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 attached to a metal shaft. The head is strung with nylon or leather strings to form a pocket. The dimensions of the stick (length, width, sidewall height, and depth of the pocket) are governed by league rules, such as NCAA rules for collegiate players or FIL rules for international players.
