"Doctor," I exclaimed, "I like that idea of the social fund immensely! It makes me understand, among other things, the completeness with which you seem to have outgrown the wages notion, which in one form or other was fundamental to all economic thought in my day. It is because you are accustomed to regarding the social capital rather than your day-to-day specific exertions as the main source of your wealth. It is, in a word, the difference between the attitude of the capitalist and the proletarian."

"Even so," said the doctor. "The Revolution made us all capitalists, and the idea of the dividend has driven out that of the stipend. We take wages only in honor. From our point of view as to the collective ownership of the economic machinery of the social system, and the absolute claim of society collectively to its product, there is something amusing in the laborious disputations by which your contemporaries used to try to settle just how much or little wages or compensation for services this or that individual or group was entitled to. Why, dear me, Julian, if the cleverest worker were limited to his own product, strictly separated and distinguished from the elements by which the use of the social machinery had multiplied it, he would fare no better than a half-starved savage. Everybody is entitled not only to his own product, but to vastly more--namely, to his share of the product of the social organism, in addition to his personal product, but he is entitled to this share not on the grab-as-grab-can plan of your day, by which some made themselves millionaires and others were left beggars, but on equal terms with all his fellow-capitalists."

"The idea of an unearned increment given to private properties by the social organism was talked of in my day," I said, "but only, as I remember, with reference to land values. There were reformers who held that society had the right to take in taxes all increase in value of land that resulted from social factors, such as increased population or public improvements, but they seemed to think the doctrine applicable to land only."

"Yes," said the doctor, "and it is rather odd that, having hold of the clew, they did not follow it up."

We Look Over My Collection Of Harnesses.

Wires for light and heat had been put into the vault, and it was as warm and bright and habitable a place as it had been a century before, when it was my sleeping chamber. Kneeling before the door of the safe, I at once addressed myself to manipulating the dial, my companions meanwhile leaning over me in attitudes of eager interest.

It had been one hundred years since I locked the safe the last time, and under ordinary circumstances that would have been long enough for me to forget the combination several times over, but it was as fresh in my mind as if I had devised it a fortnight before, that being, in fact, the entire length of the intervening period so far as my conscious life was concerned.

"You observe," I said, "that I turn this dial until the letter 'K' comes opposite the letter 'R.' Then I move this other dial till the number '9' comes opposite the same point. Now the safe is practically unlocked. All I have to do to open it is to turn this knob, which moves the bolts, and then swing the door open, as you see."

But they did not see just then, for the knob would not turn, the lock remaining fast. I knew that I had made no mistake about the combination. Some of the tumblers in the lock had failed to fall. I tried it over again several times and thumped the dial and the door, but it was of no use. The lock remained stubborn. One might have said that its memory was not as good as mine. It had forgotten the combination. A materialistic explanation somewhat more probable was that the oil in the lock had been hardened by time so as to offer a slight resistance. The lock could not have rusted, for the atmosphere of the room had been absolutely dry. Otherwise I should not have survived.
