I had got the biggest parts of my machine done, and could fix them together and try it. There was an old stump by the barn-bridge from an aspen that had been blown down; I fixed my apparatus to that, and found at once that the saw would cut all right. Aha, now, what have you got to say? Here's the problem solved! I had bought a huge saw-blade and cut teeth all down the back; these teeth fitted into a little cogwheel set to take the friction, and driven forward by the spring. The spring itself I had fashioned originally from a broad staybusk Emma had given me, but, when I came to test it; it proved too weak; so I made another from a saw-blade only six millimetres across, after I had first filed off the teeth. This new spring, however, was too strong; I had to manage as best I could by winding it only half-way up, and then, when it ran down, half-way up again.
I knew too little theory, worse luck; it was a case of feeling my way at every step, and this made it a slow proceeding. The conical gear, for instance, I found too heavy when I came to put it into practice, and had to devise a different system altogether.
It was on a Sunday that I fixed my apparatus to the stump; the new white woodwork and the shining saw-blade glittered in the sun. Soon faces appeared at the windows, and the Captain himself came. He did not answer my greeting, so intent was he on the machine.
“Well, how do you think it will work?”'
I set it going.
“Upon my soul, I believe it will....”
Fruen and Frøken Elisabeth came out, all the maids came out, Falkenberg came out, and I let them see it work. Aha, what did I say?
Said the Captain presently:
