The great fire that is kindled up is never let out, night or day, as long as the season lasts. Somebody is always cutting wood to feed it; somebody is busy most of the time gathering in the sap; somebody is required to watch the kettles that they do not boil over, and to fill them. It is not the boy, however; he is too busy with things in general to be of any use in details. He has his own little sap-yoke and small pails, with which he gathers the sweet liquid. He has a little boiling-place of his own, with small logs and a tiny kettle. In the great kettles the boiling goes on slowly, and the liquid, as it thickens, is dipped from one to another, until in the end kettle it is reduced to sirup, and is taken out to cool and settle, until enough is made to "sugar off." To "sugar off" is to boil the sirup until it is thick enough to crystallize into sugar. This is the grand event, and it is only done once in two or three days. [Illustration: A YOUNG SUGAR-MAKER] But the boy's desire is to "sugar off" perpetually. He boils his kettle down as rapidly as possible; he is not particular about chips, scum, or ashes; he is apt to burn his sugar; but if he can get enough to make a little wax on the snow, or to scrape from the bottom of the kettle with his wooden paddle, he is happy. A good deal is wasted on his hands and the outside of his face and on his clothes, but he does not care; he is not stingy. To watch the operations of the big fire gives him constant pleasure. Sometimes he is left to watch the boiling kettles, with a piece of pork tied on the end of a stick, which he dips into the boiling mass when it threatens to go over. He is constantly tasting of it, however, to see if it is not almost sirup. He has a long round stick, whittled smooth at one end, which he uses for this purpose, at the constant risk of burning his tongue. The smoke blows in his face; he is grimy with ashes; he is altogether such a mass of dirt, stickiness, and sweetness, that his own mother wouldn't know him. He likes to boil eggs with the hired man in the hot sap; he likes to roast potatoes in the ashes, and he would live in the camp day and night if he were permitted. Some of the hired men sleep in the bough shanty and keep the fire blazing all night. To sleep there with them, and awake in the night and hear the wind in the trees, and see the sparks fly up to the sky, is a perfect realization of all the stories of adventures he has ever read. He tells the other boys afterwards that he heard something in the night that sounded very much like a bear. The hired man says that he was very much scared by the hooting of an owl.
