So that in an oak table, thedarker, shaded parts are the spring-wood, the hghterunicolored parts the summer-wood. On closer examina-tion of the smooth cross-section of oak, the spring-woodpart of the ring is found to be formed in great partof pores; large, round, or oval openings made by the cutthrough long vessels. These are separated by a grayish. radial section; TS, tan-gential section; mr,medullary or pith ray;a, height; h, width; ande, length of pith ray. 32 SEASONING OF WOOD Mmm imlM
