This should be carefully attended to when the sugar is graining.

The mature state of the boiling is known by taking a little of the syrup from the boiling stick, and trying if it ropes or draws into a thread between the finger and thumb ; then it should be put into a tub or cooler, and stirred incessantly until the grain can be felt, when it is in a fit state to be poured into the moulds.

Molasses and vinegar. -- When the trees of the second tapping become poor, which may be about the 31st, of March, or perhaps not till the 10th of April, the number of fresh tapped trees will yield a sap, of which may be made good molasses, and excellent vinegar.

Rum has also been made of an exceeding good quality from the rich sap.

GENERAL OBSERVATIONS.

In maple plantations, it may bb useful to cut down all other timber which gfow intermixed with the sugar trees, and also those of that species which are not thriving.

It is not yet ascertained from experience, how long a tree may be tapped with success. -- But there are instances among old settlers on the North river of trees being tapped for 50 years, and still continue to yield their sap in season, the same as new trees ; and it is even asserted by persons of some experience, that these trees become more valuable, yielding a sap of a richer quality the more they are tapped.
