Smoky.

It stood in the middle of a vast yard behind the terribly strange house. And this tree rose up some one hundred feet in the air, taller than the high roofs and full and round and well branched, and covered all over with rich assortments of red and brown and yellow autumn leaves.

"But," whispered Tom, "oh, look. What's up in that tree!"

For the Tree was hung with a variety of pumpkins of every shape and size and a number of tints and hues of smoky yellow or bright orange.

"A pumpkin tree," someone said.

"No," said Tom.

The wind blew among the high branches and tossed their bright burdens, softly.

"A Halloween Tree," said Tom. 

And he was right.

There must have been a thousand pumpkins on this tree, hung high and on every branch. A thousand smiles. A thousand grimaces. And twice-times-a-thousand glares and winks and blinks and leerings of fresh-cut eyes.

And as the boys watched, a new thing happened.

The pumpkins began to come alive.

One by one, starting at the bottom of the Tree and the nearest pumpkins, candles took fire within the raw interiors. This one and then that and this and then still another, and on up and around, three pumpkins here, seven pumpkins still higher, a dozen clustered beyond, a hundred, five hundred, a thousand pumpkins lit their candles, which is to say brightened up their faces, showed fire in their square or round or curiously slanted eyes. Flame guttered in their toothed mouths. Sparks leaped out their ripe-cut ears.

Halloween.
