1portion called heartwood, which is the most solid. It is through this outer portion or sapwood that the sap chiefly ascends, and from its thus abounding more in saccharine and other matter, it is more perishable and sooner decays. In trees which have arrived at maturity, there is no distinction between the sap and heartwood, the wood being of the same texture throughout and almost uniform. The proper period for cutting trees is when the sap ceases to flow, and experience has proved the month of December to be the best time for this purpose, as the wood which has been cut during this month has been found to have always been of superior quality to any cut during the other months of the year. The ages of trees are generally known from the number of their concentric rings, but this is not an infallible index in every case. Some pines are known to contain 1200 of those circles, thus indicating an age of 1200 years, but the mean age of the pine, when it has reached maturity, is about 80 years. Maples are known which have reached the age of 600 years. If the wood to be used is in the original state, as a log transversely cut from the tree, we have merely to cut the wood to the centre, from the outer or bark side, and the pieces when so cut must be at least a quarter of an inch thick at centre of tree, and about an inch and quarter at the bark or outside, when the grain of the wood will be found to run in the requisite direction. Again, if the wood is in plank, it must be so sawn as that the required plate will have the concentric circles of the fibre of the tree passing at right angles to its surface, but a few minutes' explanation
