The Sea Wolf Jack London

I remember thinking how comfortable it was, this division of labour which made it unnecessary for me to study fogs, winds, tides, and navigation, in order to visit my friend who lived across an arm of the sea.  It was good that men should be specialists, I mused. 

The peculiar knowledge of the pilot and captain sufficed for many thousands of people who knew no more of the sea and navigation than I knew.  On the other hand, instead of having to devote my energy to the learning of a multitude of things, I concentrated it upon a few particular things, such as, for instance, the analysis of Poe’s place in American literature—an essay of mine, by the way, in the current Atlantic. 

Coming aboard, as I passed through the cabin, I had noticed with greedy eyes a stout gentleman reading the Atlantic, which was open at my very essay.  And there it was again, the division of labour, the special knowledge of the pilot and captain which permitted the stout gentleman to read my special knowledge on Poe while they carried him safely from Sausalito to San Francisco.
