"No," said both Jock and George. "You said not to toll that last bag till we saw whether there was water enough to grind it."

"But you declared that there was water enough, and tolled it!" cried Halstead.

Addison and I could not say positively whether they had tolled it or not; and they appeared to think that it had not been tolled. The point was argued for some moments; finally it was agreed to compromise on it and let them have one measure of toll out of it. So there was two quarts of loss or gain, whichever party was in error.

When the last bagful was nearly ground and the hopper empty, all save a pint or so, Jock and George ran to shut the gate and stop the mill.

"Hold on!" cried Addison. "That isn't fair. There's two quarts in the stones yet; we shall lose all that on top of toll."

"But we must shut down before the corn is all through the stones!" cried Jock, "or they'll get to running fast and grind themselves. 'Twon't do to let them get to running fast, with no corn in."

"Well, don't be in such haste about it," urged Addison. "Wait a bit till our grist is nearer out."

They waited a few moments, but were very uneasy about the stones, and soon after the last kernels of corn had disappeared from the hopper, they pulled the ash pin to let the gate fall. It was then discovered that from some cause the gate would not drop. The boys thumped and rattled it. But the water still poured down on the wheel. By this time the meal had run nearly all out of the millstones and they revolved more rapidly. The young millers were now a good deal alarmed, and, running out, climbed up the dam and looked into the flume, to see what was the matter with their gate.

"It's an old shingle-bolt!" shouted Jock, "that's floated down the pond! It's got sucked in under the gate and holds it up! Fetch the pike-pole, George!"

George ran to get the pike-pole; and for some moments they tried to push, or pull, the block out. But it was wedged fast and the in-draught of the water held it firmly in the aperture beneath the gate. It was impossible to reach it with anything save the pike-pole, for the water in the flume over it was four or five feet deep.
