1.Not long ago I was looking over one of the greatsaw-mills on the Mississippi River，in company with themanager of the mill.As we came to one room he said：“I want you to notice the boys in this room，and I will tell you about them afterwards.”
2.There were some half-dozen boys at work on saws，with different machines，some broadening the points of the teeth，some sharpening them，some deepening thenotches between them.There was one lad who stood leaning up against a bench，not trying to do anything.
3.After we had passed out of the room，the man-ager said to me：“That room is my sieve.The fine boysgo through that sieve to higher places and higher pay.The coarse boys remain in the sieve，and are thrown out as of no use for this mill.”
4.Then he explained what he meant.“If a boy wants to work in the mill，I give him the job of keeping the men in all parts of the mill supplied with drinking-water.That is the lowest position，and draws the lowest pay.I say to that boy，‘When you have nothing else to do，go into this room，and then I shall know where to find you when I want you.’
5.”But there is a much more important reason why I send him into this room.In a business like this our men are constantly changing.A good deal of the work，as you will see by watching the machines and those who manage them，requires much attention and skill.I must therefore look out for the best men to put into the highest positions.
6.“Now I put the water-boy into this room where there are several kinds of work being done.There are pieces of broken saws lying about，and some of the tools that are used in sharpening and mending them.
7.”I watch that boy.If he begins handling thesebroken saws，looking them over，trying them，practisingon them with the tools there，watching the other boys at their machines，asking questions about how the work is done，and always making use of his spare time in oneway or another，why，that boy is very soon promoted .
8.“He is first put to work on some of the machines in this room，and afterwards on those that require greater skill，and is pushed ahead as rapidly as there are openings for him.He soon goes to a better position and better pay，and I get a new water-boy.He has gone through the sieve.
9.”But there is another kind of boy.When he has time to spare，he spends it in doing nothing.He leans up against the benches，crosses one leg over the other，whistles，stares out of the window，no doubt wishing he was outside，and watches the clock to see how soon he can get away.If he talks with the other boys，it is not to ask questions about their work，but to waste their time with some nonsense or other.
10.“I often do all I can to help such a boy.I push the tools under his very nose.I ask him questions about them.I talk with him about his plans for the future.Ido all that I can to awakensome kind of life in him.
has not，he is simply useless.I don‘t want such a boy in this mill，even as a water-boy.”
