专利的

He divides his own into two categories "and" noncommercial work.

他把自己的工作分为两类，并且是"非商业化"的。

The farmer can work alone in the field or the woods all day, hoeing or chopping, and not feel lonesome, because he is employed; but when he comes home at night he cannot sit down in a room alone, at the mercy of his thoughts, but must be where he can "see the folks," and recreate, and, as he thinks, remunerate himself for his day's solitude; and hence he wonders how the student can sit alone in the house all night and most of the day without ennui and "the blues"; but he does not realize that the student, though in the house, is still at work in his field, and chopping in his woods, as the farmer in his, and in turn seeks the same recreation and society that the latter does,though it may be a more condensed form of it.

农夫可以一整天，独个儿地在田地上，在森林中工作，耕地或砍伐，却不觉得寂寞，因为他有工作；可是到晚上，他回到家里，却不能独自在室内沉思，而必须到"看得见他那里的人"的地方去消遣一下，用他的想法，是用以补偿他一天的寂寞；因此他很奇怪，为什么学生们能整日整夜坐在室内不觉得无聊与"忧郁"；可是他不明白虽然学生在室内，却在他的田地上工作，在他的森林中采伐，像农夫在田地或森林中一样，过后学生也要找消遣，也要社交，尽管那形式可能更加凝炼些。
