Excerpt from Seasoning of Timber The wood next to the bark contains the most water. In the species which do not form heartwood the decrease toward the pith is gradual, but where this is formed the change from a more moist to a drier condition is usually quite abrupt at the sap wood limit. In Longleaf Pine, the wood of the outer 1 inch of a disk may contain 50 per cent of water, that of the next, or second inch, only 35 per cent, and that of the heartwood only 20 per cent. In such a tree the amount of water in any one sec tion varies with the amount of sapwood, and is therefore greater for the upper than the lower cuts, greater for the limbs than stems, and greatest of all in the roots. Different trees, even of the same kind and from the same place, differ as to the amount of water they contain. A thrifty tree contains more water than a stunted one, and a young tree more than an old one, while the wood of all trees varies in its moisture relations with the season of the year.

Excerpt from Selection and Seasoning of Wood Wood, to combine all the strength and durability of which its species is capable, should be taken from a tree which has reached maturity. A tree is not necessarily mature because it has attained such and such dimensions, but when it has passed through the two first periods of its existence, already alluded to, viz., that in which it increases in height, and that in which its woody tissue is strengthened, then it is mature. Thus, for example, there are upright yellow-woods which having been always overtopped by adjacent trees, have reached an advanced age without having attained a greater diameter than 8 or 9 inches. They are mature, and if converted into poles would prove very durable. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Timber: Its Strength, Seasoning, and Grading This book is intended primarily for engineers, manufacturers and users of lumber and of various special classes of wood material, and students of engineering and forestry. For such structural materials as steel, concrete, etc., there is a wealth of technical information in readily accessible form. Of wood the same can not be said. It is hoped that the present volume will serve to some extent to supply this deficiency. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Open-Tank Method for the Treatment of Timber The former theory of the process held that the hot preservative converted the moisture in the wood into steam and so expelled a large percentage of it, and that the cold bath condensed the steam in the pores of the wood and so formed a vacuum into which the preserva tive was forced by atmospheric pressure. In this way it was thought that the timber became seasoned just before or simultaneously with the entrance of the preservative. From this theory it also followed that green timber containing a large amount of moisture could be. Given a better treatment than seasoned timber, since the greater the amount of moisture in the wood the greater would be the vacuum formed when the vapor is driven off.

Excerpt from The Art of Developing Curing and Preserving Wood and Lumber Seasoning by What is known as the natural process was the first adopted for this purpose, and consisted in a slow drying out of the uid matter of the wood by exposing it to the action of the open air. As the result sought could only be effected by an exposure of the wood for many seasons, this mode of treatment was termed seasoning, and the treated wood was called seasoned.

MM. Bouquet de la Grye, Conservator of Forests, and A. E. Dupont, Naval Construction Engineer, have had logs weighed to ascertain the quantity of water Oak retains. The experiments were made at Toulon on Oak from Bourgogne, and the following averages have been determined: --Density of wood on arrival, or at leaving immersion basin, after remaining in store 1 year 2, 4 5., 6.. 10 It is the custom at Toulon to exclusively employ Oak timber for the ribs of ships which has been at least 10 years in store. At the expiration of that time the timbers are cut up, and allowed to dry a whole summer in the sun. Then they are worked and adjusted under a covered shed, where they remain from 4 to 6 years, the bolt holes bored and open. t From this it is seen that in receiving wood when no special understanding has been established on this point, it is well to wait...
