Thanksgiving came and went, and a week later there came a fairly heavy fall of snow.

"Hurrah! winter is knocking at the door at last!" cried Sam joyfully. "Now for some snowballing, skating, and all the rest of the winter fun."

Snowballing was already going on, and the white balls were flying in all directions. Dick had his hat taken off by Frank, and in return filled Frank's ear with snow. Tom and Fred got into a regular war at close quarters, and in the end Tom threw his opponent flat and stuffed snow down his neck. But then Larry came up with a huge cake of snow and nearly smothered Tom, and then a dozen leaped in, and a good-natured melee resulted, lasting for the rest of the playtime.

It was very cold that night, and two days later the ice on the lake was two inches thick. Still the captain made the boys wait until the following Saturday, when the ice was strong enough to bear a horse.

In the meantime skates had been brought out and polished up, and soon the edge of the lake was alive with skaters, all moving swiftly from one spot to another, and shrieking and laughing at the top of their voices. George Strong, the assistant master, also came down and showed some of the older boys how to cut fancy figures. Dick was a good skater, and took to the fancy figures with ease. As for Tom and Sam, they preferred straight skating, and entered half a dozen trials of speed down the lake to the old boathouse and back.

"If it gets much colder, so that the ice thickens, I am going to build an ice-boat," said Frank to Dick that night. "Captain Putnam said I could have all the old lumber I want. You know the carpenters left a lot when they fixed over that burnt part of the Hall."

"Hurrah, an ice-boat!" cried Dick. "Just the thing. Let me help, you, Frank. Perhaps the captain will let us have an old camping-out tent for a sail."

"Yes, I've asked him about that already, and he told Mrs. Green to get me one from the storehouse."

"And what about nails and runners?"

"Peleg Snuggers is going to give me the nails and lend me the tools. The runners I will have to buy down to the blacksmith shop."
