Wood the growth of the young timber in open stands after the old trees have been removed is more rapid than in trees in a closed forest, and in the manufacture of articles where strength is an important consideration such "second-growth" hardwood material is preferred. This is particularly the case in the choice of hickory for handles and spokes. Here not only strength, but toughness and resilience are important. The results of a series of tests on hickory by the U.S. Forest Service show that: The effect of rate of growth on the qualities of chestnut wood is summarized by the
Lacrosse stick Rules Committee. Questions have arisen regarding the alteration of the shaft circumference. The circumference of the shaft cannot exceed 3 1/2". To be clear, added tape to the shaft must not make the shaft exceed this circumference measurement. In women's lacrosse, the stick dimensions are similar except the pocket depth is much shallower. NCAA rules dictate that the head of a woman's stick may be from seven to nine inches wide, and must be strung traditionally, with a pocket formed by a grid of leather strings. Nylon mesh stringing, permitted in men's sticks, is not permitted in women's sticks; however,
