but little difference whether you own a farm or not.
