“I see,” said Irv. “It’s the biggest endless chain imaginable. Thousands? Why, thousands had a hand in it before you even get to the farmer—the men who made the tools, and the men who made the tools that made the tools, and so on back to the very beginnings of creation. And if we face about, there are the men that ran the railroads which hauled the wheat to mill, and the millers, and all that. Oh, the thousand are easy enough to make out.”

“Yes,” said Ed, “and then the railroads and the mills had to be built. The men that built them, the engineers, mechanics, and laborers, all helped to give me my two slices of toast. So did the men behind them, the men who made their tools and their materials, the woodsmen who chopped trees for ties, the miners who dug the iron, the smelters, the puddlers, the rolling-mill men, who wrought the crude ore into steel rails; then there are all the men who made the locomotives, and the cars, and the machinery of the mills, and—”

“Oh, stop for mercy’s sake,” said Will. “It’s no use to count. There aren’t thousands, but millions of them. And of course the same thing is true of our clothes, our shoes, and everything else.”

“But with so many people’s work represented in it,” asked Irv, reflectively, “why isn’t that piece of toast an enormously costly affair?”

“Simply because so many people’s work is represented in it,” answered Ed. “If one man had to do it all for himself, it would never be done at all. Just imagine a man set down on the earth with no tools and nobody to help him. How much buttered toast do you suppose he would be able to turn out in a year? Why, before he could get so much as a hoe he would have to travel hundreds of miles, dig some iron and coal, cut wood with which to convert the coal into coke, melt the iron out of its ore, change it into steel, and shape it into a hoe. Why, even a hoe would cost him a year’s hard work or more, while a wagon he could hardly make without tools in a lifetime. Now he can earn the price of a hoe in a few hours, and the cost of a wagon in a few days or weeks, simply because everybody works for everybody else, each man doing only the thing that he can do best.”

“Then we all work for each other without knowing it,” said Will.

“Of course we do. When we fellows were diving for that pig-iron, we were working for the thousands of people who will use or profit by the things that somebody else will make out of that pig-iron and—”

“And for the somebody else,” said Irv, “that will make those things out of the pig-iron, and for all the ‘somebody elses’ that work for them, and so on in every direction! Whew! it makes my head swim to think of it. But what a nabob you are, Ed! Just think! Thousands and even millions of people are, at this moment, at work to make you comfortable!”

“Yes, and each one of the millions is at work for all the others while all the others are at work for him. Theorists sometimes dream out systems of ‘coöperative industry,’ hoping in that way to better men’s condition. But their very wildest dreams do not even approach the complex and perfectly working coöperation we already have in use.”
