     At a certain time in our lives we consider every place as the possible sites (地点) for a house. I have

thus searched the country within a dozen miles of where I live. In imagination I have 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 gave for it.

     The real attractiong 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 fo 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

apples 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 thing I was ready for a large

farm. I believe that as long as possible it is better to live free and uncommitted (无牵挂的). It makes but little

difference whether you own a farm or not.
